Since 2021, EPRI, the National Renewable Energy Laboratory, Lawrence Berkeley National Laboratory, and seven electric utilities have been exploring the propensity of residential and commercial customers to adopt a range DER technologies (solar PV, energy storage, and/or electric vehicles and attendant charging infrastructure). Funded by the DOE, this effort has entailed collecting/analyzing a comprehensive survey data set to discern customer adoption preferences, assessing real-world customer interconnection and premise-level metering data to determine baseline customer load shapes from which to extrapolate the effects of DER adoption, and developing a forecasting tool for modeling national/regional adoption outlooks. This presentation will describe key takeaways from the stated and revealed customer survey results, and then focus in on the implications of DER adoption on customer energy use. It will discuss the time-differentiated and aggregate differences in consumption between DER non-adopters, singular adopters, and co-adopters to characterize prospective load shape management opportunities.
