MISO South regulators publicly opposed a postage stamp cost allocation design, potentially setting the stage for a showdown as MISO prepares for a third long-range transmission portfolio.

MISO’s IMM debuted five new recommendations as part of his annual State of the Market Report, as multiple suggestions were aimed at maximizing transmission utilization by clamping down on wind-related congestion.

The clean energy organizer for the Alliance for Affordable Energy said there’s a lack of accessibility within MISO for individual ratepayers to make their opinions heard on grid decisions that affect them.

MISO said it’s on track this year to map out the new transmission lines it will require under the second portfolio of its long-range transmission plan to keep the grid stable.

MISO is developing possible project alternatives for the most expensive projects proposed this year in the South region under MTEP 23.

Faced with an exponential rise in interconnection requests, MISO announced that it’s aiming to make its queue a more exclusive club through new rules.

MISO has chosen LS Power’s Republic Transmission to build the first competitive project emerging from the RTO’s long-range transmission plan.

MISO laid out why it needs a 2nd LRTP portfolio, saying it will connect hundreds of gigawatts of new resources in the next 20 years to avoid reliability crises.
