MISO-S1105 is a proposed 300 MW battery storage project located in Lonoke County, Arkansas. The project is being developed within the Entergy Arkansas service area and has requested a System Impact Study (SIS). It entered the Midcontinent Independent System Operator (MISO) interconnection queue on June 24, 2025.
The project, listed as an active project in the MISO queue, is planned to connect to the grid at the KEO EHV point of interconnection.
