Construction of the El Patrimonio Project began in 2025 and is expected to be completed in 2027. Once operational, the project is projected to supply electricity to approximately 37,000 households and reduce carbon emissions by about 193 tons annually.

“This is an exciting day for Ashtrom Renewable Energy and a major milestone in our continued commitment to delivering sustainable, reliable energy solutions,” said Yitsik Mermelstein, CEO of Ashtrom Renewable Energy.  “We want to thank our partners, including CPS Energy, SOLV Energy, Bexar County, and the City of San Antonio for their collaboration, vision and support bringing this project to life.”

“CPS Energy is the number one buyer of solar energy in Texas,” said Frank Almaraz, Chief Operating Officer of CPS Energy.  “Today’s groundbreaking and partnership with Ashtrom helps maintain our leadership position. Renewable energy is also a key part of delivering on our diverse generation plan to meet our growing population’s needs.”

“Breaking ground on El Patrimonio marks the start of an important partnership between SOLV Energy and Ashtrom Renewable Energy,” said George Hershman, CEO of SOLV Energy. “From construction through operations, SOLV is committed to delivering this project safely, efficiently, and with a focus on long term performance – supporting Ashtrom’s vision and Texas’ growing energy needs.”

Under a 20-year Power Purchase Agreement with CPS Energy, the municipally-owned electric and gas utility of San Antonio, CPS Energy will purchase about 70% of the electricity generated by the project, along with renewable energy credits. The remaining electricity will be offered in the Texas open electricity market by Ashtrom.
