18 HIGHLIGHTS Engineering, the ESKOM service subsidiary, the general contractor for these works. VA TECH HYDRO has already dispatched the first set of windings (31 tons) by air freight, an expensive but necessary mode of transport, due to the urgency of the requirement. Work on site began in August 2003 and was completed by early October 2003. Unit 2 went into full commercial operation on October 14, 2003. The second set of stator windings was dispatched by sea freight in December 2003, and installation began in early March 2004. Given the strongly growing power demand in South Africa, the rehabilitation of Vanderkloof power station will help to ensure maximum availability of power by improving reliability and efficiency while reducing partial discharge effects and extending service life. Technical data: Output: 133.3 MVA Voltage: 11 kV Speed: 125 rpm Stator diameter: 9,720 mm Walter Schwarz Phone +43/1 89100 3557 walter.schwarz@vatech-hydro.at TURKEY YUKARI MERCAN & SÜLEYMANLI On November 6, 2003 VA TECH HYDRO in France signed another "Water to Wire” contract in Turkey. Yukari Mercan HEPP is located near Erzincan, close to previous Girlevick Mercan HEPP. IÇTA, the client, confirmed his satisfaction with the completion of a previous project by awarding his next contract also to VA TECH HYDRO. The scope of supply includes two horizontal Pelton units, with speed governors, spherical inlet valves, synchronous generators, C&P systems and all electrical equipments. Interesting financing facilities have been proposed by VA TECH Finance. Meanwhile, Süleymanli, also a "Water to Wire” HEPP, signed with ISKUR in December 2002 (two compact Francis units with associated equipment) is already at the final stage of site installation, fully within schedule, also to the client’s satisfaction. These successes will help VA TECH HYDRO to strengthen its leading position in the Compact hydro market in Turkey.

The existing plant, erected in 1924 and equipped with a horizontal Francis turbine, no longer met today’s power generation standards. The buildings had to be reconstructed, refurbished and expanded to accommodate the new machine. The existing and now defunct generator turbine unit will remain in the powerhouse as a showpiece. The new TC1703 turbine governor was installed for plant control. The entire hydraulic steel structures were also integrated into the control system. The power plant was commissioned in October 2003 with the trial run to follow. Final inspection took place in December 2003. Technical data: Output: 1.8 MW Head: 6.39 m Speed: 272.7 rpm Runner diameter: 1,600 mm Michael Schilling Phone +49/751 83 3192 michael.schilling@vatew.de LIECHTENSTEIN LETZANA Liechtensteinische Kraftwerke (LKW) awarded VA TECH HYDRO a contract to supply, install, and commission the entire electromechanical equipment for the Letzana power plant refurbishment project. The existing turbine had been installed at a manufacturing plant, which was subsequently reconstructed to serve other purposes. The newly erected powerhouse in the immediate vicinity of residential homes and service enterprises had to meet the most stringent requirements in terms of sound emissions. VA TECH HYDRO’s scope of deliveries included a horizontal 2-jet Pelton turbine and a 470 kVA synchronous generator. The “Water to Wire” (W2W) plant is equipped with a TM1703 turbine governor. Connection to the MIC1703 in the reservoir has been effected by modulating the signal upon the power supply line of the intake building. The plant data are fed into the SAT250 network control system supplied by SAT.
The new unit is remotely controlled by an AK1703 power controller. The plant was handed over to the customer for commercial service in mid- September 2003. Technical data: Output: 400 kW Head: 180 m Speed: 1,000 rpm Runner diameter: 550 mm Roland Hugentobler Phone +41/71 950 01 66 roland.hugentobler@vatech-hydro.ch FRANCE MIEGEBAT First MicroGuss TM Pelton runner for Société Hydroélectrique du Midi (SHEM). The French customer SHEM based in Paris and Toulouse (part of SNCF railways) ordered from VA TECH HYDRO Switzerland a Pelton Micro- Guss TM runner for Miègebat power plant situated in the occidental Pyrenees. This new MicroGuss TM Pelton runner replaces a cast iron runner, which has been in service for over 30 years. We could convince the customer that a Micro-Guss TM runner would be the best solution for his long term investment. This is the first MicroGuss TM Pelton runner to be delivered to this important French customer (number 3 after EDF and CNR) who has about 50 Pelton runners in operation. The runner should commence industrial operation in August 2004, after completion of the efficiency verification tests.

On October 10, 2003 we received a letter of intent from the Société des Forces Motrices de Chancy Pougny for the rehabilitation of turbine generator units 1 and 2 of Chancy Pougny power plant. This rehabilitation consists of replacing one or two Francis units of a total of five having been in service since 1925 with two new Kaplan units. The contract for the rehabilitation of two units was confirmed at the beginning of 2004. It will be realized in a consortium with ALSTOM and VA TECH HYDRO as project leader. Technical data: Output: 12 MW Head: 11.4 m Speed: 88.24 rpm Runner diameter: 4,800 mm Pedro Lopez Phone +41/21 925 7713 pedro.lopez@vatech-hydro.ch SPAIN PORTODEMOUROS Work was successfully completed at Portodemouros plant in December 2003 with the plant being handed over to Unión Fenosa after commissioning of the equipment. In May 2002, VA TECH HYDRO in Spain was awarded a contract by Soluziona Ingeniería, S.A., the engineering company of the Union Fenosa group, for the supply, instal- HIGHLIGHTS lation and commissioning of the electromechanical equipment for the Portodemouros plant (ecological flow), located in Pontevedra province, Galicia region, in northwest Spain. Union Fenosa is the third main utility in Spain. VA TECH HYDRO’s scope of supply included 1 penstock ND 1800 and 20 m long, a dewatering pipe ND 2400 and 35 m long, 1 vertical 11 MW Francis turbine, 1 water-cooled generator, 1 butterfly valve ND 1700 NP12, 1 gate valve ND 1600 and governor system. This existing power station, owned by Union Fenosa, is located inside a cavern excavated in the mountain beside the dam. The existing units are vertical Francis, with an output of 39 MW each. The connection to one of the existing penstocks was made with a special bifurcation piece. All equipment supplied by VA TECH HYDRO (turbine, valves, generator, penstock, etc.) is located below the ground level of the power station, in several tunnels and pits excavated in the soil. For this reason and because of the small dimensions of the excavated area, all transport, handling and erection work was extremely complicated and required very careful coordination with civil work. Soluziona signed the provisional acceptance and confirmed their satisfaction with the timely completion of the project. We expect to work together with this company in several new projects to be started in 2004.
