NORESCO

What NORESCO does

NORESCO is a U.S.-based energy services company (ESCO) that delivers performance-based energy efficiency, water conservation, and infrastructure modernization solutions to government, education, healthcare, and institutional customers. Founded in 1984 as a spin-off from Massachusetts Electric's energy services business and headquartered in Westborough, Massachusetts, NORESCO operates as a wholly-owned subsidiary of Carrier Global Corporation (NYSE: CARR). The company has accumulated more than $5 billion in guaranteed energy and operating cost savings across 10,000+ facilities over its 40+ year history and currently employs 501-1,000 staff.

NORESCO's core offering is centered on performance-based contracting models—primarily Energy Savings Performance Contracts (ESPC), Utility Energy Service Contracts (UESC), Design-Build-Operate-Maintain (DBOM), and Public-Private Partnerships (P3)—under which NORESCO finances projects with private capital, eliminates upfront customer costs, and is compensated based on verified savings outcomes. Technical capabilities include building automation and energy management systems, microgrids with islanding capability, cybersecure facility controls aligned to NIST Risk Management Framework, renewable energy integration, water conservation systems, and proprietary compliance software (CBECC/CBECC-Res supporting California Title 24 verification). NAESCO accreditation has been held continuously since 1996, and NORESCO is ranked #1 among 20 ESCOs under the DOE ESPC IDIQ.

Revenue is generated through multi-year and multi-decade performance contracts with federal agencies (EPA, FBI, Navy, Marine Corps, Army), state and local governments, K-12 districts, higher education institutions, healthcare facilities, corrections facilities, and water/wastewater utilities. Distribution is exclusively direct enterprise sales via approved government procurement vehicles (DOE ESPC IDIQ, UESC arrangements, state-approved contracts), supplemented by channel partnerships with regulated utilities such as Dominion Energy. Pricing is custom-engineered on a project basis and not publicly disclosed.

Revenue model

1. Energy Savings Performance Contracts (ESPCs): NORESCO's primary revenue stream is through Energy Savings Performance Contracts, where the company's compensation is tied directly to verified energy and operational cost savings achieved. Projects require no upfront capital from the customer. NORESCO designs, engineers, constructs, operates, and maintains facilities while guaranteeing savings outcomes.
2. Utility Energy Service Contracts (UESCs): Contracts with regulated utilities to implement energy efficiency upgrades on the utility's behalf, with costs recovered through utility rate structures.
3. Design-Build-Operate-Maintain (DBOM) Contracts: Comprehensive project delivery contracts covering the full lifecycle from design through ongoing operations and maintenance, commonly used for public-private partnership (P3) infrastructure projects such as university central utility plants.
4. Public-Private Partnerships (P3): Long-term infrastructure partnerships structured as P3 arrangements where NORESCO co-develops, co-invests, and operates critical energy infrastructure alongside financial partners, with revenue derived from utility cost savings and service fees over multi-decade concession periods.
