NovelEdge™ Technology is a high power density combined cycle arrangement. With a 2-on-1 NovelEdge Technology arrangement utilizing two (2) "F" class gas turbines (GT's) and producing 950 MW, it is the highest power density of any combined cycle plant - and by a wide margin!

There are numerous advantages to NovelEdge™ Technology, and they are usually determined by the application. For the repowering of an existing 500 MW steam plant, conventional technology may require 4 "F" class GT's. Significant steam path modifications to the steam turbine (ST) may also be necessary. With NovelEdge™ Technology, only 2 "F" class GT's are required and little or no modifications to the existing ST are necessary. This provides obviously large capital and maintenance savings, but the surprising element is that the heat rate will be similar to or better than conventional repowering in many instances.

Similar comparisons are noted for Greenfield combined cycle power plants, where a NovelEdge™ Technology 3-on-1 application can produce 1200 MW, displacing 2 conventional blocks of a 2-on-1 arrangement (4 GT's and 2 ST's total). Again, the capital and maintenance savings are huge.

The itemized list below summarizes some of the advantages that can be realized from implementation of NovelEdge™ Technology. (For more detailed economic comparisons, please see our Economics page.)

Advantages of the Patented NovelEdge™ Technology:

 Initial Plant Capital Expenditure:
                • Up to a 25% reduction in initial plant capital costs ($/KW) for Greenfield applications.
                • Up to a 40% reduction in initial plant capital costs ($/KW) for repowering applications.


 Plant Revenue:
                • Up to a 80% increase in base plant output.

 Operating Costs:
                • Reduced financing costs as a result of lower initial plant capital costs.
                • Reduced fuel costs (dependent upon plant load duration curve)
                • Reduction in maintenance costs of major equipment.


 Permitting:
                • NOx levels comparable to current "state of the art" designs. Environmental concerns are diminished.

 Plant Operation:
                • Increased plant operating flexibility. (10 to 100% load in some cases)

 Space Saving:
                • High power density design allows for greater power output with less available real estate.
