Our public process for the Northern Missouri Grid Transformation Program allowed careful consideration of feedback from landowners, community members, interested agencies and local officials throughout the routing process. On July 16, 2024, Phase 1 proposed routes were selected and filed with the Missouri Public Service Commission (Mo PSC) for both the FDIM and MMRX Projects. On December 11, 2024, ATXI submitted an application to the Mo PSC for Phase 2 (DZTM Project). As part of the DZTM application, ATXI submitted route options that include the MISO Selected Single Circuit Option or the Double Circuit Design along with a summary of public feedback and stakeholder input. All Program routes are not final and are subject to final approval by the Mo PSC.
The expected timing for decisions from the Mo PSC is by the end of 2025. For information on the Northern Missouri Grid Transformation Phase 1 (FDIM and MMRX) filing, visit the Mo PSC docket website at Docket Sheet - EA-2024-0302 - EFIS. For information on Phase 2 (DZTM) filing, visit Docket Sheet - EA-2025-0087 - EFIS.
