As more electric vehicles (EVs) hit the road across the US and require charging, utilities and grid operators will be faced with a growing challenge – how to most effectively manage the addition of millions of large, connected, temporally- and spatially-dynamic loads to their systems. Most estimates measure the additional energy load potential from EV charging in terawatt-hours – billions of kilowatt-hours – and suggest that aggregate new EV charging load by 2030 could represent between 1.5% and 8.6% [ 1 ] of the US’s current total electric energy consumption, which currently stands at about 3,900 TWh per year [ 2 ] . On the demand side, estimates of load impacts from EV charging are similarly staggering, with one study estimating that unmanaged EV charging will add nearly 5 GW to California’s peak demand by 2030 [ 3 ] , to say nothing of similar peak demand impacts in other states.
