CORE Electric Cooperative residential solar interconnection
CORE Electric Cooperative's residential solar interconnection process differs from investor-owned utility rules and is set by the co-op.
CORE Electric Cooperative is a member-owned co-op and sets its own residential solar interconnection application, net-metering treatment, and program terms. Homeowners should request current CORE documentation directly rather than assume Xcel rules apply.
