South Region Integration 

The creation of MISO’s South Region brought over 18,000 miles of transmission, ~50,000 megawatts of generation capacity, and ~30,000 MW of load into the MISO footprint.  MISO’s increased scale drives benefits through improved reliability and reduce regulation and spinning reserve requirements by consolidating balancing authorities and expanded options for generation commitment and dispatch from a more diverse set of fuel types.

Readiness Dashboards

Readiness dashboards were updated monthly to monitor the South Region integration process:

  • An entity readiness dashboard shows how the various entities in a jurisdiction are tracking against upcoming milestones.
  • A key milestone dashboard provides a high-level status update of the integration project schedule.
  • A program readiness dashboard evaluates MISO's internal business areas and programs against defined integration-related criteria including the ability to support the larger footprint after integration and confirmation that all customer impacts have been addressed.

Integration Activities

Transmission system integration into the MISO market requires the involvement of many parties including transmission and generation owners, load serving entities, power marketers, and adjacent balancing authorities.

Timelines, training materials and integration checklists aid the integration process for all entities joining the MISO market.
