This is unique, no other competing technology offers the same.
Minimum water use
17
Engine plants minimize not only fuel but alsowater consumption thereby providing majorenvironmental benefits. These plants use aclosed loop cooling system that requiresminimal water
Simple Cycle water consumption = 2 gal/engine/week
Low pressure gas
Engine power plants use low pressure natural gas (85 psig). No need for aux. gas compressor or high pressure gas line
