Electric vehicles—are they something utilities should even care about?
Southern California Edison (SCE) certainly does. The utility recently announced it’s preparing itself for the integration projected 350,000 electric vehicles (EV) into its service territory by 2020. SCE studied 12,000 early EV adopters currently in its territory and released a report, “Charged Up: Southern California Edison’s Key Learnings about Electric Vehicles, Customers and Grid Reliability,” detailing the best practices it has developed on the road towards EV grid integration.
Here is what utilities need to know:
1. INFRASTRUCTURE NEEDS TO BE UPGRADED
SCE’s report found that grid infrastructure needs to be upgraded to meet EV-owning customer’s needs and support EV integration:
Since “PEVs can draw as much as another household’s electricity load,” SCE “integrated the expected load from PEVs into its standards” for circuit sizing.
Only 1% of SCE’s transformer upgrades since 2010 have been due to plug-in electric vehicles (PEVs).
SCE upgraded “as needed,” whenever they were notified about a new EV charging station.
Anytime SCE replaced a transformer for other, non-PEV-related reasons, they made sure it met new sizing standards to allow for PEV load.
2. DATA SHOWS MINIMAL GRID IMPACT—FOR NOW
