MISO variance analysis
Multiple transmission owners have questioned the need behind a suggestion that MISO work more checks into its process for reviewing troubled transmission projects.
MISO said it will create more public notices throughout its variance analysis, the process it uses to reassess transmission projects that experience cost increases or other obstacles.
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.
