Gov. Dannel P. Malloy signed an executive order Tuesday aimed at resolving hotly contested questions about the economic viability of the Millstone Power Station, a nuclear-powered generator of electricity crucial to Connecticut’s goals for reducing greenhouse gas emissions. An intense lobbying campaign by Dominion Energy, the owner of Millstone, failed to convince the Malloy administration or a majority of legislators over the past two legislative sessions that it needs more favorable rules governing the sale of electricity. Dominion was fought by consumer groups and competitors.
