Wärtsilä, the massive marine and power plant specialist, is introducing its new modular energy storage product in a deployment that allows the city of Martinsville, Virginia to lower its power costs and stabilize the surrounding grid. An independent power producer, AEP OnSite Partners, will be the first to deploy Wärtsilä’s new storage product. The 9 MW/15.6 MWh battery energy storage system will respond to PJM market signals and reduce the city’s peak demand by about 9 MW, while saving $1 million per year in transmission and capacity costs, according to the company. The project is scheduled to be operational in the second half of 2021.
