Dive Summary:
- High temperatures across the Northeast and Midwest caused the PJM Interconnection to break a record for peak power use in September on Tuesday, the grid operator reported. PJM met demand for 144,370 megawatts (MW), which pales in comparison to the 2012 September peak demand of 129,959 MW.
- Many power plants and transmission lines were out of commission for maintenance, Terry Boston, PJM CEO, noted. "Our only option to prevent a potential equipment overload and failures that would cause a much bigger interruption was to call for emergency relief in the form of controlled outages."
- PJM called for emergency forced outages in Indiana, Michigan, Ohio and Pennsylvania.

“Continued heat in some areas today will require load reductions through demand response, but PJM and its members are working to prevent additional emergency customer curtailments.”
