Flexibility Assessment for the Entergy System


In this presentation, Anant Kumar of Charles River Associates and Samrat Datta will discuss an innovative generation flexibility analysis that Entergy conducted in partnership with Charles River Associates. Entergy has committed to achieving net-zero greenhouse gas emissions by 2050, with an interim goal of reducing the utility emissions rate to 50 percent of Entergy’s 2000 emission rate. To achieve this goal, significant changes to Entergy’s largest scope 1 emissions category – power generation – are necessary, including the inclusion of intermittent renewable resources. As numerous studies around the world have demonstrated, energy adequacy (ramping and load following) can be a significant concern with intermittent renewable resources. This presentation will review the process framework of statistical analyses to assess system ramping needs, used by Entergy and Charles River Associates, accompanied by testing of flexible generation capacity adequacy to meet real-time imbalances using Aurora’s sub-hourly production cost modeling capabilities.
