Unitil - Residential Energy Efficiency Programs

September 08, 2009


Northern Utilities offers two weatherization programs. Through the Partners in Energy Weatherization Program, customers can receive rebates of 50% to 75% of the costs associated with purchasing and installing weatherization improvements, such as attic/wall insulation and air sealing. Homeowners are eligible for 50%, up to $1,500, and tenants can receive 75% of the cost, up to $1,500. Low-income customers are eligible to receive weatherization improvements at no cost. For smaller, “do-it-yourself” weatherization projects such as installing door sweeps, pipe insulation, and caulking, Northern Utilities offers a $25 "Self Install" rebate. Customers should see the program web site for rebate forms and program details. Customers can learn how to improve the energy efficiency of their home and save money on energy bills with a Home Energy Assessment. Northern Utilities' Partners in Energy Program offers up to $150 toward an in-home energy assessment. This program allows customers to pick their own contractor. Rebate forms and information on how to select a contractor can be found on the program web site. Northern Utilities, as a member of GasNetworks, also offers rebates for high efficient space and water heating equipment. This program offers residential customers up to $1,350 in rebates towards the installation of qualified high-efficiency gas-fired space and water heating equipment. Eligible equipment includes furnaces, boilers, water heaters, thermostats, and windows. All equipment must meet certain energy efficiency standards listed on the website. Customers fill out the application after the installation is complete. In addition, Northern Utilities is a sponsor of the state-wide Energy Star Homes Program, which provides various rebates and technical support for customers interested in building an Energy Star home.
