Increased demand for home power generation at home and the benefits of the weaker pound for exports have led to strong growth in the small wind converter industry, reports the British Wind Energy Association (BWEA). Export revenues for 2008 doubled compared with 2007 and in the UK, small and micro wind turbines account for over 20 MW of installed capacity. The BWEA claims that given the right incentives, the sector has the potential to contribute 1.3 GW of installed capacity by 2020. Financial support for small wind rose last month to the allocation of two renewables obligation certificates (ROCs) for each megawatt hour of power generated, which can be cashed in with electricity retailers who must demonstrate compliance with legislation requiring them to finance green power. Compared with large scale wind, which boasts no significant UK turbine manufacturing capacity, the British small wind sector holds its own against European rivals.
