Microsoft slashes backup power costs with lithium-ion batteries

Microsoft has come up with a way to slash the cost of providing backup power in its data centers using standard lithium-ion batteries like those found in power tools and electric cars.

Microsoft said Tuesday it has submitted the specifications for its Local Energy Storage system to the Open Compute Project, meaning equipment vendors can pick up the design and manufacture it for customers.

The LES can replace traditional UPSes (Uninterruptible Power Supplies) for providing backup power to servers and other IT gear, Microsoft said. A UPS is designed to kick in fast if there’s an interruption to the main power, keeping equipment running during the seconds it takes for a diesel generator to start up and take over.
