Founded in 1983, the National Association of Energy Service Companies (NAESCO) was established to provide a unified voice for the emerging energy savings performance contracting (ESPC) industry and to educate the market about the value of performance-based energy solutions. In its early years, the association focused on industry education, advocacy, conferences, and helping develop legislative language that supported the growth of ESPCs.
Throughout the 1990s and early 2000s, NAESCO experienced significant growth by strengthening relationships with federal agencies, state energy organizations, international partners, and research institutions. The association played a key role in advancing industry best practices, supporting policy development, expanding global collaboration, and contributing to foundational resources such as ESPC data collection, accreditation programs, and measurement and verification (M&V) protocols that helped standardize the industry.
Today, NAESCO consists of 200 member organizations, which include energy service companies, affiliates, industry partners, and public sector agencies, and continues to build upon the progress that has been made over the past forty-plus years.
Our mission is to advance the modernization of America's energy and building infrastructure by supporting our Members and Trusted Partners' ability to develop and grow their business, enabling them to deliver reliable, resilient, and cost-effective projects that reduce taxpayer burden and strengthen economic and operational efficiency. We do this by advocating for effective policies and providing our members with training, education, networking, and communication.
As the national trade association of the ESCO Community, NAESCO provides support through:
Advocacy - finding pathways to make business happen, and to solve problems that arise.
Engagement - actively involving ourselves in the energy community to encourage cost-effective solutions to infrastructure improvement.
Training - providing workshops, webinars and conferences that will educate providers and users of energy services.
Support - developing solutions to direct problems that arise on projects and issues our membership encounters.
