Gregg D. Ottinger

Senior Counsel
  • 1730 Rhode Island Ave, NW, Suite 700
  • Washington, DC 20036
  • 202-289-8450
For over thirty-five years, Gregg’s practice has focused on wholesale power supply and natural resources development. He represents numerous municipalities and consumer-owned electric utilities in their power supply planning, contracting, project development, obtaining and providing interconnection and transmission services, compliance with mandatory reliability standards for operations, planning, critical infrastructure and cyber security, and regulatory proceedings.

In addition to power sales and purchase agreements, transmission service contracts, and contracts with industrial customers, Gregg has helped negotiate and draft contracts for the creation of a power pool, the sale of power from Qualifying Facilities under the Public Utility Regulatory Policies Act, and the first major interconnection agreement in the U.S. to provide unbundled services and in which a “captive” electric utility obtained transmission access to competitive bulk power markets.

He has assisted hydroelectric project developers with FERC permitting, licensing and exemptions from licensing, and served as counsel of record in a successful U.S. Supreme Court proceeding. He has also assisted cities in establishing non-profit, municipally owned electric systems, helped cities negotiate utility franchises to provide lower cost service to local residents and industries, and drafted rules and regulations for municipal utilities.
