Unified Energy Systems (UES) says it plans to invest US$256M in the construction of the Bureisky hydroelectric power plant in Russia's Far East in 2004, according to the Interfax news agency.

The first and second generating units of 185MW capacity each will be commissioned at the plant this year, with a third unit of the same capacity to be commissioned next year.

UES has submitted a request to the Federal Energy Commission for the fixing of a tariff for electricity produced at the Bureisky plant of US$0.013-0.020 per kWh over the next six months.

The plant, when completed in 2007, will have a total installed capacity of 2000MW, generating an annual average of 7.1B kWh of electricity.
