Powering Through the Cold:How We Engineered the Impossibe at −43.5°C

−43.5°C.

That's what our turbines had to survive.

The Arkalyk Wind Farm in Kostanay Oblast, Kazakhstan sits at 50°N latitude — one of the coldest operational environments on Earth. Five months of annual snowfall. An average yearly temperature of just 5.8°C. A historical extreme low that breaks most conventional engineering assumptions.

When PowerChina Chengdu Engineering Corporation awarded us the turbine supply contract for this 50 MW project, CRRC Zhuzhou Institute committed to purpose-engineering a solution — not adapting an existing one.

Our answer: 8 units of the WT6250D185H107, with every critical system — gearbox, generator, control, and lubrication — cold-tested in the laboratory against the site's recorded extreme before a single component left our facility.

On December 22, 2025, all 8 turbines achieved full-capacity grid connection. The Arkalyk project now sits on the China–Kazakhstan Capacity and Investment Cooperation Priority Projects List.

25-year design lifespan. In one of the most demanding energy frontiers on Earth: the lights are on.
