RI Energy offers an overview of Distributed Generation (DG) hosting capacity via its System
Data Portal: https://systemdataportal.nationalgrid.com/RI/
This includes hosting capacity for a particular substation and/or feeder capacity shown in
a color code by percent available.
Large influx of DG has rendered some substations and feeders at their limit of hosting
capacity. This means any significant sized generator will tip the scale and trigger need for
system upgrades when applying for interconnection.
.
These types of feeders are placed on a challenging feeder list.
A pre-application report (required for 250KW or greater) indicate if interconnecting customer is
in the vicinity of a challenging feeder.
