Siemens Energy has been selected to connect New York’s first utility-scale offshore wind project to the grid. The 924 MW Sunrise Wind project will be connected to the grid utilising a high-voltage direct current (HVDC) transmission system. According to company statements, this is the first offshore wind project in the US to use HVDC technology. The company has tied up with Aker Solutions to supply the transmission system.

Sunrise Wind is located 30 mile offshore Long Island and is a joint venture between Orsted and Eversource. The offshore wind farm will provide enough renewable energy to power roughly 600,000 homes once it is completed. The HVDC system will consist of two converter stations. The offshore converter station will collect the 66 kV AC power generated by the wind turbines and transform it to 320 kV DC for transmission. Meanwhile, the onshore station will convert the power back to AC to feed it into the distribution grid. 

In September 2021, Toray Industries, Inc. and Siemens Energy partnered for the production of green hydrogen from Polymer Electrolyte Membrane (PEM) water electrolysers using renewable energy sources. In the partnership the membrane technology will be provided by Toray Industries. The partnership would work towards promoting the installation and demonstration of these membranes in Siemens Energy’s large industrial scale PEM water electrolyser. The resulting green hydrogen will not only cater to large-scale power generation, but also sector coupling such as heat, transport, and industrial applications.

REGlobal’s Views: The state of New York has set a goal to achieve 100 per cent of its power requirement through clean energy by 2040. Such offshore wind projects will help bring the state closer to its goal.
