Partner, Winston & Strawn LLP
Gordon Coffee is a litigation partner in the firm’s Washington, D.C. office.

Among the energy companies for whom he has served as lead trial counsel are Midland Cogeneration Venture, Allegheny Energy Supply, and USGen New England. Coffee also has effectively represented several other businesses in complex commercial litigation at the trial and appellate levels.
Besides commercial litigation, Coffee has defended energy and health-care companies in battles with federal agencies in federal court and administrative proceedings. He recently won summary judgment for a company seeking a multimillion-dollar refund from a federal agency and assisted hydroelectric generators in challenging onerous license conditions imposed by another federal agency.

Moreover, Coffee has successfully represented several energy companies in federal agency investigations. Notably, he has secured nearly a dozen favorable resolutions of Federal Energy Regulatory Commission (FERC) and North American Electric Reliability Corporation (NERC) investigations and audits. In several cases, he persuaded FERC or NERC to take no adverse action against the company or to dismiss proposed notices of violations. In other instances, his efforts resulted in substantial reductions in penalties proposed by the agency and helped his clients avoid expensive mitigation and compliance plans.
