Technical Advisory Council

The Technical Advisory Council (TAC) supports ESA's research portfolio. The real-world experiences and expertise of the TAC members inform ESA’s research agenda as they review research products and support educational programing. TAC members participate in regular planning meetings as well as ad-hoc discussions and reviews of ESA research efforts. 

The TAC is currently comprised of representatives from two industry consulting firms:

             
     

Ryan Hledik, The Brattle Group

Ryan Hledik is a Principal with The Brattle Group. He specializes in regulatory and planning matters related to the emergence of distributed energy technologies. 

Mr. Hledik has consulted for more than 50 clients across 30 states and eight countries. He has supported utilities, policymakers, law firms, technology firms, research organizations, consumer groups, and wholesale market operators in matters related to energy storage, energy efficiency, demand response, distributed generation, electrification, retail tariff design, and grid modernization.

Mr. Hledik recently directed a study on the potential for energy storage in Nevada, which resulted in the establishment of a statewide energy storage procurement target. He is a recognized voice in debates on how to price electricity for customers with distributed generation, including authoring a report on the topic for the U.S. Department of Energy’s high-profile “Future of Electric Utility Regulation” initiative. He also co-authored Saudi Arabia’s first Demand Side Management (DSM) plan, and the Federal Energy Regulatory Commission’s pathbreaking study, A National Assessment of Demand Response Potential.

Mr. Hledik has published more than 25 articles on emerging electricity issues and has presented at industry events throughout the United States as well as in Brazil, Belgium, Canada, Germany, Poland, South Korea, Saudi Arabia, the United Kingdom, and Vietnam. His research on the “grid edge” has been cited in The New York Times and The Washington Post, and in trade press such as GreenTech Media, Utility Dive, and Vox

Mr. Hledik received his M.S. in Management Science and Engineering from Stanford University, where he concentrated in Energy Economics and Policy. He received his B.S. in Applied Science from the University of Pennsylvania, with minors in Economics and Mathematics. Prior to joining Brattle, Mr. Hledik was a research assistant with Stanford’s Energy Modeling Forum and a research analyst with Charles River Associates.
