We’re big advocates for incentivizing electric vehicle (EV) drivers to charge their cars off-peak by offering them a lower retail price per kilowatt-hour (kWh). “Off-peak” periods refer to times when demand for electricity is low. At these times, wholesale electricity prices and emissions per unit of energy are lower as well. Shifting EV charging demand by setting a price signal — sometimes called a “time-varying rate” (TVR) or “time-of-use rate” (TOU) — is a win for everyone: EV drivers, non-EV drivers, the environment, and our electric grid. Right now, the Massachusetts Department of Public Utilities (DPU) is considering whether and how to move forward on this issue — and we wanted to give you an update on progress made so far. (Fair warning: if ever there was a blogpost for the policy wonks, this is it!)
