    Blattner Energy, a power generation contractor and leading provider of renewable energy construction in North America, announced that it has completed construction of one of the largest battery storage projects on the market today. The 20 megawatt (MW) Lee/DeKalb energy storage system in northern Illinois is now operational and provides the regional transmission organization, PJM Interconnection, the frequency regulation support needed for the area.

    Battery energy storage is an emerging technology, and Blattner Energy was chosen as the engineering, procurement and construction (EPC) contractor because of its demonstrated expertise in project management and its ability to take an emerging technology from concept to completion in a quality manner. At the Lee/DeKalb site, Blattner Energy was responsible for engineering the system, procuring the technology and equipment, the installation and interconnection of the system technology, as well as completing the testing and start-up activities. The project included the expertise of Greensmith Energy Management Systems as the integrator of eight containers, 10 feet by 40 feet in size, housing 2.5 MW of LG Chem lithium-ion batteries each – the same type of batteries currently used in some high-performance electric vehicles.

    “We are proud and excited to be working at the forefront of this growing technology,” said Stephen Jones, director of solar, Blattner Energy. “Battery storage will be a key technology in supporting the stability of our grid and the intermittency of some renewable generation sources. Our proven expertise in energy project management is why owners turn to us to manage their most forward-thinking projects and bring them online on time, efficiently and safely.”
