Success story
Energía Sierra Juárez Phase 2

Energía Sierra Juárez (ESJ) is a wind farm located in the Sierra
Juárez mountain range in Tecate, Baja California. As the first
ever cross-border wind power project between Mexico and the
U.S., it is a remarkable achievement.

The original ESJ facility has 47 wind turbines that can generate up to 155 MW of power3. When the expansion of this facility to an additional 108 MW through 26 new wind turbines was suggested, a project we call ESJ Phase 2, no one foresaw the changes in the world that would arise.

Just as the notice to proceed was issued in February 2020, the COVID-19 pandemic struck. Already under construction at the time, we continued working on ESJ Phase 2 while implementing measures to protect the health and safety of our employees and contractors.

We worked in collaboration with the National Institute of Anthropology and History (INAH) in Baja California, to modify the project layout to safeguard the archaeological heritage adjacent to El Vallecito, the only archaeological zone in the state. These efforts resulted in the discovery and protection of new Yuman archaeological remains dating from 700 to 1800 AD. Our alliance and support to INAH Baja California is expected to carry on - as that organization continues working on the analysis and recognition of the El Vallecito area. We are simultaneously rehabilitating the access road and building sanitary facilities for the public to visit this archaeological site.

ESJ Phase 2 commenced its commercial operation in January 2022 as scheduled thanks to the combined efforts and outstanding commitment of everyone involved.

With a US$150 million investment, this project increases the ESJ original capacity by 70%, which helps efforts to further develop North America’s energy markets integration.

ESJ holds lease agreements with landowners who continue receiving payments based on the company’s revenue from electricity sales, as well as other important social investment plans as part of Sempra Infrastructure’s commitment to the communities where we operate.

We view this project as an example of our commitment to building world-class and sustainable infrastructures, to usher in a new era of cleaner energy in North America and the world, and to create more job opportunities while supporting the communities surrounding our projects through agreements and extensive social investment. All this fosters the continued integration of the North American energy markets.
