that report puts a 76,800 square foot foundation (so perhaps triple that for total land usage) at $250,000. Is that anywhere remotely in the realms of reality for an area that might actually get permitted and connected at the other assumptions they've made?
UK solar farms generally don’t own the land they’re on, but pay a lease or license fee to the landowners.
A UK comparison would be the proposed Cleve Hill Solar Park in Kent, which will also have on-site battery storage. At 350MW it is almost as large as this LA project.
That's 2400 acres and it's up and running - so I assume permitted and connected to the grid. But I don't know the the total cost to compare things - I'd assume rather cheap, because Yuma is...not a "destination" (outside of maybe a stopover for the dunes).
It wouldn't be in my country (UK).
