In the summer of 2011, resources. Studies show that, as a the progressive deployment of offshore the UK government published the nation, the UK has the most favourable wind which, alongside other renewable Electricity Market Reform (EMR) conditions for offshore wind power energies, is expected to play a crucial white paper9 (see sidebar on page generation in Europe and perhaps role in attaining these challenging 9). The EMR seeks to adopt a series in the world1. According to industry objectives. To date, these policies of framework initiatives to provide association RenewableUK (formerly have proven effective in attracting long-term, comprehensive and targeted the British Wind Energy Association), investment and supporting the sector’s support for low-carbon generation and the electricity generation potential of growth, as evidenced by the rapidly renewable technologies. Currently, the UK offshore wind alone2 could amply increasing capacity and electricity principal incentive supporting offshore exceed the country’s total electricity production of offshore wind, as well as wind development is the Renewables demand requirements3. by the diversity of investors. Installed Obligation (RO, see sidebar on page capacity of offshore wind turbines 9), but other support mechanisms This plentiful source of clean and has more than doubled since 2008, (such as the proposed feed-in-tariffs renewable energy is a key piece of the reaching some 1.3 gigawatts (GW) with contracts for difference) are UK’s strategy to meet its ambitious in 20106, or about 1.5 percent of the expected to bring additional support. climate change and renewable energy UK’s total generation capacity, and commitments.

In stark ‘Renewable Energy Strategy lead contrast to the two previous rounds, scenario’ suggests that, by 2020, about the average project size in Round 3 was 30 percent of electric power could come approximately 1 GW. Construction has from renewable sources, compared to already begun for one of these mega- around 6.7 percent in 201016. Offshore projects, and an additional 11 mega- wind will have a central role in delivering projects are in the planning stages (see those ambitious objectives. Section 1.3).
