The Insulation Program is designed to improve the energy performance and durability of existing residential housing in DTE service territories. The program offers financial incentives to homeowners for the installation of qualifying insulation measures in eligible single- and multifamily dwellings (2 or fewer connected units).

The objective of the program is to increase the demand for energy-efficient improvements for insulation to produce long-term electric and natural gas energy savings to DTE residential customers. The rebates help offset the cost difference between choosing a standard product and an energy-efficient one.

DTE Energy INWIN Program 2022-2023 Updates

Thank you for your continued support of the Insulation and Windows (INWIN) Program. A friendly reminder to please submit all 2022 outstanding applications as soon as possible.

Federal Tax Credits Have Been Extended

As part of the Inflation Reduction Act (IRA) of 2022, federal tax credits for energy efficient home upgrades have been extended. Any qualifying home improvements to your customer’s primary residence completed after December 31, 2021, may be eligible for federal tax credits when filing for tax year 2022. This is an opportunity for your customers to potentially offset the cost of their qualifying home improvements even further. 

2022 DTE INWIN Program Transition

To begin the 2022 program year, rebates for DTE residential INWIN measures will remain the same as they were in 2021. Updated 2022 program materials will be available in the coming weeks. Materials will be distributed via email and available for order through our Digital StoreFront.
