ANNEX I

Operation Procedure 14.12: "Estimating the cost of voluntary price components for the small consumer"

1. Object.

The purpose of this procedure is to set the method of estimating the cost of those components of the voluntary price for the small consumer (PVPC) that are not known at the time the system operator must publish them the day before the supply for 24 hours the next day.

2. Scope of application.

This procedure applies to the system operator (OS) and reference marketers (COR).

3. Publish time of the PVPC components.

Before 20h30 of each day, the system operator shall publish the values of the components necessary for the calculation of the PVPC for each of the 24 hours of the following day, according to the provisions of the present procedure.

4. Estimating the cost of PVPC components.

4.1 Average time price component estimate.

For the calculation of the average hourly price component Pmh, in addition to the results of the daily market, the marginal price and energy values married in the first session of the intraday market shall be considered.

4.2 Estimate of tuning services in hour h.

The value of the cost for the system adjustment services associated with the supply in hour h, SAh, shall be calculated in accordance with the following formula provided for in Article 11 of Royal Decree 216/2014 of 28 December 2014. March:

SAh = PMASh + CDSVh

Being:

PMASh: The time price for all system tuning services whose cost is assigned to the demand.

CDSVh: Cost of hourly deviations per MWh consumed from reference marketers.

4.2.1 Adjustment Services Time Price Estimate (PMASh).

The time price of the system tuning services whose cost is assigned to the demand will be calculated using the following formula:

PMASh = PMAS1h + PMAS2h

Being:

PMAS1h: Schedule price component of the adjustment services, PMASh, the cost of which is known before the time of publication of the PVPC the day before the supply, as determined in paragraph 3 of this procedure.

This component is the result of dividing the cost of technical constraints into the Base Operating Program (PBF), the fixed cost of the secondary throttling band, and the cost of the additional power reserve to be uploaded, between the scheduled demand on the market, with the data known at the time of the PVPC publication.

Where:

ImpPMAS1h: Amount of tuning services called and the result of which is known before the PVPC publication time the day before the supply, in euros.

DemPHF1ua, h: End time schedule of demand for the ua marketer or direct consumer programming unit in central bars, for hour h, after the first session of the intraday market, in MWh.

PMAS2h: Schedule price component of the adjustment services, PMASh, the cost of which is not known before the time of publication of the PVPC the day before the supply, as determined in paragraph 3 of this procedure.

This unknown cost includes, among others:

-variation of the cost of restrictions for unrealized starts and non-compliance with scheduled power failures;

-variable cost of the secondary regulation band in real time;

-variation of the cost of the additional power reserve to be increased by default and by allocation of part of the cost to output measured deviations;

-cost of technical constraints in real time;

-cost per system deviations;

-income/cost of the balance of deviations.

The estimate of the PMAS2h time component will be, for each of the hours of the month m, the sum of two terms:

PMAS2h = PMAS2Am + PMAS2Bm

PMAS2Am: Estimated price of the components of the adjustment services whose amount in euro is not dependent on demand and settled in the last twelve months with full month closed settlement:

-technical constraints to the PBF and in real time,

-power reserve to be uploaded,

-high school band,

-detours between systems.

5. Estimate of the loss coefficient of the access toll.

5.1 Peninsular system.

For the purpose of the application of the provisions of the fourth Royal Decree 2016/2014, the loss coefficient of the application access toll to the supply at hour h, PERDh, as defined in that royal decree, will be calculated using the following formula:

PERDh, pa, nt = KEST * CPERNpa, nt

Where:

KEST: Estimated time adjustment coefficient.

CPERNpa, nt: Loss coefficient for consumer supply points with pa access toll and nt voltage level in the tariff period corresponding to hour h.

These loss ratios shall be those set out in the relevant regulations, to transfer the energy supplied to consumers to power supplied in central bars.

The estimated one-hour KEST adjustment coefficient will be calculated as:

a) Arithmetic mean of the time adjustment coefficients K of the same time and same day of the week of the same month of the previous year with positive K value and less than 2, except in the hours of the national holidays fixed date substitutable.

(b) Arithmetic mean of the time adjustment coefficients K of the same hour and the same non-replaceable national holiday with a fixed date of the previous three years with a positive K value and less than 2 in the hours of the public holidays non-replaceable national fixed date.

c) If in one hour all the historical values of K are negative or zero, KEST will be equal to 0. If in one hour all historical values of K are greater than or equal to 2, KEST will be equal to 2. If in one hour all historical values are negative, zero, equal to 2 or greater than 2, KEST will be equal to 1.

The time adjustment coefficient K will be calculated as the one corresponding to the last available measure closure according to the following formula:
