SPP Disappointed as MISO Axes Last Interregional Project

“MISO originally forecast that the 115-kV circuit project into Sioux Falls would have a 4.79 benefit-cost ratio. ” -RTO Insider August 22 Issue

This project was cancelled by MISO because they believe that a no-cost solution of having an open circuit is a long term fix for similar benefit. SPP has become increasingly angry with MISO over the outcome of these failed joint projects and studies. This lack of collaboration indicates no new transmission capability being added between MISO and SPP.
