Power Grid Corporation of India has chosen Siemens to modernize the country’s first and oldest high voltage direct current (HVDC) link, Vindhyachal. Located in Madhya Pradesh, the 500-megawatt HVDC back-to-back system was put into operation in 1989 to interconnect the asynchronous 400-kilovolt alternating current networks of the Northern and Western regions. By installing its latest HVDC components Siemens will extend the useful life of the system.
This will be the first Siemens HVDC modernization project in India. The key components for the upgrade will be delivered from the Indian facility in Goa.
Siemens is a technology powerhouse that has stood for engineering excellence, innovation, quality and reliability. The company focuses on the areas of electrification, automation and digitalization.
