Leeward signs 15-year deal with PG&E for 450MWh of Arizona storage

June 5, 2024

Leeward Renewable Energy has signed a 15-year long-term resource adequacy agreement with Pacific Gas & Electric Company (PG&E) for LRE’s 112.5MW /450 MWh Sierra Pinta Energy Storage project in Yuma County, Arizona.

Sierra Pinta, a standalone battery energy storage (BESS) facility, is adjacent to LRE’s 179-MW White Wing Ranch Solar project, which is currently under construction.

The project’s storage capacity is equivalent to the energy needed to power over 90,100 US. homes for four hours, according to Leeward.

Sierra Pinta Energy Storage is expected to create approximately 98 “well-paying union jobs during peak construction and generate significant property tax and economic benefits” for Yuma County, Leeward said.

Construction of Sierra Pinta Energy Storage is expected to begin in September 2024, and the project is expected to be operational in the first half of 2025.

“We are proud to partner with PG&E on this transformative project, supporting the transition to a cleaner and more reliable grid while bringing significant tax benefits to the community,” said Eran Mahrer, Leeward’s chief commercial officer. “Sierra Pinta Energy Storage expands our project footprint and further solidifies our commitment to the region. We look forward to continuing our long-term partnership with Yuma County and the local community as we develop and operate the project.”
