MISO-J2190 is a proposed hybrid solar and battery storage development project in Mississippi County, Arkansas. The project has a total capacity of 500 MW, and the listed solar component accounts for 500 MW. The data also identifies a battery storage element, but no separate capacity is specified for it. The project is located within the service territory of Entergy Arkansas. It would connect to the grid at the Dell EHV – San Souci 500 kV point of interconnection.
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on August 24, 2021, and remains in active status. It is being studied in the DPP-2021 South study cycle and has requested Network Resource Interconnection Service (NRIS). Its interconnection agreement (IA) status is listed as pending, with an associated IA date of December 10, 2025. The proposed commercial operation date was August 15, 2024, a date that has already passed while the project remains under study.
