The electrical utility DTE, in Michigan, required Google to do this for their new datacenter ("Project Cannoli") to avoid increasing consumer energy prices. They are building solar and battery storage to serve the load, as it is the cheapest and fastest new generation that can be built.

I see nothing wrong with power users committing to clean energy and storage to accelerate their development plans, or to allow them at all. I am unsure who is going to complain about this model. Lease or buy as much land as you need to deploy clean energy.

> Google’s data center operations will be served by 2.7 gigawatts (GW) of new resources for the grid, including solar power, advanced storage technologies and demand flexibility. This Clean Capacity Acceleration Agreement with DTE (the same structure as the Clean Transition Tariff) will bring new, clean resources online, while supporting the state’s transition away from coal-fired power. As part of our standard approach to building new data centers, Google will fully cover its electricity costs and infrastructure needs, helping to ensure that its growth protects local ratepayers and actively bolsters the long-term resilience of the state’s electricity grid.
