Whitepaper: Heating Emergency Power Systems with Heat Pumps
Jul 29, 2025
Standby generators are an untapped source for energy efficiency. Retrofitting a high efficiency heat pump to the existing engine heating infrastructure of a genset can reduce the energy draw needed to maintain startability of the system by up to 65%. This whitepaper, authored by Levi Westra, Principal Energy Efficiency Engineer of Avista Utilites, details the energy and cost savings achieved at five pilot sites in Spokane, WA that were retrofit with an energy efficient heat pump to become the primary source of engine heat. Download the paper today to learn more on how data centers, hospitals, and other critical facilities can benefit from Hotstart high efficiency heat pumps installed in their standby generators.
