Siemens and Sumitomo to supply HVDC transmission system to India’s POWERGRID

A consortium between German company Siemens and Japan-based Sumitomo Electric Industries has received a new order to deliver a high-voltage direct current (HVDC) transmission system for operator Power Grid Corporation of India (POWERGRID).

The combined order volume for Siemens and Sumitomo Electric is approximately $520m. As part of the project, the consortium will install a 200km-long Pugalur-Trichur ±320KV HVDC connection to serve as the country’s first direct current (DC) link, equipped with voltage-sourced converter (VSC) technology.

The HVDC system will connect Pugalur in the southern state of Tamil Nadu to Trichur in Kerala State in South-West India.

Under the terms of the deal, Siemens will deliver two converter stations with two parallel converters, each rated 1000MW. Sumitomo Electric will be responsible for a 128km XLPE HVDC cable system in the DC circuit, featuring fur cables for a route of 32km each.

"We are proud to announce that this project will be the first HVDC link in India featuring VSC technology."

Siemens' energy management chief executive officer (CEO) Ralf Christian said: “We are proud to announce that this project will be the first HVDC link in India featuring VSC technology.

“Latest innovations will help achieving ambitious grid programmes, like the "24 x 7 Power for all" initiative of India’s Ministry of Power, to meet the growing power demand.”

Siemens' scope of supply for the project involves design, engineering, delivery, deployment, commissioning, and major equipment supplies of the complete HVDC stations, including transformers, converter valves, cooling systems, as well as control and protection technology.

POWERGRID’s grid connection is expected to begin operations in the first half of 2020.
