"His knowledge of electric utility regulation in particular has won him a number of admirers, with one describing him as 'an intellectual powerhouse.'"

Chambers USA

For over 25 years, John Lilyestrom has focused his energy law practice on the competitive and commercial consequences of electricity regulation, with particular emphasis on regional transmission operator markets.

John represents modern electric market participants, including electric utility companies, electric power marketers, independent power producers, and end-use consumers of electricity before the Federal Energy Regulatory Commission (FERC), state regulatory agencies, and federal and state courts.

He has represented utilities in mergers and other actions concerning the alleged exercise of generation market power, transmission and wholesale service rates, and the application of standards of conduct and affiliate restrictions. John has also advised electric utilities in assessing commercial opportunities arising from, and the regulatory implications of, electric industry restructuring and corporate reorganization. He has also represented national and regional electric reliability organizations in matters related to the interaction of regulation and electric reliability.

In addition, John has represented utilities, power marketers, and independent generators in negotiating, restructuring and renegotiating power purchase and sale and tolling agreements; interconnection and transmission service agreements; and agreements related to membership in and formation of regional transmission organizations. He has also represented utilities in FERC and state commission proceedings involving the approval and recovery of costs associated with such contracts.
