What does compression have to do with wind power?
In an ideal scenario, wind power would be generated just like fossil-fuel power: first, it would be continuously available, around the clock and in every season; and second, power output could be increased or decreased in order to meet fluctuating demand.
Although there are some places where the wind is nearly constant, there is not a single location in the world where the wind can be controlled.
Compression enables us to capture the wind as it blows and control the power output, to produce more or less electricity according to demand - this is called dispatchability. With dispatchability, wind becomes a reliable source of clean, renewable, locally-fueled power.
Where can Dispatchable Wind Power Systems be used?
In a Dispatchable Wind Power System, compressed air is forced into a pipe, tank, or cavern and then released through an expander to generate power during periods of peak demand. In order for this process to be efficient, there must be at least moderate wind, and to maximize capacity, there must also be suitable geologic features to provide extended storage. Fortunately, these conditions are met in many locations throughout the developed world.
How significant is geologic storage to the efficiency of the overall system?
Geologic storage does not improve or degrade the efficiency of the system - it adds storage capacity at a low cost.
Good geologic features may result in both reduced storage costs and greater storage volume. Geologic storage may also boost capacity payments, enable the expanders to be upgraded to a higher power rating, and reduce the risk of extending long-distance transmission to a project.
What is the power rating of a Dispatchable Wind Turbine?
General Compression is developing its Dispatchable Wind Power System around a 1.5 MW turbine, visually indistinguishable from a conventional 1.5 MW turbine, and featuring similar foundations, towers, blades, and nacelles.
The key difference is that in the DWPS turbine, some of the heaviest and most expensive components in the nacelle - the generator and high ratio gear box - are replaced with a lighter compressor array and low ratio gear box.
Who will provide the warranties on the new turbine, compressors, and expanders?
General Compression will provide warranties on the system. Various vendors will warrant their components to General Compression. Our warranties will be supported by our industrial and financial partners.
Can Dispatchable Wind systems be installed in private homes?
Currently General Compression is focusing on commercial-scale Dispatchable Wind installations.
When will Dispatchable Wind power be available?
Component testing is already in progress, and the first prototypes will be erected in 2010. The first Dispatchable Wind System installations could come online in 2012.
