Mexico is on track to define 6604 MW of solar and wind power through calls for private and mixed projects , within the framework of an investment program of MXN 794.109 billion (approximately USD 44171 billion) for electricity generation , which includes both renewable sources and other technologies.
The timeline could include a new opportunity for developers. According to exclusive information from Energía Estratégica , the Mexican government is looking to launch new calls for proposals during 2027 to ensure the continuity of advanced renewable energy projects that are not awarded contracts in the current processes.
The intention is that those initiatives that demonstrate a significant degree of development will have priority to participate again , once the observations or deficiencies that prevented their initial selection have been corrected.
This is an alternative that has not yet been publicly formalized, and its scope and final conditions will depend on the authorities. If implemented, it would allow projects with existing technical work, permits, or development progress to remain within the electricity expansion process, without necessarily having to start from a new portfolio.
This information is relevant in light of the deadlines announced by Luz Elena González Escobar, Mexico's Secretary of Energy , who confirmed that the immediate objective is to complete the awards during the last part of the year.
"In the next two months, before the end of this year, approximately 9,000 MW will be allocated for new power generation plants. We need this to meet our goal of reaching at least 38%," González stated.
That figure corresponds to the total additional capacity contemplated by the official planning, while 6604 MW constitute the volume of solar photovoltaic and wind power from private and mixed calls with the Federal Electricity Commission.
According to the official timeline, the country could have around 100 power plants under construction during 2027 , as part of the strategy to increase electricity production with renewable sources.
Million-dollar investment and over 6 GW up for grabs: how the market is divided
The generation program presented by the authorities mobilizes 794.109 billion pesos , equivalent to approximately USD 44.171 billion .
The distribution distinguishes three financing modalities: 452,538 million pesos in mixed projects (USD 25,172 million), 199,109 million pesos in private generation (USD 11,075 million) and 142,462 million pesos through direct investment by the Federal Electricity Commission (USD 7,924 million) .
The mixed component represents about 57% of the total investment in generation , while private initiatives account for approximately 25% and direct financing from CFE, 18%.
Furthermore, the 794.109 billion pesos cover different generation technologies, so they should not be interpreted as an investment intended solely for photovoltaic and wind farms.
To this budget are added 161,226 million pesos for transmission and 72,470 million pesos for distribution , bringing the investment specifically allocated to the electrical system to 1,027,805 million pesos , approximately USD 57,170 million.
In the renewable energy segment, the calls for proposals currently underway represent one of the main instruments to convert that financial planning into new installed capacity.
It is worth remembering that the Mexican government closed registration for both the mixed and private calls for proposals on September 2nd.
According to information gathered by Energía Estratégica , Terralia, Cox, Atlas Renewable Energy, AES, Invenergy and Copenhagen Infrastructure Partners (CIP) are participating in this new pre-selection round.
Industry sources consulted by this publication also indicate activity by Kiin Energy, Sungrow Renewables, Polaris, Atlántica, and GEMEX regarding the current bidding processes. GEMEX is among the developers expected to achieve favorable results.
The definition of the selected projects will be crucial in determining which companies will incorporate new capacity, which technologies will predominate, and how investments will be distributed among the different states.

The possibility of opening new instances in 2027 also introduces a perspective of continuity for companies that do not obtain an award at this stage, especially when projects require addressing technical or administrative observations.
In parallel, the Government confirmed progress on a renewable portfolio that already has allocations from the private call for bids in December 2025 and the first round of mixed projects with CFE.
"We have already started this process, we already have 55 projects underway through 42 photovoltaic plants that take advantage of solar radiation and 13 wind farms where CFE participates with 70% of the portfolio of these projects," González stated.
According to the government presentation, these initiatives represent approximately 10.9 GW of capacity , in different stages of development and implementation.
However, it later specifies that part of the portfolio is under construction, while another part will have to complete its corresponding permits and procedures during the coming months.
Storage, Puerto Peñasco and the challenges of renewable expansion
It is worth remembering that projects participating in the calls for proposals are required to incorporate battery energy storage systems (BESS) equivalent to 30% of the generation capacity of the power plants, with a duration of three hours .
In addition, there is an open call for bids for 935 MW of BESS capacity. Mexico's Ministry of Energy (SENER) has extended the deadline for registering BESS systems within the process to October 30, 2026 .
Regarding large solar developments, one of the central projects of the state strategy is Puerto Peñasco, in Sonora , where CFE seeks to complete one of the largest international photovoltaic complexes.
The plant will have 1000 MW of solar capacity , with its first two stages already operational and new phases planned for 2027 and 2028.
"Puerto Peñasco will become one of the five largest photovoltaic power plants in the world," said Emilia Calleja, director of CFE, referring to the projected size of the complex.
The project also incorporates transmission infrastructure intended to strengthen the supply to Baja California and improve its integration with the rest of the Mexican electrical system.
This component will be relevant to support the expansion of solar and wind power developments, since the incorporation of new generation depends on the availability of capacity to transport electricity to consumption centers.
On the other hand, CFE reported that it has 60 transmission projects underway and that the extension of its network will reach approximately 115,000 kilometers .
The company is also making progress in modernizing existing hydroelectric facilities. Between 2025 and 2026, it completed eight rehabilitation projects that added 53 MW of capacity .
Also noteworthy within the hydroelectric portfolio is Chicoasén II, in Chiapas , with a planned capacity of 240 MW , distributed across three 80 MW turbines.
The project envisions an estimated annual production of 591 GWh , by harnessing the flow of the Grijalva River, and is part of the investments aimed at extending and modernizing the country's renewable generation infrastructure.
In this way, the government strategy combines new photovoltaic and wind power plants, hydroelectric rehabilitation and expansion of the networks necessary to incorporate electricity into the national system.
The potential opening of new calls for proposals in 2027 could become a second opportunity for renewable energy projects with an advanced stage of development , although it remains to be seen whether the proposal will be formalized, what its priority criteria will be, and what additional capacity it will bring into play.
Meanwhile, the Mexican market is focusing its attention on the awarding of 6,604 MW , the progress of storage systems, and the execution of investments announced by the authorities to transform the project portfolio into new operational electrical capacity.
