Values in RED indicate basins updated since previous statewide plan.
  1. MW = Megawatts
  2. The 33MW Osage Power Plant is assumed to be retired.
  3. These values assume dry cooling technology will be used.
  4. Basin Plan Update one new steam generation facility. Type and amount of generation was unspecified.
  5. Projections were completed to 2032, a 20-year projection rather than a 30-year projection.
