Also 1 GWh of BESS is better used as batteries in 10,000 - 15,000 EVs.

>With Capex of $125/kWh for BESS, 8 GWh of battery backup would cost about a bilion USD. [..] At this scale there just few projects in the pipeline Worth noting there is that Google (alone, and they are one of several) are spending around 200 billion on datacenters this year, and that the 125/kWh figure is a year old and calculated from BESS-projects that need to pay for a lot of things the datacenter already pays for. A datacenter already needs infrastructure to handle a 1GW load, which means it can also deliver 1GW back to the grid. Trucks, cranes, housing, roads and everything else that a BESS-project has to finance separately are already paid for by the datacenter itself. So the "extra cost" would likely be close to the raw cost of the actual battery capacity. It's therefore reasonable to assume that Google & co would pay a lot less than a billion for 8 hours of runtime on batteries. And they are already spending so much that even the billion is no problem. For the communities who will give up 10-15% of the nations electricity production per center, it seems like a sensible demand. Google will still grab their cheap electricity but a 8GWh battery would go a very long way to remove the biggest problems with solar and wind, which can then be built out much more aggressively.
