The primary objective of Interconnection Process Enhancement (IPE) 5.0 is to address commitments the ISO made during IPE 2023, where the ISO made foundational changes to its interconnection procedures, which were approved by FERC. The designation "5.0" reflects that this is the fifth iteration of the IPE initiative.
