On January 19, the Federal District Court in Brattleboro, Vt., issued a court decision in favor of Entergy Corporation, regarding the continued operation of its Vermont Yankee nuclear power plant. Entergy had sued the State of Vermont on several issues, but mainly on Act 160, a Vermont law that was crafted to block the continued operation of the plant. The plant needs a Certificate of Public Good (CPG) from the state in order to keep operating, but Act 160 says that the state's Public Service Board needs legislative approval before it could release its findings on the application for the CPG. Without the new CPG, the plant would have had to shut down when the original one expires, on March 21, 2012. The federal court's decision "permanently enjoined" the state from using Act 160 to deny a CPG to Entergy; the basis for that decision is the supremacy of federal law over state law.
