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

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.
