Hydro back on the rise

Russia’s giant power sector has a total electricity generation capacity of more than 200 GW and in 2001 generated approximately 846.5 billion KWh of energy. After the collapse of the Soviet Union, electricity generation declined dramatically between 1992 and 1999, but since then has gradually recovered. The power industry of the biggest country on earth includes 440 thermal and hydropower plants and 30 nuclear power plants.

Hydro power plays an important role The largest hydroelectric stations in The Russian government has stated in the country’s electricity supply. Russia are the Sayano-Shushenskaya that it intends to expand the role of According to recent statistics of the station (6,400 MW), the Krasnoyarsk nuclear and hydro power in the government-owned Unified Energy station (6,000 MW), and the Bratsk future.

Bulgarian hydro potential supporting energy export

Bulgaria’s energy sector is dominated by nuclear power and imported fossil fuels. The energy balance for the country shows that more than 70% of energy consumption is based upon imported fuels. Hydro power accounts for only 6-7% of all electricity generation.

Modernization of all Rila cascade stations

After almost eighty years of successful operation, Granitoid, the owner of the oldest hydropower cascade in Bulgaria, has entrusted Voith Siemens Hydro with a major modernization of the project. In February, a frame contract for modernization comprising new mechanical equipment, elec- trical balance of plant systems as well as a state-of-the-art automation system, was signed by Granitoid and Voith Siemens Hydro.

For the future of Afghanistan: Rehabilitation of Sarobi and Mahipar

Voith Siemens Hydro has been awarded the rehabilitation contract for the Sarobi and Mahipar hydropower plants, not far from the Afghan capital Kabul. The contract, which is worth 16.6 million EUR, was concluded with the Ministry of Water and Power in December 2003. The project will be financed by a loan from Germany’s KfW (Kreditanstalt für Wiederaufbau, Credite Institute for Reconstruction).

51st Ohm Technical Prize awarded to Voith Fuji Hydro in Japan

In November 2003, Voith Siemens Hydro’s Japanese entity, Voith Fuji Hydro K.K. and major Japanese electric utility Tohoku Electric Power Co. Inc., were awarded the prestigious Electrical Science Technologies Enhancement Prize (Ohm Technical Prize). The Japanese Electrical Science Technologies Enhancement Association sponsors this award. Both parties were honored for their significant technical contribution to the hydro power industry through the development of innovative large capacity vertical bulb turbines and generator technologies.

As most of the Japanese locations suitable for large-capacity hydro- power stations with high economic efficiency have already been devel- oped, Voith Fuji Hydro and Tohoku Electric Power Co. have been studying possibilities of modernizing existing power stations and installing new power stations at existing dams for economic and environmental advancement. hypow_7_02-31_RZ.qxd 17.03.2004 14:43 Uhr Seite 17

Venice of the North

In 1991, the citizens voted in a refer- endum to revert to the original name of St. Petersburg.

In spite of its restless history, St. Petersburg has maintained its classical appearance. The panorama of buildings along the banks of the Neva is breathtaking, and the count- less small watercourses create a romantic atmosphere that is certainly comparable to that of Venice.
