ONE-Dyas, together with its partners EBN and Tenaz Energy has reached a milestone in the energy transition: the cable connection between the N05-A platform and the German offshore wind farm Riffgat is complete and is being used to produce natural gas. This makes N05-A the first natural gas production platform in the Dutch and German North Sea to run on offshore wind energy. 

Unique: Drilling Also Fully Electric 

For several months now, the N05-A platform has been producing natural gas from a single Dutch well, but drilling of a second well will start soon. The mobile drilling platform that will be temporarily connected to N05-A to drill the well has been converted to run on electric power which is also unique in this part of the North Sea.  This means that both gas production and drilling activities take place with minimal CO₂ emissions: a breakthrough in offshore gas projects.

Environmental Benefits and Security of Supply 

The platform electrification reduces greenhouse gas emissions to virtually zero. This natural gas production supports the climate targets, which are aimed at reducing emissions. At the same time, it makes an important contribution to the security of natural gas supply during the energy transition. The N05-A platform can produce two billion cubic metres (2 bcm) of natural gas per year, equivalent to 7% of Dutch demand and more than 2.5% of German demand. The Dutch-German energy project is strategically located in the border area in the North Sea, where several small fields together contribute to a stable energy supply for the Netherlands and Germany. The potential of these fields in this so-called GEMS area is approximately 50 bcm of natural gas. Gas demand in 2024 was approximately 75 bcm in Germany and approximately 30 bcm in the Netherlands. 

Chris de Ruyter van Steveninck, CEO ONE-Dyas: 
"As long as there is demand for natural gas, we will take our responsibility together with the Dutch and German governments. The electrification of N05-A increases the sustainability of North Sea natural gas and helps to reduce our reliance on imported natural gas from countries on which we do not wish to be fully dependent. It is a powerful signal that the Netherlands and Germany are fully committed to local gas production in the North Sea. The volumes from N05-A and surrounding fields adjacent fields are contributing significantly to enhancing our selfsufficiency.”  

Bilateral agreement for a stable energy supply 

The development of the gas fields in this area is fully aligned with Dutch and German government policy, which, during the energy transition, is committed to stimulating natural gas extraction in the North Sea and minimizing import dependency. On 28 August 2025, the neighbouring countries of Germany and the Netherlands signed a bilateral agreement to this end, in order to guarantee gas supply security for residents and businesses and to contribute to a stronger European gas market.
