Washington Tests EVs That Power Homes During Outages

Imagine your car powering your home during a blackout while also cutting your electric bill. That's exactly what's happening right now in Washington state.

Puget Sound Energy launched a first-of-its-kind pilot last month testing vehicle-to-home technology with five electric vehicles. Three Ford F-150 Lightnings and two Kia EV9s are showing how bidirectional charging can transform EVs from simple transportation into mobile power stations.

Here's how it works. The vehicles charge up during off-peak hours when electricity is cheap. During expensive peak hours, they send power back to the home, lowering the owner's bill. When the grid gets stressed during high-demand periods, these same vehicles can help stabilize the entire system.

The technology addresses one of the biggest concerns people have about going electric: power outages. Instead of being stuck without transportation or electricity, EV owners gain backup power that can keep their homes running when the grid goes down.

The utility partnered with Ford, Kia, charging equipment maker Wallbox, and ChargeScape to make it happen. The demonstration runs through early 2027, giving researchers real-world data on how well the system performs.

The Ripple Effect

The impact goes beyond individual homeowners. Research from January showed that actively managed EV charging can slash peak demand by more than 50%, which means fewer expensive power plants sitting idle for rare peak moments.

Washington is betting big on electric vehicles anyway. The state requires all new light-duty vehicles sold in 2035 to meet zero-emissions standards, and it set an ambitious (though nonbinding) goal of 100% EV sales by 2030.

This pilot helps solve a critical puzzle piece: integrating more clean energy into the grid. Puget Sound Energy already gets most of its power from clean sources and recently partnered on a massive 200 megawatt battery facility. Vehicle-to-home technology turns every participating EV into a distributed battery, storing renewable energy when it's abundant and releasing it when needed.

ChargeScape CEO Joseph Vellone says the utility will use technical results and participant feedback to shape future programs. If successful, the pilot could expand to include more vehicles and manufacturers as bidirectional charging technology advances.

The program shows how solutions can stack. One technology addresses range anxiety, power reliability, electric bills, grid stability, and clean energy integration all at once.

Washington's clean energy future just got a four-wheeled boost.
