Gamesa Introduces Improved Wind Turbine (Especially for Low-Wind Sites)
Gamesa has released a new wind turbine, model G114, that it claims has some considerable improvements over older models, such as:
- The best power density on the market: There are two units of power density — power-to-weight ratio (gravimetric energy density), and power-to-size ratio (volumetric energy density). Unfortunately, Gamesa didn’t state which power density unit it was referring to. If it was the former, that would mean that it is the most powerful turbine on the market of its weight. If it was the latter, then that would mean that it is the most powerful wind turbine on the market for its size.
- A maximized return on investment in low-wind areas, compared to its predecessors: This is a step that makes it financially feasible to install wind turbines in more low-wind areas than previously thought. Improvements like this mean that wind farms can operate economically in more locations than ever before. This is because low-wind sites are typically ignored because the cost to generate wind power is too high there, but this turbine will make it economically viable to use wind turbines in some of those areas.
The new wind turbine can generate 2 megawatts (MW) of electricity. It features a rotor which is 114 meters (374 feet) in diameter, with a swept area of 10,207 square meters. Each blade spans 55.5 meters (182 feet).
If wind turbines could generate electricity cheaply in the most stagnant of areas, then they could be used everywhere. This is a step in that direction.
