Harry Allen GT
Location: NV
Operator: NV Energy
Configuration: 2 X 72 MW 7001EA gas turbines
Operation: 1995-2005
Fuel: natural gas
T/G supplier: GE
EPC: UE&C, Lockwood Greene
Quick facts: The Harry Allen site is about 25mi northeast of Las Vegas. It was originally to be developed as a 2-GW coal-fired power plant. Later the property was repurposed for eight simple-cycle GTs, of which the first two were installed, and then for continued build out with CCGT capacity. Unit-1 had one of GE's first, third-generation DLN1 systems, which were designed to achieve 9 ppm NOx while the second GT was among the first 7EAs in the nation to have a sub-5-ppm NOx DLN1+ system.
