Power Grid Corp aims to boost energy supply to northern states

State-owned Power Grid Corp will soon begin commercial operations of 1,500 MW second pole of Champa-Kurukshetra high-voltage direct current line, which is likely to improve power supplies to Northern India, industry sources said.

Punjab, Haryana, Uttar Pradesh, Rajasthan and adjoining areas are expected to benefit from operationalisation of the second pole of the high voltage direct current (HVDC) power transmission link.

It will mainly interconnect the independent power producers in Chhattisgarh as they will be able to supply power to northern states.

“Power Grid has successfully completed trial operations of 1,500 MW, Pole-II of ±800kV HVDC Champa-Kurukshetra transmission system. The pole would soon be put to commercial operations after seeking regulator’s approval,” an independent power producer said.

The first pole of 1,500 MW of the HVDC link has already started commercial operations earlier in March this year. The link’s capacity will be enhanced to 3,000 MW after the second pole begins commercial operation. The link has four poles of 1,500 MW each.

The source further said the 3,000 MW capacity will be available for evacuation of power from energy resource region of Chhattisgarh including Chamoa, Raigarh and Raipur; to Punjab, Haryana, Uttar Pradesh, Rajasthan and adjoining areas.

The first pole of the HVDC Terminal at Champa along with 2,576 km Champa-Kurukshetra HVDC Transmission line was commissioned at a total cost of about Rs 6,300 crore.

This transmission system is further being upgraded to 6,000 MW capacity at an additional cost of Rs 5,200 crore. The entire project of 6,000 MW capacity is expected to be completed by December 2018.

The transmission system has been designed using HVDC Technology and will facilitate in meeting controlled power flow requirement, the flexibility of operation as well as maintaining system parameters within limits through its control mechanism.

The link augments the inter-regional capacity of the Northern region with the Western region, thereby facilitating the economic dispatch of power and exchange of surplus power between the Northern region and Western region, depending on the availability of generation and load demand in each region.
