Support is growing for Governor Gina Raimondo's plan to cut the commercial energy tax rate.  State officials say the most recent federal statistics show that only Hawaii has higher commercial electric rates.  Raimondo is proposing that the sales tax businesses pay for electricity, natural gas or heating be phased out over the next five years.  The state will lose around 26-million-dollars in annual revenue when the tax is completely phased out in 2020.
