Russian Transmission Investment Progress Report

The North-West Transmission Grids, branch of OAO "UES FGC", brought on line a new 330-kV Novgorodskaya substation in the city of Veliky Novgorod, as reported in a progress report on the investment program by the RAO UES companies for May 2007. This is the first new 330-kV facility built in the North-West of Russia over the past twenty years. The substation was built in less than two years and has the aggregate capacity of 450 MVA. At the project design stage, the engineers took into account the electricity load growth forecasts for the substation until 2030. The new substation site has distribution switchgear of 330, 110, 35 and 10 kV. Also, the substation has advanced equipment produced by Russian and foreign manufacturers. The investments in the project totaled in excess of RUB1.5 billion.

Now that the new substation is on line it will help improve the reliability and quality of electricity supply to customers in the city of Veliky Novgorod and the surrounding Novgorod Region, and reduce the number of accidents and cut transmission losses.

The Center Transmission Grids, branch of OAO "UES FGC", launched a project to revamp the 220-kV transmission lines "Kurkino - Radishchevo" and "Kurkino - Shmelevo" in the Moscow Region. These steps will help address the capacity shortage in the 220-kV network of the Moscow Energy System and improve the reliability of electricity supply to consumers in the Northern and North-Western Administrative Districts (Okrugs) of Moscow, as well as the Krasnogorsk District and Istra District of the Moscow Region. The power lines are due to come on line in late 2007.

The work currently underway is the final phase of the modernization project at the Zlatoust substation, the first substation of the
500-kV network to be modernized in the Urals area. To date, three transformers with an aggregate capacity of 750 MVA have been installed at the power plant. The project cost is about RUB1,600 million. By end-2007, OAO "UES FGC" will spend RUB681.8 million in funds on the overhaul and modernization projects in the 500-kV network of the Urals Transmission Grids branch, a 2.3-fold increase over 2006.

OAO "Chelyabenergo" put into operation a new 400-KVA transformer substation and a 10-kV transmission line in the Chebarkul District of the Chelyabinsk Region.

OAO "Moscow United Electricity Distribution Company" is continuing the modernization project at the 110-kV Babushkin substation which supplies power to the North-Western Administrative District of Moscow. This substation will be switched to a new voltage class, 220 kV. The project will cost about RUB2 billion and is expected to be completed in 2008.
Also, in May 2007, the RAO UES distribution grid companies started modernization at ten 110-kV substations and brought on line about 100 km of 110-kV overhead and cable lines.<0}
