MISO-J1559 is a proposed 200 MW solar generation project located in Conway County, Arkansas. The development project would interconnect to the transmission system at the Morrilton East Substation on the 161 kV bus, within the service territory of Entergy Arkansas. No developer or project name is identified in the available queue data. The project consists of a single solar component with a capacity of 200 MW.
The project entered the Midcontinent Independent System Operator (MISO) interconnection queue on June 18, 2020, and was studied as part of the DPP-2020 South cycle. It requested Network Resource Interconnection Service (NRIS). The project's proposed commercial operation date was April 1, 2023. Its queue status is listed as active, and its interconnection agreement status is recorded as "Construction."
