Add thermal storage and get up to $75 per kilowatt in rebates.
Thermal-storage systems allow for heating (or cooling) to be created during off-peak hours and then used as needed—saving you money with off-peak rates and thermal-storage rebates!
Install a thermal-storage system in your home or business and become eligible for both off-peak rates and associated rebates. Thermal-storage system options include:
Thermal-storage cooling systems—most often used in commercial cooling systems—are also eligible.
To be eligible for rebates, thermal-storage systems must take advantage of qualified off-peak rates.
Your system must have adequate storage capacity to fully heat or cool during the maximum control period allowed by the rate serving the system. Electric cable or panel storage rebates are limited to under slab installations with storage capacity (usually in several inches of sand beneath the slab).
Once your installation is complete, fill out the rebate form and attach all required documentation, then mail it to:
