I just signed a letter calling on U.S. Senator Ron Wyden and Congress to renew the vital tax credit for wind and other sources of renewable energy. The Production Tax Credit (PTC) helps wind energy compete with highly subsidized fossil fuel industries, attracts investors for new wind projects, fosters innovation and employs tens of thousands of Americans in the clean energy economy.
Because of wind energy’s growing success, dirty energy billionaires, like the Koch brothers, campaigned to kill the renewable energy credit program. Congress is at a crossroads.
Will they support policies and industries that increase carbon pollution, fueling climate-related disasters? Or will they take action to promote safe, clean energy that will allow us to stabilize the climate?
As incoming Chairman of the Finance Committee, Senator Wyden will play a major role in deciding which direction Congress goes.
Please join me in telling Senator Wyden to renew the renewable energy tax credit now: http://act.engagementlab.org/sign/wind-credit_Wyden/?referring_akid=.227975.zAnFDm&source=taf
By signing the letter, you will send a message the future of our kids and and the stability of our climate are priorities that deserve urgent attention. Thank you for taking action!
PLEASE SIGN THE PETITION via Climate Parents | Senator Wyden: Restore support for wind power!.
WINData’s “WINDataNOW! Technology” was developed under research support from John Deere Renewables, NaturEner and the US Department of Energy. WINDataNOW! is a 4G high-fidelity real-time met data technology leveraging OSIsoft PI for use by wind energy integrators, forecasters, developers and plant and system operators.
WINDataNOW’s core technology takes advantage of many industry standard pieces of equipment and combines them to deliver real-time meteorological data to users. Various meteorological tower configurations and instrument combinations are possible and vary by individual site characteristic and customer specifications. WINDataNOW can even add non- standard sensors as required to further characterize the wind flows of a prospective site.
While today’s site assessment technology relies on 10 minute average wind speed readings, the WINDataNOW technology records a much higher fidelity data set (usually second-by-second data). Legacy systems paint an even more incomplete picture of a site’s potential operations once that 10 minute average data is rolled into hourly, daily or monthly averages.
WINDataNOW’s technology gives users the flexibility to use their high fidelity data in any manner necessary. They can easily assess a site’s behavior and dynamics during seasonal, diurnal, or synoptic variations over long periods of time without sacrificing their source data quality.
In order to deliver higher fidelity data to customers, WINDataNOW uses quality instrumentation that can deliver a more exact representation of the wind speed information to the WINDataNOW data acquisition system. The system is able to communicate wirelessly to a central server and deliver near-real time data to customers.
Because WINDataNOW uses OSIsoft’s industry leading PI System as its data repository, most utility and operating companies can use their live met data at its full fidelity just like any other data source that feeds their on-site PI System. This enables wind experts to interact with their data in familiar tools such as Excel, or PI ProcessBook. Met data can also feed directly into forecasting provider models and can be used to support rapid refresh.
Meteorological “Met” Towers
WINDataNOW! SuperDuty® data collection towers are available for sale and installation throughout continental North America. WINDataNOW!® towers are manufactured using high strength galvanized steel and are available in heights of 20, 30, 40, 50 and 60-meters.
WINData® installs NRG NOW systems in 50M, 60M and 80M heights and offers Second Wind towers systems and instruments.
WINData® is a registered reseller, distributor and installer of Mega80 (formerly AAT – Groupe Ohmega) 60M, 67M and 80M Met Towers.
For Hub-height measurement WINData installs Sabre and Rohn guyed lattice towers and Self supporting SSV towers for heights of 65 to 110 meters (350 feet).
Wind and Climatological Sensors
Sensors are installed to measure wind speed, direction, temperature and barometric pressure at designated heights. Clients’ choice of industry standard sensors are available for purchase and installation.
Industry standard loggers available for met tower installations from WINDataNOW!®, NRG, Second Wind and Campbell Scientific.
WINData installation crews install turn-key met tower systems from 50 to 120 meters . WINData also offers professional services which include, meteorological (“met”) system array design, tower specification, project installation and data integration to support end user wind integration requirements and forecasting data services.
The most crucial step in the development of a potential wind site is the collection of accurate and verifiable wind speed and direction data as well as other meteorological parameters. WINData met towers and WINData professional installation services insure collection of “bankable” on-site wind data using guyed met towers in heights up to 100 meters. Each met tower system installation is planned, specified and supervised by company engineers in conjunction with our clients’ in-house specialists. On-going support is available throughout the entire data collection period.
WINData installs tilt-up met towers to each customer’s specification.Selecting the proper height is important and WINData will select the appropriate size and instrumentation for your site.Common heights include 20, 30, 40, 50, 60, and 80 meter towers.Taller, non tilt-up 100 meter towers are also available for either permanent or temporary installation.
WINData conducts wind resource assessments to determine the meteorological and climactic characteristics of a site and from this analysis can estimate the potential power production and the impact to the project’s bottom line.
WINData provides met program design, data collection, data summaries, wind power output summaries, wind site analysis and professional meteorological certified reporting as per client requirements. Preliminarily, WINData can often determine a site’s seasonality and wind quality through a combination of a site visit, maps, and any existing site or regional data.
WINData site analysis is conducted using wind speed, wind direction, temperature, pressure and regional air density data gathered at or near the site’s location. Typically, wind flows vary over the complex terrain in a project area and it is crucial to have an experienced analyst conduct a topographically appropriate site study.
WINData wind site assessments provide project owners and designers with:
The average wind speed over all the turbine locations for the project
The maximum mean wind speed at the turbine location
Mean Wind Speed
Weibull Parameters and
Other factors examined to determine the environmental conditions at the site include:
Annual average ambient temperature
Extreme minimum ambient temperature
Extreme maximum ambient temperature
Days of temperature below –17° C
Days of temperature above 30° C
Average relative humidity
Height above sea level
The Weibull scale parameter and mean wind speed are used to determine the IEC Classification of the site and the subsequent classes of turbines that are suitable. The lower Weibull shape parameter indicates a large mean wind speed. The air density at the site is lower than at sea level, which will reduce the fatigue caused by the large mean wind speed.
If the temperatures on-site are very low, Low Temperature Option package are required from the turbine manufacturer and will be necessary for the best performance of the wind turbines at the project site. WINData uses the met data analysis to determine the size, number and manufacturer of wind turbines that will be used.
For each turbine, the following information is considered:
Tower type and proposed hub height
Level of certification achieved
IEC design wind class (I, II or III)
Summary of performance guarantees and warranty provided
WINData can lead the process for final wind turbine selection and generate turbine recommendations for the project site. As the turbine selection process proceeds, WINData can go out to the list the potential turbine vendors to determine the availability and delivery schedule and other aspect of the turbine supply process, and further, obtain firm pricing bids and negotiate TSA’s and MRO’s for equipment and for warranty, service, and maintenance agreements with the manufacturer.
