SPP-GEN-2021-103 is a proposed 150 MW battery energy storage development project located in Johnson County, Kansas. The standalone storage project consists of a single battery component rated at 150 MW. It is planned to interconnect at Evergy's Atlantic Substation 115 kV bus, within the service territory of the transmitting utility identified as WERE. No developer or project name has been publicly identified in the available queue data.
The project is listed in the Southwest Power Pool (SPP) interconnection queue, which it entered on May 25, 2021, and currently holds active status. It requested both Network Resource Interconnection Service (NRIS) and Energy Resource Interconnection Service (ERIS). The project was studied as part of the DISIS-2021-001 cluster within the 03 Central study group. An interconnection agreement (IA) has been executed for the project, and its proposed commercial operation date is March 31, 2030.
