Energy Savings Performance Contracting (ESPC)

ESPC is a contracting process used to identify and install energy and utility improvements in existing facilities. The process provides:

  • The most cost effective method for completing building energy upgrades and retrofits.
  • Risk management through guaranteed total project costs, equipment performance, and energy savings.

As a national leader, the Washington State Energy Program has completed over $1.6 billion dollars in performance contracts, and has satisfied over 400 state public facility customers since 1985.
