Duke Energy’s new solar rebate program, required by 2017’s House Bill 589, is already supporting a rapid increase in rooftop solar construction in North Carolina. NCSEA’s Market Innovation Team actively tracks reports of new rooftop solar construction by examining Report of Proposed Construction (ROPC) filings at the North Carolina Utilities Commission. Our Market Innovation Team can report a marked increase in residential rooftop solar filings since the rebate program’s effective date of January 1, 2018. The first quarter of 2018 is on track to report more than 600 filings for rooftop solar construction, which will be the second most in any quarter over the past six years, and 98% of filings in the first quarter of 2018 are residential systems. This will be the most-ever reported ROPCs in the first quarter of any year; for reference, the first quarter has averaged 267 ROPCs since 2012.

The ROPC filings indicate the following capacity totals for Duke Energy Carolinas’ and Duke Energy Progress’ service territories:
