Generating Station Meter Records. Every utility shall install such watt-hour
meters as necessary to obtain a record of output of its generating station or
stations. Every utility purchasing electrical energy shall install such meters
as necessary to furnish a proper record of its purchases, unless such
instruments are installed by the selling company.
Maintenance or Continuity of Service. (1) Each utility shall make all
reasonable efforts to prevent interruptions of service, and when such
interruptions occur shall endeavor to reestablish service with the shortest
possible delay. Whenever service is necessarily interrupted or curtailed for
the purpose of working on equipment, it shall be done at a time if practicable,
that will cause least inconvenience to customers, and those customers which may
be seriously affected shall be notified in advance, except in cases of
(2) Each utility
shall keep a record of: time of starting and shutting down the principal units
of its power station equipment and feeders for major divisions; indications of
sufficient switchboard instruments to show voltage and quantity of the load;
all interruptions to service affecting the entire distribution system of any
single community or important division of a community; and date and time of
interruption, date and time of restoring service, and when known, cause of each
complete distribution systems or portions of communities have service furnished
from unattended stations, the utility shall keep these records to the extent
practicable. The records of unattended stations shall show interruptions which
require attention to restore service, with estimated time of interruption.
Breaker or fuse operations affecting service shall also be indicated even
though duration of interruption may not be known.
Voltage and Frequency. (1) Each utility shall adopt a standard nominal voltage
or standard nominal voltages, as required by its distribution system for its
entire constant-voltage service, or for each of several districts into which
the systems may be divided, which standard voltages shall be stated in every
schedule of rates of each utility or in its terms and conditions of service.
(2) Voltage at
the customer's service entrance or connection shall be maintained as follows:
(a) For service
rendered primarily for lighting purposes, variation in voltage between 5 p.m.
and 11 p.m. shall not be more than five (5) percent plus or minus the nominal
voltage adopted, and total variation of voltage from minimum to maximum shall
not exceed six (6) percent of the nominal voltage.
(b) 1. For
service rendered primarily for power purposes, voltage variation shall not at
any time exceed ten (10) percent above or ten (10) percent below standard
2. Where a
limited amount of lighting is permitted under these contracts, the entire load
shall be considered power as far as voltage variation is concerned.
utility distribution facilities supplying customers are reasonably adequate and
of sufficient capacity to carry actual loads normally imposed, the utility may
require that starting and operating characteristics of equipment on customer
premises shall not cause an instantaneous voltage drop of more than four (4)
percent of standard voltage nor cause objectionable flicker in other customer's
supplying constant current circuits shall be adjusted to furnish as nearly as
practicable the rated current of the circuit supplied, and in no case shall the
current vary more than four (4) percent above or below the circuit rating.
(3) Each utility
supplying alternating current shall adopt a standard frequency of sixty (60)
hertz which shall be stated in the schedule of rates of each utility.
(4) A frequency
meter monitor shall be maintained for each system frequency. Accuracy of the
frequency meter shall be checked each day and frequency shall be governed
within limits as set forth in this section so that the frequency meters on the
system are correct once daily.
following shall not be considered a violation of this section: Voltage
variations in excess of those caused by operation of power apparatus on
customer premises which require large starting currents and affect only the
user of such apparatus, by action of the elements and infrequent and
unavoidable fluctuations of short duration due to system operation.
variation of voltage than specified under this section may be allowed if
service is supplied directly from a transmission line, if emergency service, or
if in a limited or extended area in which customers are widely scattered or
business done does not justify close voltage administrative regulation. In such
cases the best voltage administrative regulation shall be provided that is
practicable under the circumstances.
Voltage Surveys and Records. (1) Every utility shall have two (2) or more
portable indicating voltmeters and two (2) or more recording or graphic
voltmeters of type and capacity suited to the voltage supplied. Every utility
shall make a sufficient number of voltage surveys to indicate the service
furnished from each center of distribution. To satisfy the commission of its
compliance with voltage requirements, each utility shall keep at least one (1)
of these instruments in continuous service at some representative point on its
system. All records of the most recent voltage surveys taken within the last
three (3) calendar years shall be available for inspection by the utility's
customers and commission staff.
(2) Each graphic
recording voltmeter shall be checked with a working standard indicating
voltmeter when it is placed in operation and when it is removed, or
periodically if the instrument is in a permanent location. Notations on each
chart shall indicate beginning time and date of registration and when the chart
was removed, as well as the point where voltage was taken, and results of the
check with indicating voltmeter.
Servicing Utilization Control Equipment. (1) Utilities shall service and
maintain any equipment they use on customer's premises and shall adjust
thermostats, clocks, relays, or time switches, if such devices must be so
adjusted to provide service in accordance with their rate provisions.
switches used by the utility for controlling equipment such as water heaters
and street lights shall be of such quality that the timing mechanism may be
adjusted to be accurate within ten (10) minutes per month. Time switches used
by the utility for controlling street lighting or display lighting shall be
inspected or monitored at least once a month and, if in error, adjusted. Time
switches shall also be adjusted upon complaint if found in error or when
service interruptions cause them to be in error by one-half (1/2) hour or more.
switches and control devices used by the utility for controlling off-peak
appliances shall be inspected or monitored periodically and adjusted if in
error, and also adjusted upon complaint if found in error or whenever service
interruptions result in error of two (2) hours or more or in supplying service
to off-peak appliances during peak periods.
Measuring Customer Service. (1) All energy sold within the State of Kentucky
shall be measured by commercially acceptable measuring devices owned and
maintained by the utility, except where it is impracticable to meter loads,
such as multiple street lighting, temporary or special installations, in which
case consumption may be calculated. The utility shall meter its own electrical
energy use except when such service is for emergency or incidental lighting
such as outdoor substations, or at remote points on its transmission or distribution
lines. All other electrical quantities which the utility's tariff indicates are
to be metered shall be metered by commercially acceptable instruments owned and
maintained by the utility.
(2) The utility
shall regard each point of delivery as an independent customer and meter the
power delivered at each point. Combined meter readings shall not be taken at
separate points, nor shall energy used by more than one (1) residence or place
of business on one (1) meter be measured to obtain a lower rate.
facilities located at any point where energy may flow in either direction and
where the quantities measured are used for billing purposes shall consist of
meters equipped with ratchets or other devices to prevent reverse registration
and be so connected as to separately meter energy flow in each direction.
possible reactive meters required to meet the conditions of a given rate
schedule shall be either all ratcheted or none shall be ratcheted. Reactive
metering shall not be employed for determining average power factor for billing
purposes where energy may flow in either direction or where a customer may
generate an appreciable amount of his own requirements.
(5) Meters which
are not direct reading and those operating from instrument transformers shall
have the multiplier plainly marked on the dial of the instrument or otherwise
suitably marked and all charts taken from recording meters shall be marked with
the record date, meter number, customer and chart multiplier.
(6) The register
ratio shall be marked on all electro-mechanical meter registers. Meters already
in service may be so marked when they are tested.
watt-hour constant for the meter itself shall be placed on all watt-hour
meters. Meters already in service shall be so marked when they come to the
Service Connections. (1) The utility shall pay all costs of a service drop or
an initial connection to its line with the customer's service outlet, except
the attachment of the wire support to customer premises. When the customer's
outlet is inaccessible to the utility, or the customer desires that the service
outlet on any building be at a location other than that closest to the
utility's line, cost of such special construction as necessary shall be borne
by the customer. The utility shall furnish at its expense an amount of wire,
labor and material equivalent to that furnished for a like service connection
not requiring such special construction.
service requirements and administrative regulations shall be established by
each utility and be on file with the commission.
equipment and material furnished by the utility at its own expense shall remain
the property of the utility and may be removed by it at any reasonable time
after discontinuance of service.
Distribution Line Extensions. (1) Normal extensions. An extension of 1,000 feet
or less of single phase line shall be made by a utility to its existing
distribution line without charge for a prospective customer who shall apply for
and contract to use the service for one (1) year or more and provides guarantee
for such service. The "service drop" to customer premises from the
distribution line at the last pole shall not be included in the foregoing
measurements. This distribution line extension shall be limited to service
where installed transformer capacity does not exceed 25 KVA. Any utility which
extends service to a customer who may require polyphase service or whose
installed transformer capacity will exceed 25 KVA may require the customer to
pay in advance additional cost of construction which exceeds that for a single
phase line where the installed transformer capacity does not exceed 25 KVA.
(a) When an
extension of the utility's line to serve an applicant or group of applicants
amounts to more than 1,000 feet per customer, the utility may, if not
inconsistent with its filed tariff, require total cost of the excessive footage
over 1,000 feet per customer to be deposited with the utility by the applicant
or applicants, based on the average estimated cost per foot of the total
customer receiving service under such extension will be reimbursed under the
following plan: Each year, for a refund period of not less than ten (10) years,
the utility shall refund to the customer(s) who paid for the excessive footage
the cost of 1,000 feet of extension in place for each additional customer
connected during the year whose service line is directly connected to the extension
installed and not to extensions or laterals therefrom. Total amount refunded
shall not exceed the amount paid the utility. No refund shall be made after the
refund period ends.
additional customers connected to an extension or lateral from the distribution
line, the utility shall refund to any customer who paid for excessive footage
the cost of 1,000 feet of line less the length of the lateral or extension.
(3) An applicant
desiring an extension to a proposed real estate subdivision may be required to
pay the entire cost of the extension. Each year, for a period of not less than
ten (10) years, the utility shall refund to the applicant who paid for the
extension a sum equivalent to the cost of 1,000 feet of the extension installed
for each additional customer connected during the year. Total amount refunded
shall not exceed the amount paid to the utility. No refund shall be made after
the refund period ends.
contained herein shall be construed as to prohibit the utility from making extensions
under different arrangements if such arrangements have been approved by the
contained herein shall be construed to prohibit a utility from making at its
expense greater extensions than herein prescribed, if similar free extensions
are made to other customers under similar conditions.
complaint to and investigation by the commission, a utility may be required to
construct extensions greater than 1,000 feet upon a finding by the commission
that such extension is reasonable.
Distribution Line Extensions to Mobile Homes. (1) All extensions of up to 150
feet from the nearest distribution line shall be made without charge.
greater than 150 feet from the nearest distribution line and up to 300 feet
shall be made if the customer pays the utility a "customer advance for
construction" of fifty (50) dollars in addition to any other charges
required by the utility for all customers. This advance shall be refunded at
the end of one (1) year if service to the mobile home continues for that length
extensions greater than 300 feet and less than 1,000 feet from the nearest
distribution line, the utility may charge an advance equal to reasonable costs
incurred by it for that portion of service beyond 300 feet plus fifty (50)
dollars. Beyond 1,000 feet the extension policies set forth in Section 11 of
this administrative regulation shall apply.
(a) This advance
shall be refunded to the customer over a four (4) year period in equal amounts
for each year service is continued. The customer advance for construction of
fifty (50) dollars shall be added to the first of four (4) refunds.
(b) If service
is discontinued for a period of sixty (60) days, or the mobile home is removed
and another does not take its place within sixty (60) days, or is not replaced
by a permanent structure, the remainder of the advance shall be forfeited.
(c) No refunds
shall be made to any customer who did not make the advance originally.
(4) If a utility
implements specific requirements pertaining to mobile homes, such requirements
shall be subject to approval by the commission and comply with the provisions
of this administrative regulation.
Testing Equipment and Standards. (1) Each utility shall maintain sufficient
laboratories, meter testing shops, standards, instruments and facilities to
determine accuracy of all types of meters and measuring devices used by the
utility except as provided in 807 KAR 5:006, Section 17.
following testing equipment shall be available as minimum requirements for each
utility or agency making tests or checks for a utility pursuant to 807 KAR
5:006, Section 17(2):
(a) One (1) or
more working watt-hour standards and associated devices of capacity and voltage
range adequate to test all watt-hour meters used by the utility.
(b) One (1) or
more watt-hour standards, which shall be the utility's master watt-hour
standards, used for testing the working watt-hour standards of the utility.
These standards shall be of an approved type, shall be well compensated for
both classes of temperature errors, practically free from errors due to
ordinary voltage variations, and free from erratic registration. These master
watt-hour standards shall be of capacity and voltage range adequate to test all
working watt-hour standards at all loads and voltages at which they are used.
These standards shall be kept permanently at one place and not used for routine
indicating instruments, such as ammeters, voltmeters and watt-meters, of such
various types required to determine the quality of service to customers.
(d) A voltmeter
and ammeter, which shall be master indicating instruments, and which shall be
used for testing of working indicating and recording instruments. These
instruments shall be of an approved type and of accuracy class and range
sufficient to determine accuracy of working instruments to within five-tenths
(0.5) percent of all ranges and scale deflections at which working instruments
are used. They shall be kept permanently at one place and not used for routine
utility's master watt-hour standards shall not be in error by more than plus or
minus three-tenths (0.3) percent at 100 percent power factor, nor more than
plus or minus five-tenths (0.5) percent at fifty (50) percent power factor at
loads and voltages at which they are used, and shall not be used to check or
calibrate working standards unless the master standard has been certified as to
accuracy by the commission within the preceding twelve (12) months. Each master
watt-hour standard shall have a history card and calibration data available,
and when used to calibrate working standards, correction for any error of the
master standard shall be applied.
(4) All working
watt-hour standards when regularly used shall be compared with a master
standard at least once in every four (4) weeks. Working watt-hour standards
infrequently used shall be compared with a master standard before they are
watt-hour standards shall be adjusted, if necessary, so that their accuracy
will be within plus or minus three-tenths (0.3) percent at 100 percent power
factor and within plus or minus five-tenths (0.5) percent at fifty (50) percent
lagging power factor at all voltages and loads at which the standard may be
used. A history and calibration record shall be kept for each working watt-hour
standard showing all pertinent data and name of person performing tests.
(6) After having
adjusted working watt-hour standards to the accuracy specified above, service
measuring equipment shall be adjusted to within the accuracies required,
assuming working watt-hour standards to be 100 percent accurate.
calibration charts are attached to working watt-hour standards and the error
indicated is applied to all tests run and the accuracy on any range has not
varied more than two-tenths (0.2) percent during the past twelve (12) regular
test periods, accuracy limits may be extended to plus or minus five-tenths
(0.5) percent at 100 percent power factor and plus or minus seven-tenths (0.7)
percent at fifty (50) percent lagging power factor at all voltages and loads at
which the standard may be used.
utility's master indicating instruments shall not be in error by more than plus
or minus five-tenths (0.5) percent of indication at commonly used scale
deflections and shall not be used to check or calibrate working indicating
instruments unless the master instrument has been checked and adjusted, if
necessary, and certified as to accuracy by the commission within the preceding
twenty-four (24) months. A calibration record shall be maintained for each
(9) All working
indicating instruments shall be checked against master indicating instruments
at least once in each six (6) months. If the working instrument is found
appreciably in error at zero or in error by more than one (1) percent of
indication at commonly used scale deflections, it shall be adjusted. A
calibration record shall be maintained for each instrument showing all
pertinent data and name of person performing tests.
Check of Standards by Commission. (1) Each utility, and/or agency making tests
or checks for a utility, shall submit to the commission Meter Standards
Laboratory, its master watt-hour standard once in each year, and its master
indicating voltmeter and ammeter once in each two (2) years.
(2) At the
discretion of the commission any or all of these required tests may be made at
the utility's or agency's testing facility by means of portable transfer
standards. If the standards satisfy the requirements of the commission a
Certificate of Accuracy shall be issued by the commission's Division of
(3) Each utility
which normally checks its own master watt-hour standards and master indicating
instruments against primary standards such as precision watt-meters, volt
boxes, resistances, standard cells, potentiometers, and timing devices, shall
calibrate the master watt-hour standards and indicating instruments before they
are submitted to the commission for test, and attach to them a record of such
Testing of Metering Equipment. (1) Testing of any unit of metering equipment
shall consist of a comparison of its accuracy with a standard of known
accuracy. All metering equipment shall be in good order, and shall be adjusted
to as close to zero error as possible.
(2) No meter or
measuring device shall be deliberately set in error by any amount. Because of
unavoidable irregularities of work done on a commercial scale, some accuracy
tolerance shall be allowed. Meters shall be set as near as practicable to 100
percent accuracy but in no case shall the inaccuracy exceed one (1) percent.
Further, meters with defective parts shall be repaired regardless of their
equipment, including instrument transformers and demand meters, shall be tested
for accuracy prior to being placed in service, periodically in accordance with
the schedule below, upon complaint, when suspected of being in error, or when
removed from service for any cause.

Sample Testing of Single Phase Meters. A utility desiring to adopt a scientific
sample meter testing plan for single phase meters shall submit its application
to the commission for approval. Upon approval the sample testing plan may be
followed in lieu of the periodic test prescribed in Section 15(3) of this
administrative regulation. The plan shall include the following:
(1) Meters shall
be divided into separate groups to recognize differences in operating
characteristics due to changes in design, taking into consideration date of
manufacture and serial number.
(2) The sampling
procedure shall be based upon accepted statistical principles.
(3) The same
sampling procedure shall be applied to each group.
(4) Each utility
authorized to test meters by sample meter testing plan shall comply with the
(a) The number
of meters in addition to the sample shall be taken from those meters in each
group longest in service since last test unless a particular meter type is
known to be increasing the percentage of meters requiring test for the sample
group. In such a case where a particular meter type is increasing the
percentage of meters requiring test in any group, these meters may be selected
first regardless of test date with any additional tests as required for that
group coming from those in that group longest in service since last test. Each
year the utility shall use the following table to determine the percentage of
the total meters in each group to be tested.

that electric energy furnished by it is being used or will be used for
operating an illegal gambling device, it shall discontinue rendering electric
service to such customer, after reasonable notice to the customer. No damages,
penalty or forfeiture, civil or criminal, shall be found against any electric
utility for any act done in compliance with any such notice received from the
law enforcement agency or officer. Nothing in this section shall be deemed to
prejudice the right of any person affected thereby to secure an appropriate
judicial determination that such service should not be discontinued, or should

by KRS 278.230, any electric utility subject to commission jurisdiction shall
furnish to the commission upon request any records or information in the
possession of such electric utility that may assist in the enforcement of this
Underground Electric Distribution Systems for New Residential Customers. (1)
Purpose of rules. To formulate requirements for underground electric
distribution systems for all new customers of those systems which will insure
safe and adequate service and which will be uniformly applicable within a
utility's service area.
Applicability. New residential customers and subdivisions as defined below
after the effective date of this rule.
(3) Rights of
way and easements.
(a) The utility
shall construct, own, operate and maintain distribution lines only along
easements, public streets, roads and highways which are by legal right
accessible to the utility's equipment and which the utility has legal right to
occupy, and on public lands and private property across which rights of way and
easements satisfactory to the utility may be obtained without cost or
condemnation by the utility.
(b) Rights of
way and easements suitable to the utility for underground distribution
facilities shall be furnished by the applicant in reasonable time to meet
service requirements. The utility may require that the applicant make the area
in which underground distribution facilities are to be located accessible to
the company's equipment, remove all obstructions from such area, stake to show
property lines and final grade, perform rough grading to reasonable
approximation of final grade, and maintain clearing and grading during
construction by the utility. The utility may require that suitable land rights
be granted to it, obligating the applicant and subsequent property owners to
provide continuing access to the utility for operation, maintenance or
replacement of its facilities, and to prevent any encroachment in the utility's
easement or substantial changes in grade or elevation.
of underground distribution system within new subdivision.
appropriate contractual arrangements have been made, the utility shall install
within the subdivision an underground electric distribution system of
sufficient capacity and suitable materials which, in its judgment, will assure
that the property owners will receive safe and adequate electric service for
the foreseeable future.
required to be underground:
1. All single
phase conductors installed by the utility shall be underground. Appurtenances
such as transformers, pedestal-mounted terminals, switching equipment and meter
cabinets may be placed above ground.
2. Three (3)
phase primary mains or feeders required within a subdivision to supply local
distribution or to serve individual three (3) phase loads may be overhead
unless underground is required by governmental authority or chosen by the
applicant, in either of which case the differential cost of underground shall
be borne by the applicant.
(c) If the
applicant has complied with the requirements herein and with the utility's
specifications on file with the commission, and has given the utility not less
than 120 days written notice prior to anticipated date of completion (i.e.,
ready for occupancy) of the first building in the subdivision, the utility
shall complete installation thirty (30) days prior to estimated completion
date. (Subject to weather and ground conditions and availability of materials
and barring extraordinary or emergency circumstances beyond reasonable control
of the utility.) However, nothing in these administrative regulations shall be
interpreted to require the utility to extend service to portions of
subdivisions not under active development.
(5) Schedule of
(a) Within sixty
(60) days after the effective date of these rules, each utility shall file with
the commission a statement setting forth the utility's policy with respect to
electric underground extensions. Such policy shall provide for payment by the
applicant for the difference between the cost of providing underground
facilities and that of providing overhead facilities. The payment made by
applicant shall be expressed in terms of an amount per foot of conductor or
other appropriate measure.
utility's policy as filed with the commission shall set forth an
"estimated average cost differential," if any, between the average or
representative cost of underground distribution systems and of equivalent
overhead distribution systems within the utility's service areas. The payment
made by applicant as provided for in paragraph (a) of this subsection shall not
be more than the estimated average cost differential and shall be
supporting data used to determine estimated average cost differential shall be
concurrently filed by the utility with the commission and shall be updated
may be required to deposit the entire estimated cost of the extension. If this
is done, the amount deposited in excess of the normal charge for underground
extensions, as provided in paragraph (a) of this subsection, shall be refunded
to the applicant over a ten (10) year period as provided in Section 11 of this
agreement by both parties, if the applicant chooses to perform all necessary
trenching and backfilling in accordance with utility specifications, the
utility shall credit applicant's cost in an amount equal to the utility's cost
for trenching and backfilling.
extension from the property or boundary of the subdivision to its existing
supply facilities shall normally be made overhead, and any deposit required for
that extension is subject to refund under Section 11 of this administrative
regulation. Upon request, such extension may be made underground, if the
applicant agrees to pay the excess cost for the underground extension, which
excess cost shall be nonrefundable.
(g)1. Point of
service shall be that point where utility facilities join customer facilities,
irrespective of the location of the meter. Such point of service shall normally
be either at the property line or at the corner of the building nearest the
point at which underground systems enter the property to be served, depending
upon whether the utility or the customer owns the underground service lateral.
established utility practice dictates service termination at the customer's
property line, the utility shall credit the applicant fifty (50) dollars or the
equivalent cost of an overhead service line to the applicant's meter base, whichever
established utility practice does not dictate service termination at the
customer property line, the utility shall include in its underground plan the
furnishing, installation, ownership, and maintenance of the service lateral to
the meter base providing the applicant installs in the building adequate
electric service entrance capacity to the satisfaction of the utility to assure
that the underground service conductors will be adequate to handle present and
future load requirements of the building. In this instance the utility will
determine the size and type of service lateral conductors and appurtenances to
be used in any installation.
4. If, by mutual
agreement of the parties, service terminates at some other point on the building
or property, the applicant shall pay the full cost of any additional extension
required in excess of that provided for in paragraph (g)1, 2 and 3 of this
(h) When an
existing utility-owned supply circuit or service lateral requires replacement
or reinforcement due to added loads, etc., the utility at its expense will
replace or reinforce it.
(i) Nothing in
this administrative regulation shall be construed to prevent any utility from
assuming any part of the cost differential of providing underground
distribution systems within subdivisions, provided the utility demonstrates to
the commission that such practice will not result in increased rates to the
general body of rate payers.
(j) The utility
shall not be obligated to install any facility within a subdivision until
satisfactory arrangements for payment of charges have been completed by the
by applicant. Charges specified in these rules are based on the premise that
each applicant will cooperate with the utility in an effort to keep the cost of
construction and installation of the underground electric distribution system
as low as possible and make satisfactory arrangements for payment of the above
charges prior to installation of the facilities.
All electrical facilities shall be installed and constructed to comply with
applicable codes, rules and administrative regulations of the commission.
Deviations from Rules. In special cases for good cause shown the commission may
permit deviations from these rules. (8 Ky.R. 814; eff. 4-7-1982; Am. 16 Ky.R.
