Duke Energy to Construct Its Fifth Wind Farm in Texas

September 24th, 2011 by  

Scroby Sands Wind Farm

For the second time this month, Duke Energy announced that it will construct a large-scale wind farm in Texas, United States.

Duke Energy Renewables will build, own, and operate the wind farm, which is to have an electricity generation capacity (nameplate capacity) of 202 MW (202,000 kW). This is titled the Los Vientos II Wind Power project and it is to sell its electricity and renewable energy credits to Austin Energy.

The nameplate capacity of a wind farm is the maximum amount of electricity that it can generate. This is not to be confused with the average amount of electricity that it generates.  The average amount of electricity generated is the most important figure because the cost of electricity from power plants is partially and heavily dependent on that.

The average amount of electricity that a wind farm generates is dependent on the average wind speed of the location that the wind farm is situated. In other words, the average amount of electricity generated by a wind farm is completely dependent on the geographic location of the farm. Whenever someone describes a wind farm as 300 MW for example, then that means it generates up to 300 MW, but it is not actually 300.

The company intends to commence construction of the wind farm in December. It intends to complete it and start operating it in 2012. This effort is part of a much larger one to add 770 MW (770 million watts) of wind farms by 2012.

As was the first Los Vientos project, this wind farm will be situated in Willacy County, which is 120 miles south of Corpus Christi, 20 miles inland from the Gulf of Mexico.

CPS Energy is to buy all of the electricity from the first phase of the project under the terms of a 25-year power purchase agreement.

    In the last few months Duke Energy brought new wind farm on line in Kansas and signed a long term contract to sell the power a <$0.035/kWh.

    That's some cheap electricity when one considers that wind gets only a small subsidy and doesn't have the much higher subsidies and hidden costs of nuclear and coal.

    A year or so earlier Duke put their plans to build a new reactor on hold and since have become very active in renewable energy. This, to me, is a good sign that we've turned a corner and renewables are on their way to becoming major industries.

    Like it or not, in order to get fossil fuel out of our lives it will take very large industries to do the job.

      Good points & additional info. I think it is clear, with more and more huge companies putting more of their money on clean, renewable energy (e.g. Siemens, GE, Duke Energy) that this is our future.

        It seems to be our best hope for having a future.

        After this year’s record melt of Arctic sea ice and the incredible floods, droughts, and heat waves it’s looking like time might be running out.

        Sure seems like we need to up our game by a massive amount and we need large corporations to put their resources and muscle into the effort.
