Aggreko, the world’s leading provider of mobile and modular power solutions, completed the installation and commissioning of Pedernales Electric Cooperative’s first-ever battery energy storage system: a 2.25 MW / 4.5 MWh project in Johnson City, Texas.

The battery system is connected to the grid via Aggreko’s proprietary power electronic converters and is managed by the company’s intelligent software and controls system to provide market-based regulation services to Texas grid operator ERCOT. PEC, the largest electric cooperative in the U.S., will assess the results of this installation to determine the potential for additional battery installations.

“We are pleased to work with PEC and successfully deploy this modular and scalable battery system,” said Sriram Sarma Emani, vice president of operations at Aggreko Microgrid and Storage Solutions. “This represents one of a wide range of renewable energy-related solutions that Aggreko offers, from hybrid microgrids to solar-plus-storage packages to large-scale grid emulation services for solar and wind farm commissioning. Having completed a number of storage, microgrid and renewables projects in the ERCOT market, we are proud to add this system to our portfolio of energy services within the U.S.”

"Aggreko’s technology will assist PEC in the management of the statewide grid, while providing our customers with a more reliable and affordable source of energy,” said PEC CEO Julie Parsley.

While this energy storage system is the first for Aggreko with an electric cooperative in the dynamic Texas energy storage market, this is Aggreko’s sixth battery project in the state of Texas. Those systems include the 36 MW Notrees project, North America’s largest wind-integrated battery plant. The company also offers a wide range of mobile and modular systems, including battery plants, for temporary power or energy services on an as-a-service basis.

Founded in 1938 by then-Congressman Lyndon B. Johnson, PEC is a member-owned electric cooperative serving more than 320,000 accounts across Central Texas. Aggreko is a world-leading provider of mobile modular power, temperature control and energy services. 

Aggreko is No. 10 on the RER 100.
