EnergyCAP's history dates back to 1980. In response to a growing demand for energy management software when PCs were in their infancy, Steven D. Heinz founded OmniComp, Inc. in 1980 and launched the development of EnergyCAP’s predecessor FASER Energy Accounting. FASER was first commercially released in 1982 for utility bill verification, tracking and reporting, and the calculation of the cost avoidance attributable to energy management activities (also called Measurement & Verification).
FASER became widely used by retail chains, government organizations, universities, school districts, and property managers. By the mid-1990s, FASER's thousands of users tracked an estimated five million bills a year valued at $2 billion. FASER and OmniComp were purchased by Enron Corporation in 1996. Following Enron's bankruptcy in late 2001, Heinz acquired the energy information assets and launched Good Steward Software, LLC, which was incorporated and renamed EnergyCAP, Inc. in January 2010.
