Webinar: Assessing Capacity Accreditation Choice on Resource Mix Outcomes

Featured Speaker: Genevieve de Mijolla, Technical Leader, Electric Power Research Institute (EPRI)
Moderator: James Okullo, Director of System Planning, ESIG
About the Webinar: A variety of capacity accreditation methods are used in power system planning, but the implications of choosing one approach over another for capacity expansion decisions are not always well understood. This webinar explores how different approaches to accrediting wind capacity influence planning outcomes, using an iterative workflow that links capacity expansion and resource adequacy modeling. By comparing several capacity accreditation methods, the discussion highlights how methodological choices can lead to meaningfully different capacity values and investment signals. The analysis also illustrates why system-wide wind capacity values can overlook important spatial and temporal adequacy considerations, and how closer alignment between planning and adequacy assessments, such as through regional capacity values, can improve decision-making.
About the Speaker: Genevieve de Mijolla is a Technical Leader at EPRI where she leads the Resource Adequacy Assessments project set. She joined EPRI in 2021, and has since contributed to a number of projects, most notably to EPRI’s “Resource Adequacy for a Decarbonized Future” initiative. She is also the chair of the IEEE Resource Adequacy Working Group. Prior to joining EPRI, she worked for GE Energy Consulting on production cost modeling and renewable integration projects. She holds a master’s degree in electrical engineering from the Rensselaer Polytechnic Institute.
