The Energy Program at Enterprise Services is a national leader in developing and managing energy savings performance contracts that help reduce energy and operation costs in public facilities.

Under state law, the DES Energy Savings Performance Contracting program is designed specifically for existing public buildings in Washington. The program offers state agencies and local government entities:

  • The most cost-effective process for completing building energy upgrades
  • A means to use utility savings to pay off set project costs
  • A partnership involving the customer agency, a private Energy Service Company and the DES Energy Program
  • Contracting guidelines

How the program works

State agencies and local government entities first enter into an interagency agreement with DES, which gives the Energy Program the legal authority to provide contracting and project management services – including providing a list of DES pre-qualified Energy Service Companies.

Once a customer agency selects an Energy Service Company, DES and the company will complete a free preliminary energy audit of the customer’s building or facility to determine potential energy efficiency projects.

Roles and responsibilities

The Energy Service Company is responsible for:

  • Identifying, designing, installing, and commissioning the project
  • Providing financing options
  • Identifying utility and grant opportunities
  • Guaranteeing equipment performance
  • Guaranteeing maximum project costs
  • Guaranteeing energy savings
  • Measuring and verifying energy savings

Should an Energy Service Company fail to develop a project that meets a customer agency’s cost-effectiveness criteria, then there is no cost to the customer agency.

The DES Energy Program is responsible for:

  • Overall contracting and project management services by an experienced DES energy engineer.
  • Providing quality assurance.
  • Negotiating the project scope, costs, terms, and equipment selections.
  • Providing yearly reviews of the Energy Service Company’s measurement and verification reports for accuracy.
