About the company
Noresco, LLC, a subsidiary of Noresco, Inc., is an energy services company that serves as prime contractor on federal energy savings performance contracting (ESPC) projects nationwide, delivering facility energy efficiency improvements, renewable energy systems, and infrastructure modernization without competing under set-aside designations. The company operates from Westborough, Massachusetts, and holds positions on multiple Department of Energy ESPC indefinite-delivery contracts as a primary vehicle for federal energy project work.
Noresco competes almost exclusively as a prime contractor—461 of 468 recent awards (99%) carry prime responsibility—and operates across a broad portfolio of federal customer agencies. The Department of the Army and Army Corps of Engineers Engineering Support Center Huntsville represent the largest customer concentrations by award count (126 and 31 awards respectively), while the Department of Energy Office of Energy Efficiency and Renewable Energy and the Army Corps of Engineers anchor the largest dollar potential by value ($5 billion and $4.95 billion combined potential across their respective award portfolios). The General Services Administration Public Buildings Service, the Department of Justice Federal Bureau of Investigation, and the Department of the Navy Naval Facilities Engineering Command round out the top five customers across both metrics. Over 62 distinct customer agencies have awarded to Noresco, indicating broad federal market penetration, though concentration remains heavy in defense and civilian facility energy modernization.
Noresco's primary federal vehicles are multiple-award indefinite-delivery ESPC contracts. The company holds task orders under the DOE Energy Savings Performance Contracts 2008-2019 vehicle (36 task orders, $1.77 billion combined potential value) and participates in several numbered ESPC generations—ESPC III, the 2017-2022 ESPC, and ESPC Generation 4 (a $5 billion ceiling vehicle)—as well as the ESPC IV multiple-award contract issued by the Army Corps of Engineers. Recent named project work includes a $80.5 million delivery order for ESPC improvements at the Dirksen Federal Courthouse and five additional federal buildings in Chicago through June 2030 (GSA Region 5, firm fixed price); a $129.7 million order for the University of Michigan facility efficiency project through October 2046 (DOE Office of Air and Radiation, ESPC 2017-2022); a $23.4 million Naval Surface Warfare Center Port Hueneme Division facility energy efficiency project through March 2047 (Naval Sea Systems Command, with HUBZone-certified and veteran-owned small business subcontractors including American Building Comfort Services, American Building Automation, and Greentech Energy Services); and a $15.3 million Secret Service order for the James J. Rowley Training Center in Laurel, Maryland through December 2038 (DOE ESPC Generation 4). The company also holds a $3 billion ceiling indefinite-delivery contract from the Army Corps of Engineers for ESPC services awarded in June 2025, with initial task order funding through June 2030.
Activity has remained steady in recent years—two to ten awards per calendar year between 2022 and 2026—with only three awards reaching ultimate completion within the next twenty-four months (combined potential value $151.1 million), indicating limited recompete exposure in the immediate horizon. SCI-reported invoicing across prime service contracts totaled $126.6 million from FY2022 through FY2025, with FY2024 representing peak activity at $37.5 million across 16.2 FTEs. Government-paid hourly rates on SCI-reportable prime contracts range from a tenth-percentile of $552.62 per hour to a median of $1,584.54 per hour and a ninetieth-percentile of $3,536 per hour, reflecting a mix of technical engineering labor and project management work. Noresco self-performs essentially all labor on SCI-reportable prime contracts with zero average subcontractor hour share, indicating a vertically integrated delivery model. The company also acts as a subcontractor on a small number of management services sub-awards under PTSI Managed Services Inc. and as a sub-recipient on federal grant work, including Buildings Showcase program support ($557,217 sub-grant from Colorado Energy Office through September 2029) and software verification standards development ($557,217 equivalent effort through Karpman Consulting, LLC).
