The windmills or wind turbines in eastern Washington are owned by EDP renewables.
The wind farm was developed by Horizon Wind (formerly owned by Goldman Sachs, later sold to EDP) EDP Renewables, a subsidiary of Energias de Portugal S.A. (
EDP), a Portuguese utility company and built by Puget Sound Energy (PSE), an electric and gas distribution utility in the State of Washington.
Small Wind Turbines for home use cost from $150.00 to $500.00 or so depending on the size of the wind turbine.
Large Commercial wind turbines that electric utility companies use costs around $1 million dollars each just for the wind turbine and then there's additional costs for the installation.
Commercial wind turbines are very expensive for both the wind turbine and the installation cost of the wind turbine.
Purchasing and installing a commercial wind turbine can cost over $1 million dollars just for one wind turbine.
The commercial wind turbines that the electric utility companies use costs around $1.5 million dollars which includes the wind turbine and installation costs.
Installing a commercial wind turbine that produces megawatts of electricity is no easy tasks and requires cranes and professionals to climb the tower to get to the wind turbine and install it.
A 10KW wind turbine costs between $30,000.00 to $40,000.00 and an average cost for the wind turbine and installation of the 10 KW wind turbine for the wind turbine and installation is between $48,000.00 to $65,000.00
A single large utility size wind turbine can produce around 1.5 megawatts of electricity and 7 of those large wind turbines can produce as much as 7.5 megawatts which is enough electricity to power around 2,500 homes.
Small residential turbines produce between 400 watts to 20 kilowatts of electricity.
Small residential wind turbines generate between 400 watts to 20 kilowatts of electricity.
Usually the wind turbine is a 12 volt wind turbine or 24 volt turbine that charges batteries that are connected to inverters or an inverter which then converts the low voltage into 120 volts of electricity.
Depending on how much electricity you use and if you have enough space for the small wind turbine the small wind turbine could potentially power a house.
However for best results you need at least 3 wind turbines to power a house and the wind turbines should charge batteries and then you convert that battery power into 120 volts using inverters.
That way the power is stored when it's windy and then you have access to the power even when the wind is not blowing.
When combined with 3 or more units, the turbines are able to power a small household entirely.
Most homeowners aren't looking to set up a mini wind farm on their property however, so a network of turbines and solar panels is the way to go if you're planning on being entirely off-grid.
Small Wind Turbines produce DC usually but they can sometimes produce AC as well if it's the AC type of wind turbine.
Large commercial utility wind turbines produce AC voltage and then it's stepped up through transformers and then decreased in voltage again as it reaches the homes or businesses etc that it's providing electricity too.
For low maintenance and long life, wind turbines use AC machines; specifically, the synchronous, synchronous permanent magnet, or induction generators.
For what it's worth, the generator's variable frequency AC signal is typically rectified to DC before being converted back to fixed frequency AC.
A 12 volt DC wind turbine can charge a battery or batteries.
You can buy 12 volt wind turbines and wind generators for home use that will help charge your batteries that you can use for inverters or other uses.
I have a 12 volt wind turbine that I set up at my campsite to charge my campers batteries to run the inside of the camper and my inverter.
The wind turbine works great when the wind is blowing even just a little bit and it's a great backup to the solar panels i also have.
If you look on ebay you can find and buy 12 volt wind turbines and charge controllers that will allow you to charge 12 volt batteries.
Solar panels are also great to have as well so if the wind is not blowing then you can charge your batteries with the solar panels using the sun when the sun is shining.
12 volt generators work just like an alternator in your vehicle that charges your batteries in the car when the engine is running.
Except the wind powers the alternator in the wind turbine instead.
