None of what they're pledging is much of a change from how they've already been operating:

- They already invest in new power plants and connection infrastructure when they bring in new datacenters - Electricity for datacenters is based on capacity rather than actual usage - They already have backup generators at most datacenters that they can run during outages. It wouldn't be much work to allow those to feed power back into the grid in extraordinary circumstances - They generally use local contractors to build them for practicality purposes anyway.

This is just some fancy PR and nothing else.
