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. At stage 3 a device is considered proven for use in the assessment of wind farm sites. The data may be used quantitatively within formal wind speed and energy assessments with only limited or no site-specific validations against conventional anemometry.
