MISO-J1897 is a proposed solar and battery storage hybrid development project located in Mississippi County, Arkansas. The project has a total capacity of 500 MW. Its listed component is a 500 MW solar facility, and a battery storage element is included as part of the hybrid configuration. The project is located within the service territory of Entergy Arkansas. It would interconnect at the Dell EHV – San Souci 500.0 kV point of interconnection.
The project is in the Midcontinent Independent System Operator (MISO) interconnection queue, which it entered on December 14, 2021, and its status is active. It is being studied in the DPP-2021 South study cycle and has requested Network Resource Interconnection Service (NRIS). The proposed commercial operation date was August 15, 2024. The interconnection agreement (IA) is listed as pending, with an associated IA date of December 8, 2025.
