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.
