Electric Power Supply Association

What Electric Power Supply Association does

The Electric Power Supply Association (EPSA) is the national trade association representing America's competitive power suppliers, founded in the late 1990s following electricity market restructuring reforms. Headquartered at 1401 New York Ave. NW, Suite 950, Washington, D.C., the organization operates as a private nonprofit membership association with 11-50 employees. EPSA's members collectively represent more than 225,000 MW of reliable, efficient electricity generation capacity from dispatchable and renewable resources, supplying approximately two-thirds of Americans through restructured wholesale electricity markets.

EPSA's core activities are advocacy and regulatory engagement rather than product development. The organization files comments and intervenor petitions before the Federal Energy Regulatory Commission (FERC), provides testimony at state public utility commissions, participates in PJM Interconnection stakeholder processes, and pursues judicial review of adverse agency decisions in federal appellate courts. Major advocacy initiatives include the Energizing Tomorrow campaign (launched 2026) positioning competitive markets as essential to meeting AI and data center electricity demand, challenges to FERC's Order 904 on reactive power compensation, and federal legislative advocacy supporting the GRID Power Act. Supporting member-facing deliverables include the PowerFacts Blog, Energy Solutions Podcast, monthly Power Moves Newsletter, factsheets and white papers, and an annual Competitive Power Summit.

EPSA's revenue model is membership dues from competitive power supply companies, with disclosed members including Constellation, NRG Energy, Calpine, LS Power, Vistra Corp., Capital Power, Competitive Power Ventures, and BP. Revenue figures are not publicly disclosed. The organization is governed by its member companies, with NRG Energy's President and CEO Rob Gaudette serving as Vice Chairman of the EPSA Board of Directors. EPSA operates across all major U.S. competitive electricity markets including PJM, MISO, ISO New England, CAISO, ERCOT, and SPP.

Core offering

EPSA is the national trade association representing America's competitive power suppliers—independent generators that compete in restructured wholesale electricity markets. The organization advocates for competitive wholesale electricity markets through policy positions, regulatory filings at FERC and state commissions, judicial interventions, and industry engagement, representing more than 225,000 MW of generation capacity from member companies including Constellation, NRG Energy, Calpine, LS Power, and Vistra.

Product overview

EPSA operates as a trade association platform rather than a product company. The organization's primary offering is its website platform, which serves as a hub for advocacy content, regulatory filings, news, and educational resources on competitive power markets. Supporting offerings include the Power Moves Newsletter, Energy Solutions Podcast, PowerFacts Blog, and annual Competitive Power Summit event. EPSA does not offer distinct software products or modules—its services are informational and advocacy-focused, centered on representing competitive power suppliers' interests before regulators and policymakers.

Expansion highlights5 records

Direct peers

• American Public Power Association (APPA): National trade association representing not-for-profit, community-owned public power utilities. Like EPSA, APPA advocates for a specific utility ownership model before FERC and Congress, making it the most directly comparable organizational peer.
• Edison Electric Institute (EEI): Trade association representing U.S. investor-owned utilities. EEI is the principal counter-lobby to EPSA at FERC and in Congress, engaging in identical advocacy, regulatory filing, and policy communication work, but on behalf of vertically-integrated monopoly utilities.
• National Rural Electric Cooperative Association (NRECA): Trade association representing rural electric cooperatives. NRECA employs the same dues-funded advocacy model in front of regulators and legislators, and is the third major utility-ownership trade body alongside EPSA and EEI.
• PJM Power Providers Group (P3): Coalition of competitive power suppliers in PJM markets. Per source data, P3 is a core strategic partner of EPSA, filing joint comments, letters, and legal briefs—an essentially overlapping advocacy function specifically within PJM.
• American Clean Power Association (ACP): Trade association representing the wind, solar, storage, and transmission industries. ACP uses the same FERC/state advocacy and policy communications model as EPSA, but is focused on renewable generation rather than the broader competitive power supply constituency.

Emerging players

• Nuclear Energy Institute (NEI): Trade association for the nuclear energy industry. NEI pursues a parallel policy advocacy mission centered on preserving and expanding nuclear generation, with some overlap with EPSA (e.g., ZEC litigation), but a distinct core constituency.
• Solar Energy Industries Association (SEIA): National trade association for the U.S. solar industry. Operates a similar FERC/state advocacy and policy communications model focused on the solar segment, with overlapping competitive-market and interconnection reform interests.
• Advanced Energy United: Industry association representing advanced energy companies across generation, storage, efficiency, and demand response. Similar advocacy structure and shared interest in competitive market design and interconnection reform.

Others

• Consumer Energy Alliance (CEA): Consumer-focused advocacy organization supporting affordable and reliable energy. CEA overlaps with EPSA's messaging on cost savings and reliability benefits of competitive markets, plus shares some policy alignment on grid expansion.
• American Gas Association (AGA): Trade association representing natural gas utilities and pipeline operators. AGA is a parallel energy-sector lobbying organization with similar FERC and congressional engagement, focused on a different but adjacent fuel source.
