Webinar: Evaluating Extreme Energy Adequacy Risk using REST

Featured Speaker: Jinye Zhao, Technical Manager, ISO New England Moderator: Erik Ela, Director of System Operation and Electricity Markets, ESIG About the Webinar: As the New England power system increasingly depends on renewable and energy-limited resources, assessing reliability during extreme conditions has become critically important. ISO New England has introduced the Regional Energy Shortfall Threshold (REST), the first metric in the United States designed specifically to measure energy adequacy under extremes. REST offers a transparent, probabilistic standard for evaluating the likelihood and severity of tail-end energy shortfall risks that traditional metrics cannot capture. This presentation will provide an overview of the REST framework and highlight the Probabilistic Energy Adequacy Tool (PEAT), the analytical engine used to quantify the metric. About the Speaker: Jinye Zhao is a Technical Manager in the Advanced Technology Solutions Department at ISO New England. She leads projects involving multidisciplinary teams, applying advanced analytics to address complex challenges in power systems. With more than 15 years of experience in the energy industry, she has extensive expertise in risk management, market design and the integration of emerging technologies. Jinye has played a key role in developing the Regional Energy Shortfall Threshold (REST) and Probabilistic Energy Adequacy Tool (PEAT), advancing New England’s capability to assess energy adequacy under extreme conditions. Jinye holds a Ph.D. degree in Mathematics and actively collaborates with academic and industry partners. She is committed to using innovative approaches to help power systems adapt to a rapidly evolving energy landscape.
