Points of connection to basic transport pipelines, direct lines and distribution networks which aim to bring the gas to a single final consumer: the minimum value of the pressure is set at 16 bar;

Basic transport pipeline connection points for other basic or secondary transport pipelines:

If the connection point is located within a malside system, the minimum pressure value is set to 40 bar;

If the connection point is in a linear extension from a mesh network with a single flow direction, the minimum pressure value is set to 30 bar.

Secondary transport pipeline connection points: The minimum pressure value is set to 16 bar.

In any event, the distribution network operator will report, in a transparent and non-discriminatory manner, to customers with consumption exceeding 100 GWh/year of the pressure levels it can guarantee in the various network zones.

In case a user needs supply pressures above those established in each range, particular agreements will be reached between the parties, on objective, transparent and non-discriminatory basis.

2.6 General requirements for the use of LNG regasification plants.

2.6.1 Operating minimum level. Heels. -All users accessing a LNG regasification plant will contribute an amount of LNG from their property in order to contribute to the minimum operational level (heels) of the LNG tanks of the regasification plant. As an initial value of this amount, 9% of the storage capacity in LNG tanks will be taken, which will be distributed among the users of the plant according to its contracted regasification capacity, with monthly revisions. This value must be approved annually.

The gas contribution shall be made over the course of the 15 days after the date of the first delivery related to the capacity procurement, in accordance with the procedure agreed in the operating manual.

The amount contributed to the minimum level of filling will remain immobilized in the plant, without the subjects being able to make use of it.

As a general rule, in the event of termination of the contract, the volume of gas owned by the subjects made available to the carrier and retained by the carrier, in order to contribute to the minimum operational level of the LNG tanks of the regasification plant shall be reintegrated into its holders before the termination of the contractual period, and if this is possible, in another period and in such a way as to be agreed by the parties.

Likewise, and in any event, the subjects may give up their rights to the gas retained by this concept to any other authorized subject and with contract in force, exonerating the carrier of the obligation to return the same.

2.6.2 Storage for commercial operation in LNG regasification plant tanks.-Storage for commercial operation in regasification plant tanks may not exceed the useful capacity of the tanks and shall be understood to be located in these, provided that the useful capacity exceeds five days included in the regasification toll.

2.6.3 Storage in tanks of LNG regasification plants above the toll included. -It will be possible to contract the LNG storage service in plant, additional to the one included in the regasification toll, by the capacity required for the unloading of ships used for the transport of LNG, with the limit of the maximum capacity to attract.

However, in the event of insufficient capacity or technical reasons to prevent this, a request to this effect may be refused. In any case, in order to facilitate the operation, the Technical Manager of the System, in coordination with the affected carrier, may decide a variation on the place and form in which the user has available the natural gas corresponding to the LNG discharged, provided that this does not entail any cost or injury to the user.

Additionally, the subjects with the right of access will be able to contract storage capacity, above the storage included in the toll, in LNG tanks of regasification plants, provided there is capacity available.

2.6.4 Mermas and self-consumption. -The operator of the LNG regasification plant will assume in front of the users the risk of damage or loss of the gas, since it is accepted at the points of unloading of ships until it is delivered in the corresponding connection point.

Of all the gas delivered by the subjects at the point of unloading of ships, the operator will retain at the moment of delivery, in terms of mermas and self-consumption, the amount that is established.

The System Technical Manager with the information provided by the operators of the facilities will carry out the studies to monitor the evolution of the coefficients of losses and self-consumption assigned to each installation.

The Technical Manager of the System will propose, before October 15 of each year, to the General Directorate of Energy Policy and Mines for approval, prior to the report of the National Energy Commission, the amount to be retained in concept of mermas and self-consumption.

2.6.5.2 Requirements for unloading/loading of tankers.-The verification of compatibility between ships and ports, arms and moorings for each LNG regasification plant, taking into account their respective characteristics, will lead to a contractual agreement granting the ship's right of access to the LNG discharge at the considered plant

Still, the first time a ship will unload/load at a terminal of a LNG regasification plant, it must be qualified for this purpose by the plant holder through a compatibility procedure, agreement with the corresponding detail protocol.

The owner of the installation will be responsible for the issue of a compatibility certificate for each new ship that is to be downloaded for the first time in a terminal and will send a copy of it to the System Technical Manager, to the less, 48 hours before the start of the first discharge. The information received by the Technical Manager of the System will be available to all LNG regasification plants and marketers. In addition, periodic inspections or amendments to be declared on a ship or a terminal shall be carried out to verify that the discharge compatibility is maintained.

The Ship-Shore Safety Procedure established by the International Maritime Organization, or equivalent standard of recognized international prestige, will be followed.

2.6.6 Liquefied Natural Gas (LNG) Tanker Load Requirements. For the purposes of these standards, the following definitions shall apply:

Loader-Downloader: the natural or legal person under whose responsibility the merchandise is loaded and unloaded.

Shipper: the natural or legal person whose order and account is made to send the dangerous goods, for which transport is performed as such in the transport document.

Carrier of tanks: the natural or legal person who assumes the obligation to carry out the transport, counting for this purpose with his own business organization.

Transport of tanks: any road tanker transport operation carried out in whole or in part on public roads, including the loading and unloading of dangerous goods. The transport operations carried out in full within the perimeter of a closed site are not included.

The transport and handling of Liquefied Natural Gas (LNG) in tanks, as well as the relations between the interveners, must comply with the current legislation.

The charger (being understood as such to the operator of the regasification plant) will refuse the load in case of not being properly accredited and that, both driver and vehicle, have the permits and authorizations necessary to be able to carry out the intended transport, in accordance with the rules applicable for the carriage of dangerous goods by road. Before making the first LNG load by means of a new tank, the tanker carrier shall make available to the charger all the documentation laid down in the relevant regulations and in the agreements between the parties.

2.7 General requirements for using underground storage.

2.7.1 Storage and injection capacity in storage. -Users will have the right to dispose of each storage capacity for gas injection and extraction, proportional to the contracted storage capacity for the market liberalised or reserved for the market at tariff with respect to the storage capacity.

This available capacity will be limited by the technical constraints necessary to be able to meet the requirements of the system operation related to the coverage of winter modulation and unforeseeable events. which may affect the security of supply of the system, in particular during the winter season.

The limitation of injection and extraction capacity will not be applicable whenever there are technical possibilities to increase them.

2.8 Principles for the calculation of capacity of the facilities. -As indicated in this section, the rules and procedures for determining the capacities will be developed in the corresponding detail protocol. maximum, useful and available from the facilities constituting the gas system.

For the calculation of the useful capabilities, account will be taken not only of the design parameters of the same, but also those operational aspects that decrease or limit it and which are, among others: the service factors, the concurrency, the operating and security margins, the period of the year to which the guarantee capacity and pressure are concerned.

regasification plant. -In regasification plants, the capacity of the transmission system to be distinguished between the transmission system and the design pressure of the same and the ability to discharge the metaneros vessels, if this is the case. limitative.

The normal operating capacity will be the useful one and will be calculated based on the emission and discharge equipment that is installed in the plant, taking into account its operating limits, safety, backup equipment, etc.

Where appropriate, there may be a capacity higher than the maximum or useful, corresponding to the operating capacity at peak emission, with the total or partial use of reserve equipment.

LNG cargo to ships.-The possibility and capacity of LNG cargo to ships will be established and published from each regasification plant; likewise about the cold putting of ships and transhipments.

Tank Loading Capacity. -It will be calculated taking into account the capacity of the pumping equipment installed in the regasification plant, taking into account its limits of operation and safety, and within the values authorized.

Underground storage. -An injection capacity and storage capacity and storage capacity will be distinguished:

Injection and extraction capacity: The injection capacity will be calculated taking into account the compression equipment installed at the facility, its operating and safety limits, as well as the gas delivery pressure in the the transport pipeline to which it is connected and the existing pressure on the storage itself.

The extraction capacity is a function of the amount of gas in storage at any time and will be calculated taking into account the gas treatment equipment of the plant, its operating and safety limits, as well as as the gas output back pressure on the transport pipeline to which it is connected.

Storage capacity:

Maximum storage capacity: This is the amount of natural gas contained in a storage when the pressure of the storage matches the maximum operating pressure.

Maximum removable amount: It is the difference between the maximum storage capacity and the amount to secure storage in conditions that allow a future recovery of its capacity, taking into account, that the gas extracted can be introduced into the network of pipelines at the normal operating pressure, either directly or through compression elements. The part corresponding to the removable mattress gas by mechanical means can only be extracted in emergency situations.

Transport pipelines.-The maximum capacity of a transport pipeline is defined as the maximum gas flow that can be vehicular through the same in m³(n) /h, taking into account the input pressure is equal to the maximum operating pressure which is legally authorised at the start of the pipeline or the guarantee pressure at the point of entry of the pipeline, maintaining the most restrictive guarantee pressure at all points of the pipeline (delivery points) or intermediate compression station aspiration).

In secondary transport pipelines it shall be considered as input pressure to be guaranteed at the point of delivery.

The expected levels of demand for summer, winter and peak periods should be taken into account and for each of these scenarios the concurrency factors and operating and security margins will be considered. set.

In relation to consumption for these outputs, demand scenarios will be taken into account for summer, winter and peak times, in this way the base scenarios will be created, from which the simulation calculations will be carried out. capacity. This will be done by establishing the capacity according to the consumption that is incrementally added.

In addition to these scenarios, the concurrency factors and security margins that are set will be considered.

In the case of linear and Mallados pipelines, simulation systems that provide for general and accepted hydraulic models in the gas industry will be used for calculations.

Distribution pipelines.-The maximum capacity of a distribution pipeline of a given pressure level is defined as the gas that can be compressed through it, in m³(n) /h, maintaining the pressure of more restrictive warranty on all points of the same.

This capacity depends on the regulatory pressure in the network/s, as well as the existing load losses. The determination of the available capacity of a network shall be carried out by assessing the additional flow rate that can be delivered to the minimum pressure point/s, by introducing the gas at the maximum pressure possible and maintaining the minimum pressure of warranty.

2.9 Inavailabilities in transport facilities. -In the event of unavailability, the operator of the unavailability facility must communicate to the users with the capabilities contracted with it and the operators facilities connected to yours which is their available capacity for the duration of the situation. In order to minimise their impact, the inavailabilities will be communicated as far as possible. In all cases, the operator of the facilities affected by the unavailability shall make every effort to minimise the duration of the facility and its effects on the normal provision of the service.

If, as a result of the unavailability raised, the capacity of supply to end users is reduced, the remaining capacity will be distributed, in coordination and supervision of the System Technical Manager, between the subjects concerned in accordance with objective, transparent and non-discriminatory criteria.

2.10 Inavailabilities in distribution facilities. -In the event of unavailability, the operator of the facility with unavailability will communicate to the users with contracted capabilities and to the operators of the facilities connected to their own available capacity for the duration of the situation. In order to minimise their impact, the inavailabilities will be communicated as far as possible. In all cases, the operator of the facilities affected by the unavailability shall make every effort to reduce the duration of the facility and its effects on the normal service provision.

In the event that, as a result of the unavailability raised, the supply capacity is reduced to the end-users, the remaining capacity will be divided, if appropriate, between the affected subjects on the basis of criteria objectives, transparent and non-discriminatory.

2.11 Transparency of the conditions of access.-The Technical Manager of the System and the operators of the facilities must publish in their pages on the Internet all those agreements, manuals, models of contract or procedures to supplement the provisions of these System Technical Management Standards or their development protocols, as well as any information necessary to ensure transparency in the technical management of the system.

None of the content of the agreements entered into between the subjects of the system may be contrary to the provisions of the legislation in force.

The holders of the regasification, storage and connection facilities to international pipelines will publish with the periodicity that the contracted capacity is established, reserved and available in each of these facilities, distinguishing the capacity allocated to the access contracts and the capacity reserved for the market at tariff level.

A ship's discharge schedule may only be modified or eliminated for justified reasons and prior knowledge and acceptance of the holder of the regasification plant and of the System Technical Manager, unless it is put in place. danger system security.

A record will be created, maintained by the System Technical Manager, of unallocated, unallocated and free ship discharge windows on each of the plants, free of charge for plant and plant holders. marketers.

In the case of the release of a download window on a site, the reassignment priorities to another user of that download capacity will be as follows:

That request that, being in the record of unscheduled download requests from the available window, the requested download date that is closest to the one that has been released.

That request that, in the record of unscheduled download requests from another site, the requested download date that is closest to the one that has been released.

In the event that no request exists in any of the regasification plants, it will be brought to the attention of all users with input capacity.

This released capacity reassignment procedure will be coordinated by the System Technical Manager.

In the monthly ship download schedule it will be provided:

Date of issue;

The identifier of the subject that performs the programming;

Programming type (periodicity);

Installation to which you apply;

Quantity and quality for each month;

Identification and type of ship with which transports will be performed.

In monthly gas output programming to transport networks will be provided:

Date of issue;

The identifier of the subject that performs the programming;

Installation to which you apply;

Quantity: quantity in kWh/month and maximum hourly quantity in m³(n) /h for each month.

The monthly LNG tanker loading schedule will be provided:

Date of issue;

The identifier of the subject that performs the programming;

Programming type (periodicity);

Installation to which you apply;

Quantity: in m³ GNL/month and/or LNG tankers per month.

With all the schedules received up to the twentieth day, on the 25th of each month, the operator of each LNG regasification plant will set and communicate the date of unloading of each vessel (window). Each user shall receive the information relating to their respective vessels.

The ship discharge procedure will be detailed in the corresponding detail protocol.

On a daily basis, users will provide LNG regasification plant operators with any modifications to the monthly assigned download program.

3.6.3 Viability of ship discharge schedules. -operators of regasification plants may refuse to carry out the discharge schedules of vessels made by the users of their facilities, when endanger the safety of the system or when the level of its stock at the time of the start of the discharge at the scheduled plant is higher than the higher value of the following two quantities (expressed in number of days of capacity contracted regasification, with a 100% utilization factor):

Storage included in the regasification toll.

The result of dividing the total LNG storage capacity of the plant (m³ of LNG) between the total regasification capacity that is contracted (in m³ GNL/day).

In any case, all ship-discharge programming will be limited by the physical storage capacity available in LNG tanks at any time, although carriers, in coordination with the System Technical Manager, they will do their best to make the programming feasible by coordinating the operation of all the plants of the system.

The provisions of this point will also apply when due to a commercial LNG exchange in tank, or to any other cause, the level of storage of a certain user of the regasification plant will be greater than the higher value of the previously set.

3.6.4 Publication of ship discharge schedules. -Once the monthly schedule of unloading of liquefied natural gas vessels in regasification plants by operators, the Technical Manager of the System will publish the following information for each site:

In the case of monthly schedules, if the difference between inputs and outputs to the transport system could, in the opinion of the System Technical Manager, affect the operating system's operating system for excess or defect.

NGTS-05 "Measurement"

5. Measurement

5.1 Purpose and scope of measurement. -The purpose of the measurements is to determine the quantity and quality of the gas flows in all those points of the gas system where it is legally required or considered necessary, to the purpose of accurately and correctly performing the following functions and activities:

Comprehensive control and management of the operation of the gas system.

The qualms and balances to which the corresponding System Technical Management Standards refer.

The billing of gas deliveries made between the subjects operating on the system.

The billing of supplies to end consumers by distributors and marketers.

The billing of ATR services (third-party access to gas installations) provided by the operators of the facilities that make up the system to the users of the facilities.

The tracking of schedules and nominations as well as the analysis of the viabilities of the same.

To this end, the scope of these rules is extended to all those aspects that are required of measurement equipment and measurement procedures, as well as those related to the metrological control established in the Law 3/1985, of March 18, of Metrology. If there is no specific legislation in this respect, the relevant UNE standard will be met.

In addition, to be able to carry out the necessary monitoring, measurements and analysis will be carried out to determine the quantity and quality of the gas transported, regasified, unloaded, distributed or stored by the facilities. corresponding. A historical record of measurement and analysis results will be maintained for four years.

The measurement facility will have the necessary equipment for the correct measurement of the quantity delivered and, where applicable, the quality of the gas.

Generally, the measurement facilities will not have the equipment for determining the characteristics of the delivered gas. In this case, the parameters necessary to establish the quality will be obtained from another point of the system, accepted by the involved subjects, that if you have this type of equipment and that you are receiving gas of equal or similar quality and that you count with relevant equipment.

Only the quality measurement and measurement equipment and procedures that are expressly referenced in the corresponding measurement protocol will be valid. Such equipment and procedures shall be subject to the State's metrological control and shall, where appropriate, comply with the UNE-EN standards applicable to them.

To convert the unit of measurement for counters that lack correction equipment, m³, to the unit of measure set in the rates and tolls, kWh, a coefficient, which must be in the conditions of measurement of the point of supply and the higher calorific power (PCS) in phase gas measured at 0 ° C and 1.01325 bar. These coefficients must be detailed in the turnover of the sale of gas for sale at tariff and in the price of the tariffs and tolls as variables which serve as the basis for the calculation of the resulting quantities. For these purposes, the Technical Manager of the System shall communicate monthly to the National Energy Commission and the distribution and marketing companies the coefficients to be applied to the customers in the different geographical areas, as well as the justification of the same. The distribution companies will publish the PCS information and correction factors applicable to consumers for each municipality.

Quality measurement and analysis systems and equipment shall be subject to the verifications established by the metrological control legislation, to verify that their metrological characteristics are maintained within the levels of established accuracy and reliability.

The operator of the measurement installation must have the corresponding telemedida equipment when its level of consumption or characteristics of the network to which it is connected makes it necessary according to the legislation in force. The telemedide equipment must be compatible with the telemedide management systems of the distributor and/or carrier, thus allowing the communication for data transmission to the same.

The measurement facilities equipped with a telemedide system will allow the display of the gas delivery parameters in the field and from the telemedide manager center of the distributor and/or carrier that delivers gas to the facilities.

For the determination of the final quantities and qualities delivered, the metrological confirmation of the measuring systems or any other verification that may be agreed, the system subjects may designate their representatives. the respective companies, which will act on behalf of their respective companies and in accordance with the provisions of the System Technical Management Standards.

The affected subjects shall notify, in writing, the remaining subjects involved in the designation of their representatives or what is established in the event that the representatives are unable to fulfil their duties. System Technical Management Standards. Any change of representative must be notified to the other subjects involved in written form.

Any modification of the procedures for the calculation and control of the quantity and quality of the gas, replacement of some measurement equipment and quality of the patterns, will be agreed between the parties affected by the measure.

In the case where new procedures, standards or measuring instruments appear in the field of quantity and quality of gas, which provide greater reliability, accuracy or speed and are economically profitable, the holder of the measure installation and the rest of the parties (including the System Technical Manager) undertake to study the possibility of using these procedures, standards or measuring instruments, or to replace those already used.

In case of discrepancy, the distributor shall provide the details of the provisional allocation at the request of the marketer within three days of the day of consumption.

6.2.1.2 Definitive delivery.-To make definitive repairs on the connection points of the transport networks with the distribution networks, each user will be considered and for each distribution network a connection point with the transport network and all gas shall be assumed to be delivered to the user concerned by that point.

The cast for each user at the point of connection to the transport network will be:

In the case of marketers, it will match the sum of the measurements, or in their case estimates, made at the supply points to each of the customers to whom it supplies increased in the corresponding distribution.

In the case of consumers who supply gas to the system that supply themselves, the allocation at the point of connection with the transport network shall coincide with the measurement at the point of supply or in its case estimation, increased in the corresponding distribution mermas.

In the case of distributors connected to networks of other distributors, We will match the measurement at the point of delivery to the downstream distributor.

7.1.2 Physical Balances per Facility. -Complementarily, the operators of the gas system will have to perform physical balances of the gas transiting through their installations. They will be intended:

Ensure the correct operation of the systems.

Control and minimize the volume of the mermas associated with the corresponding operations.

The physical balances per facility will take into account the measurements made at the different points and will provide the volume of gas delivered over the month at each point of entry and exit of the facility. transport, or, where appropriate, of the distribution network, and the corresponding Higher Calorific Power, obtained from the chromatograph defined as the associated gas quality control point.

The physical balances relating to the regasification and transportation facilities will be supervised by the System Technical Manager, who will determine its scope and periodicity according to its impact on the operation of the system. System.

7.2 Daily Balance (n + 2).

7.2.1 General requirements.-The daily balance sheet shall be drawn up for each gas day, giving the users and subjects concerned before the second day of the second working day after the day of the gas day.

All communications between those and the System Technical Manager will be performed through the SL-ATR Logistic System arranged for this purpose.

The daily business balance will be performed in accordance with the following, with the best available repair information.

For each of the users (including those responsible for the tariff supply), the System Technical Manager will quantify and notify, if applicable, for each user the following ends:

Daily gas balance stored in regasification plant tanks: An LNG per facility balance, quantifying the initial and final stock in terms of energy (kWh) and volume (m3 of LNG), depending on the Available data from entries, outputs, mermas, self-consumption and exchanges between subjects, including heels.

The data for processing will be taken from the SL-ATR Logistic System and will be contributed to it by the operators of the respective facilities, establishing the corresponding Balance, according to the following expression and detail:

Ex. Inic + Entries-(Mermas + Autoconsumptions)-Outputs-Ex. End + Exchanges = 0

For these purposes, the entries shall be calculated as the sum of the amounts allocated to the respective subject at the points of entry to each installation, with the Salidas being obtained as the sum of the regasified quantities, established on the basis of the nomination made, of the quantities actually delivered in the form of LNG and the loads of ships carried out.

Final stock determines the amount of gas owned by the affected subject at 24:00 hours each day of gas in the corresponding facilities. For appropriate purposes, the final stock shall be expressed on equivalent days of contracted capacity at the appropriate facility.

Exchanges represent the positive or negative balance of the user-for-sale and stock exchanges of LNG at the plant with other users of the plant on the day analyzed.

Daily Balance of Storage Management in the Transport Pipeline Network: A Natural Gas Balance (GN) determining final stocks, quantified in terms of energy (kWh) and in days equivalent to quantities contracted, user-owned and calculated based on initial stock and the data of the inputs per installation and outputs on the transport network disaggregated by distributor group, including mermas, self-consumption, the minimum level of filling of pipelines and exchanges between subjects.

The data for processing will be taken from the SL-ATR Logistic System.

The balance sheet will be drawn up according to the following expression and detail:

Ex. Inic + Entries-(Mermas + Autoconsumptions) -Exits -Ex. End + Exchanges = 0

Entries will be calculated as the sum of the amounts allocated at points of entry to the transport network from regasification plants, storage and international connections.

The outputs will be calculated as the sum of the amounts allocated at the transport network exit points.

The resulting final stock determines the amount of gas owned by the user at 24:00 h of each gas day on the corresponding premises.

Exchanges represent the positive or negative balance of the user for buying-sell and stock exchanges of natural gas (NG) with other users of the transport system on the day analyzed.

Daily gas balance in underground storage facilities: A natural gas balance (GN) determining final stocks, quantified in terms of energy (kWh), owned by the user and calculated on the basis of initial stock and data of injections and extractions to the transport network, meriting, self-consumption and exchanges between subjects.

The data for processing will be taken from the SL-ATR Logistic System and will be contributed to it by the operators of the respective facilities, establishing the corresponding Balance, according to the following expression and detail:

Ex. Inic + Injections-(Mermas + Autoconsumptions)-Extracts-Ex. End + Exchanges = 0

The resulting final stock will determine the amount of gas owned by the user at 24:00 h of each gas day on the corresponding premises.

Exchanges represent the positive or negative balance of the user for buying-sell and stock exchanges of natural gas (GN) with other users of the storage on the day analyzed.

7.2.2 Revisions to the daily balance sheet (n + 2). -Affected subjects may request revisions to the balance sheet of each gas day.

If no objection is raised concerning the daily balance sheets issued, before five working days of their issuance, such balances shall be understood to be accepted by the user.

Case of objection to them, the review request will contain:

The Balance Concept that the user estimates in error.

Reason why, in your judgment, the error occurred.

Within two working days following the request for the review of the daily balance sheet, the System Technical Manager will respond to the review requests received. Accordingly, the balance sheet of a calendar month shall be closed on the ninth working day of the following month.

Once the final distribution is known, it will not modify the closed daily balance sheet.

7.2.3 Regulariations to the daily balance sheet for the final distribution. -Once the definitive distribution and the regularisations have been obtained for the final fixed reservations, the regularization of the daily balance sheet, which will have to be calculated, will be calculated. the difference between the final allocation of one month in respect of the provisional allocation of the same month, as well as the regularisations to previous definitive shares.

These differences shall be allocated equally in each of the calendar days following the day of the day they are communicated to the users and shall be part of the distribution for all purposes.

7.3 Detailed information for definitive repairs.

The System Technical Manager will publish in the SL-ATR (Network Third Party Access Logistic System) detailed information of definitive repairs with a breakdown by marketer, day and point of transport-distribution connection, as well as the details of the regularisations on the daily balance sheet and the month of imputation.

This information shall be published before the 20th working day of the month following the final allocation.

9. Normal system operation

9.1 General considerations about system utilization and operation.

The System Technical Manager will have the necessary operational procedures to perform the functions entrusted, based on the information provided by the subjects that make use of the system, through the Established programming, nominations and repair, as well as demand predictions. Based on this information, the System Technical Manager will prepare the following operational documents:

Supply and demand forecast for gas with annual horizon and monthly detail, breaking down the inputs and outputs of the gas to the system, operating the regasification plants and managing the storage, identifying the possible excess or gas deficit of the system and of each of the affected subjects.

This forecast will be updated as many times as the system situation requires, taking into consideration the latest information provided by the subjects.

Plan of operations with daily detail and monthly reach on the operation of all the transportation facilities gathering the information received through the programs and nominations of the carriers. It will collect at least the organization of all gas inputs to the system, gas movement in regasification and storage plants, breakdown of supplies and inventory levels, as well as system autonomy.

This plan will be updated when the system situation requires it, taking into account information about planned or scheduled maintenance that affects the capacity of the system's facilities, as well as the latest information provided by the subjects.

Additionally, the operators of the transmission and distribution networks will draw up their respective annual operating plans for the following year. This procedure shall define the performance and performance criteria for possible eventualities of the different transport and distribution networks in order to ensure that the conditions of supply are adequate.

For the above purposes, the system restrictions affecting the annual, monthly or daily operation shall be identified and communicated to the affected subjects and appropriate measures shall be taken to annul or minimise the effects of the effects of those. These restrictions will be communicated to the Ministry of Industry, Tourism and Commerce, the National Energy Commission and the Autonomous Communities affected in those cases, which, as such, will be considered by the Technical Manager of the System.

These restrictions will be determined by installation based on:

Capacity.

Usage factor.

Design conditions.

Security limits, including at least minimum level of filling and backup equipment.

Seasonality.

The System Technical Manager will publish the following aggregated information for system agents:

Actual and forecasted daily demand curves with hourly (real and planned) detail.

Level of plant utilization, including historical evolution and future forecast.

9.2 System Normal Operation.

The gas system will be understood to be in a Normal Operation situation, when the basic control variables are within the normal operating range of the system.

The basic control variables that determine the situation of the gas system are:

the demand for gas,

the available gas capacity in natural gas inputs to the system, both natural gas (NG) and liquefied natural gas (LNG),

the operation of the LNG receiving, storage and regasification plants of the gas system, and of the compression stations, the flow at the nodes of the system, and

pressures or pressure losses on pipelines and transport and distribution networks that are critical to the gas system.

The System Technical Manager will propose the operating procedure for the calculation of the allowable ranges for the values of the control variables in order to define in what level of situation the system is located in each time, for inclusion as a detail protocol to these Rules.

In normal operation of the Basic Basic and secondary transport network, the instructions and instructions provided by the Technical Manager of the System to the different subjects shall be based on the operational procedures defined in 11.1, taking into account the technical constraints and in accordance with the criteria of reliability and security of supply to be established.

Any alteration of the intended operating conditions, or in their case emergencies, may result in a review of the monthly program and, therefore, modify the operating slogans originally provided. In the event that these alterations affect any of the subjects, it will be reported as soon as possible and with due justification, seeking to minimize its effect on the supplies affected.

In order to ensure the proper functioning of the Basic and Secondary Transport Network and to monitor the day-to-day operation, the infrastructure operators and the Technical System Manager will have a communication, control, information management, and simulation tools, operating during the 24 hours of the day.

In order for the System Technical Manager to be aware at all times of the system situation, the different operators of the transport facilities will provide the physical movement parts of the system on a daily basis. Vehicle gas through its facilities the day before. Also, in order to be able to manage at all times possible situations of exceptional operation or emergency, the Technical Manager of the System must receive continuously and in real time the main parameters of all the entrances to the system, as well as the connection points between the different transport networks.

The System Technical Manager will prepare a daily operation report that will include the forecasts and uses of the regasification, storage, international connections and, in general, the operation of all the facilities of the Basic Network and of secondary transport carried out by the various operators of the Basic Network and, if necessary, giving instructions with the modifications to the operation of those facilities which consider appropriate for the smooth operation of the system. This report will be sent to the Ministry of Industry, Tourism and Trade and the National Energy Commission within a maximum of three days.

The Technical Manager of the System, in collaboration with the other involved subjects, will develop a winter performance plan in order to guarantee the supply in the face of the increase of the demand derived from the seasonality of the domestic/commercial market and sudden cold waves.

Such a plan may include among other measures:

Input capacity reserve on connections to international pipelines.

Fixing amounts of minimum security stocks to keep in liquefied natural gas tanks and underground storage.

The detail of the action plan will be approved by the Directorate General for Energy and Mines Policy and published before October 15 each year.

The Technical Manager of the System will be in charge of imparting the necessary instructions for the proper functioning of the system in Operation Normal, being able to issue the corresponding instructions for its application to the transport, distribution, marketing and consumer companies to self-supply.

Transport, distribution, marketing and qualified consumers who self-supply will be responsible for the proper execution of the instructions issued by the System Technical Manager. In the event of non-compliance with these instructions, the Technical Manager of the System will bring it to the attention of the Ministry of Industry, Tourism and Commerce and the National Energy Commission, for the corresponding allocation of responsibilities, if procedures, in accordance with the provisions of Title VI of the Hydrocarbon Sector Act.

9.3 Publication of System Normal Operation information.

The System Technical Manager shall publish, before 14:00 hours of the day following the gas day, the following aggregated gas day information:

On gas demand, in GWh/day:

Total system demand, distinguishing between demand for the regulated market and the liberalised market.

On gas stocks in the system:

Actual LNG stocks at each regasification plant at 24:00 h, in m³ and GWh/day.

Total gas stocks in underground storage.

On gas inputs to the gas system, in GWh/day:

Total entries to the system.

LNG downloads at each regasification plant.

Gas Emission from each regasification plant.

Gas inputs or outputs for each international connection, distinguishing amounts destined for international transit.

Injection/Extract of the underground storage.

Gas production for each field.

9.4 Individual imbalances.

The daily individual imbalance will occur when the user's stock, after having carried out the daily balance sheet (n + 2), is below the minimum LNG tank filling limit or the gas pipeline network. transport or where the stocks of commercial operation of the user in the network of transport pipelines exceed the useful capacity of the pipelines of the transport network.

9.5 Measures to be taken by the user in anticipation of an imbalance.

In the event that a user anticipates that they are going to enter an imbalance situation, they will use, if any, any of the following instruments:

Gas Sales Operations to other system users.

Modification of the planned schedule and nominations plan.

Exercise the interruptibility clauses with those clients with whom you have interruptible supply contracts.

Negotiate with your own customers firm, voluntary supply disruptions.

Negotiate with other users to exercise the interruptibility clauses of foreign clients.

Using the available capabilities of underground storage.

The user will inform the System Technical Manager of the measures taken, who will assess their adequacy and adequacy to the nature of the situation.

In the case of directly supplied consumers, they must regulate their consumption in order to correct their own imbalance. Where this is caused by unscheduled unavailability of an installation, the procedure set out in the NGTS dedicated to the System Exceptional Operation shall apply.

9.6 Measures to be taken against an imbalance.

When it is observed that a user is on the imbalance for having exceeded the storage capacity in the transport pipeline network, the excess will be placed in the underground storage or in the tanks. LNG until the sum of the minimum filling level of the pipelines, the storage in the useful capacity in the pipelines of the transport network and the amount stored in the underground storage and in the LNG tanks reaches two days of storage, as defined in the storage included in the transport toll and distribution, limit above which the corresponding gas excess will be applied to the corresponding underground storage tolls increased by 5%, considering the corresponding mermas and self-consumption.

When it is observed that a user is in imbalance because of his/her stock in the network of transport pipelines below the minimum filling level, the Technical Manager of the gas stock is available in the system. of the System will be communicated to the National Energy Commission for the purposes of authorization to impute to the User of the tolls, increased by 5%, considering the corresponding mermas and self-consumption, that they would have been necessary to make The gas of the said user is available after rebuilding the necessary nomination to cover this imbalance, provided that this is technically possible and that there are no restrictions on the implementation of the winter plan.

When it is observed that a user is in an imbalance because their stock in regasification plants is below the minimum fill level, the user must make a payment to the System Technical Manager to cover the value of the entire gas until the restoration of its corresponding minimum filling level, at a unit price equivalent to 150% of the "reference market" price. If, on the other hand, the liquefied natural gas (LNG) stored exceeds the contracted storage capacity plus the capacity included in the regasification toll, the corresponding tolls increased by 5%.

As a "reference market", the auction organized by the System Technical Manager, described in this section, will be taken. In the absence of quotation from the above mentioned 'market', the lower value of comparing the cost of natural gas in the 'Henry Hub' and the 'National Balancing Point' ('NBP ') will be used as the' reference market '. .

For the determination of the cost of the gas in the "Henry Hub" and in the "NBP", the average of the last seven available quotes, expressed in cent €/kWh, will be taken from the day on which the stock was incurred.

As for the determination of prices on the "Henry Hub" markets in the United States and "NBP" in the United Kingdom, the values published as closing prices by the "New York Mercantile Exchange" under the heading "Henry" will be taken. Hub Natural Gas Future "and" International Petroleum Exchange "under the heading" IPE Natural Gas Future " respectively, converted to € applying the official daily exchange rate published in the European Central Bank. In both cases for the futures contract with maturity closer to the reference day. In the event that there has been no official exchange of natural gas from the European Central Bank, the date of the previous day shall be taken.

As in the case above, the Technical Manager of the System will communicate to the National Energy Commission for the purposes of authorization to charge the User of the corresponding tolls, increased by 5%, necessary for place the natural gas at the point of consumption, after rebuilding the same user the nomination of regasification, transport and underground storage necessary to cover the imbalance.

In order to be able to have the necessary gas before possible natural gas imbalances, the Technical Manager of the System will organize a daily gas auction among the users. To this end, the System Technical Manager will ask the users for each day and in advance, binding offers for the sale of gas. Tenders may be submitted one week in advance and up to the same day of the auction, and shall include the quantity, location and price for each day n. The acceptance of the offer by the Technical Manager of the System if applicable, will be communicated on the day n + 2.

The System Technical Manager under no circumstances will be able to accept offers whose price exceeds 150% of the cost of the lower value resulting from comparing the gas costs in the "Henry Hub" and the "NBP" in the seven days prior to the day of the auction.

In the event that there is more than one offer at the same price and the volume of gas offered by them exceeds the amount needed to cover the imbalance, it will be prorated according to the volume offered.

The System Technical Manager will publish the aggregate price curve on a daily basis for the offers received for each day.

In the event that the user who has incurred gas imbalance provides gas to the system sufficient to cover the minimum fill limits plus an additional amount equivalent to the imbalance, within a period of less than two days the date on which "n + 2" is available shall be refunded to it 25% of the price of the "relevant market" as calculated above.

Balances resulting from income and payments associated with this set of operations will have the system's liquidable income consideration.

In the event that the imbalance is caused by a responsible for the supply at tariff, the cost associated with the natural gas and the associated tolls will be supported by this one. The tolls shall be calculated by imputing the tolls necessary to place the natural gas at the point of consumption, increased by 5%, after rebuilding the necessary nomination to cover the imbalance.

If measures taken by users or time constraints do not prevent the occurrence of an imbalance that prevents the maintenance of minimum guaranteed pressures or which could endanger the stability of the system, they will be adopted. the measures set out in the rules dedicated to the Exceptional Operation of the System and, where applicable, the Emergency Situation.

9.7 System Tracking.

The Monitoring Committee of the Gas System (CSSG) is created as an organ that aims to monitor the operation of the system, the coordination between the different subjects acting on it, the presentation of information on operational plans of temporary scope (winter periods) and any other topic of interest for monitoring the system.

In order to facilitate the functioning of the Monitoring Committee of the Gas System, the System Technical Manager will publish on its website at least the following information:

A monthly gas statistical bulletin, in which you will indicate the relevant aspects of the operation of the system, evolution and coverage of the demand, uses and incidents in the network of transport, use and levels of the different storage, provisioning quality, and download.

10.1 Object.

Establish the general operation, coordination and communication measures to be adopted by the System Technical Manager and which must be performed by the affected subjects to maximize the degree of coverage of the system at all times. gas demand and ensure the safety of persons and property when the gas system is in the Situation of Exceptional Operation.

10.2 Exceptional Operation Situation. General considerations.

It is defined as the Exceptional Operation Situation (SOE) where any of the parameters that define the Normal Operation are not expected to be met, but do not require the Emergency Situation declaration.

Depending on its severity, this situation is categorized into three levels: Level 0, Level 1, and Level 2.

The operation of the system in this situation will require a declaration by the Technical System Manager and its prior communication to the Ministry of Industry, Tourism and Commerce, the National Energy Commission, and all the operators and users. Where there are situations of restriction of supply to users, the Autonomous Communities concerned shall also be informed.

You must also report any changes that occur in an Exceptional Operation situation, in the event that the Normal Operation situation is returned or when the Emergency Situation is passed.

Exceptional Operation situations will normally be caused by the unavailability of gas for its supply in an area of the gas system, by the cessation or unavailability, in whole or in part, of an LNG plant, The reduction of gas supply by an international gas pipeline, due to a strong increase in consumption, due to the lack of availability of equipment in the transport network, due to the lack of raw material for the manufacture of manufactured gas by channeling or by the existence of a disturbance in the system.

The System Technical Manager is responsible for the correct application of this operating procedure, for which it will issue the instructions for the carriers and distributors of natural gas and gas. manufactured by pipeline, as well as natural gas trading companies and consumers who are directly provisioned.

The carriers and distributors will be responsible for the proper execution of the instructions issued by the Technical Manager of the Gas System, for which it may be necessary to be transmitted to the companies Natural gas marketing companies and consumers who are directly supplied by carriers and distributors.

10.3 Previous Assessment of the Exceptional Operation Situation.

Cause of the SOE.

Weather prediction, including the state of the sea.

The estimated duration of the cause of the imbalance, or if any, of port closures.

Users who are going to be affected in their operation.

The emission capacities of LNG plants and the autonomy of stocks.

The capabilities of natural gas connections from international pipelines, the emission of deposits and underground storage, as well as their stock level.

Transport and distribution limitations that generate restrictions on emission capabilities.

The determination of the peatable demand for the SOE.

Any other relevant information.

The conclusions of the ex-ante evaluation should be forwarded to the Ministry of Industry, Tourism and Trade and the National Energy Commission.

10.4 Information to be supplied to prevent and resolve Exceptional Operation Situations.

For the performance of SOE assessments and for the adoption of corrective measures, the System Technical Manager will use the information made available to them by the different operators, and will be able to obtain from these additional information that you consider necessary.

Facility holders shall forward to the System Technical Manager information on the availability and use of the discharge, storage and emission capacities of LNG in plants, underground storage, the injection and emission of the underground storage and the transport and storage capacity of the transport pipelines, as well as the planned operational restrictions. Such information shall be kept permanently up to date.

The Technical Manager of the Electrical System and the Technical Manager of the Gas System will act in coordination on the basis of the procedures that exist or develop in this respect, with the objective of guaranteeing maximum coverage of gas needs for electrical generation.

For their part, distributors and marketers must have previously identified interruptible industrial customers, classified by market, supplier and physical location, which could be affected by the corrective actions against foreseeable imbalance rates. They must also have previously identified all the consumption above 5 GWh/year corresponding to the firm industrial customers, equally classified by market, supplier and physical location. In the contracts of all interruptible customers, whether industrial or electrical power generation, both the market at tariff and the liberalised market must be given the required time of supply cutting notice in such a way that their production facilities are not damaged before the court cited as an exceptional measure.

Based on the information obtained in accordance with the provisions of the preceding paragraph, all distributors and marketers shall draw up and submit to the System Technical Manager a plan of possible interruptions of uninterruptible and firm consumption, grouped by zones or outputs of the transport network, and with information concerning the pre-notices necessary for the interruption. This information must be permanently updated.

10.5 Coordination of system operation between operators in Exceptional Operation Situations.

The System Technical Manager will coordinate an Operation Group within the Gas System Monitoring Committee.

The Operation Group will be in charge of the actions and the provision of support to the Technical Manager of the System in making the necessary decisions on the functioning of the system, according to the procedures These are the operational requirements for NGTS-9 and NGTS-10. This group will be able to form part of the users of the system as well as the General Directorate of Energy Policy and Mines of the Ministry of Industry, Tourism and Commerce, and the National Energy Commission.

To participate in the Operation Group, users and operators must appoint a representative, who must be located 24 hours a day and during all the days of the year.

The System Technical Manager will coordinate the execution of the planned daily operating procedures with all affected users and infrastructure operators and manage any deviations that occur.

10.5.1 Temporary System Technical Manager Operating Instructions.-The General Direction of Energy Policy and Mines for urgent and temporary reasons, may authorize the Technical Manager of the System to to issue operational instructions which are not included in these rules and which are intended to redirect the system to the situation of Operation Normal or to lessen the effects of an exceptional operating situation.

10.6 Level 0 Exceptional Operation Situation

It is a situation where it is anticipated that a situation of gas deficit or surplus can be reached in the system, altering or being able to alter the Normal Operation, without this implying, in principle, a situation of risk for the guarantee, security and continuity of supply on the firm market.

This situation might occur, among others, in the following cases:

Individual User Imbalance: Marketers, who are responsible for the supply at the rate, or end customers who enter gas into the system.

Lack of natural gas stocks in the LNG tanks of regasification plants, due to the closure of cargo ports and/or LNG discharge, in-facility incidents, or non-compliance with discharge programs. any cause.

Limitations of the emission of natural gas from regasification plants, natural gas connections with international pipelines, natural gas connections with deposits and/or natural gas connections with underground storage due to contingencies in facilities or the existence of a disturbance in the system.

Limitations of gas transportation or distribution due to facilities contingencies or the existence of a disturbance in the system.

Non-compliance of the trading companies, qualified consumers who self-supply or carriers, of the monthly binding supply program.

In general, any situation caused by an unforeseeable increase in domestic market demand, or by the increase in consumption not expected as firm and which, for reasons of general interest, will become necessarily attendable.

10.6.1 Measures to be taken in the Situation of Operation Exceptional Level 0. -In the event that the imbalance is caused by a marketer, the Technical Manager of the System will verify that the supply has been interrupted of customers with whom the contract has interruptible contracts, otherwise the interruption will be made.

In the event that the imbalance is caused by the responsible for the supply at the rate, the Technical Manager of the System will verify that the supply of the customers with which he has been established has proceeded. contracts interruptible at rate (group 4) and otherwise proceed to the interruption.

If such a measure is not sufficient, or the situation is caused by another reason, the following measures shall be taken without affecting the operative of other users:

Managing storage for commercial operation on the system transport pipeline network.

Modification of ship unloading.

Changing underground storage extraction/injection slogans.

Rescheduling of international pipelines and national deposits.

Any other modification in the programming of the system operation that will minimize the impact and impact of the cause of the SOE.

By their very nature, some of the measures mentioned above will be applied simultaneously and others sequentially, and must be the System Technical Manager who determines the temporal sequence of the application operation plan.

Measures concerning the operation of the system must be communicated to the affected subjects as far as possible. To this end, the Technical Manager of the System shall inform the subjects affected by the application of these instructions. It shall also inform the National Energy Commission of the existence of the operational scenario envisaged as likely and the adoption of the exceptional measures referred to in the plan of operation to the Ministry of Industry, Tourism and Trade. and to the competent public administrations.

All of the above is without prejudice to the responsibilities that may correspond to the operators of the facilities concerned or to the users to whom the Exceptional Operation Situation is attributable.

10.7 Level 1 Exceptional Operation Situation

The system will enter this situation when the measures provided in the Level 0 Exceptional Operation Situation are insufficient to redirect the situation to the Normal Operation status.

10.7.1 Measures to be taken in Level 1 Exceptional Operation Situation. -If the problem cannot be resolved with the measures set out at Level 0, the Technical Manager of the System may employ, in this order of priority, the following measures:

Apply the interruptibility to the interruptible customers of the market at tariff and those on the liberalised market who have eventually engaged in a possible interruptible toll.

Use of minimum security stocks that do not have a strategic character.

On the basis of exceptional and prior authorisation from the Directorate General for Energy and Mines Policy, extraordinary programmes for the import of natural gas, either by pipeline or by tankers (LNG), until the limits of the Spanish gas system, provided that it is justified for reasons of short-term security of supply. The purchase procedure will be concurrent if the situation so permits.

Any alteration in the order of application of the measures set out above will require the authorization of the General Directorate of Energy Policy and Mines.

In the case of cutting off interruptible supplies, it will be necessary, first of all, to determine the areas in which the supply disruption would have to be carried out, as well as to specify the amounts and, if possible, the duration of the restrictions. Where a partial interruption of interruptible customers is established, the customers to be interrupted shall be divided between the entire market, at tariff and liberalised (in the case where there is an eventual interruptible toll). In the latter case they shall be apportioned to the interruptible market for each marketer.

The System Technical Manager will provide, to the distributors, the appropriate orders for them to comply with the instructions according to the quantities of consumption affected and the physical location of the consumption. Likewise, the Technical Manager of the Gas System will be directed to the Technical Manager of the Electrical System, as provided by the coordination procedures existing between both operators, to determine the restrictions of the supplies for electricity generation.

The extent of the outages will be determined by the System Technical Manager, taking into account that if these are imbalances generated by a failure in a particular facility, the measures will, in the first place, and in it is possible for interruptible consumers of users who are using contracted or reserved capacity in the affected installation.

All of the above is without prejudice to the responsibilities that correspond to the operator or the users to whom the imbalance situation is attributable.

In the case where a consumer with interruptible supply at rate (group 4) or with an interruptible toll, defaults during the period in which the interruption has been applied, the System Technical Manager will make it known of the Ministry of Industry, Tourism and Trade and the National Energy Commission, for the corresponding allocation of responsibilities, if it were to proceed, in accordance with the provisions of Title VI of the Law of the Hydrocarbons Sector.

10.8 Level 2 Exceptional Operation Situation

The gas system will enter this state when the measures provided in the Level 0 and Level 1 Exceptional Operation Situation are insufficient to bring the situation back to the Normal Operation status.

10.8.1 Measures to be taken by the Technical Manager in Level 2 Exceptional Operation Situation. -In the event that despite having taken all the measures set at the operating levels 0 and 1 it was not possible to correct the situation and the SOE will persist in the system, the System Technical Manager will proceed to order interruptions to the firm supply, both in the liberalised market and in the market at tariff.

In the event that this situation is caused by the imbalance of a user, the Technical Manager of the System will proceed to interrupt the firm customers of that user, attending to the established priorities of supply.

The following priorities will be followed when maintaining supply:

1. Services declared essential in accordance with the provisions of Article 60 of Royal Decree 1434/2002 of 27 December on the activities of transport, distribution, marketing, supply and procedures authorisation of natural gas installations.

2. Domestic consumers.

3. Commercial consumers.

4. Industrial consumers with a firm supply, including power plants for power generation, with the possible restrictions established by the Technical Manager of the Electrical System.

In case of service restoration, the order will be the inverse of the corresponding to the supply cut.

Without prejudice to the foregoing, the System Technical Manager will in turn draw up a supply-cut priority order within the industrial consumer segment with a firm-based supply of character based on the following principles:

Minimize the economic and technical damage resulting from lack of supply.

Select consumers from a given consumption, in order to achieve the maximum degree of operability and reduce the number of affected consumers.

To ensure that the order of court in industrial consumers is staggered and that no induced cessation of activity occurs, as the chain of basic raw materials, intermediate products and final products are broken.

It will generally be the users of the gas system responsible for securing the supply and, for the liberalised market, the trading companies and the consumers that are directly provisioned.

To ensure that the equanimity is maintained between the distribution companies, marketers and consumers affected, so that the percentages of reduction to be applied in the consumptions of a firm character, are identical in conditions similar.

To act under the principles of minimum intervention and proportionality, so that the measures taken are those which, aimed at solving the situations created, produce the least distortions in the gas market. In the case of Spanish and the subjects involved in it, the maximum protection of consumers is always being considered.

The Technical Manager of the Gas System, counting on the information provided by the carriers, distributors and marketing companies, will identify and communicate the concrete actions that make it possible to reduce the flows (consumptions) that are required.

Support for the measures taken shall be obtained from the authorities concerned.

10.9 Return to Normal Operation Situation.

Once the system returns to Operation Normal, the System Technical Manager will declare it and make a full report of what happened, including its criteria for the causes that have motivated the situation, and the measures taken and the subjects affected by those measures. This report will be sent to the Ministry of Industry, Tourism and Trade and the National Energy Commission.

Similarly, after the end of the imbalance situation, the subjects whose consumption or customers have been affected (regardless of their firm or interruptible character) may raise the number of shares they consider relevant to the repair of damage caused to them or their clients by the imbalance.

NGTS-11. "System emergency situation"

11. System Emergency Situation

The gas system will be understood to be in a state of emergency when the shortage of gas supply may require the use of strategic reserves or the safety of persons, appliances or facilities or the integrity of the network.

The Emergency Situation operation shall be based on the principles set out in Article 101 of Law 34/1998 of 7 October of the Hydrocarbons Sector and as provided for in Article 40 of Royal Decree 1716/2004.

In emergency situations, the Government will establish the conditions under which the strategic reserves of natural gas may be used by the subjects required to maintain them.

In particular it will be determined:

The use of the subject's strategic reserves affected by the situation.

The use of the strategic reserves of other subjects required for their maintenance.
