Configuration Options

The NRG Mounting Boom | Antenna, S1/WindSensor mounts NRG S1 and WindSensor P2546-OPR Anemometers on NRG 50m and 60m XHD TallTowers. Anemometer cups are positioned at exactly 50.4m and 60.2m heights, respectively. This mounting arrangement complies with guidelines provided in Annex G of both editions of the IEC 61400-12-1 standard.

This mounting solution is well suited for traditional wind resource assessment campaigns as well as Edition 2 power performance tests at operating wind farms in conjunction with a remote sensing device.

NRG tubular tilt-up towers allow companies to perform both internal and contractual power performance testing in a way that does not require the installation of a permanent met tower. No permanent foundations or long-term permitting is needed. These towers reduce the overall cost of the test, allow for short lead times (typically less than a week), and come in an efficient and portable single package, offering more logistical flexibility for wind farm developers and operators working in remote locations.
