(a) Use of meter. All electricity consumed or demanded by an electric customer shall be charged for by meter measurements, except where otherwise provided for by the applicable rate schedule or contract.

(b) Installation. Unless otherwise authorized by the commission, each electric utility shall provide and install and shall continue to own and maintain all meters necessary for the measurement of electric energy to its customers.

(c) Standard type. All meters shall be of a standard type that meets industry standards. Advanced meters shall meet the standards in this section and §25.130 of this title (relating to Advanced Metering). Special meters used for investigation or experimental purposes are not required to conform to these standards.

(d) Location of meters.

  (1) Meters and service switches in conjunction with the meter shall be installed in accordance with the latest revision of American National Standards Institute (ANSI), Incorporated, Standard C12 (American National Code for Electricity Metering), or other standards as may be prescribed by the commission, and will be readily accessible for reading, testing, and inspection, where such activities will cause minimum interference and inconvenience to the customer.

  (2) Customer shall provide, without cost to the electric utility, at a suitable and easily accessible location:

    (A) sufficient and proper space for installation of meters and other apparatus of electric utility;

    (B) meter board;

    (C) meter loop;

    (D) safety service switches when required; and

    (E) an adequate anchor for service drops.

  (3) All meters installed after December 21, 1999, shall be located as set forth in this section, provided that, where installations are made to replace meters removed from service, this section shall not operate to require any change in meter locations which were established prior to this date, unless the electric utility finds that the old location is no longer suitable or proper, or the customer desires that the location be changed.

  (4) Where the meter location on the customer's premises is changed at the request of the customer, or due to alterations on the customer's premises, the customer shall provide and have installed at his expense, all wiring and equipment necessary for relocating the meter.

  (5) If provisions of this section are inconsistent with §25.214 of this title (relating to Tariff for Retail Delivery Service), the provisions of the Tariff shall control this section.

(e) Accuracy requirements.

  (1) No meter that violates the test calibration limits as set by the American National Standards Institute, Incorporated, shall be placed in service or left in service. Whenever on installation, periodic, or other tests, a meter is found to violate these limits, it shall be adjusted or replaced.

  (2) Meters shall be adjusted as closely as practicable to the condition of zero error.

(f) Notwithstanding any other commission rule, as a condition of receiving electric service or electric delivery service, the customer is deemed to have consented to the provision of meter data to the customer's electric utility, its retail electric provider, and the independent organization or regional transmission organization.

(g) If provisions of this subchapter are inconsistent with §25.214 of this title, the provisions of the Tariff shall control this subchapter.
