SSE has installed a Zephir 300 lidar at the 108MW Bhlaraidh wind farm in Scotland, as part of a plan to replace met masts at the developer’s projects.

The Zephir unit delivers wind measurements from ground level to 200 metres, and has been integrated with the onsite Vestas SCADA system.

The lidars will be used to optimise the management of the site, including the delivery of turbine power curve measurements, SSE said. 

SSE project delivery engineering manager Alan Evans said: “We have successfully completed part of an ongoing project to innovate around the cost of energy of our wind farms, which has resulted in Zephir lidar being selected to support SSE in the replacement of our permanent met masts.

“These lidar systems provide a wider more appropriate set of wind measurements to enable more active operation and optimisation of our wind farms, all without most of the infrastructure and investment required for tall met masts.”

Zephir head of commercial marketing and product development Alex Woodward said: “In a changing world of wind farm economics, site owners and operators are seeing the value that can be delivered by operational anemometry and with lidar that can be achieved at a lower through life cost than traditional met masts, with the same level of grid compliance and SCADA-integration.”
