Shared Solar (HB 589) · Duke Energy Carolinas / Progress · NC Utilities Commission · Duke Energy
North Carolina's shared-solar program runs through Duke Energy under HB 589 (the 2017 Competitive Energy Solutions for NC Act). The state is one of the largest solar markets in the country - and shared-solar capacity is opening to non-Duke-built projects as the program expands.
Project cap
Up to 5 MW AC per shared-solar facility
Typical savings
5–15% off subscriber bill credits
LMI requirement
Low-income carve-out under Duke's Shared Solar tariff

Program overview
North Carolina authorized shared/community solar through the Competitive Energy Solutions for NC Act (HB 589, 2017), which directed Duke Energy to file Shared Solar tariffs with the NC Utilities Commission. The program serves residential and small-business customers in Duke Energy Carolinas and Duke Energy Progress territory, with a dedicated low-income subscriber carve-out and bill-credit compensation. NCUC has continued to refine subscriber protections, project siting, and capacity allocations through 2024–25.
The laws & rules
The foundational statute that authorized Duke Energy to develop shared-solar facilities, established subscriber rules, and directed NCUC to oversee program design.
Duke Energy Carolinas and Duke Energy Progress each operate Shared Solar riders approved by the NC Utilities Commission. Bill credits are calculated on a per-kWh basis tied to the production share of the subscribed facility.
A defined percentage of capacity in each Shared Solar offering is reserved for low-income subscribers, with deeper bill-credit guarantees and reduced enrollment friction.
Shared-solar facilities are capped at 5 MW AC. Projects must be sited within Duke service territory and meet NCUC interconnection and consumer-protection requirements.
