MAINGRID — The MAINGRID team has successfully completed a project to install two 115 m meteorological masts in Osakarovka

In early January 2026, our team, together with Deutsche WindGuard GmbH, an international company specializing in wind resource assessment and support for renewable energy projects, successfully launched a wind measurement campaign on two meteorological masts in the Karaganda region.

As part of the project, modern measuring equipment was installed on the masts, including heated Thies Clima sensors that ensure stable operation in winter conditions, as well as a Campbell Scientific CR1000X data logger for reliable data collection and storage.

A separate autonomous power supply system was implemented for the sensors, providing 230 V through an inverter. This ensures continuous measurements and high quality of the collected data.

The launch of the campaign is an important stage in assessing the region’s wind potential and further developing wind energy projects.

How a wind measurement mast works

Anemometer cups: turn with the wind speed at their own heightVanes at 112 and 78 m and the compass mark: where the wind blows fromLogger at the foot: one sample a second, a 10-minute averageA 115 m mast with sensors from 10 to 115 m. Wind speed grows with height by a power law (α = 1/7), so the upper cups turn faster than the lower ones. The logger reads every sensor once a second and stores 10-minute averages; 12–18 months of them become the Bankable Report. The reading at the bottom right is at 100 m: speed, direction and the average of the current 10-minute interval. The model runs 20× faster than real time, with 12 % turbulence.
