Will Huge Batteries Save Us From Power Blackouts?

Glacier, Washington, is the final stop for coffee and treats on the Mt. Baker Highway, which ends at a ski area holding the world record for most snowfall in a season. The small town in the woods might seem an unlikely spot for a $9.6 million warehouse to store excess energy, but it might prove the perfect testing ground.

The area’s winter storms routinely knock out power to Glacier, home to about 250 residents year-round and more than 1,000 on busy weekends. Come 2016, its outages should be less frequent thanks to a shipping container humming with lithium-ion batteries hooked up to a substation that will provide up to 18 hours of backup electricity.

The two-megawatt system will allow Puget Sound Energy to study broader applications for grid-scale energy storage such as using it to provide power during peak-hour demand and to maintain minute-by-minute grid balance.
