Siemens PTD awarded order over 170 million – 688.000 tons of CO2 will be saved

Siemens Power Transmission and Distribution (PTD) and consortium partner Bharat Heavy Electricals Ltd (BHEL) have been awarded an order by the Power Grid Corporation of India Ltd, New Delhi, with a total value of about 235 million euros financed by World Bank to construct a high-voltage direct-current (HVDC) transmission route. Siemens’ share of the total order volume amounts to 170 million euros. The purpose of the new HVDC transmission system is to strengthen the power supply to the growing region around New Delhi. The system is scheduled to go into service in November 2009.

This is the fourth long-distance HVDC transmission link in India. The power transmission system will transport electrical energy with low loss from Ballia in the east of Uttar Pradesh province to Bhiwadi, 780 km (485 miles) away in the province of Rajasthan near New Delhi. In comparison to a conventional 400 kV AC transmission line this HVDC transmission link improves energy efficiency so that 688.000 tons of CO2 will be saved.

As head of the consortium, Siemens has overall responsibility for the project, including the design of the HVDC transmission system, and will deliver the bulk of the core components. The company will also undertake the transport functions, construction work and the installation and start-up. Partner BHEL is supplying transformers for one of the two converter stations as well as switchgear components.
The new long-distance HVDC transmission link is the second system that Siemens is building in India. The first was the “East-South” long-distance link, which still currently ranks as the second longest HVDC transmission link in the world. Since 2003 the Siemens system has been transporting electrical energy with low loss from the Talcher power plant complex in the state of Orissa in the east of India over 1450 km (900 miles) to the industrial region around Bangalore in the south.

The Siemens Power Transmission and Distribution Group (PTD), headquartered in Erlangen, Germany, is one of the leading global players in its market sector. As a product supplier, system integrator, solution designer and service provider, Siemens PTD ensures - for utilities and industry alike - the efficient and reliable transmission of electrical energy from the power plant to the consumer. With a worldwide workforce of about 27,500 and operations in more than 100 countries, PTD had sales of 6.5 billion euros in fiscal 2006.
