Energy Savings Performance Contracting (ESPCs) enables public and institutional buildings, such as those owned by state and local agencies, municipalities, universities, schools, hospitals, wastewater treatment plants, and others, to finance the cost of energy and water improvements through the energy cost savings they achieve. To execute an ESPC, an agency contracts with an Energy Services Company (ESCO), which performs audits of the building in question, identifies potential areas for energy savings and, with the building owner’s agreement, makes the upgrades needed to achieve the level of energy savings specified in the contract. The savings on the building’s utility bills are then used to pay back the ESCO. Because the ESCO guarantees a certain level of savings, if the building does not achieve those savings, the ESCO makes up the difference in payment to the building.
In many states’ enabling legislation, the legal authority for ESPC – along with the ability to access low-cost capital for ESPC-financed projects – relies on the energy savings guarantee. The guarantee is a key component of the contract, as it provides a way for facilities to make energy improvements without having to utilize their existing budgets. However, to prove that ESPC upgrades are delivering guaranteed savings, measurement and verification (M&V) of those savings is an essential element of strong ESPC program design. Properly verifying that the agreed-upon savings are being achieved by the building owner is as important to the contract as the promise of the guarantee itself.
State Energy Offices play a critical role in the development and design of ESPC programs. Many State Energy Offices help design and run ESPC programs, prescreen ESCOs that other agencies can hire for performance contracts, provide input on the design of documentation, and help ensure that the savings guaranteed by the ESCOs are actually occurring through rigorous measurement & verification procedures. State Energy Offices also provide outreach, education, and support to local governments and other public building owners considering ESPC upgrades.

This foundational training course covered the basics of ESPC financing for energy efficiency. Focus was given to how state and local governments can facilitate these investments, and how facility managers can begin the process of enhancing their facility’s energy performance through ESPC.
- NASEO-ESC-NAESCO State ESPC Principles
NASEO, Energy Services Coalition (ESC), and National Association of Energy Service Companies (NAESCO) joined forces in establishing principles for strengthening and expanding the use of Energy Savings Performance Contracts (ESPCs) to cost-effectively upgrade the performance and energy efficiency of state, local, and institutional buildings and facilities.
- Understanding Your ESPC Savings Guarantee
This guide summarizes some of the important aspects of savings guarantees in energy savings performance contracts (ESPCs) and includes links to reference documents for readers who want more detail.
- The Business Case for Conducting Measurement and Verification in State and Local Government Energy Savings Performance Contract Projects
When effectively implemented, measurement and verification enables ESPCs to succeed by documenting the quantity of energy savings (and sometimes demand, water, O&M, and other savings) over an extended period of time. Measurement and verification tracks whether guaranteed savings have been achieved, and can identify opportunities to optimize energy savings performance, improve financial outcomes, and document other benefits.
- Energy Performance Contracting for State and Local Governments: Strategies for Successful Measurement and Verification
Energy savings performance contracts (ESPCs) enable public agencies to implement facility improvements with little or no upfront capital costs by leveraging a guaranteed multi-year stream of avoided utility and other costs. The process of measuring actual energy (and sometimes water and other non-energy) savings after project installation, known as measurement and verification (M&V), is an essential component of ESPCs.
