ZephIR 300 wind lidar is accepted for use in bankable / finance-grade wind speed and energy assessments with either no or limited on-site met mast comparisons under “benign” conditions.
DNV GL considers ZephIR 300 to be at Stage 3 under “benign” conditions – accepted for use in bankable / finance-grade wind speed and energy assessments with either no or limited on-site met mast comparisons. In October 2012 ZephIR was the first commercial wind lidar system to achieve accreditation at this level.
ZephIR 300 measures wind characteristics onshore and on fixed or floating platforms offshore from just 10 metres (33 feet) up to 200 metres (656 feet) above the installed position to inform wind regime and quality studies during the development and operation of wind farms onshore and offshore. ZephIR 300 is accurate, reliable and affordable, adding value to wind energy projects at every stage – from pre-planning, through development and on to operation. Every system is uniquely subjected to an industry-approved validation process, part of which occurs at the UK’s Lidar and Sodar test site, ensuring repeatable finance-grade data.
ZephIR DM is a Dual Mode variation of the successful 300 system. Mounted inside the spinner or on top of the nacelle, ZephIR DM measures wind characteristics in front of or behind a turbine from just 10 metres (33 feet) out to 300 metres (984 feet), during the operation of wind farms onshore and offshore. ZephIR DM provides valuable advanced wind data for the optimised performance and alignment of wind turbines, for in-situ power performance measurements, to reduce wind loading on turbine components and for specific troubleshooting applications.
