Resolution No. 281/17 of the MEyM (former Ministry of Energy and Mining) issued on August 18, 2017 regulated the MAT ER (Term Market from Renewable Energy Sources) regime, which sets the conditions for WEM (Wholesale Electricity Market)’s large users and GUDI (Large Distribution Company Users) to meet their demand supply obligation from renewable sources through the individual purchase within the MAT ER or through self-generation from renewable sources. Furthermore, it regulates the conditions applicable to renewable power generation projects. Specifically, it created the RENPER (Registry of Renewable Electric Power Generation Projects), where such projects should be registered.

Projects destined to supply the MAT ER should not be committed under other remuneration mechanisms (e.g., the RenovAr Program). Surplus power generation exceeding commitments with MAT ER are remunerated up to 10% of the power generation at the minimum price for the applicable technology under the RenovAr Program, and the balance is sold in the spot market.

Furthermore, agreements executed under the MAT ER regime should be administered and managed in accordance with the WEM Procedures. The contractual terms —life, allocation priorities, prices and others, except for the maximum price set forth by Law No. 27,191— may be freely agreed between the parties, although the committed volumes should be limited by the renewable energy produced by the generator or supplied by other generators or suppliers with which it has MAT ER agreements in place.

Pampa registered Pampa Energía Wind Farm, also known as PEPE II and PEPE III projects with the RENPER. It also requested the corresponding dispatch priority under MEyM Resolution No. 281/17, which was granted for the total capacity of both projects. On May 10, 2019, CAMMESA granted the commissioning of PEPE II and PEPE III. The generated energy is sold under PPAs (Power Purchase Agreements) with private parties for an average term of approximately 5 years.
