Washington has the highest EV adoption rate outside California at 8.1%, driven by the Seattle metro area and Amazon, Microsoft, and Boeing employees. Washington's low electricity rates — among the cheapest in the US thanks to hydroelectric power — make home EV charging especially cost-effective.
Western Washington homes built before 1990 — particularly in older Seattle neighborhoods like Beacon Hill, Columbia City, and Ballard — may have Zinsco or Federal Pacific panels that need replacement before EV charging can be safely added. Eastern WA homes tend to be newer and typically have 200-amp service.
