Wake County sees ice storms in winter and occasional hurricane remnants in late summer. Duke Energy Progress offers a voluntary time-of-use rate plan where power costs more during peak demand hours, with the peak window shifting by season. A home battery addresses both concerns: it keeps essential circuits running during outages and lets you draw from stored power instead of the grid when rates are highest.
Duke Energy’s PowerPair program historically helped eligible customers who paired solar and battery for the first time, but Duke Energy Progress capacity is exhausted as of June 2026. Confirm an existing reservation before relying on it.
What home battery installation involves in Raleigh
A home battery system consists of the battery unit, a battery management system, and the electrical integration with your main panel. For outage protection, a critical loads subpanel separates the circuits you want to keep running when the grid goes down. If you’re pairing with solar, the installer coordinates the battery connection with your existing or new solar system. Wake County code requires a permit before electrical equipment is installed, replaced, or relocated.
Costs in Raleigh
Most Raleigh homeowners install one battery unit for partial backup and time-of-use savings. Whole-home backup typically requires two or more units depending on your load. Pairing with solar does not add significantly to the battery installation cost, but the solar side is a separate project with its own costs.
Duke Energy PowerPair
Duke Energy’s PowerPair program has an incentive structure of up to $5,400 toward battery installation ($400 per kWh, max 13.5 kWh) and up to $3,600 toward solar ($0.36 per watt, up to 10kW-AC). Combined maximum is $9,000 when capacity and eligibility are confirmed. It requires solar and battery to be installed together for the first time, using a Duke Energy Trade Ally installer.
Applications are reviewed for eligibility and available capacity. In Raleigh, Duke Energy Progress capacity is exhausted as of June 2026, so contact a Trade Ally installer only to confirm whether an existing reservation or active application path exists.
If you also enroll in Duke Energy’s Power Manager Battery Control program, you may receive a monthly bill credit in exchange for allowing Duke Energy to temporarily adjust your battery during control events. Confirm the exact credit and requirements during enrollment.
Pairing with solar in Raleigh
Battery storage and solar can work well together in Raleigh. Under Duke Energy’s revised net metering riders, export credits are avoided-cost-based rather than the old full-retail structure. A battery lets you store daytime generation and use it later instead of exporting every surplus kilowatt-hour.
