MISO and PJM, two regional transmission system operators (RTOs) announced that they will collaborate on an informational interregional transfer capability study, set to be performed during the second half of 2024.
Driven by input received by each organisation from the Organization of PJM States (OPSI), the Organization of MISO States (OMS) and the Midwestern Governors Association (MGA), the study will aim to identify potential opportunities for near-term transmission enhancements along the seam shared by PJM and MISO.
Increasing transfer capability between regions may help to support greater grid resilience, the organisations said, particularly following extreme weather events and the influx of renewable generation resources with intermittent output.
“MISO and PJM have a long history of working together to address operational and planning challenges in our regions,” said Aubrey Johnson, vice president System Planning and Competitive Transmission at MISO.

Europe’s grid is receiving record levels of investment. But is it enough?
“As we continue to focus on our Reliability Imperative efforts, we understand the need to explore interregional planning, and with encouragement from OPSI, OMS and MGA, we will conduct a study that will address both near-term needs and create a model for future studies.”
Specifically, the two RTOs will work together to explore opportunities to engage in joint transmission analysis and coordinated modeling, and leverage planning processes to promote reliability and resiliency through holistic transmission planning for ratepayers
After the study’s conclusion in early 2025, both grid operators will share their findings with the Interregional Planning Stakeholder Advisory Committee, an organisation established by PJM and MISO to review coordinated system planning activities with all stakeholder groups.
