Idaho offers no state EV tax credit, but federal incentives apply. Idaho Power offers time-of-use plans with off-peak rates that can go even lower. The base $0.11/kWh rate is already competitive with TOU off-peak rates in most states.

Charging Infrastructure

I-84 through Boise is well-covered. North-south stretches (US-95 toward Coeur d'Alene) are improving. Southern Idaho's rural stretches require careful planning. Boise has the best urban charger density.

Grid & Energy Source

Idaho's grid is dominated by hydropower (~65%) from dams on the Snake River and Columbia River system. This makes Idaho EV charging among the cleanest in the US, with among the lowest carbon footprints nationally.
