a, Depiction of the ERCOT market, which assumes rail customers have access to wholesale prices. b, Depiction of an illustrative CAISO market which assumes ERCOT’s CPP rate structure and no resource adequacy surcharges. Baseline assumptions include an 80% depth of recharge, eight tender cars per station, 1-h charge time, 7% capital expenditure revenue return53 and 10% efficiency losses in power conversion. Station lifetimes are estimated at 20 years. Generation prices are average hourly prices observed for each market for all hours 2017–2019.
