The company said that it currently remains on track for the start of gold production later this month.
The power unit at the site consists of four diesel generators with a combined capacity of 4MW.
The company has launched the power unit, with the gold plant and other facilities being switched to the permanent power supply.
According to the company, final testing of the mills is nearly complete and other mechanical equipment has been checked.
Hydraulic tests of the plant equipment and piping are expected to be finished soon, and after that, tests of the plant equipment with waste rock and low grade ore will be undertaken.
Trans-Siberian Gold said the works at the underground mine continue as planned.
