Wake County sees ice storms in winter and occasional hurricane remnants in late summer. Duke Energy Progress also runs time-of-use rate structures that charge more for power during peak hours, typically 4 to 9 pm on weekdays. A home battery addresses both: it keeps essential circuits running during outages and lets you draw from stored power instead of the grid when rates are highest.
Battery storage has become one of the more requested home upgrades in Raleigh, driven in part by Duke Energy’s PowerPair program, which provides up to $5,400 toward battery installation when paired with new solar.
What installation involves
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 are pairing with solar, the installer coordinates the battery connection with your existing or new solar system. Wake County requires an electrical permit for the work.
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
PowerPair is the main financial incentive currently available for battery storage in Raleigh. It requires installing solar and battery storage together for the first time at your property using a Duke Energy Trade Ally installer.
Battery incentive: $400 per kWh of installed capacity, up to 13.5 kWh. That is a maximum of $5,400 toward your battery. Pair it with the solar incentive ($0.36 per watt, up to 10kW) and the combined maximum reaches $9,000.
If you also enroll in Duke Energy’s Power Manager Battery Control program, you receive the same one-time incentive plus a monthly bill credit based on your battery’s capacity. This option requires allowing Duke Energy to remotely manage when your battery charges and discharges.
The program is first-come, first-served and capacity is limited. You can apply before installation to lock in your incentive reservation, or within 90 days of your system going live.
Pairing with solar in Raleigh
Battery storage and solar work well together in Raleigh. Duke Energy Progress’s net metering program credits excess generation at the retail rate, but a battery lets you store daytime generation and use it in the evening instead of exporting to the grid and buying back power at peak rates. For homes with Duke Energy Progress time-of-use pricing, the combination reduces both your grid dependence and your peak-hour exposure. And with PowerPair, installing both together is the only way to access the battery incentive.
