Ashtrom Renewable Energy (an independent power producer) has celebrated the groundbreaking of El Patrimonio, a new solar facility in Bexar County near San Antonio, marking a significant step in the company's expansion of clean energy infrastructure across the United States. The ceremony brought together leaders from Ashtrom Renewable Energy, CPS Energy (an Electric utility), the construction firm SOLV Energy, and elected officials.

Project Timeline and Capacity

Construction on the El Patrimonio Project began in 2025 and is expected to reach completion in 2027. Once operational, the facility is projected to supply electricity to approximately 37,000 households in the region. The project is also anticipated to reduce carbon emissions by about 193 tons annually, according to figures provided by Ashtrom Renewable Energy.

The groundbreaking ceremony marks a formal public milestone in a development process that has already been underway for roughly a year, with the project now advancing toward full construction and eventual commissioning within the Texas energy market.

Power Purchase Agreement with CPS Energy

At the center of the El Patrimonio project is a 20-year Power Purchase Agreement between Ashtrom Renewable Energy and CPS Energy, the municipally-owned electric and gas utility serving San Antonio.

Under the terms of that agreement, CPS Energy will purchase approximately 70 percent of the electricity generated by the facility, along with renewable energy credits associated with that output. The remaining 30 percent of electricity produced by the project will be offered by Ashtrom directly into the Texas open electricity market.

CPS Energy serves approximately 970,000 electric customers and 390,000 natural gas customers in San Antonio and portions of seven surrounding counties. The utility, which was established in 1860, is described as the nation's largest public power, natural gas, and electric company.

Frank Almaraz, Chief Operating Officer of CPS Energy, pointed to the utility's standing in the state's renewable sector as a motivating factor in the partnership. "CPS Energy is the number one buyer of solar energy in Texas," Almaraz said.

"Today's groundbreaking 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."

Partners and Construction Responsibility

SOLV Energy, a solar energy construction firm, is serving as the construction partner on the El Patrimonio project. George Hershman, CEO of SOLV Energy, described the groundbreaking as the beginning of a significant collaboration.

"Breaking ground on El Patrimonio marks the start of an important partnership between SOLV Energy and Ashtrom Renewable Energy," Hershman said. "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."

Bexar County and the City of San Antonio were also cited by Ashtrom's leadership as key partners in bringing the project to fruition. Yitsik Mermelstein, CEO of Ashtrom Renewable Energy, expressed appreciation for the collaborative effort that led to the groundbreaking event.

"This is an exciting day for Ashtrom Renewable Energy and a major milestone in our continued commitment to delivering sustainable, reliable energy solutions," Mermelstein said.

"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 in bringing this project to life."

About Ashtrom Renewable Energy

Ashtrom Renewable Energy is an independent power producer that develops, constructs, finances, and operates renewable energy projects in the United States and internationally.

The company is a subsidiary of Ashtrom Group, a publicly traded infrastructure, construction, and real estate development company listed on the Tel Aviv Stock Exchange under the ticker ASHG. Ashtrom Group has a reported 60-year legacy in the infrastructure and construction sector.

The company describes its approach to project development as hands-on and risk-informed, with an emphasis on strategic and cost-effective execution. Its leadership team is characterized as having decades of experience across the full lifecycle of renewable energy projects, from early-stage development through long-term operations.

Texas Energy Market Context

The El Patrimonio project arrives as Texas continues to experience population growth and rising electricity demand. CPS Energy's Almaraz noted that the utility's renewable energy strategy is directly tied to meeting the needs of a growing population in the San Antonio region.

The utility has generated USD 10.1 billion in revenue for the City of San Antonio since 1942, and its customers' combined energy bills are reported to rank among the lowest of the nation's 20 largest cities.

The structure of the El Patrimonio agreement, with the majority of output secured under a long-term contract with a municipally-owned utility and a portion directed to the competitive open market, reflects a financing and commercial approach common to large-scale solar developments in deregulated energy markets such as Texas.
