Energy on Tribal Terms. By Tribes. For Tribes.
NESCO is a Native American, woman combat veteran-owned Energy Services Company helping Tribal Nations, schools, municipalities, and public agencies reduce energy costs, strengthen resilience, and maintain local control over critical energy infrastructure. For more than 17 years, we have successfully delivered Tribal, federal, educational, municipal, and community energy projects throughout California, including major initiatives with agencies in San Diego, Los Angeles, and LA Metro’s preparations for the 2028 Olympic Games.
Empowering Tribal communities to own their energy future
As a leading Native-Owned Energy Savings Company, we specialize in feasibility studies, project design, best-fit technology, innovative financing, and full EPC capabilities — all with one objective: helping Tribal governments and enterprises significantly reduce energy usage, lower utility bills, advance economic and workforce development, and build a greener, more secure community future.
Our mission is to empower Tribal clients to overcome internal capacity limits with the knowledge, tools, and expertise to optimize their unique energy, environmental, resiliency, economic, and sovereignty goals.
