"The Supreme Court appeared to side Wednesday with energy industry groups in a case challenging the federal government’s authority to regulate electricity supply and demand.

At issue in the case — known as FERC v. the Electric Power Supply Association — is whether the Federal Energy Regulatory Commission overstepped when it imposed a rule requiring electric utilities to pay end users to cut their consumption when demand rises.
 
The Electric Power Supply Association and four other energy industry groups argued that FERC went too far and encroached on states’ exclusive authority to regulate the retail market."
