The Michigan PSC wants FERC to force MISO to turn over a study used to identify areas that require the operation of system support resources (SSR) in the state’s Upper Peninsula.

FERC last week approved a new reliability standard that will allow PJM and other transmission planners to plan for “non-consequential” load loss following a single contingency.

PJM cut loads in IN, MI, OH and PA Tuesday as a 90-degree heat wave pushed loads to the highest ever for September, stressing the grid at a time when much generation and transmission was offline.
