Interim Rate Waiver 

How can my business save money now?

SDG&E has been authorized by the California Public Utilities Commission (CPUC) to offer an Interim Rate Waiver to DC fast charging (DCFC) and Medium-Duty/Heavy-Duty (MD/HD) electric vehicle (EV) customers. This waiver will allow eligible customers to take service on the existing Small Commercial Time-of-Use (TOU) rate, which has lower demand charges than existing Medium and Large Commercial rates.

TOU-M is otherwise limited to customers with maximum demand below 40 kilowatts.
