The US Department of Justice (DOJ) and the Federal Energy Regulatory Commission (FERC) filed a joint brief on May 29 in the US Court of Appeals for the Seventh Circuit, stating that Illinois’ zero emission credit (ZEC) program for eligible nuclear plants in Illinois is not preempted by the Federal Power Act (FPA). Because the panel in a substantially similar case pending in the Second Circuit has indicated that it would review the government’s filing in the Seventh Circuit case, the views of FERC and DOJ could be critical as this issue plays out in the federal court system.
The Illinois legislature passed a law in 2016 requiring utilities to purchase ZECs at administratively set prices from nuclear plants in the state. Generators that compete with the ZEC-receiving nuclear plants challenged the law, arguing that the ZEC program is preempted by the FPA. The district court upheld the program, and the generators appealed the decision to the Seventh Circuit. FERC did not take a position in the trial court but has now done so after the Seventh Circuit invited the US government to file a brief.
