About Northwestern Corp

Northwestern Corp, operating as Northwestern Energy through its Northwestern Energy Division, is a major utility provider headquartered in the western United States with established service areas spanning Montana, South Dakota, and Nebraska. The company is registered as a corporate entity and for-profit organization in SAM.gov as of October 5, 2004. Northwestern Energy specializes in providing electrical and natural gas utility services to federal government facilities, complemented by specialized infrastructure work including power transmission line installation, transformer replacement, and electrical infrastructure modernization at federal research campuses, national parks, and other government installations.

Northwestern Energy has demonstrated substantial capability across multiple federal agencies through its prime contract portfolio. The company has delivered electrical utility services to the National Institutes of Health's Rocky Mountain Laboratories campus in Hamilton, Montana through numerous blanket purchase agreement call orders, with contract values ranging from under $2,000 to approximately $1.06 million per task order. The company has also provided electrical and natural gas utility services to the Indian Health Service for facilities including Fort Belknap Hospital and Quarters, Blackfeet Dormitory, and various other Indian Health Service locations, with contract values typically ranging from $6,793 to $556,560. Northwestern Energy has served the National Park Service through multiple BPA calls for electrical infrastructure work at Yellowstone National Park, including specialized projects such as installing three-phase overhead power transmission lines at the Mammoth Wastewater Treatment Plant ($297,581), installing transformers at the Laurel Dorm Facility ($80,653), installing a 2,000-amp switchgear at the Old Faithful Water Treatment Facility ($406,451), and various power transmission line upgrades and relocations valued between $7,397 and $70,000.

Northwestern Energy has also supported the Bureau of Reclamation, Naval Facilities Engineering Command for Naval Operational Support Center Montana, and the Department of Agriculture through various utility and infrastructure contracts. All contracts have been awarded through full and open competition with no set-aside designations, reflecting the company's competitive positioning in the federal marketplace.

Northwestern Energy currently holds a single-award Blanket Purchase Agreement (BPA) with the National Institutes of Health, designated as contract number 75N99025A00003, with a 10-year period of performance from October 2024 through October 2031 and a total ceiling value of $15,750,000. This IDV vehicle is for the provision of electrical and natural gas utility services in support of the NIH's Rocky Mountain Laboratories campus in Hamilton, Montana, encompassing electricity and natural gas supply, power line installation and maintenance, and specialized energy solutions for the federal research facility. Northwestern Energy has executed numerous task orders under this BPA since its award, with call orders issued throughout 2024 and 2025 supporting ongoing utility needs at the RML campus. The company previously held a $25 million BPA with the National Park Service for electrical infrastructure services and installations at Yellowstone National Park, effective from December 2020 to November 2030, which generated multiple task orders for transformer installations, power transmission work, and electrical service connections throughout Yellowstone facilities. These IDV vehicles demonstrate Northwestern Energy's strategic positioning as a key utility service provider to major federal research and conservation facilities, with the ability to respond rapidly to mission-critical infrastructure needs through pre-established contract vehicles.
