ESC and NASEO Release State GESPC Program and Project Principles

November 26, 2018

ESC and the National Association of State Energy Officials (NASEO) have released a set of principles to help strengthen and expand the use of Guaranteed Energy Savings Performance Contracts (GESPCs) to cost-effectively upgrade the performance and energy efficiency of state, local, and institutional buildings and facilities.

Having delivered over $50 billion of cost-effective energy-related upgrades over the last 30 years, GESPC has been the largest and most successful form of public-private partnership in the United States. An estimated $300 billion market remains for employing GESPC to address deferred maintenance, modernize facilities and infrastructure, achieve resource and operational savings, and improve building performance.

The new NASEO-ESC Principles seek to strengthen the quality and performance of GESPC projects, and thus increase confidence in GESPC, by improving understanding and clarifying the roles and responsibilities of customers and the energy service companies (ESCOs) that construct the projects. The Principles emphasize the use of guidelines, standardized documents and methods, technical assistance, good measurement and verification of energy savings, and robust management and tracking practices.
