Utility co-op unveils state’s largest battery storage system


In the US state of Colorado, United Power has partnered with Engie North America and Tesla for the supply and installation of a battery energy storage system in Firestone.

United Power, an electric power cooperative serving 200,000 customers, inaugurated the 4MW/16MWh battery energy storage system to ensure grid reliability during peak periods.

The battery system will store energy enough to power 600-700 homes.
The project will help United Power to save approximately $1 million in annual operational costs.

The project is believed to be the largest lithium-ion battery storage project ever built in Colorado.

Luis Felipe Birolini vice president of business development, Engie North America, said; “This has been a leading-edge project from the start, and its success is based on great collaboration with United Power and other contributors to the project.

“We believe that demand for storage projects such as this will continue to grow rapidly and that the collaborative approach taken here is a clear indication of what can be achieved.”

“ENGIE’s ability to effectively develop, construct, and integrate multiple suppliers, technologies, and systems into the project was critical for us,” said Jerry Marizza, director of new business development for United Power.
