MISO’s proposal to allow merchant HVDC lines to connect to its system is incomplete, FERC informed the RTO in a deficiency letter.

MISO and its stakeholders have agreed on a plan to treat merchant HVDC lines as transmission instead of generation.

MISO will submit two filings with FERC to further refine its new generation interconnection process, while a third will facilitate HVDC interconnection.

Despite not having any of its projects constructed, Clean Line Energy Partners, and CEO Mike Skelly, remain optimistic.
