Engineering firm Energy3 has announced plans to restart monitoring at four wind farms in Australia and New Zealand, using the ZX 300, a lidar-powered remote sensing device, to resume operations in spite of Covid-19 lockdown measures in place across the countries.

Lidar, which stands for light detection and ranging and relies on a laser to measure ranges and distances remotely, is a more efficient way of measuring a wind farm’s performance than traditional measurement towers, according to Renewable Energy Systems. By eliminating the need to construct a separate tower to house measurement equipment, the use of lidar can improve operational efficiency in general. and the technology could be particularly important amidst the Covid-19 pandemic, with lockdown measures preventing workers from accessing measurement devices or wind turbines themselves to take measurements.

“Lidars present the only solution for wind monitoring campaigns for deployment over this time – met mast work simply cannot not be undertaken in these situations,” said Thomas Cameron, founding partner at Energy3. “Lidars are quick to install, without the need for intensive labour or heavy equipment components.”
