In 2023, Apex Analytics conducted research for the Regional Technical Forum (RTF) to characterize the electric vehicle (EV) market. The study’s goal was to assess the EV market, determine “competition” groups, testing methods, data availability, energy efficiency and DR opportunities, with the end goal to determine the potential for the RTF to develop a new efficiency savings measure. The study was focused on personal, light-duty battery EVs. The study identified two approaches to determining EV efficiency but found significant issues with each thereby limiting the potential for developing a measure.
