Shaun C. Mohler principal

Because the price of electrical power is a key cost of production for Shaun Mohler’s clients, he advises and represents these large industrial users in a variety of utility-related matters. These activities may include integrated resource planning, environmental compliance, fuel prices, contracting, generation plant construction, or energy efficiency; all of which relate to the cost that a utility typically attempts to move through rates and fees to their customers. Because of his experience with utility filings and negotiations, his clients turn to him to analyze their electric supply requirements and energy usage to obtain just and reasonable rates for the electric service provided.

A seasoned litigator, Shaun’s work takes him into numerous hearings, where he has developed his skill at drawing out expert testimony to support his clients’ positions, as well as finding the flaws in his opponents’ arguments. He has been involved in numerous FERC proceedings concerning transmission issues and state regulatory proceedings related to electric supply. He has substantial litigation experience at the federal, state, and regulatory level. In addition, Shaun advises and represents clients regarding business, transactional, and regulatory compliance issues, particularly on matters related to electric power supply.

Shaun’s clients include some of the largest steel manufacturers and recyclers in the country, and he represents them and his other clients in federal and state regulatory environments.
