The threshold was identified as an obstacle to transmission projects that could ease constraints along the PJM-MISO seam.

MISO and SPP concluded their first joint study process, saying the exercise was a valuable learning experience even though it failed to produce a single interregional project.

MISO said last week it is continuing discussions with SPP on one interregional project, despite earlier staff recommendations to not proceed.

News that MISO is reconsidering a market congestion project in Southern Indiana sparked renewed complaints from developers over the RTO’s transmission planning processes.

A list of joint transmission projects between MISO and SPP has been trimmed and sent further down the line toward possible board approval late this year.

MISO and PJM have again narrowed a list of “quick hit” flowgate projects with the potential to relieve market-to-market congestion.

FERC completed its initial review of all interregional transmission planning compliance filings required under Order 1000 on Thursday.

MISO and SPP are considering potential transmission upgrades under a joint model for identifying congested flowgates that could be relieved by economic projects.
