Energía Sierra Juárez

Energía Sierra Juárez is the first cross-border renewable energy project between Mexico and the United States.


Tecate, Baja California


263 MW

Energía Sierra Juárez (ESJ) wind farm in Tecate, Baja California, provides 263 megawatts (MW) of zero-carbon electricity to the California electricity market.

Phase 1 of the project included 47 wind turbines of 3.3 MW each. The Phase II expansion, which began operations in the first half of 2022, added 26 new wind turbines with a total incremental capacity of 108 MW. The increased production is equivalent to the annual energy consumption of over 180,000 homes and is expected to reduce greenhouse gas emissions by nearly 170,000 tons of carbon dioxide (CO2) per year.

Energía Sierra Juárez interconnects with the Southwest Powerlink system at the East County substation of San Diego Gas and Electric (SDG&E). It could also eventually connect directly to Mexico's transmission network.
