jesper2024 The Soo Green HVDC Link is a proposed 2,100 MW underground transmission line designed to connect wind-rich Iowa with major demand centers in Illinois. Unlike most HVDC projects, Soo Green will be buried along existing rail corridors, reducing land-use conflicts and speeding permitting. If completed, it would be one of the first U.S. projects to … Read more
The SunZia HVDC Project is a landmark 3,000 MW transmission system connecting renewable energy resources in New Mexico and Arizona to demand centers in Arizona and California. It is one of the largest HVDC projects currently under construction in the United States and a cornerstone for integrating Southwestern wind and solar power into the western … Read more
The NordLink HVDC project is a 1,400 MW submarine interconnector linking Norway and Germany. It became operational in 2021 and is one of Europe’s most important cross-border transmission projects, often referred to as the “green cable.” The interconnector enables the exchange of Norwegian hydropower with German wind and solar, strengthening energy security, supporting decarbonization, and … Read more
The North Sea Link (NSL) is the world’s longest subsea HVDC interconnector, connecting Norway and the United Kingdom. With a capacity of 1,400 MW and spanning 720 km, it allows hydropower from Norway to complement wind generation in the UK, and vice versa. Operational since 2021, the project is a cornerstone of Europe’s strategy to … Read more
The Ultranet HVDC project is a 2,000 MW onshore transmission line in Germany, designed to carry renewable energy from the country’s wind-rich north to its industrial south. As part of Germany’s Energiewende (energy transition), Ultranet is a critical infrastructure upgrade aimed at balancing regional supply and demand while reducing reliance on fossil fuels. Unlike subsea … Read more
The IFA2 HVDC interconnector is a 1,000 MW subsea transmission link connecting the electricity grids of the United Kingdom and France. Commissioned in 2021, it is one of several strategic interconnectors operated by National Grid to enhance cross-border power flows. The project strengthens energy security, balances renewable variability, and allows surplus renewable generation to flow … Read more
The Pugalur HVDC project is a 2,000 MW transmission link in India, connecting Pugalur in Tamil Nadu with Trichur in Kerala. Commissioned in 2021, it is India’s first Voltage Source Converter (VSC)-based HVDC project and plays a key role in strengthening the southern regional grid. The project helps balance renewable generation, improves grid reliability, and … Read more
The Itaipu HVDC project is one of the largest and most iconic HVDC transmission systems in the world. Commissioned in the 1980s, it transmits power from the Itaipu Hydroelectric Dam on the Brazil–Paraguay border into the Brazilian grid. With a combined capacity of 6,300 MW, Itaipu remains a benchmark for large-scale HVDC infrastructure, showcasing how … Read more
The ADNOC HVDC Project is the first large-scale subsea HVDC transmission system in the Middle East. With a planned capacity of 3,200 MW, it will connect offshore oil and gas production facilities in Abu Dhabi to the onshore grid. By replacing offshore gas turbines with electricity supplied via HVDC, the project will significantly reduce carbon … Read more
Submarine HVDC cables rank among the most capital-intensive assets in global energy infrastructure, with installation costs running €2–5 million per kilometer plus hundreds of millions for converter stations. These undersea links are critical for offshore wind integration and cross-border interconnectors, but their price tags often exceed €2–3 billion per project. For investors, the growth … Read more
