As turbines continue to grow taller, Lidar has emerged as a powerfull tool for collecting precise, bankable data at a range of heights. Ideal for wind resource assessment, wind turbine optimization, and wind plant monitoring, the Spidar Vertical profiler can be deployed alone or alongside a Met Mast, and can used in a variety of climates and terrains.
Pair Lidar with met towers at your prospective wind plant site to obtain economical, hub-height wind speed measurements.
The Spidar Vertical Profiler is a DNV GL Stage 2 remote sensing wind measurement device that uses Pulsed Direct Detect Lidar technology to provide bankable wind measurement data at 10 vertical heights.
This low-cost remote sensor is ideal for wind resource assessment, wind farm operations, forecasting, research, and meteorological applications. Spidar has the smallest cone angle of any remote sensor in the wind industry, so it can be sited closer to potential obstacles such as buildings or trees. It is also compact and highly portable. This allows Spidar to measure in locations where meteorological towers are not viable due to terrain complexity or permitting constraints.
Spidar is a complete remote sensing solution backed by NRG’s global partner network, technical support, remote power supplies and integrated services for seamless installation and operation. To date, over 150 Spidar Vertical Profilers have been delivered to dozens of wind energy and meteorology customers around the world.
Each Spidar is individually validated against a reference Spidar to confirm it performs to specification. The reference Spidar is routinely calibrated by a third party in compliance with IEC 61400-12-1 (Ed. 2, Annex L) using MEASNET-calibrated class one anemometers.
Spidar has been independently verified by several leading wind energy consultants. This includes eight separate tests by DNV GL, who consider it a Stage 2 remote sensing device, capable of adding value to wind farm developments with project finance requirements.
