Subcontractors & Suppliers

Vital to our project success

NORESCO is continuously seeking to grow our national, diverse pool of suppliers, subcontractors, and consultants to implement and maintain energy-efficiency measures for our customers. 

Our projects range from single energy-efficiency retrofits to comprehensive commercial, governmental, institutional or campus-wide implementations and upgrades of energy infrastructure. We procure a full range of materials and supplies (including HVAC equipment, controls systems, and lighting and plumbing fixtures) in the delivery of our projects. To maximize diverse business participation, NORESCO strongly encourages our first-tier contractors and consultants with additional subcontracting opportunities to seek out and solicit small and disadvantaged businesses, as well. Whether updating existing systems or paving the way on P3 projects, NORESCO has access to many contract vehicles across multiple market areas.

It is such a pleasurable experience to be approached by NORESCO (a large corporation) with the understanding that as a small businesses there are challenges that large corporations may not have. Entering into a new market, utilizing our supplier diversity status as a Service Disabled Veteran Owned Small Business some of our challenges were bonding capacities, % of retainage held, cash flow timelines, etc. and every step of the way NORESCO leadership has mentored and believed in our corporation and never viewed us as to small to accomplish major projects and realize lifelong goals. We couldn’t be happier to be a strategic partner with NORESCO and look forward to the future.
