Galetech Measurement Services has long played a central role in Ireland’s renewable energy landscape, supporting developers with wind resource campaigns across the full lifecycle of wind development, from greenfield measurement campaigns through to operational performance verification and grid-compliance monitoring. In each case, the requirement is the same: accurate, accepted data delivered reliably in real-world conditions.
They have built their reputation the hard way: by delivering trusted wind measurements, repeatedly, in real Irish conditions – and doing it over long time horizons where “bankable” must mean sustained, supported, and repeatable. Their fourteen-year relationship with ZX Lidars traces the industry's own evolution from early ‘ZephIR-era’ instruments to the fresh new ZX generation, and now to ZX 300e, where independent IEC classification outcomes and grid-operator acceptance are directly reshaping how wind farms are measured and monitored.

ZX Measurement Services delivered an integrated wind measurement campaign at Crystal Rig Wind Farm for Fred. Olsen Renewables Ltd, combining early-stage ZX 300 wind Lidar deployment with the installation and commissioning of a fully instrumented 100 m meteorological (met) mast.

This phased approach enabled early wind data collection while establishing a long-term reference measurement system, accelerating project timelines and improving early-stage decision-making.

ZX 300e is a newly-developed wind lidar profiler, with improved performance compared to ZX 300, which has itself been used for many years in many resource assessment campaigns across the world.

Under highly controlled in-house conditions, the wind direction accuracy of a ZX 300e lidar was determined to be +/- 0.5 degrees.

This work presents validation for continuous wave lidar TI transfer function METICE, developed by ZX Lidars to address systematic differences between lidar-derived turbulence intensity and traditional cup anemometer measurements. Sound performance is demonstrated under unstable, neutral, and stable atmospheric conditions, and for a range of operational turbine heights showing that the transfer function successfully compensates for strong height-and stability-dependent differences.
