The contract in South Korea requires Alstom to design and deliver equipment for a 33km energy corridor in Seoul region.
The ±500kV HVDC link, which has 1.5GW of power capacity, will transmit output from the Dangjin power plant in the west of South Korea to the Pyeongtaek area, east of Dangjin.
The HVDC line commutated converter (LCC) scheme was awarded to Alstom’s joint venture KEPCO-Alstom Power Electronics Systems.
In Canada, Alstom has secured a contract to design, deliver and install a point-to-point HVDC solution for the Labrador-Island Transmission Link.
Under the contract with Nalcor Energy, the company will supply a ±350 kV bi-pole system featuring two LCC stations, near Muskrat Falls and Soldiers Pond, near St. John’s.
It will also feature a pair of cable compounds on both shores of the Strait of Belle Isle to link submarine cables crossing the strait to the onshore overhead transmission lines.
The transmission link is part of Nalcor Energy’s Lower Churchill hydroelectric project in Labrador, Canada.
It will run 1,100km from Muskrat Falls near Happy Valley-Goose Bay, Labrador, to Soldiers Pond, Newfoundland.
The link will transmit hydro electricity from the 824MW Muskrat Falls project to the island of Newfoundland.
In India, Alstom won the second phase of the 800kV Champa-Kurukshetra Ultra-High Voltage Direct Current (UHVDC) line contract from Power Grid Corporation of India Limited (PGCIL), after securing a first contract in 2012.
The new 3000MW transmission link will run in parallel with the first UHVDC transmission link, increasing the total transmission capacity to 6000MW.
The second phase of the UHVDC system includes the 1,365 km long energy highway between Champa in central India and Kurukshetra in northern India.
Under the contract, Alstom will construct two ±800 kV, 3000MW converter terminal stations and deliver other related servives.
The contract also requires Alstom to design, manufacture and deliver ±800 kV UHVDC thyristor valves, 32 converter transformers, 400 kV gas-insulated switchgear, substation equipment, and communication and supervisory control and data acquisition systems.
