MISO’s end-use customers called for more “insight and transparency into” the variance analysis as well as a lower, 10% threshold on cost overruns to trigger the analysis.

MISO said it doesn’t think it needs to step up cost monitoring on its ever-larger transmission projects as some stakeholders call for tighter measures.

MISO will examine one of the long-range transmission projects from its first portfolio following a cost increase of more than two and a half.
