  • Kyrene is a quick source of electricity. Unit 4 is a combustion turbine capable of producing power within 20-30 minutes; Units 4 and 6 are 'quick-start' turbines that can produce power in less than 10 minutes to add critical power to meet peak demands.
  • Kyrene increases the reliability of the local electric system.
