Nearly a third of India’s population are estimated to have no access to reliable power. Numerous cities reel under scheduled ‘load shedding’ (rolling blackouts) by the local power distribution agencies, bringing to a halt industrial operations and impacting livelihood of millions. Thousands of rural areas fare worse, seeing limited or no development due to the lack of electricity.
Technology from Siemens is transforming this situation. High-voltage direct current (HVDC) systems are transmitting power efficiently, safely and reliably over long distances - from the source of power generation to the consumers of power. Due to its superior technology, HVDC transmission has typically 30-50% less transmission loss than comparable alternating current overhead lines.
Siemens has supplied a HVDC power transmission system that connects an ultra mega power plant in Mundra on India’s western coast to the industrial region of Mohindergarh in Haryana, a northern state in India. The total length of the HVDC system is 960 kilometers and is rated for providing continuous power of 2,500 megawatts.
The Mundra-Mohindergarh HVDC transmission line is the first HVDC project in the private sector in India. This transmission line is in addition to two other HVDC transmission lines – the 1,400-kilometer Talcher-Kolar section, one of the world’s largest transmission projects, and the 780-kilometer Ballia-Bhiwadi transmission line. Siemens has installed all the three HVDC systems.
