Normalization of the Wholesale Electricity Market
On January 29, 2025, CAMMESA published on its website complementary information to Resolution 21/2025 of the Secretary of Energy (“SE”) (the “Resolution 21”) (Available comments on this regulation here).
Among the published documentation, there is a note sent by the SE to CAMMESA (the “SE Note”) outlining the need for gradual normalization to encourage investment and reliability of the Wholesale Electricity Market (“WEM”).
Attached to the SE Note are the Guidelines for the Normalization of the WEM and its Progressive Adaptation (the “Guidelines”) prepared by the SE, which detail the modifications in fuel management, demand in the WEM, determination of prices and operation of both the Corporate PPA Market (“MAT”) and the Spot Market.
Additionally, the SE enclosed a Technical Report on the WEM situation (the “Technical Report”). This Technical Report analyzes regulatory and operational aspects to meet regulatory objectives, focusing on system transparency and efficiency, decentralization of CAMMESA, energy prices, fuel management review, Spot Market and MAT mechanisms adaptation, and infrastructure planning.
Associations represented in CAMMESA have thirty (30) days from January 30, 2025, to provide non-binding opinions on these documents for the WEM normalization process. At the same time, CAMMESA will have forty-five (45) days to prepare: a) a detailed report with a dispatch and transactional management plan; b) an analysis of the impact of the measures on the supply and demand of the WEM, and c) a report on the considerations of the WEM Associations.
Finally, the SE announced the issuance of new regulations for the normalization of the WEM to be effective as of November 1, 2025, regardless of the possible anticipated measures to eliminate restrictions.

Deregulation of Electric and Hybrid Electric Vehicles Charging Activity
On January 29, 2025, the Secretary of Energy published Resolution 22/2025, abrogating Resolution 817/2023 (the “Resolution 817”).
Resolution 817 had created the National Registry of Charging Infrastructure for Electric Vehicles (“EV”) and Hybrid Electric Vehicles (“HEV”) and imposed the obligation to charge such vehicles exclusively at service stations.
In line with the state reorganization principles set forth in the Foundations Law the elimination of Resolution 817 deregulates the EV and HEV charging activity, allowing any establishment to provide such services.

New measures for the normalization of the Electricity Market
On January 28, 2025, the Secretary of Energy published Resolution 21/2025 (“Resolution 21”), which introduces the following key changes in the wholesale electricity market:
- Corporate PPA Market: Partially reinstates the Corporate PPA Market (“MAT”, or Mercado a Término) for thermal, hydroelectric and nuclear power plants with commercial date achieved after January 1st, 2025.
- Fuel management for Thermal Generators: As of March 1st, 2025, thermal generators operating in the Spot market (those without a PPA) will be allowed to manage their own fuel. The costs will be valued based on the reference price according to the variable production costs submitted, including transport and distribution costs, taxes and associated fees. CAMMESA will remain as the last-resort supplier, as well as the supplier of fuel for thermal generation PPAs.
- Phasing out the “Energy Plus” Regime: As of October 31st, 2025, the “Energy Plus” regime will be abrogated, although existing contracts will remain valid until their specified termination dates.
Resolution 21 is an initial but significant step in the National Government’s ongoing efforts to normalize the wholesale electricity market in a direction that fosters competition and private investment. As a result, additional and supplementary regulations are expected to be adopted in the short to medium term.
