The D.C. Circuit Court of Appeals vacated a FERC order allowing MISO to end reactive power compensation, though the decision has no bearing on the nationwide discontinuation of payments for reactive power in Order 904.

FERC approved MISO’s Transmission Owners’ request to eliminate reactive power compensation for generators, cutting a $220 million annual revenue requirement.

MISO transmission owners have filed with FERC to eliminate all reactive power and voltage control charges from their own and affiliated generation resources.
