Transmission and distribution system operators are continually faced with the challenge of maximizing transmission capacity whilst balancing current security requirements due to fluctuating renewable energy revenues.

Knowing that the maximum current carrying capacity of an individual line can be increased by up to 50% on cool and windy days clearly shows the value in accessing accurate weather data.

Up until now the usual approach has been to find a near-by weather station that may be representative of the line or region in question but this often introduces considerable inaccuracies.

With Meteomatics, the necessary temperature and wind data can now be created for multiple points along a line, taking into account both height and topographical features. This makes it possible now to obtain accurate data along a circuit and at different altitudes.

Meteomatics scientific downscaling and calibration procedures, as well as convenient querying of points, lines and polygons via the Meteomatics Weather API, open up new possibilities for precision and improvement of overhead line monitoring.

By using the most appropriate Esri Weather Dashboard, which is part of the ArcGIS platform, this data can be clearly presented and monitored and by customizing and arranging the dashboard elements, the user is able to determine which data and alerts are most relevant to them. Intuitive use of the dashboard will allow users to accurately view individual data along a line at different time intervals.

The successful integration of Meteomatics' data quality and Esri's ArcGIS technology, with its convenient visualization and analysis capabilities, clearly creates significant value for network operators worldwide who use overhead line monitoring.
