Mustafa Ostrander, an accomplished energy regulatory lawyer with more than 20 years of experience advising industry clients on compliance and transactional matters, has joined McGuireWoods as a partner in Washington, D.C.
Ostrander helps energy companies navigate federal regulatory matters — from structuring transactions and securing agency approvals to managing compliance risk and enforcement defense. His clients span the energy value chain, including electric generators, energy marketers, large commercial users, wholesale power suppliers and interstate natural gas pipelines.
Ostrander has significant experience negotiating complex and novel agreements across the energy sector, including power purchase agreements for wind, solar and battery resources; commercial contracts for securing and managing interstate natural gas pipeline capacity; gas supply agreements; and agreements governing interstate petroleum liquids pipeline capacity.
Ostrander’s career includes senior in-house roles with a leading wholesale power provider and a large interstate pipeline operator; associate and partner positions at international law firms; and service in the Federal Energy Regulatory Commission’s Office of Enforcement. He comes to McGuireWoods from Rock Creek Energy Group, a D.C. firm focused on FERC matters.
“Mustafa’s arrival underscores our commitment to serving clients in all sectors of the energy industry, where success requires seamless execution on both the transactional and regulatory fronts,” said Gerald V. Thomas II, McGuireWoods’ deputy managing partner and head of corporate.
Elaine Sanderlin Ryan, chair of the firm’s Regulatory and Compliance Department, said, “Mustafa brings a rare combination of regulatory, transactional and in-house experience that will immediately benefit our clients. As energy markets become increasingly complex, he enhances our ability to help companies manage risk and capture new commercial opportunities.”
McGuireWoods’ Energy Enforcement & Regulatory Counseling Practice Group represents utilities, generators, independent power producers, trading houses and other industry clients in proceedings before FERC, state public service commissions and every regional transmission organization. The group draws on the agency experience of team members, including a former FERC commissioner and former top FERC enforcement officials.
“Mustafa knows firsthand how energy businesses operate and how regulators evaluate complex issues, and that dual lens will help clients anticipate regulatory expectations rather than react to them,” said Todd Mullins, co-leader of the firm’s Energy Enforcement & Regulatory Counseling Practice Group.
McGuireWoods earned nationwide rankings for its energy regulatory, litigation and transactional capabilities in the 2026 editions of Chambers USA and the Legal 500 United States.
“McGuireWoods has built a premier, full-service energy practice,” Ostrander said. “The firm’s expansive reach and deep bench provide the perfect platform to help clients achieve their goals in an evolving regulatory climate.”
“Mustafa brings the blend of agency insight and business acumen our D.C. office is known for,” added Elizabeth Hogan, managing partner of the firm’s D.C. office. “His perspective gives clients the clear sightlines they need to act with confidence.”
