OCI ENERGY AND CPS ENERGY BREAK GROUND ON ALAMO CITY BATTERY ENERGY STORAGE PROJECT by Sydney Colwell

One of the largest standalone energy storage projects in the region, Alamo City BESS will bring flexible power and long‑term energy resilience to the San Antonio area

SAN ANTONIO, TX (MAY 19, 2026) – Today, OCI Energy, CPS Energy, and their project teams gathered in southeastern Bexar County to mark the official start of construction on the Alamo City Battery Energy Storage System (BESS).

The ceremonial groundbreaking commemorated the transition from development to the build phase of one of the largest standalone battery energy storage projects in the region. The project is designed to strengthen how the San Antonio community is served during periods of highest electricity use.

Once completed, the 120 MW / 480 MWh facility will be capable of powering approximately 30,000 homes for up to four hours, delivering critical support during periods of peak demand. By shifting how and when electricity is supplied, the project is designed to help deliver power more efficiently and economically.

“This project represents a significant step forward toward realizing a more resilient, reliable energy system that San Antonians can be truly proud of,” said Sabah Bayatli, President, OCI Energy. “This groundbreaking reflects years of thoughtful coordination, planning, and hard work – and once completed, it will help the electric system better manage peak demand events.”

OCI Energy developed and financed the Alamo City BESS and will retain ownership under a long‑term storage capacity agreement with CPS Energy, who will have operational control of the facility to serve the San Antonio region when needed.

“Energy storage is a critical component of how we prepare for the future,” said Rudy D. Garza, President & CEO of CPS Energy. “Projects like Alamo City BESS give us the flexibility to meet growing demand, integrate more diverse energy resources, and ensure our community has reliable power when it matters most.”

Organizations with deep experience across the energy sector are supporting the delivery of this project. ING is providing construction financing, LG Energy Solution Vertech is supplying the battery energy storage technology, and Elgin Power Solutions is serving as the Engineering, Procurement, and Construction contractor.

This collaboration represents a significant investment in the region and a shared commitment to building durable infrastructure that supports Texas’ energy system during periods of high demand.

“Breaking ground on Alamo City BESS marks an important milestone in turning plans into real, resilient infrastructure for the San Antonio region,” said Sven Wellock, Head of Renewables and Power,

Americas, ING. “Battery storage plays a critical role in strengthening grid reliability during periods of peak demand, and we are pleased to support OCI Energy and CPS Energy in delivering a project that combines scale, flexibility, and long-term value for the community.”

“We’re proud to support the Alamo City energy storage project and to see construction begin,” said Jaehong Park, CEO and President of LG Energy Solution Vertech. “This project adds further resiliency and stability to the grid, leveraging energy storage to ease demand constraints and improve energy availability.”

“Alamo City BESS represents the kind of forward-looking infrastructure investment needed to support a more reliable and flexible electric grid,” said Austin Hall, President, Elgin Power Solutions. “Our team is excited to help deliver a project that will provide long-term value to the San Antonio region and support energy resilience for years to come.”

Alamo City BESS is expected to enter commercial operation in 2027.

CPS ENERGY AND ASHTROM RENEWABLE ENERGY BREAK GROUND ON SOLAR FARM by Milady Nazir

Ashtrom Renewable Energy, elected officials and partners celebrate groundbreaking of El Patrimonio

SAN ANTONIO, TX (MAY 12, 2026) – Ashtrom Renewable Energy leaders were joined by members of CPS Energy, SOLV Energy, and elected officials as they broke ground on El Patrimonio, a new solar facility in Bexar County.

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.

CPS ENERGY EXPANDS COMMUNITY SOLAR THROUGH NEW REQUEST FOR PROPOSAL FOR UP TO 50 MW by Sydney Colwell

Feb.4, 2026 – (SAN ANTONIO) CPS Energy is expanding its community solar program through a Request for Proposal (RFP) seeking up to 50 megawatts (MW) of community solar -enough to power approximately 10,000 homes during peak energy demand hours. The initiative supports the utility’s Sustainable Tomorrow Energy Plan (STEP) and reflects its ongoing commitment to delivering reliable, affordable, and sustainable energy for the San Antonio and surrounding areas.

Through this RFP, CPS Energy invites respondents to propose community solar projects that offer customers an alternative to installing and maintaining solar panels on their properties. The solicitation allows for a range of project approaches, with the potential for multiple awardees, and is designed to support scalable solutions that can be deployed in the near term.

CPS Energy has developed multiple paths for vendors to participate in the solicitation and is seeking proposals for the following: complete turnkey community solar programs, new innovative approaches to community solar that incorporate new technologies or program models, or solar installation-only solutions.

Selected respondents will enter into Power Purchase Agreements with CPS Energy for the sale of 100% of the electrical output. Responses are welcome from local and small businesses as well as larger industry leaders. As a community-owned utility, CPS Energy supports economic development and is encouraging broad participation in this solicitation.

Community solar programs can help expand access to renewable energy for customers who have faced traditional barriers to participation in the past, including those customers who live in apartments or rental homes.

“This RFP reflects CPS Energy’s continued focus on expanding our solar portfolio in ways that are flexible, scalable, and responsive to our community’s needs,” said Jonathan Tijerina, Vice President of Corporate Development, CPS Energy. “Community solar allows us to bring more renewable energy online while maintaining affordability and reliability for our customers.”

CPS Energy ranks first in Texas for solar power capacity. Through STEP, the utility is focused on reducing barriers to solar participation while supporting a diverse and resilient generation mix.

The following are key dates for the RFP:

All participants can view the RFP and must submit proposals through cpsenergy.com/bids. After the closing date, CPS Energy will begin evaluations with a goal of making selections later this year.
