Microsoft's Dublin datacenter to help take pressure off Ireland's renewable energy

elsergiovolador Silver badge


allows facilities such as datacenters to - if necessary - feed some power back to the grid from their backup energy storage systems, typically large banks of lithium-ion batteries managed by a UPS system.

Why would datacentre draw more energy than it needs to and then send it back to the grid?

Maybe it will draw energy when the tariff is cheap and then send it back when the margin is right to make profit?

How much energy is going to be wasted because of this?
