System Advisor Model (SAM) Software Development

The Alliance for Energy Innovation, LLC, acting as a contractor to the Department of Energy’s National Laboratory of the Rockies, has issued a Sources Sought Notice to conduct market research on the capabilities of potential vendors to support the development, maintenance, and enhancement of the System Advisor Model (SAM), an open-source software platform used for modeling the technical and economic performance of renewable energy systems including solar, wind, and geothermal technologies. Respondents are expected to demonstrate proven expertise in C++ software development, object-oriented architecture, and GUI development using wxWidgets, along with experience in energy and financial modeling across multiple markets. The effort requires the ability to deliver cross-platform software support for Windows, Linux, and macOS, perform ongoing troubleshooting and testing of production code, and collaborate effectively with technical subject matter experts to support annual software releases and long-term platform modernization. The scope focuses on software improvements rather than physical deliverables, with performance expected to be conducted in Golden, Colorado, and no physical packaging, labeling, or military standards apply. Responses must be submitted as a single PDF not exceeding two pages, excluding a cover page, via email to ASP.Responses@nlr.gov by July 10, 2026, with the subject line formatted as SS-2026030923 followed by the company name. The solicitation number is SS-2026030923, and the NAICS code is 541511 for Custom Computer Programming Services. While no formal contract, evaluation criteria, or binding clauses are present, the notice requests respondents to provide their size status and socioeconomic certifications—including Small Business, WOSB, SDVOSB, 8(a), and HUBZone—as the government is evaluating potential use of a small business set-aside in a future solicitation. No UEI or CAGE codes are required, and no payment, invoicing, or contract administration details are applicable at this stage; this notice serves solely as market research to inform a potential future procurement, and responses will not constitute offers or bids.
