State regulators working to improve MISO-SPP interregional planning processes and seams issues drew interested onlookers to their latest committee meeting.

Stakeholders at the Organization of MISO States’ annual meeting debated the merits of interregional transmission planning between MISO and SPP.

MISO executives and some of its state regulators provided sharply contrasting visions of the grid’s move away from fossil fuels and toward renewables.

The outgoing president of the Organization of MISO States used his final address to once again press the RTO to develop a long-term transmission plan.

SPP members moved to eliminate Z2 revenue credits for sponsored transmission upgrades, the source of years of stakeholder frustrations and jokes.

MISO officials signaled their willingness to entertain a request by state regulators to develop another long-term transmission package.

MISO is home to more than 4.5 GW of unregistered distributed energy resources, much of it for nonresidential use, the Organization of MISO States estimates.

The MISO Board of Directors’ Markets Committee agreed to fund the RTO’s share of its seams coordination analysis with SPP.

SPP’s Regional State Committee endorsed a report on wind-rich areas and several recommendations related to the effort to improve its planning processes.

MISO and SPP regulators are considering an analysis of the interregional planning process to supplement the seams coordination analysis already underway.
