Entergy Arkansas residential customers will soon be charged up to a dollar a month to help pay for home weatherization projects for poor families. The new fee will generate an estimated seven million dollars a year, with about 70 percent going to the project. Thirty percent will fund grants or loans for alternative fuels research and projects. The Legislature last year passed a bill establishing the Arkansas Weatherization Assistance Fund and the state Alternative Fuels Fund. According to the bill, an electric or natural gas utility may choose to contribute to the funds and be assessed a fee of one-tenth of a cent per kilowatt hour sold to each residential customer -- but not to exceed one dollar per customer per month. So far, Entergy is the only utility that has begun assessing a fee to fund the programs.
