Judy Chang is an economist with a public policy background. She has expertise in the analysis of electricity power markets and advises clients on the financial and regulatory issues relating to renewable energy investment and procurement decisions. She is experienced in leading utility executives, board members, and stakeholders in making challenging strategic decisions complicated by pressures from customers, policy-makers, regulators, and wholesale and retail competitors. Ms. Chang’s recent long-term strategic planning engagements have involved the development of future energy market scenarios and assisting utilities to make strategic decisions that balance regulatory requirements for renewable energy, energy efficiency, other demand-side resources, with the potential retirement of existing generation facilities due to various environmental regulations. These projects involved close analyses of relevant regulatory and economic issues surrounding system planning, including considerations for financial, operational, and market design issues.

Ms. Chang has authored numerous expert reports and submitted expert testimony before the U.S. Federal Energy Regulatory Commission and state regulatory authorities regarding power market issues. She has served as an expert witness in regulatory proceedings and litigation settings. Recently, she was an expert witness in evaluating long-term power purchase agreements between renewable energy developers and electric utilities. Her other recent work includes evaluating the potential impact of integrating renewable energy onto power systems. Accordingly, she has designed and helped develop a model that estimates the operational effects and the associated costs of variable resources on a grid.

Ms. Chang has authored a number of articles and reports and presented at a variety of industry conferences. She recently spent two years in India, where she worked on evaluating and financing renewable energy investments for international and multilateral agencies. She holds a Master’s in Public Policy from Harvard University’s Kennedy School of Government, is a member of the Board of Directors of the Massachusetts Clean Energy Center, and the founding Executive Director of New England Women in Energy and the Environment.
