SPP-GEN-2018-064 is a proposed 80 MW solar generation project located in Benton County, Arkansas. The development project is listed in the interconnection queue of the Southwest Power Pool (SPP), with the Grand River Dam Authority (GRDA) identified as the associated utility. The project would connect to the grid at the Tonnece Substation 69kV point of interconnection. No developer or project name is identified in the available queue data.
The project entered the SPP queue on October 24, 2018, and remains active. It was studied as part of the DISIS-2018-002 cluster within the 04 Southeast study group, and has requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS). An interconnection agreement (IA) has been executed for the project, an advanced milestone in the interconnection process. The proposed commercial operation date is July 11, 2027.
