Newman 5 Facts

Newman 5

Newman 5 is a “Combined Cycle” unit comprised of three separate turbine–generator units.

  • Two Gas Turbines and Generators
  • One Steam Turbine and Generator

The Turbines
Combined Cycle: 2 Gas Turbines and 1 Steam Turbine

  • Two General Electric Frame 7EA Gas Turbine – Generators
    • Megawatt (MW) Output:  70 MW each,  total 140 MW
    • Commercial Operation Date: May 2009
  • One Fuji Steam Turbine – Generator
    • Megawatt (MW) Ouptut:148 MW
    • Commercial Operation Date: April 2011
  • Total Newman 5 Output: 288 MW
  • Newman 5 Cost:  $234 Million

How it works
The heated exhaust gases from the two gas turbines go to the Heat Recovery System Generator to make steam that will drive the steam turbine generator for the combined cycle mode.  The new technology used in the Newman 5 unit will make it 35 percent more fuel efficient than existing units.
