Guaranteed Energy Savings Program (GESP)


What is Performance Contracting?

Energy Savings Performance Contracting (ESPC) is a performance-based procurement and financing mechanism that leverages maintenance, operations, and utilities savings achieved through the installation of energy efficiency and renewable energy measures, to finance the cost of the facility retrofit and renewal project, with no bonding or raising taxes.

What is the Guaranteed Energy Savings Program?

Guaranteed Energy Savings Program The Guaranteed Energy Savings Program (GESP) promotes awareness and implementation of energy efficient and renewable energy measures in public facilities to provide millions of dollars in annual energy savings in Minnesota. To do this, GESP supports you every step of the way. GESP can help you:

  • Solicit and award site-specific requests for proposals from pre-qualified Energy Service Companies (ESCOs) to perform Energy Savings Performance Contracting (ESPC) services
  • Evaluate the technical and financial feasibility of ESCO proposals
  • Negotiate and award work order contracts to pre-qualified ESCOs under the GESP Master Contract to implement energy conservation measures
  • Offer project management oversight of ESPC projects
  • Provide technical assistance to ensure the ESPC Measurement and Verification Plan is properly performed throughout the performance period of the contract

The Benefits of Bundling

GESP allows you to bundle projects so that low-hanging fruit can finance deeper retrofits without impacting your budget. Learn more about how to bundle projects, as well as the potential savings of different types of energy efficiency upgrades. Bundling projects in and between the types of facilities below is a benefit of GESP. These projects were not completed with GESP, but they provide insight into how to bundle energy conservation measures, as well as the potential costs, savings, and paybacks of upgrades, in and between multiple facilities.
