Member, Energy Bar Association, 1999-present

Dave has extensive experience advising electric utilities and electric cooperatives on legal and policy matters before the Federal Energy Regulatory Commission (FERC) and U.S. Courts of Appeal. His practice focuses on electric transmission matters including open-access transmission service, cost-of-service transmission rates, incentive transmission rates, generation and transmission interconnection matters, and the provision of wholesale distribution service. He also focuses on NERC compliance matters, including self-reports, spot checks and formal audits.

Prior to joining McGuireWoods, Dave was senior counsel for Dominion Resources Services, Inc. In that role he represented Virginia Electric and Power Company (Dominion) in electric transmission matters and NERC compliance. Respecting electric transmission, he worked on Dominion’s forward-looking formula transmission rate and actively participated in the processes set forth in the formula rate protocols. He worked on filings requesting incentive rate treatment for transmission enhancement projects in PJM Interconnection L.L.C (PJM) and modifications to the formula rate to recover deferred PJM start-up costs and administrative fees. He represented Dominion in cost allocation proceedings and was actively involved in the U.S. Court of Appeals for the Seventh Circuit appeal of FERC’s orders involving cost allocation and subsequent remand proceedings before FERC. He has also represented Dominion in matters involving merchant transmission, generator interconnections at both transmission and distribution voltages (including non-jurisdictional generators interconnected at distribution voltages and three-party wholesale market participation agreements), transmission interconnections, and the negotiation of a joint ownership agreement for a jointly-owned transmission line. Also in this role, Dave represented Dominion at PJM's Transmission Owners Agreement-Administrative Committee, serving as chair of the Legal Issues Team in 2007 and 2008. Respecting NERC compliance issues, Dave represented Dominion and its affiliates in connection with settlements of self-reports in different regions, worked on ensuring consistency across Dominion’s NERC compliance program, and has provided counsel on cyber security compliance issues.

Prior to working at Dominion, Dave was with an energy law firm where he worked on rate cases involving firm, non-firm, network integration transmission service, wholesale distribution service, and ancillary services. He drafted ancillary services tariffs, market-based rate tariffs, service agreements, stand-alone rate schedules and other transactional agreements. He worked on transmission interconnection matters and generation interconnection matters including FERC’s Order Nos. 2003 and 2006 rulemaking proceedings. He actively participated in proceedings involving the Midwest ISO, drafted several applications to the Department of Energy to export electricity to Canada and represented a power marketer in Standard Offer Service proceedings before the Maryland Public Service Commission.

While earning his law degree from the University of Baltimore, Dave was honored as a member of the Heuisler Honor Society.
