DONG Energy awarded contract to build the world’s biggest offshore wind farm

By Michelle Froese | September 12, 2017

DONG Energy has been awarded a contract to build its Hornsea Project Two offshore wind farm, at the lowest-ever price for offshore wind in the UK. With a massive capacity of 1,386 MW, enough to power over 1.3 million UK homes, Hornsea Project Two will become the world’s biggest wind farm, even surpassing the 1,200-MW giant Hornsea Project One, which DONG Energy is currently under construction.

Hornsea Project 2

Hornsea Project Two will be built 89 kilometers from the Yorkshire coast and is expected to be operational from 2022. The project will contribute significantly to DONG Energy’s ambition of reaching a total offshore wind capacity of 11-12GW by 2025.

At GBP 57,50/MWh ($76.36 USD/MWh), the strike price for the Contract for Difference (CfD) is 50% lower than the previous round of CfD allocations just two years ago, demonstrating the rapid reduction in cost across the industry.

“We’re delighted to be awarded a Contract for Difference for Hornsea Project Two, which is another important step towards fulfilling our vision of making offshore wind the most competitive form of electricity generation,” says Samuel Leupold, Executive Vice President and CEO of Wind Power at DONG Energy.

Hornsea Project Two will be built 89 kilometers from the Yorkshire coast and is expected to be operational from 2022. The project will contribute significantly to DONG Energy’s ambition of reaching a total offshore wind capacity of 11-12GW by 2025

“We have always promoted size as a key driver for cost,” adds Leupold. “The ideal size of an offshore wind farm is 800-1,500MW, and therefore it is natural that Hornsea Project Two will deliver record-low costs to society. At the same time, the low strike price demonstrates the cost saving potential of developer-built offshore grid connections, which in the UK is included in the project scope.”

DONG Energy is already constructing Hornsea Project One and has started the consultation process for Hornsea Project Three, underlining the huge potential of this area of the North Sea for offshore wind.

Cost-drivers enabling the bid for Hornsea Project Two

  • Scale: DONG Energy’s pipeline of construction projects across the UK (Race Bank and Walney Extension in 2018, Hornsea Project One in 2020 and Hornsea Project Two in 2022) creates economies of scale. And with 1,386 MW, Hornsea Project Two has the scale required to secure low costs per-MW of construction and low costs per MWh during a lifetime of operations and maintenance.
  • Risk reduction: DONG Energy already has several years of experience from developing Hornsea Project One in the North Sea. This reduces construction and operation risk of Hornsea Project Two.
  • Synergies: Operations and maintenance on both Hornsea projects will be conducted from DONG Energy’s new hub in Grimsby, which also serves other DONG Energy offshore wind farms on the UK east coast.
  • Maturing industry and technology: Innovation of offshore wind turbines, new installation equipment and methods, continuous improvements of foundation design, improved cables with higher capacity, and a growing and competitive supply chain.

“This is a breakthrough moment for offshore wind in the UK and a massive step forward for the industry,” says Matthew Wright, Managing Director for DONG Energy UK. “Not only will Hornsea Project Two provide low cost, clean energy to the UK, it will also deliver high-quality jobs and another huge boost to the UK supply chain.”

“Successive governments deserve great credit for providing the certainty for continued investment in offshore wind,” adds Wright. “Costs are falling rapidly, long-term and highly-skilled jobs are being created across the North of England and the UK supply chain is going from strength to strength. We’re now really seeing the benefits of this commitment to offshore wind and there is still so much more to come. Indeed, it has the potential to play a key part in the realization of the UK’s industrial strategy.”

With the allocation of the CfD, DONG Energy has now taken a Final Investment Decision on Hornsea Project Two. The information provided in this announcement does not change DONG Energy’s previous financial guidance for the financial year of 2017 or the announced expected investment level for 2017.
