Hitachi Energy wins contract to connect one of the largest offshore wind farms to the UK’s main power grid

HVDC Light, a high voltage direct current system, will connect the Horncia 3 wind farm, which provides renewable energy to more than three million homes.

Dubai: Hitachi Energy, the world leader in power grid markets and technology, today announced that it has won a major order from Orsted, the world’s leading renewable energy company, for two high-voltage direct current (HVDC) systems to transmit carbon-neutral electrical power. from a power farm. The Hornsea Three winds are located 120 km off the east coast of the United Kingdom.

The wind farm will have the capacity to generate at least 2.85 gigawatts of renewable electricity, enough to power more than three million homes in Britain. With more than 200 wind turbines installed over an area of ​​approximately 700 square kilometers, this farm will be one of the largest offshore wind farms in the world. This project is a critical step in achieving Britain’s energy security strategy, which aims to provide up to 50 gigawatts of electricity from offshore wind by 2030.

Hitachi Energy has provided support to Ørsted by connecting the Horncia 1 and Horncia 2 offshore wind projects to the main onshore grid, while Horncia 3 will be the first project within the Horncia cluster to use the current transmission system. High Voltage Direct HVDC from Hitachi Energy.

The entire HVDC system, including the offshore platform, is delivered in partnership with Aibel. Hitachi Energy will supply two HVDC Light switching systems, while Able will supply two offshore HVDC switching platforms. The platform is based on Hitachi Energy’s modular high-voltage direct current system, together with its advanced MACH monitoring and protection system. As the HVDC offshore wind energy market grows and becomes increasingly complex, Hitachi Energy will continue to develop solutions with its customers and partners to enable a more resilient offshore wind power grid in the future.

Niklas Pearson, Managing Director, Grid Integration, Hitachi Energy, said: “Offshore wind energy is a critical part of the transition to clean energy, while our HVDC technology is essential for the efficient transfer of electricity to the grid. Onshore energy. To keep pace with the rapid growth of the offshore wind energy market, partnerships and collaboration are key factors in delivering services at the speed and scale needed to achieve our goals of decarbonisation and energy security.”

For his part, Patrick Harnett, Vice President of Programs at Ørsted UK, said: “Orsted’s vision is to build a world entirely green energy, and in this context Horncia projects represent an important step towards this goal in the UK to achieve.” : “Together with Hitachi Energy, we are demonstrating that renewable sources of energy such as offshore wind play a key role in the world’s journey towards sustainability. The Hornsea 3 project will not only provide low-cost and clean energy to millions of homes in the UK. , but will also create thousands of jobs, quality work and multi-billion pound investment opportunities within the offshore wind energy supply chain in the UK and abroad.”

Hitachi Energy is providing four HVDC conversion stations to convert alternating current to direct current for transmission through cables on the seabed, and then converting it back to alternating current for integration into the onshore power grid. Two of the substations will be installed on offshore platforms and the other two will connect power to the onshore grid.

Notes to editors

Hitachi Energy’s high-voltage DC system combines high-level expertise in high-voltage DC shunt valves, MACH converters and high-voltage transfer switches, with system studies, design, engineering, procurement and installation supervision. and playback.

HVDC Light is a voltage source switching technology pioneered by Hitachi Energy and is the technology of choice for many power grid applications, including the interconnection of national power grids and the integration of offshore wind energy fields with onshore transportation systems. Distinctive features of HVDC Light technology include uniquely integrated power switching stations, which ensure exceptionally low electrical losses.

Hitachi Energy pioneered commercial HVDC technology nearly 70 years ago and has delivered more than half of HVDC projects worldwide.
