Power to expand a remote cold mine

Client: GV Gold

Location: Irkutsk region, Russia

Sectors: Mining

The Challenge

Alternative power for a gold mine during the bitter Siberian winter

GV Gold, a gold mining operation in the Irkutsk region of Russia was looking to expand by opening a third mine. But getting power to a remote location in Siberia is no walk in the tundra. True, they could get some power from a nearby hydroelectric plant, but during the winter months the dam overflow was increased to prevent the damn from freezing, which meant a lot less hydro-capacity downstream.


Winter temperature -40 °C
Summer temperature 30 °C
Total power supplied 12MW

The Solution

12 MV ready-to-go power package

We initially installed a 5 MW ready-to-go power station for our client’s immediate needs. Then as winter approached and temperatures dropped to -40°C, we added an extra 7 MW. The total 12 MW of power was used during winter to cover the shortfall in hydro-power and in summer as backup and emergency supply.

The ability to scale a package up or down according to seasonal demands is an attractive option for operators in remote locations. It allows them to finesse their fuel consumption all year round and save on fuel costs by accurately meeting supply with demand.

“The quality of the Aggreko equipment along with the excellent service and technical support has proved that Aggreko was the right choice for GV Gold.”

The Impact

24/7 power with the capacity to scale

Because our equipment is designed for harsh and unfriendly conditions, it provided uninterrupted 24/7 power to the gold mine. It stood up to the freezing temperatures of a Siberian winter and the +30°C harshness of a Siberian summer.

Our work allowed GV Gold to decrease their reliance on patchy local hydropower and control their fuel consumption as and when needed. Our system was flexible enough that – if GV Gold went through another expansion – they could quickly and easily add to the 12 MW extra units they already had.
