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 said it will salvage two to-do items from its effort a few years ago to better link up interconnection trends with annual transmission planning.

Presenters at a special two-day meeting of the Planning Advisory Committee advised MISO to consider recommending 765 kV and HVDC transmission lines.

MISO released details about how it will administer cost allocation on the $1 billion Joint Targeted Interconnection Queue portfolio of 345 kV projects.

MISO announced that it will add an informational study on near-term transmission congestion to its 2023 cycle of transmission planning.

MISO fired up the second phase of its long-range transmission planning by debuting a theoretical map of projects that proved divisive with stakeholders.

Clean energy and consumer advocates questioned whether MISO planners are sufficiently exploring alternatives to the projects its transmission owners submit.

MISO members are voting whether to recommend MISO’s $10 billion long-range transmission buildout to the RTO’s board as staff make final pitches for the project.

Faced with a capacity supply shortage in 2022/23, MISO is considering broadening its generator retirement studies to consider resource adequacy.

Clean Grid Alliance asked MISO to develop a means to see late-stage projects through its generator interconnection queue when they’re delayed.
