TenneT’s 2GW programme

The IJmuiden Ver 2GW platforms are the first in the world to operate using 525 kV voltage technology. The development is part of TenneT’s 2GW Programme.

For the GE-Seatrium Consortium (GSC), Iv is designing and engineering a series of 2-gigawatt platforms for TenneT in the North Sea: IJmuiden Ver Beta, IJmuiden Ver Gamma, and Nederwiek Beta. Iv is responsible for detailed engineering of the topsides and jackets, as well as joint procurement of equipment and auxiliary systems. The first platform, IJmuiden Ver Beta, serves as a blueprint for the subsequent offshore platforms in the programme.

Designing platforms of this scale and voltage level has never been done before. It presents significant technical and logistical challenges and requires close coordination with all partners and suppliers across multiple time zones.

The combination of size, system complexity, and strict offshore requirements calls for practical, efficient, and buildable solutions. Iv’s design focuses on structural integrity, maintainability, and future-proof operation. The design focuses on achieving the Lowest Levelised Cost of Energy (LCOE) while ensuring long-term reliability and environmental integration through nature-inclusive design principles.

Each platform is approximately the size of a football stadium. With a total capacity of 6 gigawatts, the platforms can supply green energy to around six million homes. This equals approximately 70% of all private households in the Netherlands. The IJmuiden Ver 2GW project represents a major step in the development of large-scale, efficient, and environmentally responsible offshore power transmission
