Utility resource planners are increasingly adopting Loss of Load Probability (LOLP) modeling to assess the Resource Adequacy of their generation portfolios. In this convention, Effective Load Carrying Capability (ELCC) is used as a metric to quantify the probabilistic resource adequacy contributions of generation resources, such as solar PV, wind, and battery storage, and considers the impacts of temporal and weather-dependent resource variability along with resource saturation effects. In this presentation, E3 proposes to leverage our recent work on a DOE Connected Communities project, and present our methodology that we developed to incorporate shift and shed demand response into this modeling framework. We will also identify trends in high value hours amid the energy transition. Improved data and modeling will help provide utility planners more certainty in the potential contributions of shift and shed demand response, and will help DER practitioners realize longer-term certainty of the benefits stream of their resources.
