DONG Energy Wins Tender for Dutch Offshore Wind Farms
The Netherlands’ Minister of Economic Affairs has awarded DONG Energy the concession to build The Netherlands’ offshore wind farms Borssele 1 and 2. DONG Energy won the concessions with an average bid strike price, excluding transmission costs of EUR 72.70 per MWh during the first fifteen years of the contract. After that, the wind farms will receive the market price.
Only four years ago, DONG Energy set an ambitious 2020 cost target of reaching EUR 100 per MWh over the life-time of a wind farm, the so-called levelised cost of electricity, including transmission costs. This target, which was later adopted by the offshore wind industry, has now been reached. DONG Energy will, in accordance with the Dutch tender regulation, build Borssele 1 and 2 within four years from today with a flexibility of one year. The wind farms’ capacity of two times 350MW will translate into supply of CO2-free electricity covering the annual power consumption of approximately one million Dutch households.
Country Manager for DONG Energy Netherlands, Jasper Vis, says: “The Dutch government has introduced an ambitious, long-term development plan for offshore wind. The Borssele concessions mark a milestone in the Netherlands’ shift towards green energy, and we look forward to bringing our more than 20 years’ experience with offshore wind into these projects.”
Innovation and scale reduce the cost of electricity
The reduction of cost of electricity is driven by cross-industry collaboration, ongoing innovation of wind turbines and blades, continuous improvements of foundation design and installation methods, higher cable capacity, a growing and competitive supply chain and not least the synergies from building large-scale capacity sites such as Borssele 1 and 2. In addition, the Dutch sites offer good seabed conditions as well as good and stable wind speeds, which contribute to high output from each turbine.
