MISO-S1188 is a proposed generation development project in the interconnection queue of the Midcontinent Independent System Operator (MISO). The project's technology is listed as "Other," and its total capacity, developer, and county and state location are not specified in the available queue data. The proposed point of interconnection is the Rockdale 345 kV substation, and the transmission owner is American Transmission Company.
The project entered the MISO queue on June 11, 2026, and is listed with an active status. Its requested service type is designated as SIS. The proposed commercial operation date is August 19, 2026, about two months after the queue entry date. The available data do not report the status of an interconnection agreement, any link to an existing operating plant in U.S. Energy Information Administration records, or any news coverage of the project.

Composite operating-phase risk view — what this asset's risk profile would look like once it reaches commercial operation. Climate hazards across its operating life, expected generation variability, and offtake counterparty exposure, decomposed into a single decision-grade score. Powered by InfraRisk.
