I was looking back at my older post (Supercharger - Hyannis, MA) and see that the Bloom energy 250kW Fuel Cell system plan (page 5) matches the future concrete pad in the pictures above. It's apparently going to be installed right next to the superchargers. The project document indicates this is a backup power system for Stop & Shop, and unrelated to the Superchargers.
I also checked, and the Supercharger electrical permit E-19-777 was closed out 3/10/2020 with an inspection pass.
Anyone on the cape want to swing by to see if there has been any progress since April 11th? Is the meter in place (and if so, is it live)? Are the supercharger cabinets uncovered? TIA
