4901:1-10-05 Metering.

(A) Electric energy delivered to the customer shall be metered, except where it is impractical to meter the electric usage, such as in street lighting and temporary or special installations. The usage in such exceptions may be calculated or billed on a demand or connected load rate as provided in an approved tariff on file with the commission.

(B) A customer's electric usage shall be metered by commercially acceptable measuring devices that comply with "American National Standards Institute" (ANSI) standards. Meter accuracy shall comply with the 2001 ANSI C 12.1 standards. No metering device shall be placed in service or knowingly allowed to remain in service if it does not comply with these standards.

(C) Electric utility employees or authorized agents of the electric utility shall have the right of access to the electric utility's metering equipment for the purpose of reading, replacing, repairing, or testing the meter, or determining that the installation of the metering equipment is in compliance with the electric utility's requirements.

(D) Meters that are not direct reading meters shall have the multiplier plainly marked on or adjacent to the meter. All charts taken from recording meters shall be marked with the date of the record, the meter number, the customer name, and the chart multiplier. The register ratio shall be marked on all meter registers. The watt-hour constant for the meter shall be placed on all watt-hour meters.

(E) The electric utility's meters shall be installed and removed by the electric utility's personnel or authorized agent. Before initial service to a service location is energized, the electric utility shall verify that the installation of the meter base and associated equipment has either been inspected and approved by the local inspection authority or, in any area where there is no local inspection authority, has been inspected by an electrician.

(F) Metering accuracy shall be the responsibility of the electric utility.

(1) Upon request by a customer, the electric utility shall test its meter to verify its compliance with the ANSI C 12.1 standards within thirty business days after the date of the request.

(2) The customer or the customer's representative may be present when the meter test is performed at the customer's request.

(3) A written explanation of the test results shall be provided to the customer within ten business days of the completed test.

(4) If the accuracy of the meter is found to be within the tolerances specified in this rule:

(a) The first test at the customer's request shall be free of charge.

(b) The electric utility may charge the customer an approved tariffed fee for each succeeding test conducted less than thirty-six months after the last test requested by the customer. Each electric utility shall notify the customer of such charge prior to the test.

(5) If the accuracy of the meter is found to be outside the tolerances specified in this rule, the electric utility:

(a) Shall not charge a fee or recover any testing expenses from the customer.

(b) Shall recalibrate the meter or provide a properly functioning meter that complies with the ANSI C 12.1 standards without charge to the customer.

(c) Shall, within thirty days, pay or credit any overpayment to the customer, in accordance with one of the following billing adjustments:

(i) When the electric utility or customer has established the period of meter inaccuracy, the overcharge shall be computed on the basis of metered usage prior and/or subsequent to such period, consistent with the rates in effect during that period.

(ii) When the electric utility and customer cannot establish the period of meter inaccuracy, the overcharge period shall be determined to be: the period since the customer's "on" date or the period since the date of most recent meter test performed, whichever is shorter. The applicable rates shall be those in effect during the period of inaccuracy in order to determine the appropriate credit or refund.

Paragraph (F)(5) of this rule shall not apply to meter or metering inaccuracies caused by tampering with or unauthorized reconnection of the meter or metering equipment.

(G) Each electric utility shall identify, by company name and/or parent trademark name and serial or assigned meter numbers and/or letters, placed in a conspicuous position on the meter, each customer meter that it owns, operates, or maintains.

(H) Each electric utility shall maintain the following records regarding each meter that it owns, operates, or maintains, for the life of each such meter plus three years:

(1) Serial or assigned meter number.

(2) Every location where the meter has been installed and removed, together with the dates of such installations and removals.

(3) Date of any customer request for a test of the meter.

(4) Date and reason for any test of the meter.

(5) Result of any test of the meter.

(6) Meter readings before and after each test of the meter.

(7) Accuracy of the meter found during each test, "as found" and "as left".

(I) Each electric utility shall comply with the following requirements regarding meter reading:

(1) The electric utility shall obtain actual readings of all its in-service customer meters at least once each calendar year. Every billing period, the electric utility shall make reasonable attempts to obtain accurate, actual readings of the energy and demand, if applicable, delivered for the billing period, except where the customer and the electric utility have agreed to other arrangements. Meter readings taken by electronic means shall be considered actual readings.

(2) In addition to the requirements of paragraph (I)(1) of this rule, the electric utility shall provide, upon the customer's request, two actual meter readings, without charge, per calendar year. The customer may only request an actual meter read if usage has been estimated for more than two of the immediately preceding billing cycles consecutively or if the customer has reasonable grounds to believe that the meter is malfunctioning.

(3) An actual meter reading is required at the initiation and/or the termination of service, if the meter has not been read within the sixty calendar days immediately preceding initiation and/or termination of service and access to the meter is provided.

(4) If the meter has most recently been read within the thirty-three to fifty-nine calendar days immediately preceding the initiation and/or termination of service, the electric utility shall inform the customer, when the customer contacts the electric utility, of the option to have an actual meter read at no charge to the customer.

(5) If the meter has been read within the thirty-two calendar days immediately preceding the initiation and/or termination of service, the electric utility may estimate usage.
