Hybrid Wind Turbines Can Generate Power Even When the Wind Isn't Blowing

hybridwind

A Colorado company is introducing a system that will allow wind turbines to generate power even when the wind is not blowing. The SmartGen hybrid gas-wind turbine enables wind turbines to produce energy at periods of low wind, by turning the generic levitra canadian healthcare turbine with compressed air generated at the base of the tower from a turbo-compressor that is run on natural gas or biogas.

Even more importantly, the SmartGen system can be retrofitted into existing wind turbines, allowing existing facilities to increase their performance. This is cheap quality cialis likely to be particularly compelling for installations seeking to extend their production while remaining free of fossil fuels. In areas where biogas production is also available nearby, a wind power facility that is generating renewable energy credits could likely also produce power from biogas in this manner as another form of renewable power and www.breinweb.nl thereby remain 100% renewable energy based.

A smart clutch disengages the wind blades from the machinery when the compressor is engaged. The company also notes that the exhausted air from the air motor cools dramatically when it is released, which can help provide cooling for the generator nacelle and may even help prevent fires in the viagra australia housing.

"Large wind turbines, even in good wind resource areas, typically generate rated power only 30% of the time because the wind blows intermittently or at a low wind velocity," according to the company. Utilizing other fuels to keep the turbines generating power means that the system better employs the investment in equipment, instead of having it sit idle for much of cialis no prescription canada the time.

First Test of Wind-to-Battery Storage Is a Success

windbattery

Xcel Energy has been testing the first grid-scale battery storage system in the United States at an 11-megawatt wind farm in western Minnesota. The company's recently released interim report (PDF) indicates that this type of storage can be useful to the Smart Grid and can aid in the deployment of wind power.

The one megawatt sodium-sulfur battery has been undergoing testing since 2008 near Sioux Falls SD. The final report will be complete in 2011, following the next phase of testing which will examine "the potential value of the various battery system functions and determine the http://www.artscayman.org/discount-cialis-cialis potential cost effectiveness of the technology." Xcel considers this to be a small-scale demonstration project that will help determine its strategy for future deployment of "proven technologies that meet or exceed cost, reliability, and environmental requirements."

Several different issues were being tested with the battery installation including the effectiveness of shifting wind generated energy from off-peak to on-peak availability, balancing the variability of order cialis in united states wind generated power, and responding to real-time imbalances between generation and load. All of these traits are important for the expanded and efficient use of wind power.

 

Rhode Island Utility Commission Approves Block Island Wind Farm

block-island-wind
The Rhode Island Public Utilities Commission has approved a power purchase plan for a wind farm off the coast of Block Island, clearing the way for more offshore wind in the U.S.

The commission has approved an agreement for National Grid, the state's largest utility, to purchase energy from the wind farm for 24.4 cents/kWh over 20 years.  The utility has also agreed to purchase half of the power produced by the much larger Cape Wind project, at a lower rate of 18.7 cents/kWh.

The Block Island wind farm will be an eight-turbine pilot project that will include a transmission cable to connect it to the island and the canadian online pharmacy viagra mainland.  The wind farm will provide most of the power for the island with excess power being fed to viagra prescription order the mainland grid.  The island has been relying on diesel generators for electricity, which are not only dirty, but expensive.  This new wind farm will greatly reduce the cost of electricity for island residents.

Construction will begin late this year and cialis now online completed in 2012.

After the Block Island project is installed, the state has plans for a larger, 100-turbine project in the Rhode Island Sound.

California Breaks Ground on http://lifeinabundance.org/5mg-viagra Nation's Largest Wind Farm

alta-wind
A huge 3-GW wind project planned for outside of www.turismoalcala.es Los Angeles has received a boost in funding and is now on track to be operational by next year.  The Alta Wind Energy Center will be the largest wind project in the country, capable of powering 600,000 Southern California homes.

Terra-Gen Power LLC, the company building the project consisting of five separate wind farms, just secured $1.2 billion in funding, which has kicked construction into high gear.  The project just broke ground today in the Mojave Desert foothills, just 75 miles north of Los Angeles.  The first phase, which will produce about 570 MW, should be up and running by next year, while the full project will be completed in about a decade.

Southern California Edison has already committed to 1,550 MW of electricity produced by the project over 25 years.  Just that slice of energy is twice the capacity of the largest existing wind farm, a 735-MW one in Texas.

New Approaches to Wind Power in Massive 10MW Turbine Design

AerogeneratorX

Although the the best place purchase of cialis technology seems settled, new wind power designs are still being developed, especially as engineers try to extend the generating capacity of turbines. The Aerogenerator X is a new 10 MW wind turbine designed for off-shore use combining the best of horizontal axis and vertical axis designs. The engineering firm Arup and architects Grimshaw developed the design (based on an earlier Grimshaw design from a couple years ago) on behalf of http://www.kachinwomen.com/levitra-en-gel www.street-level.org the British company Wind Power Limited.

The familiar, three-bladed, horizontal axis turbine is cheepest viagra a well established design, but increased stresses as the size of these turbines increases makes it difficult to enlarge them further. Because of the square-cube law, larger wind turbines produce exponentially more power, so there is an incentive to build larger and larger turbines. This led to viagra price the innovative design, inspired by the sycamore leaf.

Aerogenerator X has a very large swept area, like a horizontal axis turbine. The span of the turbine is 275 meters (over 900 feet). But the Aerogenerator X is also only half the height of an equivalent horizontal axis turbine. And like a vertical axis turbine, the generator and equipment are located at the base. Stresses on the the best site get cialis cheap blades are reduced in this configuration, making it easier to design and levitra generico build something of this size. This also makes maintenance much easier, especially for an offshore turbine.

Project partners also include Rolls-Royce, Shell, BP, EDF, EON, Caterpillar, and the UK government. The first full-scale versions of this turbine are expected to be completed by 2013 or 2014.
