MISO-J1391 is a proposed 100 MW solar generation project located in Dubois County, Indiana. The development project is situated within the service territory of Southern Indiana Gas & Electric Company d/b/a Vectren Energy Delivery of Indiana, Inc., and is planned to interconnect to the grid at the Duff 138 kV Substation. The project consists of a single solar component with a capacity of 100 MW. No developer has been publicly identified in the available queue data.
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on April 29, 2019, and was studied as part of the DPP-2019 Central study cycle. It has requested Network Resource Interconnection Service (NRIS). The project's status in the queue is active, and an interconnection agreement (IA) was executed on June 25, 2025. The proposed commercial operation date listed in the queue is August 1, 2022, a date that preceded the execution of the interconnection agreement.
