Seattle's forecourts, Shell, Chevron, 76, Arco and Costco (born here), line I-5, SR-99 and the 405 loop, with Washington prices among the highest outside California. EIA weekly data gives official coverage. EV charging is dense and growing, backed by cheap hydro electricity.
Local tips
- Arco and Costco Business Center sites set the price floor in the metro.
- I-5 through downtown jams badly, so don't count on a quick fill mid-commute.
- Cheap hydro power makes EV charging here among the best-value in the U.S.
