SPP regulators agreed to keep up their collaboration with MISO regulators, saying the effort is pressuring the RTOs to resolve their seams issues.

The cost of MISO’s 2021 Transmission Expansion Plan is set to ring in substantially below last year’s spending level, the RTO said at a planning meeting.

MISO will ask FERC for more time to plan the complicated process of opening its markets to distributed energy resource aggregators, RTO officials said.

MISO said it will soon present proposals for reformulating its VoLL while its IMM once again urged the RTO to nearly triple the current value.

SPP staff and stakeholders have added an accelerated decarbonization future to the RTO’s 20-year long-term assessment.

MISO’s Advisory Committee said it will defer to MISO as the final arbiter over whether a new company or organization is entitled to join a certain sector.

Stakeholders told MISO to rework a proposal that allows the RTO to remove stakeholders and committee leadership in certain situations.

Peak demand was lower in December than in years past, MISO executives said during an informational forum.

MISO said it will approach SPP about improving the processes underpinning affected system studies in response to stakeholders’ persistent calls for change.

MISO will draw on its new planning futures to build the first set of models that could result in the long-term transmission plan’s first projects.
