However, even states without California’s abundant sunshine can still produce low-cost solar power, thanks to declining solar-panel prices. The vast majority of sites in the study have sufficient buildable land to install solar projects.
Phadke added that building off-grid systems would give factories faster access to renewables, since grid-tied wind and solar farms have to wait in long interconnection queues, which can delay projects for years. Ditching the utility would also let manufacturers avoid paying steep grid-delivery charges and other expenses — and sidestep competition with data center operators for power from an increasingly strained grid.
The new site-level data “is really helpful for project developers and technology developers to know how to prioritize their efforts, in terms of where to go and pitch industries on,” said José Domínguez, the study’s lead author and a research affiliate at the Goldman School.
Making on-grid power cheaper
The fact remains, though, that many factories will continue to rely on the electric grid in the near term. To get these facilities to consider transitioning to cleaner heat, the cost of electricity needs to come down.
