Adrienne E Clair

For more than 20 years, Adrienne Clair has provided clients with comprehensive electric and gas pipeline compliance, enforcement, and litigation services — earning her the trust and respect of both utilities and the energy bar.

Adrienne represents primarily cooperative and municipal utilities in applications, litigation and rulemaking proceedings before the Federal Energy Regulatory Commission (FERC). As the energy landscape is shifting, Adrienne guides energy industry clients through issues related to Regional Transmission Organizations (RTO) and Independent System Operator (ISO) markets, including capacity and energy, as well as matters involving transmission planning, cost allocation, natural gas pipeline rates and services, and the changing nature and volume of transmission grid usage.

Adrienne handles routine compliance matters such as compliance program design and audits. She also has assisted clients with FERC enforcement actions. Additionally, Adrienne helps clients to obtain market-based rate authority and comply with relevant reporting requirements. The scope of her experience has enriched Adrienne’s practice, contextually, in a way that provides additional value to clients. Together with her colleagues in Thompson Coburn’s energy group, Adrienne brings to her clients a breadth of experience in most geographic regions and markets in the country and puts that experience to use in tailoring solutions for individual clients.

Adrienne litigates proceedings before FERC, including electric cooperative wholesale power contract and rate design issues, cost-of-service revenue requirements, mergers, and transmission formula rate and cost recovery matters. She also represents clients in FERC-related appellate proceedings and practices before the D.C. Public Service Commission in electric utility and natural gas local distribution company matters.
