E3 is a leader in cutting-edge electricity planning practices. We support utilities, regulators, and system operators in developing integrated resource plans, capacity expansion studies, and the integrated system planning processes that holistically connect generation, transmission, distribution, and customer resources. We perform this work for vertically integrated utilities, restructured markets, regulators, and system operators across North America.
We use both third-party commercial software such as PLEXOS™as well as our in-house capacity expansion model RESOLVE to perform rigorous analysis. Our experienced team supports utility planners directly, as well as several major regional planning processes, including more than a decade as technical consultant to the California Public Utilities Commission’s integrated resource planning program. We develop least-cost resource plans, test portfolios against reliability and policy constraints, evaluate renewable and storage integration, and build the load forecasts and scenario frameworks that planning depends on.
As load growth accelerates and the resource mix changes, planning processes that were traditionally run in silos must be increasingly connected. E3 has supported utilities developing first-of-a-kind integrated system plans, which coordinate generation, transmission, distribution, and customer resource planning in a single framework. These include the first US Integrated System Plans developed by Hawaiian Electric and Salt River Project in addition to a growing roster of other utilities pursuing a more comprehensive ISP approach. Our perspective across all of these sectors lets us see how the pieces fit together.
