Guaranteed Energy Services Agreement

The Guaranteed Energy Services Agreement is an agreement between an Energy Service Company (NORESCO) and the County, whereby NORESCO guarantees a predetermined amount of energy savings. The GESA provides a mechanism for Allegheny County to fund capital improvements from savings realized from Energy Conservation Measures (ECMs).

Allegheny County’s Guaranteed Energy Services Agreement (GESA) provides installation of energy efficiencies with little or no up-front capital, which reduces costs and increases building performance, all with desirable social, financial, community, and environmental benefits.
