What is good offshore wind potential?

Regions with annual average 100-meter height wind speeds of greater than 7 meters/second are considered as technically viable (for the current performance characteristics of offshore wind turbines)

What is LiDAR offshore wind?

Light Detection and Ranging improve wind energy efficiency Technology and services are developed and demonstrated to use LiDAR (Light Detection And Ranging) systems in offshore wind power plants to significantly reduce the cost of energy.

What is the capacity factor of offshore wind?

40%-50%
Offshore wind is in a category of its own, as the only variable baseload power generation technology. New offshore wind projects have capacity factors of 40%-50%, as larger turbines and other technology improvements are helping to make the most of available wind resources.

How is offshore wind measured?

“In recent years LiDAR has been deployed reliably on floating buoys to measure the wind profile of offshore areas. An upward facing laser is focused at select heights and can measure wind speed characteristics up to 250 metres above the instrument.

How many homes can offshore wind power?

A 1.5 MW turbine produces about 360,000 kWh per month. That’s enough to power 415 American homes and over 1,100 households in Europe. That’s at the small end of the scale. Offshore turbines with capacities upwards of 5 MW can power a few thousand homes at once.

What is sodar and lidar?

Sodar systems are like radar (radio detection and ranging) and lidar (light radar) systems except that sound waves rather than radio or lightwaves are used for detection. Other names used for sodar systems include sounder, echosounder and acoustic radar.

How does lidar work wind speed?

The Lidar anemometer is based on the Doppler effect. It measures the Doppler shift of radiation scattered by natural aerosols carried by the wind. It can measure wind speed and direction at several heights using a ground-based instrument.

What is the difference between load factor and capacity factor?

Load Factor, also called Capacity Factor, for a given period, is the ratio of the energy which the power reactor unit has produced over that period divided by the energy it would have produced at its reference power capacity over that period. Reference energy generation (net) is the energy that…

How do you identify wind resources?

Site-specific measurements using anemometers are considered by some to be the most reliable estimates of the wind resources for a project….2. Detailed Site Characterization

  1. anemometers and wind direction vanes, which are sensors to measure the wind speed and direction,
  2. a data logger, and.
  3. a meteorological mast, or tower.

How is wind resource measured?

Wind speed can be measured remotely using instruments on the ground and mounted on airplanes or satellites. Sensors on the ground or on airplanes use Light Detection and Ranging (LiDAR) technology to measure the wind speed and direction.
