GE Grid Solutions has reached a new milestone in transmitting electricity in India.

The company’s Champa-Kurukshetra ultra-high-voltage direct current (UHVDC) project in India is now capable of transmitting 4,500MW of electricity.

The direct current link is now transmitting more electricity than any other DC link in India.

This follows the recent successful energisation of the third of four poles planned for the ±800kV UHVDC transmission line.

The ±800 kilovolts (kV) UHVDC transmission line is a crucial component of the Indian government’s electricity-for-all initiative, providing reliable electricity for 46% of its population.

The line transmits to consumers in Punjab, Haryana, Delhi and Uttar Pradesh.

Upon completion, the 1,305-km link will transmit 6,000MW of electricity, making it one of the largest generation-to-consumption transmission systems in the world.

Energy interconnection is a hot topic disrupting the utility industry in India and will be a key focus at POWERGEN INDIA and Indian Utility Week conference. For more details visit https://www.powergen-india.com/ or IUW.com

Phase 1 of the project, completed in 2017, provided 3,000 MW of transmission capacity.

A special feature of the Champa project is the use of an overhead line with a dedicated metallic return, which uses a neutral conductor as a part of the DC circuit.

GE is the first company in the world to demonstrate this technology with this project and is, therefore, providing additional value to the customer by eliminating the typical technical and environmental issues associated with the traditional electrode solution.

With the growing renewable energy market, the nation now boasts an installed capacity of over 360GW, making it the third-largest electricity producer in the world. However, to meet the government’s vision of power-to-all and to ensure last-mile connectivity, continuous development of a robust transmission network is vital for the country.

Power Grid Corporation of India Ltd (POWERGRID), India’s largest state-owned transmission company, is helping address this issue by connecting the power deficit northern Indian region with power surplus regions of eastern India using GE’s UHVDC technology.

“This project also includes an integration where two separately designed bi-poles are running in parallel operation over the same DC transmission line, a design feature only seen on two other HVDC projects in the world, both of which GE was involved with, a great compliment to our legacy and current HVDC controls capability,” said Rajendra Iyer, head of Grid Integrated Solutions at GE’s Grid Solutions.
