What happened: For over a decade, the two grid operators have mulled over potential interregional transmission projects—and each year, the duo has stopped short of advancing any proposals. This year is no different.
Why? MISO and SPP were considering several projects to connect their Southern seam. They hoped these could boost reliability and curb congestion costs in both grids. But this week, the orgs said that none would pencil out.
The issue: The grid operators “understate the value of interregional transmission,” according to a Brattle Group report prepared for the Southern Renewable Energy Association. In fact, they may undervalue the cost savings of these projects by 2-3X, according to the report.
“The interregional planning process is broken, hurting the affordability and reliability of both regions,” the regional clean energy group wrote in a statement.
