After five fruitless attempts to agree on joint transmission projects across their seams, MISO and SPP will use what they call a “blended joint model” in parallel with existing SPP and MISO regional models.

MISO and PJM are deliberating whether to embark on an interregional transmission study this year as they field more calls from stakeholders to revamp their joint planning framework.

A bevy of consumer, clean energy and environmental advocates have joined state regulators in appealing to MISO and PJM to undertake more comprehensive interregional transmission planning.

MISO and SPP say this year’s coordinated system plan study will focus on “solutions to historical, persistent congestion issues” on the RTOs’ seam.

MISO and SPP said they will likely establish a smaller interregional project type, which could produce the two's first cross-border transmission project.

MISO, SPP won’t do a major interregional transmission study in 2021; they are focusing on a joint targeted interconnection queue study.

MISO and SPP have once again failed to identify any beneficial cross-border transmission projects after a fourth interregional study.

MISO’s and SPP’s market monitors presented their last report to state regulators working to improve the RTOs’ interregional coordination.

MISO and SPP appear to have come up empty once again after a fourth study failed to detect a joint transmission project.

SPP identified a couple potential joint projects with MISO but none with Associated Electric Cooperative Inc.
