MISO-S1134 is a proposed 100 MW battery energy storage development project located in DeSoto County, Mississippi. The standalone storage project would interconnect to the transmission system at the Twinkletown point of interconnection, within the service territory of Entergy Mississippi, LLC. No developer has been publicly identified in the available queue data.
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on December 24, 2025, and currently holds an active status. It has been submitted under the SIS service type, and its proposed commercial operation date is January 3, 2028. The available data does not indicate that an interconnection agreement has been executed.
