Tamesí Solar project to connect to the National Electric System
By Global Infrastructure Sherpa · Feb 26, 2026
Solarig México's Tamesí Solar project, with a maximum power of 496.40 MWp, will inject its production into the National Electric System (SEN) through its own interconnection infrastructure, connecting to the SEN operated by the Comisión Federal de Electricidad (CFE). The project includes the installation of 763,705 monofacial photovoltaic modules and a 115 kV transmission line.
Deal Analysis
Solarig México's Tamesí Solar project represents a significant investment in renewable energy infrastructure within Mexico. The project, boasting a maximum power of 496.40 MWp, will directly contribute to the National Electric System (SEN) via a dedicated 115 kV transmission line. This direct injection into the SEN, operated by the Comisión Federal de Electricidad (CFE), underscores the project's importance in bolstering Mexico's electricity grid and diversifying its energy sources. The installation of 763,705 monofacial photovoltaic modules highlights the scale of the undertaking.
This development is notable due to its substantial capacity and the involvement of CFE as the offtaker, ensuring a stable market for the generated power. The project's announcement in 2026 signals a long-term commitment to solar energy within Mexico. While the project value remains undisclosed, the scale of the infrastructure suggests a considerable capital investment. This project aligns with global trends towards renewable energy adoption and contributes to Mexico's efforts to reduce its reliance on fossil fuels.
