About Deanna

Deanna King, co-chair of the firm's energy litigation practice group, represents domestic and foreign energy-industry clients in a broad range of matters related to market access, competition, market behavior and market design, enforcement and compliance, and restructuring and cross-border issues related to participation in United States energy markets.  

She counsels energy sector clients on regulatory and compliance matters and represents them in enforcement, administrative and litigation proceedings, with a particular focus on organized and bilateral energy markets in the west, contract negotiation and dispute resolution, and compliance with market rules. 

Deanna has represented clients participating in agency rulemaking and policy proceedings involving competition, pricing and access to wholesale electricity and transmission markets. Over the past decade, Deanna has played a lead role as counsel for clients in connection with government investigations, contested Federal Energy Regulatory Commission (FERC) proceedings, and litigation involving federally-regulated electricity and transmission markets. Deanna appears on behalf of energy-sector clients in proceedings before FERC and other federal and state agencies, in federal and state courts, and in mediation and arbitration proceedings.

She is a really smart lawyer and does a terrific job representing her clients. She understands the intersection between our business and regulatory policy.
