MISO-J3400 is a proposed generation project located in Deuel County, South Dakota, with a total capacity of 142.2 MW. The project, which utilizes an unspecified "Other" technology, is being developed within the Otter Tail Power Company service area. It is interconnected to the grid at the Astoria 345kV substation.
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on March 20, 2024, and has a proposed commercial operation date of April 19, 2028. As of the current data, the project's interconnection agreement (IA) status is not specified.
