Having agreed on a first potential interregional transmission project with MISO, SPP is moving the 115-kV line in South Dakota through regional review.

MISO and PJM are evaluating proposed interregional market efficiency projects, but a supplemental project by AEP could undermine most of the proposals.

A summary of news out of SPP's Seams Steering Committee and the MISO-SPP Interregional Planning Stakeholder Advisory Committee.

The first MISO-SPP interregional project inched closer to reality Thursday with a vote of confidence from the MISO Planning Advisory Committee.

Just one project from MISO and SPP’s coordinated system plan study will move forward for individual votes on regional review.

MISO and PJM will entertain proposals for interregional reliability projects even though none of the 19 planned reliability upgrades offer opportunities for collaboration.

Preliminary results of the MISO and SPP '16 coordinated system study are in, and the RTOs say one project has potential, but it fails MISO’s cost threshold.

The odds of SPP and MISO conducting a second joint study dropped as the RTOs’ reviews are not lining up. Plus the Z2 Task Force is narrowing alternatives.

Southwest Power Pool and MISO continue to study seven potential joint transmission projects across their seam. Next: developing the 2017 joint study.

The MISO and PJM targeted market efficiency project portfolio has dipped from seven projects to five.
