Yeah.
"We'd like to pour a huge concrete slab and cover it with batteries in shipping containers as this benefits green energy, which isn't necessarily produced when it's needed." Great, I can get behind that - we need a lot of these.
"We want to do it on a greenfield site rather than a brownfield site." That's a bit WTF. Developers always want to build on greenfield sites, since they don't have to check for existing services, but this looks like the most classic kind of 'we can build this shit anywhere' project.
Every industrial estate in the country should have one of these facilities - since they're all containerised, you can tuck them into practically any kind of space. Doesn't make a lot of sense to be building them in the countryside.
