MISO and PJM will not take on customary interregional planning studies this year, deciding they have enough on their plates with a new and in-progress joint transfer study.

Authors of a new report say better market integration and reduced interregional constraints in the U.S. transmission network would have saved as much as $12 billion in 2022 and 2023.

MISO and SPP staff asked for input on a joint system study in 2025 during their annual transmission issues evaluation with their Interregional Planning Stakeholder Advisory Committee, which was only too happy to comply.

MISO and SPP staff told stakeholders that they will not perform a Coordinated System Plan in 2025 but will accept transmission issues for their annual review early in the year.

NERC filed the completed Interregional Transfer Capability Study to FERC ahead of the December deadline set by Congress in the Fiscal Responsibility Act of 2023.

FERC approved tariff revisions and modifications to the joint operating agreement between MISO and SPP that will enshrine a structural and cost-allocation framework for the five projects in their Joint Targeted Interconnection Queue portfolio.

FERC Commissioner David Rosner talked about his hope for more consensus on rehearing for Order 1920, and a panel of experts discussed supply chain issues at the WIRES fall meeting.

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.
