WindForces is pleased to announce that it is now offering wind energy forecasting services to wind farm operators, energy traders, and grid operators, based on its cutting-edge atmospheric simulation technology. Dr. James Stalker, WindForces CEO, and chief technology architect, said this technology has been developed and perfected over a decade at his atmospheric R&D company, RESPR (www.respr.com).
WindForces wind forecasting system utilizes all available weather data sets around a wind farm and measurements specifically collected at the wind farm and its proprietary atmospheric simulation techniques and its own in-house supercomputing resources to deliver highly accurate and physically consistent wind energy forecasts. WindForces will deliver wind energy forecasts within the short-term forecast horizons (1-hour to several days for wind farm operational management) and within the long-term forecast horizons (9+ months for long-range planning). When it comes to wind forecasting, short-cuts and statistical approaches may produce forecasts that are useful in some instances but they won’t have the consistency required for capturing, for example, ramp events. Stalker said, one has to deal with the atmosphere, in its full complexity, to be successful in producing consistently accurate wind forecasts. Any other way, other than dealing with that complexity, will face failure, he stated.
Dr. Stalker said, all the available data, including site measurements, unfortunately, often amount to less than 10% of the required data for capturing this atmospheric complexity. These data limitations have been ascertained from his decade-long research efforts at RESPR, he said. Forecasting methods that rely on these limited data and statistics tend to struggle to produce accurate wind forecasts consistently. WindForces, on the other hand, is all about filling these huge data gaps with physically consistent data produced from all the relevant atmospheric processes, before attempting to produce consistent and accurate wind forecasts for each wind farm, he said. In other words, Stalker said, a 10% data set addresses only a 10% of the atmospheric complexity. Can anyone afford to ignore a whopping 90% of the atmospheric complexity, he rhetorically asks? Without employing these cutting-edge forecasts, one is effectively diminishing their revenue and, at the same time, increasing their operating costs. And, that will doubly hurt the bottom line, Stalker said.
WindForces has delivered wind information for wind resource assessment for its global clients over the past several years. WindForces provides site specific (locations/heights) and time specific (a few months to 30+ years) wind information anywhere in the world, within days to a few months. These data are being used for wind farm site selection, wind farm design and optimization, and now for wind farm operational management via wind forecasting services.

WindForces successfully tested a data output format compatible with a popular wind analysis software package called Windographer. With this latest important product development effort, users of Windographer can now readily obtain our highly accurate wind information and start analyzing prospective wind farm sites for viability/profitability in a matter of weeks–not months to years. Additionally, more advanced analysis, for example, for the purposes of wind turbine micrositing, can also be accomplished based on our wind information as Windographer allows the user to convert our data format to other native formats (e.g., MeteoDyn, WindSim, etc.). Contact us for more details about how you can take advantage of this newest benefit WindForces is offering and to obtain a sample WindForces wind information output file.
Additional benefits such as long period (10+ years) WindForces time series wind information, to be used for long-term wind energy projections without having to resort to the usual statistical manipulations, are being evaulated within Windographer by Tom Lambert of Windographer and James Stalker of WindForces. Stay tuned for further details on the latter development efforts.

WindForces, a high-tech company that provides wind energy assessment services to its customers worldwide, participated in a 2-day workshop on wind resource assessment. This event was sponsored by the American Wind Energy Association.
WindForces’ founder and chief technology developer, Dr. James Stalker, attended many of the presentations at the workshop and made the observation and pointed to the presenters and the audience that a critical piece of the puzzle was missing. According to Dr. Stalker, wind measurements made at one or two locations, followed by a whole lot of horizontal, vertical, and temporal extrapolations will not resolve the bias problem the industry has been struggling to address. Dr. Stalker believes that this type of bias is due to the fact that such extrapolations do not consider any physically valid and consistent basis and are usually based on ad hoc assumptions. He believes that the basis for these extrapolations lies in the dynamic atmospheric processes (“wind forces”).
Dr. Stalker discussed the above issue in more detail in his recent article. You can find this article at www.wind-energy-assessment.com/news/.
Through more articles and technical presentations, Dr. James Stalker will be looking forward to elaborating on this critical aspect of wind energy assessment until the fundamental limitations of current approaches are fully recognized by the global wind energy community.
