Natural Gas Pipelines

Wendy represents a diverse range of energy clients, including investor-owned utilities, regional transmission organizations (RTOs), 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. With over twenty-five years of experience, Wendy’s hard work and dedication to her client’s business initiatives has earned her recognition, including being recognized by Chambers USA in 2023 as “very intelligent, experienced and her advice is pragmatic.”

Her practice focuses on rate regulation, energy market rules and operation, open access transmission and interconnection 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.
