Two additional energy storage projects are coming to Ohio, according to recent announcements, bringing the state’s total to ten. 

First, Duke Energy in partnership with LG Chem, one of the world's largest producers of advanced chemicals and materials and a leading supplier of lithium-ion batteries, and Greensmith, a supplier of energy storage control and analytics software, announced plans to develop a two megawatt (MW) battery storage project. The project will be located on the retired coal-fired W.C. Beckjord power plant site in New Richmond, which already houses 2 MW of battery capacity.

Second, Renewable Energy Systems Americas Inc. (RES) is planning the “Willey Battery Storage Project,” to be located in Hamilton.  The project will be owned by the Sumitorno Corporation. 

Both projects cite opportunities to participate in the PJM Interconnection’s (PJM) frequency regulation market as an important project location determinant.  Regulation services are necessary to provide real-time, fine-tuning for the network to match supply and demand, resulting in a constant frequency. The energy store responds to a signal provided by the market operator, PJM.  Energy storage systems can often provide frequency regulation services much more effectively than traditional power plants.  In addition to providing frequency regulation services, energy storage is able to support grid stability by storing excess energy when demand is low and supplying extra power when demand is high.
