About

MISO-S1074 is a proposed 200 MW generation project located in Phillips County, Arkansas. The project, which utilizes an unspecified "Other" technology, is being developed by Entergy Arkansas, LLC. It is interconnected to the Ritchie Plant 230 kV Substation.

The project entered the MISO interconnection queue on February 28, 2025. It currently has an active status in the queue and is undergoing a System Impact Study (SIS). No proposed commercial operation date or interconnection agreement (IA) status is available.
