Greentech Lead America:Â Solar Wind Energy Tower has managed to reduce capital costs and improve financial performance of the Downdraft Tower thanks to its innovative design and construction methods.
The Company recently announced the completion of weather data models that confirm the first tower height was lowered from 3,000 feet down to 2,250 feet. Reducing the Downdraft Tower’s height and shape enables the structure to be built much more affordably using the newest formulations of industrial concrete.
The newest concrete construction methods enable the concrete to be mixed at ground level and pumped to every level under construction and poured in place. This construction method is much faster than building pre-cast sections on the ground and transporting each section to the required level. The time to construct each tower is dramatically reduced along with the cost of construction.
For this development, the company has used their recently announced software which can calculate and predict energy production by our Solar Wind Downdraft Towers given local weather data. By feeding the weather data for southwestern Arizona/ Northern Mexico into the program, the Tower’s height and diameter was adjusted along with the amount of water added as fuel to create a desired amount of energy.
Solar Wind Energy can now evaluate potential Tower sites around the world and calculate and predict the shape and size of the Tower and the amount of electricity that can be produced in any region. Multiple Towers can be deployed in “Compounds” using the same cranes, water source, delivery, manufacturing and construction systems and labor forces.
Under the most recent design specifications, the first San Luis Tower is expected produce abundant, inexpensive electricity with a design capacity on an hourly basis, of up to 1,250 megawatt hours, gross. Using a 60 percent capacity factor, the Tower’s potential hourly yield equates to 600 megawatt hours, from which approximately 18.5 percent will be used to power its operations, yielding approximately 500 megawatt hours available for sale to the power grid.
Factoring in lower capacities during winter days, the average daily output for sale to the grid for the entire year is approximately 435 megawatt hours per day. Currently in California avoided costs are running approximately $0.11 per kilowatt hour. As an independent power producer of clean renewable energy, the Company will be selling power directly to the power grid rather than directly to consumers.
