A 15-megawatt photovoltaic power station, with investment from China-based Sirius Holding Group, has been put into operation in Astrakhan, Russia.

The station generates 15,000 kilowatt-hours of electricity per hour.

Cui Zhiwei, deputy general manager of Sirius, said the company's investment was expected to be recouped in five years.

Power demand in Russia has seen sustainable growth thanks to its economic recovery in recent years.
