Wind energy deployment rates downgraded
Deployment rates for both onshore and offshore wind are predicted to be slower than previously expected over the coming years.
Analysis on the deployment of renewable energy, conducted by Arup and published by the Department of Energy and Climate Change, suggested by 2020 the technologies could provide 35 percent of generating capacity.
Onshore wind was said to have "significant potential", of around 17.3GW by 2035, but deployment is not expected to be as fast as previously thought and existing 2020 targets can only be reached under a "high ambition scenario".
This was said to be due to "planning and grid constraints".
In the next five to ten years, deployment rates for offshore wind are also expected to be slower, which is due to the phasing of the larger projects after 2015.
Offshore wind is expected to generate 41GW by 2030 under a moderate scenario, while estimates for wind, hydro, marine and solar PV power were not revised from those calculated in previous studies.
Simon Power, technical director for the study at Arup, said: "This report is not designed to say one solution is better than another.
"Rather, it provides the government and other stakeholders with a comprehensive evidence base to make economic and political decisions."
