21st Century Wind, Inc.
Vision
To become the leading utility sized Wind Turbine Generator (wtg) Original Equipment Manufacturer OEM serving moderate winds market segments. By hardening the blades leading edge and sealing the nacelle by using a water-cooled gearing-generator, 21st CW wtgs can be placed in deserts.
Opportunity
We have the proprietary technology, experienced management and manufacturing supply chain in place to fill the multi billion dollar needs of this underserved market segment. With about a 20,000,000 kilowatt- hour annual electric production at 7 1/2 meter per second average wind speed, fewer wtgs will be needed to meet demand, lowering investment and increasing ROI.
Value Propositions
21st Century Wind’s land based wtg generates 30 to 65% higher Annual Electric Production (AEP), per dollar invested, than others in moderate winds . The moderate length blade, lower overall weight, and sectioned conical tower with reduced foundation cost – all combine to reduce installation cost by about 15%.
21st Century Wind’s Under Served Market Niche
The under served moderate wind markets East of the Mississippi River and West of the Rocky Mountains require affordable wind energy. A new, innovative wtg is needed to serve these moderate wind locations.
Wind turbines to serve this market must be suitable for siting on ridges.
These high energy usage and population density locales, with high energy prices and high desire for renewable clean energy, create a multi billion per year market segment. By hardening 21st CW for sandy environments, these wtgs can be reliably installed in moderate wind deserts
No current domestic or international OEMs now provide a cost justifiable turbine to serve this market segment.
21st Century Wind Solution to Under Served Market
Solution
21st CW’s affordable wind turbine unique for moderate winds. Ideal for ridge locations; 30 to 65% higher AEP per dollar invested. A utility’s Power Purchase Agreement has been received for electricity from 21st CW’s initial wtg.
3 + MW nominal output
The high output permanent magnet generator coupled with high efficiency gearing converts the blades’ high power coefficient into substantially more electricity in low and moderate winds.
3 bladed horizontal axis
Integrated 2 speed Gearing and Generator reduces weight, this combined with location of the power conditioning equipment to the ground reduces over all tower top weight and complexity significantly.
120m rotor diameter
Rotor has a higher specific power than a rotor of greater diameter, this means more power is extracted from a given column enabling shorter blades, easier manufacturing and transportation.
80m 120m hub height
By employing a rotor with greater specific power means, the tower does not have to be taller to perform at low wind sites, reduced weight allows for a potential service height of 140+ Meters
21st Century Wind team and product capabilities
21st CW is a team of dedicated and passionate wind energy experts with a wealth of expertise ranging from new turbine design, production, fleet reliability management and innovative product upgrades.
Supply chain companies are tier 1, providing key components per 21st CW specifications and drawings. For desert applications, the blades’ leading edges will be infused with metal to slash erosion, and the nacelle will be sealed as the gearing-generator is water-cooled versus air-cooled.
21st CW’s initial installation is expected to have a higher capacity factor than our peers and be less expensive to install. 21st CW’s energy is affordable; no new subsidies will be required to financially justify the purchase of our wind turbines.
All 21st CW wtgs include cold weather packages allowing operation to -20 degrees F. and survivability to -40 deg. F.
21st Century Wind’s Sectioned Tower
Tower can easily be transported onto ridges, increasing number of available sites that are near to energy consumers. Eliminates expensive and diameter limiting flanges between tower sections.

Low Disturbance Foundation
Larger base diameters result in a shallower footprint, requiring less earth works, less issues with run off, easier civil engineering
Larger base diameters result in greater stability at ground level which in turn results in less costly foundation designs the slab can be thinner and the piles produce very little encroachment
The foundation cap ensures load spreading in the upper region of the soil, and the piles transfer load to the deeper soil layers
