Make Energy-Efficient Home Improvements More Affordable
Making your home more energy efficient can help improve comfort while reducing energy use. If your home is served by a participating Massachusetts Municipal Light Plant (MLP), the DOER Z-Loan Program may help make qualifying energy-efficiency improvements more affordable.
Pentucket Bank is a participating lender in the DOER Z-Loan Program, offering eligible homeowners financing of up to $25,000 for authorized energy-efficiency improvements. The program is administered on behalf of the Massachusetts Department of Energy Resources (DOER).
0% Interest for Eligible Improvements
Under the current program, DOER subsidizes 100% of the gross loan interest rate, resulting in a 0% interest rate for the borrower. The interest subsidy is subject to change.
Financing is available for up to the lesser of the authorized project amount or the program maximum of $25,000, after applicable rebates provided by the Municipal Light Plant.
Who Is Eligible?
The DOER Z-Loan is available to eligible residential customers served by participating Massachusetts Municipal Light Plants.
Before applying for financing through Pentucket Bank, you'll need to complete an Energy Assessment or another qualifying visit with a vendor approved by your Municipal Light Plant. The approved vendor will provide a dated Z-Loan Authorization Form containing your unique Z-Loan ID and identifying the improvements and project costs eligible for financing.
How the Z-Loan Process Works
1. Complete an Assessment or Qualifying Visit
Work with a vendor approved by your Municipal Light Plant to complete an Energy Assessment or another qualifying visit and identify eligible energy-efficiency improvements.
2. Receive Your Z-Loan Authorization Form
Your approved vendor will provide a dated Loan Authorization Form with your unique Z-Loan ID, authorized work and eligible financing amount.
3. Apply with Pentucket Bank
Once you have your Z-Loan Authorization Form, apply for financing through Pentucket Bank. You'll need to provide the Bank with your completed loan application and dated Z-Loan Authorization Form.
4. Finance Your Energy-Efficiency Project
If approved, your loan can finance the authorized work identified on your Z-Loan Authorization Form, subject to program limits. Loan proceeds are issued by two-party check payable to both you and the contractor identified on your authorization form.
