Hydroelectric Power Generation

This U.S. industry comprises establishments primarily engaged in operating hydroelectric power generation facilities. These facilities use water power to drive a turbine and produce electric energy. The electric energy produced in these establishments is provided to electric power transmission systems or to electric power distribution systems. Show more

NAICS 221111 – Hydroelectric Power Generation encompasses the production of electricity through the controlled flow of water through turbines in dams, run-of-river facilities, and pumped storage systems. This sector involves the operation, maintenance, and modernization of hydroelectric infrastructure, including penstocks, spillways, turbine-generators, and grid interconnection systems.

NAICS 221111 – Hydroelectric Power Generation encompasses the production of electricity through the controlled flow of water through turbines in dams, run-of-river facilities, and pumped storage systems. This sector involves the operation, maintenance, and modernization of hydroelectric infrastructure, including penstocks, spillways, turbine-generators, and grid interconnection systems. In the federal contracting landscape, this NAICS supports mission-critical energy resilience initiatives, particularly for remote military installations, defense-dependent water infrastructure, and sustainability compliance under federal energy mandates. Projects often require specialized engineering expertise in hydraulic modeling, environmental permitting, and relicensing under the Federal Energy Regulatory Commission (FERC) framework. The top contractor in this sector is MST MARITIME MANAGEMENT LLC, a small business specializing in marine and water infrastructure support services. Its presence suggests a niche competitive landscape dominated by firms with expertise in aquatic systems, dam operations, and federal compliance rather than large-scale utility contractors. The market is characterized by high barriers to entry due to regulatory complexity, long project cycles, and the need for site-specific engineering knowledge. The Department of Defense is the primary federal buyer, driving demand through energy security programs, installation resilience planning, and renewable energy portfolio goals. Hydroelectric facilities on or near military bases—particularly those managed by the Army Corps of Engineers or Navy installations—represent key procurement targets for reliable, low-carbon baseload power. The market exhibits low contractor density and high specialization, favoring firms with proven experience in federal water resource management and FERC-regulated hydropower operations. Opportunities exist for contractors with capabilities in turbine retrofits, fish passage upgrades, and digital monitoring systems, particularly as agencies prioritize aging infrastructure renewal and climate adaptation. Contracting activity is steady but concentrated, with long-term maintenance and modernization contracts dominating over new construction.

Electrical Energy Power Generation Equipment with Related Parts, Supplies, and ServicesThe Saskatchewan Association of Rural Municipalities (SARM), in partnership with Canoe Procurement Group of Canada and Sourcewell, is seeking proposals for electrical energy power generation equipment along with related parts, supplies, and services to establish a national contracting solution. This solicitation, designated as SK-RFP062326, is open to a broad spectrum of public sector entities across Canada, including rural and urban municipalities, K-12 and higher education institutions, not-for-profits, tribal governments, provincial and federal agencies, and crown corporations. The initiative leverages competitive procurement processes aligned with Canadian trade agreements such as the Canadian Free Trade Agreement, CETA, NWPTA, and ATPP to ensure compliance and market access. Eligible participants include all members of SARM and its network of represented associations from every province and territory. Proposals must be submitted exclusively through the Sourcewell Procurement Portal by the deadline of June 23, 2026, at 3:30 p.m. Central Time, with no late submissions accepted. The solicitation is led by SARM as the originating agency, though it is administered through Sourcewell’s platform and supported by a consortium of provincial and territorial associations. Performance of any resulting contract will be focused within Saskatchewan but will enable widespread use across Canada. The point of contact for the solicitation is the Sourcewell Procurement Portal, which serves as the sole conduit for submissions and inquiries. All awarded contracts will aim to provide cost-effective, reliable, and standardized access to power generation solutions for thousands of public organizations throughout the country.

On-Call Generation Engineering ServicesSeattle City Light is seeking qualified consulting firms to provide on-call generation engineering services through a Request for Qualifications (RFQ) process. These services will support the engineering, operations, and project delivery teams for City Light’s hydroelectric generation portfolio, which includes seven hydroelectric powerhouses associated with six City Light-owned dams—Boundary, Ross, Diablo, Gorge, Newhalem Creek, and Cedar Falls Masonry Dam—as well as the South Fork Tolt Dam owned by Seattle Public Utilities. Those dams are regulated either by the Federal Energy Regulatory Commission or the Washington State Department of Ecology, with all facilities located within Washington State. The contract anticipates multiple awards to prime consultants or consortiums composed of one or more firms, with an emphasis on inclusive participation from Women and Minority Business Enterprises (WMBE). Services will be contracted via individual task orders under general contracts, allowing flexibility to assign work based on consultant expertise and past performance. The scope includes engineering and related professional services that support both operation and maintenance activities and capital improvement projects under City Light’s Generation Operations and Facilities budget. The RFQ was posted in January 2026 with a submission deadline in late February 2026, and the contract will be managed by Seattle City Light’s procurement team based in Seattle, Washington. The solicitation encourages collaborative teams and sets the framework for ongoing, as-needed support to maintain and improve the generation assets powering the region.
