IHI Power Services Corp. (IPSC) and its predecessors have over 30 years of experience in the operation of power generation plants (combined cycle, simple cycle, biomass, solar, wind, etc.). Previously, IPSC was known as Constellation Operating Services, Inc. (COSI). In August 2012, IHI Inc. acquired COSI to become what it is known today, IHI Power Services Corporation.

IPSC provides operations and maintenance services to over 13.5 GW of generation throughout the United States. In partnership with our sister company, IHI Power Generation Corp., we understand both the business and technical concerns of owning, operating, and maintaining power plants. We manage our customers' facilities with this generator owner and operator perspective and passion to maximize the assets investment value and reduce risk.
