For over twenty years, Wendy has represented a diverse range of energy clients including investor-owned utilities, independent generators, investors in transmission infrastructure and local gas distribution companies before the Federal Energy Regulatory Commission (FERC), the Department of Energy and federal courts.

Her practice focuses on rate regulation, energy market rules and operation, open access transmission issues, administrative litigation, mergers and acquisitions, enforcement and compliance, and authorizations, as well as representing clients in transactional and project finance matters. Wendy enjoys the challenge of representing clients in numerous multi-party, litigated proceedings at FERC concerning rates (from both the utility and customer perspectives), open access, energy markets, mergers and acquisitions, and interconnections. She excels at counseling clients on a wide variety of transactional and compliance matters, including advising on regulatory structuring for project finance,negotiating and drafting varied contracts such as power purchase agreements, fuel supply agreements, and development agreements, and representing and advising clients in public and non-public FERC investigations and audits.

Wendy’s hardwork and dedication to her clients’ business initiatives is often recognized and noted in Chambers USA. For example, Chambers USA says “Sources describe her as ‘a terrific writer . . . very good at getting to the point in her analysis,’”and reported Wendy as “very client-focused, an excellent writer and good in the courtroom too.” Chambers USA goes on to credit her with maintaining “terrific relationships within the FERC regulatory arena” and being a “very good strategic thinker.”
