Mexico published the results of its 2025 Private Generation Projects Call for Proposals , awarding more than 3 GW of renewable energy and 1,257.4 MW of energy storage to 14 companies. The process, led by the National Energy Commission (CNE), awarded 20 projects to private companies , although two applicants subsequently withdrew , according to the regulatory body.
The event attracted a broad base of international investors , with notable participation from energy groups in Spain, Denmark, France, Canada, and Mexico .
Among the winning bidders are Iberdrola, Idea Energía , Sunstone Power , Copenhagen Infrastructure Partners, Dhamma Energy , Revolve Renewable Power, and Gemex, among others. Sunstone Power , financed by the Danish fund Copenhagen Infrastructure Partners (CIP) , leads the list of winning bidders.
The company will develop two projects in Campeche: La Alegría (694.2 MW) and La Esperanza (350.7 MW) .
Both projects include storage systems of 313.4 MW (1280 MWh) and 156.7 MW (640 MWh) , respectively, which positions the firm as the largest awardee in both renewable generation and batteries, with more than 30% of the national total awarded in storage systems .
Among the awardees, Green Park Energy, SA de CV , a subsidiary of Iberdrola , also stands out, having received approval for two photovoltaic plants: Tecozautla (122.3 MW) in Hidalgo and El Toro (107 MW) in Guanajuato.
Both include storage: 31.3 MW and 29.7 MW , respectively.
It is worth remembering that a few months ago Cox Energy announced the purchase of Iberdrola México for 4.2 billion dollars , an operation that covers 2,600 MW of installed capacity, with 1,232 MW renewables, and a development portfolio of 12 GW, in addition to the main electricity supplier in the country with 25% market share and more than 500 large customers.
For its part, Dhamma Energy Mexico , 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 storage systems of 50.3 MW , 42.2 MW and 55 MW , respectively.
In total, they represent 459 MW of photovoltaic capacity and 147.5 MW of batteries.
Alten Energías Renovables México Once, SA de CV , was awarded and will develop the Alten Hidalgo photovoltaic park (113.3 MW) in the state of Hidalgo, with a storage system of 31.3 MW .
The company, of European origin and with a presence in Mexico for more than a decade, is thus strengthening its portfolio of solar assets in the country, betting on hybrid solutions to reinforce the stability of the grid.
Completing the group of solar project winners, Energía Solar Herrera, SA de CV will develop a 231 MW photovoltaic plant in Puebla , which will add 60.3 MW in batteries.
CGS Solarmex I, SAPI de CV will launch the CFV CGS project (108.9 MW) in Zacatecas, with 29.6 MW of storage.
Meanwhile, Global Solar America 2, SAPI de CV will execute Global Hidalgo 2 (108.7 MW), also in Hidalgo, with 28.8 MW in batteries.
In Tamaulipas, Solarig, through the trade name Tamesí Solar, will build a 122.5 MW photovoltaic plant, with 36.2 MW in storage systems.
Finally, Gemex, through its trade name Martil Solar, SA de CV, will promote the Piedras Negras project (147 MW) in Veracruz, with a 36.2 MW storage solution.
In the wind energy segment, Elecnor , through Vientos de Panabá, SA de CV , will develop the Panabá 1B park (252 MW) in Yucatán, which will include a 102.1 MW battery system.
Also in Yucatán, Eólica Dzilam will boost the Dzilam project (120 MW) with 48.6 MW in storage.
In Oaxaca, Zapoteca de Energía will build the Zapoteca power plant (200 MW) , with 69.8 MW in batteries.
From Tamaulipas, Revolve Renewable Power will develop El 24 (130.5 MW) with 54.2 MW of storage, while in Quintana Roo, the Spanish company Idea Energía , associated with Eólica del Rocío, SA de CV , will execute the hybrid Vientos del Caribe (208 MW) with 81.7 MW in batteries.
All projects have estimated start-up 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 rest will begin progressive operation from 2028, marking a new stage of renewable deployment in the country.
According to the CNE, a new call for applications is planned for January 2026 .
