Products Wind Measurements

Wind energy has the unique characteristic of being an inexhaustible and free "fuel". Despite the fact that the raw material is inexhaustible, the individual properties remain crucial for the economic viability of a wind energy plant. The economic viability of a project producing electricity using wind depends critically on the available wind potential at the location of the project. During the initial stage of design and development of the plant, long-term characteristics of wind in the area of interest are virtually unknown or almost unknown since there is usually only an initial wind assessment available from public and private sources, but is inadequate to meet the information needs of ISOs, wind farm operators and developers, power traders, resource analysts and government. These data sources are designed for aviation and consumer weather markets. They do not meet the need for actual wind speed data at the hub height and above the boundary layer of 80 meters. Usually, surface data from 30 or 40meter towers within the project boundaries is used to "guesstimate" UP to the hub height of today's utility scale wind turbines. Or satellite data is used to project DOWN to land based wind farm projects. Both are inaccurate and inadequate to meet investor due diligence and to support wind power integration into the grid.
Recent studies show that a slight increase in the mean long term wind speed brings about a multiplied increase in energy output. As the cost of capital is not heavily dependent on the wind speed, the change of the economic project in relation to the wind speed is very clear.
According to the above, it’s clear the importance of an accurate determination of wind potential in the region of interest.
The change of energy output relative to the wind speed varies depending on the wind speed. For areas with low speeds, the sensitivity change is greater than in regions with high speeds. For example, in a low wind power range the variation of wind speed may cause a fold change in energy production. This is certainly a simplified approximation of the conditions prevailing in a wind energy plant which do not take into account the specifications of the wind turbines and other factors. However they clearly describe the importance of wind speed measurements.

GaiaComm with years of experience in wind resource assessments provides complete solutions tailored to the nature and design of each wind power plant even above the boundary layer of 80 meters.
