Development of Electric Utility IRP
Synapse provided expert witness and consulting services to the Hawaii Division of Consumer Advocacy in a proceeding to develop and review integrated resource plans (IRPs) for three electric companies. Topics included scenario planning, resource modeling, community and stakeholder input processes, and analysis of locally produced biofuels, wind and solar energy opportunities (both distributed and large scale), battery storage, and other renewable energy options. The three major electric companies supplying 95 percent of Hawaii's electricity are simultaneously facing the need to retrofit or replace existing generation impacted by new environmental regulations and the onset of a very stringent renewable portfolio standard (40 percent by 2030). Synapse reviewed these key issues and addressed how best to meet future constraints and policy goals while minimizing costs to consumers. Synapse also provided the Division with production cost modeling analysis to identify avoided costs, including avoided ancillary service costs. We also provided technical support for developing time-of-use rates for distributed energy resources.
