The Alrosa diamonds producer in Yakutia, Siberia, is interested in purchasing two hydroelectric power plants on the Vilyui river from the Yakutskenergo power utility, which is controlled by Unified Energy Systems (UES).

According to the Interfax news agency Alrosa is reported to have approached UES with a view to acquiring the plants, but a large number of issues are unresolved, such as the future development of the electricity sector in Yakutia and cross subsidisation of prices.

The Vilyui 1 and 2 hydro plants on the Vilyui river have a combined generating capacity of 680MW and generated 2.8BkWh of electricity in 2005.
