What Potomac Economics does

Potomac Economics is a privately-held consulting firm headquartered in Fairfax, Virginia, that provides independent market monitoring, expert analysis, and litigation support services to the U.S. electricity and natural gas industries. Founded in 2001 and led by President Dr. David B. Patton, the firm holds designated Independent Market Monitor roles for four major wholesale electricity markets — Midcontinent ISO (MISO), New York ISO (NYISO), ISO New England (ISO-NE), and the Electric Reliability Council of Texas (ERCOT) — and serves as Market Monitor for the Regional Greenhouse Gas Initiative (RGGI) cap-and-trade carbon market and as Independent Market Auditor for the Southeast Energy Exchange Market (SEEM). The firm's core products center on monitoring wholesale electricity market performance, identifying market design flaws and attempts to exercise market power, and producing State of the Market reports, quarterly assessments, and annual filings for regulatory bodies.

The firm operates a recurring revenue model built on long-term contractual engagements with regulatory and quasi-governmental entities, supplemented by professional services revenue from expert consulting, tariff compliance audits, merger compliance monitoring, supply procurement monitoring, and litigation support. Its technology stack comprises proprietary market monitoring analytics and reporting systems that process market data across multiple RTO/ISO footprints, with specific data transfer and storage architecture supporting the SEEM daily compliance screens. The firm distributes its expertise through direct procurement relationships with RTOs/ISOs, FERC, state regulatory commissions, and environmental regulatory bodies, and amplifies its regulatory credibility through an extensive Document Library of reports dating back to 2000 and a Market Insights blog on electricity market topics.

Geographically, Potomac Economics monitors markets across the Northeast (NYISO, ISO-NE), Midwest (MISO), Mid-Atlantic (RGGI states), Southeast (SEEM), and Texas (ERCOT), with stated experience extending to European wholesale electricity markets through its International Market Monitoring practice. The firm competes on the basis of regulatory independence, deep domain expertise accumulated over more than two decades, and the credibility of its senior practitioners in FERC technical conferences and state commission proceedings.
