US energy regulators back Illinois legislation

US energy regulators back Illinois legislation: The US Department of Justice (DOJ) and the Federal Energy Regulatory Commission (FERC) have submitted a statement to a court of appeal saying federal rules do not pre-empt Illinois' zero emission credit (ZEC) programme. The court is hearing an appeal against an earlier ruling that dismissed a lawsuit aimed at invalidating the programme, which provides financial support to Exelon's Quad Cities and Clinton nuclear power plants.
