Mark is a partner in the Energy Section of the Washington, D.C. office. Since 1981 he has been extensively engaged in the representation of energy industry participants before federal and state agencies charged with jurisdiction over energy markets and their participants. His representations have focused on the rates, terms, and conditions associated with gaining access to regulated energy transmission systems, transactions involving changes in ownership of jurisdictional assets, and unbundling matters. Particularly, Mark’s practice includes a wide array of issues under the Natural Gas Act, the Federal Power Act, and related federal and state statutes involving the regulation of energy industry participants.

He has been involved in counseling and representing before the Federal Energy Regulatory Commission multiple merchants of electric power in the Southeast U.S., and New England.  He is defending entities doing business in the California and the Pacific Northwest that have been accused of charging rates for electricity and capacity inconsistent with the standards of the FPA.  He also has appeared before the regulatory commissions of numerous states on behalf of end users and coalitions of market participants.

His work frequently requires the integration of both transactional and regulatory goals.  Over the past three years, Mark has forged durable, commercially-resilient agreements to transactional and regulatory disputes arising between energy market participants.  Some of the disputes had been underway for 10 years before resolution.  In like fashion, Mark has addressed commercial challenges in negotiating arrangements for new projects, allocating capacity, and designing and implementing open seasons with creative, commercially-viable solutions.
