2904.1 RECs, including Retroactive RECs, shall be created and tracked through the GATS.

2904.2 BTM generators and CREFs shall submit to GATS actual production data from a Revenue-Grade Generation Meter, or Inverter-Based Revenue-Grade Generation Measurement Equipment. The reporting shall comply with the production reporting requirements, terms of use, and the operating rules of the GATS. The RPS applicant shall provide accurate production data to GATS or risk facing the actions outlined in Subsections 2903.1 and 2903.2. BTM generators that are certified or were submitted to the Commission for certification before the effective date of this Subsection and currently use engineering-based estimates in GATS may continue using estimates to report output. A BTM generator that is currently permitted to use engineering estimates shall report actual production data from a Revenue-Grade Generation Meter or Inverter-Based Generation Measurement Equipment once a request for a change in the generation capacity of the BTM generator has been approved. For Solar Thermal Energy Systems that do not generate electricity:

1. (a) If the output is to be estimated, the Commission will provide GATS with the output in kilowatt-hour savings for the system, based on SRCC's estimated annual system performance of OG-300 certified systems; or
2. (b) If the Solar Thermal Energy System uses an energy meter that meets the performance standards established by OIML, then the solar thermal energy produced by the system shall be credited with one kilowatt hour (1 kWh) of electricity generated for each three thousand four hundred twelve British thermal units (3,412 BTUs) produced by the Solar Thermal Energy System.

2904.3 Production data from BTM generators and CREFs shall be recorded in GATS no less than semi-annually in order to be eligible for compliance. Estimated production shall not be allowed if the metering equipment fails. However, production data may be submitted after the equipment failure has been corrected and a full month of data has been accurately recorded.

2904.4 In the event of a clerical error that results in incorrect estimated or actual production data being reported, the eligibility of the RECs subject to that error is dictated by the following subsections:

1. (a) If an RPS account holder discovers a clerical error that resulted in fewer RECs recorded than was generated, and the RPS account holder wishes to

be credited the difference, the RPS account holder shall notify GATS of the error within thirty (30) days of discovering the clerical error. The RPS account holder shall copy the Commission on the notification to GATS. The Commission will then credit the difference between the number of RECs recorded and the number of RECs generated to the RPS account holder's GATS account as Retroactive RECs within thirty (30) business days of when notice was first given to the Commission. Any under-reported RECs attributable to a clerical error occurring before January 1st of the year that notice was given to the Commission will be deemed forfeited.

(b) If an RPS account holder discovers a clerical error that resulted in more RECs recorded than was generated, the RPS account holder shall notify GATS within thirty (30) days of the error being discovered. The RPS account holder shall copy the Commission on the notification to GATS. The Commission will then retire the difference between the number of RECs recorded and the number of RECs generated from the RPS account holder's GATS account within thirty (30) business days of when notice was first given to the Commission.

2904.5 REC eligibility shall be as follows:

(a) RECs shall be valid for a three-year period from the date of generation, except that SRECs produced by Solar Energy Systems which meet the requirements of D.C. Official Code Section 34-1432(e)(1) and which may, therefore, be used to meet the solar energy portion of the Tier One requirement shall be valid for a five (5)-year period from the date of generation. These SRECs shall be valid for a five (5)-year period from the date of generation provided they were generated as of or after March 22, 2019. A newly certified Renewable Generator can produce RECs starting back from January 1st of the year in which it was certified. Any RECs produced between January 1st of the certification year and the actual date of certification are deemed Retroactive RECs. Any Renewable Generator certified in January of any year can produce Retroactive RECs starting January 1st of the year before that certification.

(b) After December 31, 2028, the RECs that had been produced by generating facilities, on or before that date, that were certified as a Tier One source and located within an Adjacent PJM State on or before March 22, 2019, shall be valid for the remainder of the three (3)-year period from the date of generation. After December 31, 2024, the SRECs that had been produced by generating facilities, on or before that date, that were certified as a Tier One source and not located within the District or in locations

served by a distribution feeder serving the District shall be valid for the remainder of the five (5)-year period from the date of generation.

2904.6 A REC shall be retired after it is used to comply with any state’s Renewable Energy Portfolio requirement.
