PGE Energia Odnawialna S.A. finished the procurement procedure for a two-year measurements campaign of wind conditions in the Baltic Sea using a floating Lidar device. The campaign will be carried out in the region of the planned Baltica offshore wind farm.
Lidar is a state-of-the-art device mounted on a floating three-ton platform (4 x 4 x 4.5m) utilised for wind measurement using a laser beam. With its battery charged independently via photovoltaic panels, a fuel unit and micro wind turbines, it can operate at sea for many months.
Compared to a traditional wind measurement tower, many advantages of Lidar include the capacity to carry out surveys directly at the height of rotor axes of the planned windmills. Apart from a precise measurement of wind velocity and direction, the device will send data concerning the height and length of waves and the direction of sea currents via a satellite.
Surveys in the Baltic Sea will start as early as this year’s autumn and will help obtain full knowledge on possible extent of electricity generation in the Baltica offshore wind farm. Measurements will be carried out approx. 32 km from Łeba.
