Judy Chang is an energy economist and policy expert with a background in electrical engineering. She has 20 years of experience in advising clients in transmission, resource, and strategic planning.

 She specializes in evaluating the economic benefits of proposed transmission projects, assessing the regulatory and financial risks associated with renewable/clean energy resources and energy storage, and leading utility executives, stakeholders, and board members, in making strategic business decisions. Ms. Chang’s recent planning engagements have involved the development of future energy market scenarios, and leading utilities and grid operators in making market design or investment decisions that are necessary to balance national or regional policy directions and customers’ evolving preferences. Relatedly, she has led transmission system planners, market design experts, and associated stakeholders in improving market design and system planning using a scenario-based approach.

Ms. Chang has served as an expert witness in regulatory proceedings and litigation settings. She has submitted expert testimonies to arbitration panels and regulatory agencies in the U.S. and Canada on topics related to transmission access, transmission pricing, renewable energy development, contract disputes, and power market designs. Her recent experiences involve economic and policy analyses associated with widening regional electricity markets, evaluating the potential impact of integrating renewable energy onto power systems, evaluating the value of proposed transmission projects, and advising companies and governments on energy and environment policies.

Ms. Chang holds a Master’s in Public Policy from Harvard Kennedy School and a Bachelor’s of Science in Electrical Engineering and Computer Science from University of California, Davis. She is a Director of The Brattle Group, a founding Director of New England Women in Energy and the Environment, and a former Director of the Massachusetts Clean Energy Center.
