The North Sea

  • The North Sea is one of the most favourable areas in the world for the large-scale development of offshore wind. All year round, excellent wind conditions in the North Sea put Europe at the forefront of harnessing the vast energy production potential of the wind. The European Wind Energy Association predicts that a capacity of as much as 150 GW will come from offshore wind installations by 2030.

    The shift to renewable energy in the UK, comes after the UK`s oil and gas production has shrunk by more than half since it peaked in 1999. Production from the UK’s continental shelf has fallen at an annual rate of around 6.2% over the past 23 years.

    The UK has about a third of the potential offshore wind farm sites in Europe (more than any other nation) off Scotland and in the North Sea. Drawing on offshore energy expertise and government mandates to increase the amount of power derived from clean energy, the countries around the North Sea, led by the UK, plan to develop 35.5 GW of offshore wind projects by 2020 compared with 2.9 GW today. The total cost of the increase will be EUR 127 billion, and the facilities will provide 3.2% of the European Union’s electricity demand.

    Germany, which began phasing out its nuclear power plants following the 2010 disaster in Japan, wants to increase its offshore wind production to 10,000 megawatts, with turbines contributing as much as 5.7% of gross energy production. France is aiming to go from no offshore wind production to 6,000 megawatts in eight years. Denmark has installed wind power capacity of 3,955 MW, which meets about a fifth of the nation's total electricity needs, the highest proportion in the world. Almost 35% of Danish energy needs will come from renewable energy sources and nearly 50% of our electricity consumption will come from wind power by 2020.

    In total, at least EUR 114 billion, and up to EUR 152 billion, of investment is required in the next eight years to build as much as 35,500 megawatts of offshore wind in the North Sea.


     

  • The offshore wind industry is flourishing. The European Environment Agency%u2019s (EEA) state in a study that European offshore wind power%u2019s economically competitive potential in 2020 is 2,600 TWh, equal to between 60% and 70% of projected electricity demand, rising to 3,400 TWh in 2030, equal to 80% of the projected EU electricity demand. In terms of annual installations, offshore wind energy is where onshore wind was in the early 1990s. Most of the 1.5 GW installed today is in the North Sea, with Denmark, Germany and the Uk as leading installation countries, but with emerging activity in the Netherlands, France, Italy and Spain. The sector will shortly leave the demonstration phase to enter a phase of strong industrial growth. In 2008, over 1 MW was installed per day, reaching a total of 1,471 MW worldwide by the end of the year. There are over 100 GW of offshore wind projects already being planned and EWEC estimate that 40 GW of offshore wind will be built in the EU by 2020 and 150 GW by 2030. The 2020 target implies an average annual market growth of 28% over the coming 12 years. The 2020 target would avoid 85 tonnes of CO2 and produce 148 TWh of energy per year, equal to between 3.6% and 4.3% of EU electricity consumption, depending on the development in electricity demand. The offshore wind sector is an emerging industrial giant. But it will only grow as fast as the tightest supply chain bottleneck. It is therefore vitally important that these bottlenecks are identified and addressed so as not to constrain the industrial development. Turbine installation vessels, substructure installation vessels, cable laying vessels, turbines, substructures, towers, wind turbine components, ports and harbors must be financed and available in sufficient quantities. In the coming years, the main focus will be on standardizing the installation processes and developing dedicated offshore turbines from a dedicated supply chain. Reaching 40 GW of offshore wind energy by 2020 will mean manufacturing, installing and operating approximately 10,000 wind turbines, which corresponds to an average of three to four offshore turbines being installed per working day over the next 12 years. Currently, the wind power industry installs 20 onshore wind turbines in the EU per working day. Developing a new European offshore industry is a challenge, but the development of onshore technology and markets serves as a strong indicator and benchmark for what can be achieved. This industry will also develop in partnership with related industries, such as the oil and gas sector, the shipbuilding industry and the steel sector, and be a driver for their future development. Offshore wind energy provides an historic opportunity to create a new heavy industry in which Europe is a technology leader. The exciting future developments depend on an offshore grid being put in place to give Europe a pan-European electricity super highway. In addition, strong and sustained political support and action from Europe%u2019s policy-makers will allow a new, multi-billion euro industry to be built. To date, all fully operational offshore wind farms are in Europe. However, both the US and China in particular are determined to exploit their offshore wind potential, providing European companies with significant opportunities for manufacturing and technology exports, experienced developers, project planners, infrastructure experts, and installation equipment.
