Borssele Alpha & Beta

The development of the Borssele Alpha and Beta offshore transformer platforms is viewed as a piece of Dutch ingenuity. These platforms have a combined capacity of 1,400 megawatts of green energy. Iv collaborated with HSM on the design of these platforms, including procurement and integration of the high-voltage (high voltage) components supplied by TenneT TSO B.V. and all balance-of-plant materials. The transformer platform Borssele Alpha is required to connect the wind farms being built offshore in the southwest section of Borssele 1 & 2 in the Dutch North Sea. Together with the Borssele Beta project, the Borssele Alpha project is the first large-scale grid connection built under the National Energy Agreement for offshore wind farms in the Netherlands.

From a technical point of view, TenneT’s high availability and reliability requirements are the main challenge within the project. TenneT requires an availability of 99.964% for the grid connection. This means that the unmanned transformer station may be out of operation for a maximum of 3.15 hours per year. Apart from the financial consequences of unavailability, one of TenneT’s main objectives is to promote wind as a reliable energy source. The station has been fully certified by DNV GL for three components: the topside, the jacket and the foundation.

Generating 1,400 megawatts of green energy will make it possible to supply one and a half million homes with sustainable electricity annually. This project will help reduce CO2 emissions and accelerate the transition to renewable energy sources, bringing the Netherlands closer to its sustainability goals.
