Industry overview
Companies classified under SIC 4991, Cogeneration Services & Small Power Producers, develop and operate facilities that simultaneously generate electricity and useful thermal energy, often from natural gas, biomass, waste heat, or other distributed resources. Their core offerings include power purchase agreements, on-site combined heat and power plants, microgrids, and renewable-independent power projects tailored for industrial manufacturers, hospitals, universities, commercial campuses, and municipal utilities seeking lower energy costs and improved resiliency. Revenue is typically tied to long-term contracts, but operators face exposure to fuel price volatility, counterparty credit risk, interconnection constraints, and evolving federal and state regulations governing wholesale power markets, emissions standards, and incentives such as the Inflation Reduction Act tax credits. Key 2024–2025 trends include growing demand for decarbonization, data center capacity, and grid-edge reliability solutions, plus heightened scrutiny of project financing structures and cyber-physical security.
