Consumers Energy, a large Michigan-based utility, selected Doosan GridTech to deliver one of the first battery energy storage systems for the energy provider. In turn, Doosan selected Commonwealth as its engineering partner on the project. As the Engineer-of-Record, Commonwealth provided project management, multidiscipline installation design, and construction support.
Commonwealth created the foundation and ground grid designs for the project. One-line, three-line, schematic, and other engineering drawings and calculations were provided by Commonwealth staff. Commonwealth designed the interconnection between various battery energy storage system (ESS) components – including the lithium ion battery skid, the power conversion system skid, and metering and protective relays – as well as the interconnection between the ESS and Consumers’ distribution network.
Commonwealth’s system studies experts developed a robust protection scheme, then protection coordination studies, arc flash studies, and lighting protection studies were completed for site safety. A hazard analysis report was just one of the many deliverables provided to Consumers.
The Parkview storage system was deployed at the Colony Farm substation in Kalamazoo, Michigan, with a capacity of one megawatt – enough energy to power 1,000 homes for an hour. The battery energy storage system (ESS) is controlled by Doosan’s Intelligent Controller™ (DG-IC™).
