HARTFORD — Rep. Dan Carter was among the state legislators who turned out for a morning news conference held over concern about a proposed bill that seeks to get more than $300 million in taxes from the owner of the Millstone Power Station. Carter, a member of the legislature’s Energy and Technology Committee, has a been an outspoken critic of the proposal. Carter contends the plan unfairly targets Dominion, which owns the Millstone nuclear tax. What’s more, the proposal furthers the notion that Connecticut’s legislature is unfriendly to businesses. Dominion representatives say they’ll shut down one or both of their operating reactors in Connecticut if the tax is approved, a move the manager of the region’s wholesale electric market said would affect ratepayers throughout the state.
