The project will advance the energy sector's adoption of sustainable practices by establishing a new benchmark for energy storage solutions.
FREMONT, CA: “As demand for power soars and the western energy market becomes more volatile, the importance of our Reliable Energy Plan becomes even more apparent. As the reliability of the grid is called into question, AEPCO remains focused on making strategic investments to strengthen and diversify our portfolio and secure a stable and reliable energy future for our members. Developing these battery storage systems allows our members to experience the benefits of flexible, renewable energy,” says Patrick Ledger, Chief Executive Officer at AEPCO.
The battery energy storage system in Cochise, Arizona, has been successfully deployed to help supply clean, dependable power to its member cooperative, Sulphur Springs Valley Electric Cooperative (SSVEC). Arizona Electric Power Cooperative (AEPCO) is a not-for-profit, member-owned generation and transmission cooperative. It is made in cooperation with Prometheus Power (Prometheus), a national renewable energy provider, and Stem, a leader in AI-driven clean energy solutions and services.

“As the largest co-op in Arizona, SSVEC has worked diligently to diversify our energy portfolio from having over 80% coal-generated energy in 2016 to just 25% in 2023 with an estimated 18% generated from renewable sources. These efforts help ensure greater energy independence, reliability, and price stability for SSVEC members, with the overriding benefit of a cleaner environment. Working with AEPCO and Stem to ensure the successful deployment and optimization of our renewable energy assets will help SSVEC continue to honor our commitments of delivering affordable, reliable energy to our 53,000 members,” says Jason Bowling, Chief Executive Officer of SSVEC.
The project includes a 10-megawatt (MW) photovoltaic system and a 40-megawatt hour (MWh) energy storage system. Stems AI software monitors and manages the systems to optimize performance continuously. The project will help SSVEC by providing lower energy costs, increased transmission capacity availability, enhanced reliability, lower emissions, and fewer system losses. It will offer other ancillary services. As part of AEPCO's Reliable Energy Plan, three battery storage systems are presently being developed in Arizona, with this being the first.
“More than 900 electric co-ops across 48 states make up the largest electric utility network in the U.S. The segment is forecasted to be one of the fastest-growing segments of the front-of-the-meter (FTM) market through the end of this decade and is projected to represent over 20% of all future storage deployments. Stems unique combination of AI-driven software, hardware, and services is enabling enhanced value and project returns at scale for co-ops and their members. We are excited to bring our proven capabilities and market experience to AEPCO and their members,” says John Carrington, Chief Executive Officer of Stem.
