The world's first offshore floating wind farm has started to deliver electricity to the Scottish grid, providing power to approximately 20,000 households.
The 30MW Hywind Scotland wind farm, operated by Statoil in partnership with Masdar 25 kilometers offshore Peterhead in Aberdeenshire, Scotland, was officially opened today by First Minister of Scotland, Nicola Sturgeon.
“This marks an exciting development for renewable energy in Scotland,” First Minister Sturgeon said. “Our support for floating offshore wind is testament to this government’s commitment to the development of this technology and, coupled with Statoil’s Battery Storage Project, Batwind, puts us at the forefront of this global race and positions Scotland as a world centre for energy innovation.”
Irene Rummelhoff, executive vice president of the New Energy Solutions business area in Statoil, said, “Hywind can be used for water depths up to 800 meters, thus opening up areas that so far have been inaccessible for offshore wind.”
“The learnings from Hywind Scotland will pave the way for new global market opportunities for floating offshore wind energy. Through their government's support to develop the Hywind Scotland project, the U.K. and Scotland are now at the forefront of the development of this exciting new technology. Statoil looks forward to exploring the next steps for floating offshore wind.”
The onshore operations and maintenance base for Hywind Scotland is located in Peterhead, while the operations center is located in Great Yarmouth. Linked to the Hywind Scotland project Statoil and partner Masdar will also install Batwind, a 1MWh Lithium battery storage solution for offshore wind energy.
Battery storage has the potential to mitigate intermittency and optimize output.
Crown Estate Scotland leases seabed to renewables developers and works to encourage development and attract investment. Sian Wilson of Crown Estate Scotland said, “The [Hywind Scotland] project is a great success for the teams at Statoil and Masdar and for Scotland, where floating wind could really flourish due to our accessible deeper waters. We are committed to continuing our work to encourage floating offshore wind projects, which will in turn drive down costs, benefitting the whole sector—as well as the climate and consumers.”
Statoil noted that there have been significant cost reductions in both the onshore and bottom fixed offshore wind sectors in recent years. Floating wind is expected to follow a similar downward trajectory over the next decade, making it cost competitive with other renewable energy sources.
Rummelhoff said, “Statoil has an ambition to reduce the costs of energy from the Hywind floating wind farm to €40-60 €/MWh by 2030. Knowing that up to 80 percent of the offshore wind resources are in deep waters (+60 meters) where traditional bottom fixed installations are not suitable, floating offshore wind is expected to play a significant role in the growth of offshore wind going forward.”
Mohamed Al Ramahi, CEO of Masdar, said, “Hywind Scotland is showing that floating wind technology can be commercially viable wherever sea depths are too great for conventional fixed offshore wind power. This opens up a number of new geographies, and we are already looking at future opportunities with our partners, building on our existing international portfolio in onshore and offshore wind energy, and solar power.”
Hywind Scotland adds to Statoil’s U.K. growing presence. in Aberdeen more than 1,500 are employees in the final phase of commissioning the Mariner oil field, one of the largest upstream UKCS developments in the last 10 years, due to come onstream in 2018.
Statoil already has a sizeable renewables portfolio with an offshore wind portfolio with the capacity of providing more than 1 million homes with renewable energy. Statoil operates the Sheringham Shoal wind farm in the U.K., which has been in production since 2012.
The Dudgeon offshore wind farm in the U.K., also operated by Statoil has now been completed and is also in production. In 2016 Statoil also acquired 50 percent of the Arkona offshore wind farm in Germany, which will deliver power in 2019. Statoil recently announced the acquisition of a 40 percent share in the construction ready 162MW Apodi solar asset in Brazil.
