What Clean Energy Group does
Clean Energy Group (CEG) is a 501(c)(3) nonprofit organization founded in 1998 and headquartered in Montpelier, Vermont. It works to advance equitable climate solutions by providing policy analysis, technical assistance, and programmatic support to state energy agencies, local governments, community-based nonprofits, and environmental justice communities across the United States. The organization is organized around four focus areas: Climate Resilience and Community Health, Distributed Energy Access and Equity, Energy Storage and Flexible Demand, and Fossil Fuel Replacement, and operates a portfolio of roughly eleven initiatives including the Technical Assistance Fund, Resilient Power Project, Virtual Power Plant Acceleration, Phase Out Peakers, Climate Resilient Energy Codes, and a newer Data Center Energy Accountability program.
CEG's core "technology" is its research, publications library, and convening capacity rather than any commercial product or platform. The organization produces reports, case studies, model codes, webinars (including the "Beyond Lithium" series covering iron-air, iron-flow, and other long-duration storage technologies), and direct consulting deliverables. Its expertise spans solar+storage systems, long-duration energy storage (iron flow, compressed air, iron-air), virtual power plants, hydrogen pathways, and microgrids. It maintains a four-star Charity Navigator rating and a GuideStar Gold Seal of Transparency.
The business model is grant-funded rather than commercial. Revenue derives from foundation grants, government program funding, and fee-based consulting services delivered to public sector and nonprofit clients (e.g., Massachusetts and Pennsylvania state governments). CEG is not a publicly traded entity, has no disclosed venture funding, and operates as a community-led, mission-driven organization with 11-50 employees and a national footprint spanning all major U.S. regions.

Clean Energy Group competitors and assessment
Company assessmentDirect peers
- Clean Energy States Alliance (CESA): CESA is the directly affiliated coalition of state clean energy agencies that co-launches CEG's national Virtual Power Plant initiative and shares leadership; it is the closest peer given overlapping mission and program scope.
- Rocky Mountain Institute (RMI): RMI is a comparable clean energy nonprofit delivering policy analysis, technical assistance, and program design support to states, utilities, and communities across the same energy transition and equity topics as CEG.
- World Resources Institute: WRI is a peer and active VPP initiative partner; it conducts global energy policy research and technical assistance targeting decarbonization, equity, and distributed energy — directly overlapping CEG's focus areas.
- Environmental and Energy Study Institute (EESI): EESI is a comparable nonprofit that produces policy analysis, educational resources, and briefings on clean energy, energy storage, and equity for federal and state policymakers — directly overlapping CEG's publications and advocacy model.
- Vote Solar: Vote Solar is a clean energy advocacy nonprofit focused on state-level distributed solar and storage policy, mirroring CEG's state-engagement model and competing for similar foundation grants.
- GRID Alternatives: GRID Alternatives is a peer nonprofit deploying solar and storage for low-income and environmental justice communities, overlapping CEG's Resilient Power Project and equity-focused technical assistance.
- Interstate Renewable Energy Council (IREC): IREC is a peer nonprofit building clean energy regulatory and workforce capacity at the state and local level, closely aligned with CEG's technical assistance and policy support model.
Broad incumbents
- Natural Resources Defense Council (NRDC): NRDC is a much larger environmental advocacy organization with parallel clean energy, climate resilience, and equity programs that compete for the same philanthropic and government funding as CEG.
- National Renewable Energy Laboratory (NREL): NREL is a federally funded research lab producing technical analysis on solar, storage, VPPs, and grid integration; it underpins much of the data CEG references and competes for policy-maker mindshare.
- Sierra Club: Sierra Club is a large environmental advocacy organization active in fossil fuel replacement and clean energy policy at the state and federal level, competing for member-driven advocacy funding adjacent to CEG's mission.
