In light of stressed-out supply chains and a bogged-down study process, MISO has agreed to re-evaluate its rules around commercial operation dates in its interconnection queue.

MISO says it will file in October to put stronger obligations and more monetary risk on queue entry to weed out speculative generation projects and take pressure off its overcrowded interconnection queue.

MISO stakeholders are trying to figure out what transmission service requirements the grid operator has in place for battery storage that charges from the grid.

MISO proposes megawatt limits on annual project proposals, tripled entry fees and escalating penalty charges in its quest to oust speculative projects and lighten its gridlocked interconnection queue.

MISO has shortened one of the 345-kV lines contained in its $2 billion Joint Targeted Interconnection Queue portfolio with SPP, which will lower costs.

MISO says it will add a study to its planning process early next year to identify transmission reliability issues caused by distributed energy resources.  

MISO appears set on restricting the interconnection requests it will accept and will present a straw proposal at the July 19 Planning Advisory Committee meeting.

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.
