How can weather data support wind energy site selection and resource assessment?
Weather Data for Wind Energy

Turn wind weather data into better energy decisions
General forecasts do not provide the local, granular data that operators need to protect their operations. These weather overviews are meant for the general public and often do not include the specific conditions that affect individual wind turbines over time.
With specialized wind resource data, operators can plan site locations, predict wind power density, and quickly adjust to changing conditions that may threaten their assets. A consistent set of data from trustworthy resources ensures users don’t need to guess about wind performance at any point in time.

Key weather API features for wind energy
The Visual Crossing Weather API aggregates high-quality data from numerous national centers and government departments worldwide, including Met data, the US Department of Energy, the European Centre for Medium-Range Weather Forecasts, and the National Weather Service. This provides the spatial resolution researchers or operators need, whether they operate in the contiguous United States or across several countries worldwide.

Historical and forecast data
While minute-by-minute updates are crucial for daily operations, operators need quality time series for wind resource planning and performance analysis. Through understanding past wind patterns and future conditions, teams can make calculated decisions about site evaluation or energy forecasting. We offer over 50 years of data, cleaned and ready to analyze.

CSV and JSON Results
Our weather API provides several formats that can support a large number of different workflows. CSV is valuable for simple integration into operational planning tools or reporting workflows, while JSON offers the robust hierarchical structure necessary for deep engineering analysis.

Location address geocoding
While general forecasts provide overviews of large regions, location-address geocoding lets you see real-time conditions for specific wind sites, project areas, or locations under review for further development. This capability is crucial for project planning and site assessment, but also provides invaluable insights during daily operations.

Weather API or direct download
Teams can integrate the weather API directly into statistical analyses or interactive maps to access high-quality data at a glance. Downloading data is also simple, providing the robust datasets needed for long-term operational planning.
Solve your wind energy weather data challenges

Planning
A single turbine can cost hundreds of thousands of dollars, so teams need comprehensive data on average wind speeds, directions, and costs before making a final purchase decision.
Through our weather API, teams can evaluate the suitability of a given site using specific metrics and then compare wind conditions across several potential sites. This ensures the final investment decision isn’t based on a price tag and imagined potential, but on hard data.
Knowing the specific challenges of a site can also prevent costly missteps, like choosing the wrong turbine height or angling turbines toward dangerous shear winds. In certain areas, especially offshore wind farms, severe events like hurricanes or typhoons may cost operators thousands if not accounted for during site evaluation. Knowing historical extremes can help teams incorporate this into their contingency plans, ensuring everyone is ready to act when certain thresholds are crossed.
Construction
Wind and solar power sites are often in remote locations, meaning accurate weather data is essential to managing delivery risk and construction crew safety.
By assessing changing wind conditions, teams can schedule activities for safe windows. For example, they may delay setting up scaffolds and placing turbines until the wind is calm, as otherwise, crews may be placed in harm’s way. This reduces weather-driven disruptions and ensures that projects are delivered on time, without endangering human or technological assets.


Operations
Once a wind site is operational, weather data enables teams to plan day-to-day site activity. Operators can align performance expectations with actual or forecast conditions. During low-power days, grid planners can switch to other electricity generation methods and schedule planned maintenance, ensuring minimal disruption to consumers.
Turbines may be damaged by wind speeds or gusts above a certain threshold. With the Visual Crossing Weather API, operators can set parameters and receive advanced notice when conditions deteriorate, protecting these expensive assets without endangering the grid.
Analytics
When combined with other statistics, such as turbine sensor data, wind energy data helps operators get the most out of their assets. This data enables teams to review performance patterns and identify potential issues before the turbine fails. They can also refine their forecasting assumptions, such as recognizing that certain models do not align with more optimistic manufacturer projections, and adjust accordingly.
Lastly, weather data helps teams identify where sites or assets could be optimized, whether by adding new turbines or adjusting angles to capture more power.

FAQs about Weather Data for Wind Energy
Wind resource maps can guide teams when choosing the right site. For example, two sites next to one another may have significantly different wind speeds due to complex terrain features. Once a site has been developed, teams can analyze the operational data collected against real-world conditions to assess efficiency, plan updates, or decommission nonfunctional turbines.
Wind weather data typically needs wind speed, gust, and direction at several heights. The most standard metrics are 50m, 80m, and 100m.
Wind data enables teams to predict generation capacity for a given day based on wind patterns at turbine height. This can be used to determine potential output in comparison to demand.
Understanding current and future weather conditions helps teams plan maintenance activities around times when wind power is likely to be low. Additionally, knowing the current and future wind resource power is critical for grid stability, as it ensures that teams can offload loads to other assets or protect their assets by shutting off turbines during wind storms.
As wind farms can cost hundreds of thousands of dollars, optimizing for peak performance is crucial to long-term profitability. Historical weather data is valuable for wind energy generation because it helps teams assess the wind resource potential at a given site, ensuring the site is suitable for development. Teams can consider the overall energy needs of the area and plan for grid stability before investing.
Using historical weather data, teams can also predict future conditions, estimate potential output, and measure site performance against these benchmarks. This can reveal potential issues, such as low-performing turbines with mechanical problems.
Certain areas, such as around coasts or high-altitude farms, are prone to high winds that may damage equipment. Factoring this into calculations through historical wind highs can ensure that teams choose turbines rated for these conditions while also developing contingency plans for the worst-case scenario.
