A bank of lithium-ion batteries big enough to supply about 500 U.S. homes with electricity during a power outage went online today to demonstrate the future of smart grid technologies.

The 5-megawatt battery is a piece of a larger, government-backed $178 million research project in the Pacific Northwest to make the electric grid more efficient and friendly to additional loads of renewable energy such as wind and solar, which fluctuate depending on the weather and time of day.
