Mexico has published the results of the 2025 Private Power Generation Projects Call, awarding more than 3 GW of renewable energy capacity and 1,257.4 MW of battery energy storage systems (BESS) to 14 companies.
The process, led by the Comisión Nacional de Energía (CNE), awarded 20 projects to private developers. However, according to the regulator, two applicants later withdrew, slightly reducing the final portfolio.
The call attracted a broad base of international investors, with strong participation from energy groups based in Spain, Denmark, France, Canada and Mexico. Among the awardees are Iberdrola, Idea Energía, Sunstone Power, Copenhagen Infrastructure Partners, Dhamma Energy, Revolve Renewable Power and Gemex, among others.
Sunstone Power, backed by Danish fund Copenhagen Infrastructure Partners (CIP), emerged as the largest awardee. The company will develop two projects in the state of Campeche: La Alegría (694.2 MW) and La Esperanza (350.7 MW). Both projects include battery energy storage systems of 313.4 MW (1,280 MWh) and 156.7 MW (640 MWh), respectively. These awards position Sunstone Power as the leading developer in both renewable generation and battery storage, with more than 30% of the total storage capacity awarded nationwide.
Another major awardee is Green Park Energy, S.A. de C.V., a subsidiary of Iberdrola, which received approval for two photovoltaic plants: Tecozautla (122.3 MW) in the state of Hidalgo and El Toro (107 MW) in Guanajuato. Both projects include battery storage systems of 31.3 MW and 29.7 MW, respectively.
It is worth recalling that a few months ago, Cox Energy announced the acquisition of Iberdrola México for USD 4.2 billion, a transaction covering 2.6 GW of installed capacity, including 1,232 MW of renewable energy, as well as a 12 GW development pipeline. The deal also includes one of the country’s leading electricity suppliers, with a 25% market share and more than 500 large corporate clients.
For its part, Dhamma Energy México, part of the DH2 Energy group, was awarded three solar projects in Hidalgo: Saturno Solar (155.7 MW), Akuwa Solar (130.8 MW) and Delfín Solar (172.8 MW). These projects include battery systems of 50.3 MW, 42.2 MW and 55 MW, respectively, totalling 459 MW of solar PV capacity and 147.5 MW of storage.
Alten Energías Renovables México Once, S.A. de C.V. was also awarded and will develop the Alten Hidalgo photovoltaic plant (113.3 MW) in the state of Hidalgo, including a 31.3 MW battery system. The European-origin company, present in Mexico for more than a decade, continues to expand its solar portfolio in the country through hybrid projects aimed at reinforcing grid stability.
Completing the solar awardees, Energía Solar Herrera, S.A. de C.V., will develop a 231 MW photovoltaic plant in Puebla, including 60.3 MW of battery storage. CGS Solarmex I, S.A.P.I. de C.V., will develop the CFV CGS project (108.9 MW) in Zacatecas, with 29.6 MW of storage, while Global Solar America 2, S.A.P.I. de C.V., will execute Global Hidalgo 2 (108.7 MW) in Hidalgo, with 28.8 MW in batteries. In Tamaulipas, Solarig, through the project name Tamesí Solar, will build a 122.5 MW solar plant with 36.2 MW of storage.
Finally, Gemex, through Martil Solar, S.A. de C.V., will develop the Piedras Negras project (147 MW) in Veracruz, including 36.2 MW of battery storage.
In the wind segment, Elecnor, through Vientos de Panabá, S.A. de C.V., will develop the Panabá 1B wind farm (252 MW) in Yucatán, including a 102.1 MW battery system. Also in Yucatán, Eólica Dzilam will develop the Dzilam project (120 MW) with 48.6 MW of storage.
In Oaxaca, Zapoteca de Energía will build the Zapoteca wind power plant (200 MW), including 69.8 MW of batteries. From Tamaulipas, Revolve Renewable Power will develop El 24 (130.5 MW) with 54.2 MW of storage, while in Quintana Roo, Spanish developer Idea Energía, in partnership with Eólica del Rocío, S.A. de C.V., will execute the Vientos del Caribe hybrid project (208 MW) with 81.7 MW in battery storage.
All projects have expected commercial operation dates between 2027 and 2029, although three projects stand out for their planned start-up in December 2027: Central Energía Solar Herrera (231 MW) in Puebla, FV Tecozautla (122.3 MW) in Hidalgo and El Toro (107 MW) in Guanajuato. The remaining projects are expected to come online progressively from 2028 onwards, marking a new phase in Mexico’s renewable energy deployment. According to the CNE, a new call is scheduled for January 2026.
