Get step-by-step guidance for making a generator interconnection request and completing the application. Start by downloading these quick-reference documents.
Once you have submitted a complete application for generator interconnection, your request will enter MISO's queue. The queue process includes the following studies and analyses.
Within the DPP, there are three phases and two Decision Points; however, customers must provide M1 and M2 milestones and D1 and D2 study deposits at least 45 calendar days before the start of the next DPP. MISO will utilize reasonable efforts to complete the DPP System Impact study and the Facility studies in ~490 calendar days.
You may request an optional study to get sensitivity analysis and cost estimates for providing transmission service or interconnection service. The study will identify all of a transmission owner’s interconnection facilities, system protection facilities, distribution upgrades, generator upgrades, common-use upgrades and network upgrades.
MISO conducts optional studies in parallel with interconnection requests or on a stand-alone basis. To initiate an optional study, please provide MISO with:
You may request a Provisional Study for Interconnection Request submission through Interconnection Customer Decision Point II or at any time the Interconnection Facility Study for Network Upgrades becomes delayed by more than 60 calendar days. (see PGIA study application form)
MISO conducts Provisional Studies to offer conditional ERIS to the customer prior to the completion on the Network Upgrades.
