Ms. Mazure was in the trenches during the restructuring of both the natural gas pipeline and electric utility industries in the 1980s and 1990s. Ms. Mazure’s degree in economics, with a concentration in regulated industries, affords her a unique ability to analyze complex issues of rate design and allocation, as well as public policy. Those broad experience and knowledge bases allows her to efficiently analyze complex rate, tariff and policy issues, while striving to provide personal attention to achieve each client’s goals.

Ms. Mazure’s experience includes involvement in every facet of utility regulation and administrative law. She has been lead counsel for numerous clients in litigated proceedings involving natural gas pipeline rate, tariff, complaint and certificate proceedings, as well as numerous proceedings regarding electric rates and tariffs, utility mergers, rulemaking proposals, oil pipeline and hydro-electric proceedings. Ms. Mazure coordinates teams including clients, technical and policy consultants, and aligned parties to develop overall case strategies and implements those strategies through review of initial filings or proposals, motions practice, formal and informal discovery, the development of testimony, propounding and replying to discovery, cross-examining and defending witnesses, briefing and appeals of administrative agency decisions.

In addition to litigation and appellate matters, Ms. Mazure regularly advises clients with respect to rulemaking proceedings and policy matters; application of, and proposed revisions to, legislation; rates and operating conditions proposed by Hinshaw and section 311 pipelines; compliance and enforcement matters; transactional matters; matters involving the Public Utility Regulatory Policies Act; and the development of energy projects.
