Pedernales Electric Cooperative to use large battery for grid balancing

Aggreko said this week that it has completed the installation and commissioning of Pedernales Electric Cooperative’s (PEC) 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 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 plans to assess the results of this installation to determine the potential for additional battery installations, said the company.  

“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 C. 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.
