Duke Energy Progress — NOT Duke Energy Carolinas — Serves Raleigh

Duke Energy Progress Serves Raleigh. Duke Energy Carolinas Serves Charlotte. Different Subsidiaries, Different Applications. Submitting the Wrong One Gets Rejected Immediately.

Duke Energy Progress and Duke Energy Carolinas are separate subsidiaries of Duke Energy Corporation with different service territories and different interconnection applications. Duke Energy Progress serves Raleigh, Durham, the Research Triangle, and eastern NC. Duke Energy Carolinas serves Charlotte and western NC. Installers who work both markets must use the correct subsidiary for each address. Wake County Inspections handles permits for most of the Raleigh metro, but Cary, Apex, Holly Springs, Morrisville, and Durham maintain separate departments.

Why Raleigh Installers Outsource

Wrong Duke Subsidiary. AHJ Mismatch. NC Net Metering Terms Misunderstood.

📋
Submitting a Duke Energy Carolinas Application for a Duke Energy Progress Address
Duke Energy Progress and Duke Energy Carolinas are separate subsidiaries with separate interconnection portals and forms. Installers who work Charlotte (Carolinas) and Raleigh (Progress) must use different applications for each. A Duke Carolinas application for a Raleigh address is rejected by Duke Energy Progress interconnection. We confirm the correct subsidiary before building every Raleigh plan set.
🏙️
Routing a Cary or Apex Address to Wake County Inspections
Cary, Apex, Holly Springs, Morrisville, and Fuquay-Varina maintain their own building departments separate from Wake County Inspections. A plan set addressed to Wake County for a Cary address routes to the wrong department. We confirm AHJ per address before building every Raleigh metro plan set.
NC Net Metering — Understanding Current Terms and What NCUC Has Considered
NC net metering has been subject to ongoing North Carolina Utilities Commission proceedings. NC law requires Duke Energy Progress to offer net metering at the retail rate, but proposed rate structure changes have been discussed. Installers should communicate current program terms accurately rather than assuming the program is identical to other markets. We include current program notes in every Raleigh deliverable.

Four Things That Define Solar in Raleigh.

Duke Progress
Duke Energy Progress — Separate Subsidiary Serving Raleigh and Eastern NC
Duke Energy Progress and Duke Energy Carolinas are distinct subsidiaries with separate service territories, separate interconnection applications, and separate contacts. Duke Energy Progress serves Raleigh, Durham, Chapel Hill, and eastern North Carolina. Duke Energy Carolinas serves Charlotte and western NC. Installers who work both markets must file different applications for each address. Mixing up the subsidiaries results in immediate rejection of the interconnection application.
NC NEM
North Carolina Net Metering — Full Retail Rate, Required by State Law
North Carolina law requires Duke Energy Progress to offer net metering for residential solar, crediting exports at the full retail electricity rate. NC net metering has been subject to ongoing NCUC proceedings around demand charges and rate structure. Current Raleigh residential customers receive full retail rate credits. NC also has a property tax exclusion for solar energy equipment, and no state income tax credit for solar in 2026.
Research Triangle
Research Triangle — Tech and University Market Drives Strong Solar Demand
Raleigh-Durham-Chapel Hill is home to NC State University, Duke University, UNC Chapel Hill, and one of the highest concentrations of tech and biotech companies in the Southeast. This workforce is solar-favorable: higher income, education level, and environmental awareness. New construction in North Raleigh, Cary, and Morrisville adds consistent residential solar volume.
Wake County
Wake County Inspections — Primary AHJ for Most of the Raleigh Metro
Wake County Inspections handles permits for the City of Raleigh and most unincorporated Wake County. Cary, Apex, Holly Springs, Morrisville, Fuquay-Varina, and Garner maintain their own building departments. Durham, Chapel Hill, and Carrboro use their own departments in Durham and Orange counties. We confirm the exact AHJ per address before building every Raleigh plan set.
