Energy Trust of Oregon administers energy efficiency rebate programs for both residential and commercial customers of NW Natural in Washington. Energy Trust is awarding the rebates and providing resources and technical assistance to interested customers. To be eligible for the residential rebate program, customers must own a home in Washington and the home must primarily be heated with gas. A variety of energy efficiency improvements are eligible for rebates, including, insulation, windows, air and duct sealing, tankless water heaters, and furnaces. After completing weatherization measures (insulation and sealing), customers can receive a $100-$150 bonus cash incentive. With the exception of water heaters, floor and ceiling insulation, all equipment must be installed by an Energy Trust contractor or a Washington-licensed contractor.
