TenneT and RWE have signed agreements for planning and electricity delivery from OranjeWind, an offshore Dutch wind farm. RWE is building the 800 MW capacity farm and will make use of TenneT’s help to deliver renewable power from 2027.

TenneT and RWE have signed a connection & transmission agreement (CTA) and realization agreement (REA) covering the realization of the offshore grid connection of OranjeWind and the transmission of the electricity produced by RWE’s wind farm on TenneT’s platform. The agreements not only specify planning but also how the electricity will be delivered from the wind farm to ensure stability in the grid. The connection will link to the high-voltage substation in Wijk aan Zee and will be operational by 2026. The timeline for the offshore wind farm is ambitious and TenneT will prove instrumental in completing the project and delivering renewable power from 2027.

OranjeWind will have an installed capacity of almost 800 MW and will use a combination of smart innovations and investments to achieve a perfect balance of supply and demand. It will be built 53 kilometers off the Dutch coast. These innovations include floating solar panels, a subsea lithium-ion battery, and a LiDAR system to predict power production more accurately. In addition, RWE will invest in onshore system integration, such as electrolysis capacity and e-boilers, to match power generation and offtake.

Mr. Sven Utermöhlen, CEO of RWE Offshore Wind, stated, “I am pleased that we were able to sign the contracts so quickly, as these agreements guarantee the transport of the electricity generated by the OranjeWind wind farm. This is an important milestone in the project that brings us one step closer to realizing our perfect match for system integration and supplying sustainable electricity to over one million households in the Netherlands. For this, good cooperation with TenneT is essential.”

Mr. Marco Kuijpers, Director of Offshore Projects of TenneT, said, “The connection of this wind farm marks another important step in the goals towards a sustainable energy system. Through the innovations in this project with offshore solar panels and batteries, we can jointly gain experience in building the energy system of the future. We look forward to a good cooperation with RWE and we are happy that together we can make a major contribution to the Dutch energy transition.”

RWE’s largest projects include the 1,400 MW Sofia offshore wind farm currently under construction off the UK coast and the recently commissioned 342 MW Kaskasi offshore wind farm off the German island of Heligoland. The company is also exploring new offshore markets, such as America and Japan, and developing solutions for smartly charging electric vehicles.

TenneT is realising seven standard offshore alternating current (AC) connections in the Netherlands, each with an average capacity of 700 MW. From 2029, wind farms further offshore will be fitted with 2 GW of standard direct current (DC) connections.
