MISO is considering how to restrict generation developers’ ability to change the fuel type of proposed projects in the interconnection queue.

FERC said MISO’s Tariff was silent on the issue of whether a generation project can switch from wind to solar while in the RTO’s interconnection queue.

MISO must clear up language regarding surplus interconnection service and material modifications to comply with Order 845, FERC ruled.

FERC directed MISO to submit another Order 845 to clear up its process related to technological advancements, service requests and contingent facilities.

MISO plans to refile a revised version of a plan to speed up its current 500-day interconnection queue process after FERC rejected its first attempt.
