Frustration over the lack of transmission growth and interregional planning mixed with optimism over FERC’s recent rulemakings at the Transmission Summit.

The first meeting of the Mid-America Regulatory Conference in two years focused on transmission needs that are necessary for a fast-changing energy landscape.

Time is running out to build the infrastructure needed to meet climate challenges, transmission planners, generation developers and others warned.

MISO and SPP announced that they plan to ditch their current affected systems study process for more interregional transmission studies like their JTIQ study.

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