Policy 5.7 Renewable energy



A  The Mayor seeks to increase the proportion of energy generated from renewable sources, and expects that the projections for installed renewable energy capacity outlined in the Climate Change Mitigation and Energy Strategy and in supplementary planning guidance will be achieved in London.

Planning decisions

B  Within the framework of the energy hierarchy (see Policy 5.2), major development proposals should provide a reduction in expected carbon dioxide emissions through the use of on-site renewable energy generation, where feasible.

LDF preparation

C  Within LDFs boroughs should, and other agencies may wish to, develop more detailed policies and proposals to support the development of renewable energy in London in particular, to identify broad areas where specific renewable energy technologies, including large scale systems and the large scale deployment of small scale systems, are appropriate. The identification of areas should be consistent with any guidelines and criteria outlined by the Mayor.

D  All renewable energy systems should be located and designed to minimise any potential adverse impacts on biodiversity, the natural environment and historical assets, and to avoid any adverse impacts on air quality.

5.39  Use of renewable energy presents a significant opportunity to reduce carbon dioxide emissions, and its development will also contribute to the security of energy supply in London. Energy generated from waste provides a particularly significant opportunity for London to exploit in the future. Preference should be given to using advanced conversion technologies including anaerobic digestion, gasification and pyrolysis (see glossary) that have the potential to achieve greater efficiencies and carbon dioxide emissions savings.

5.40  The Mayor has outlined in the Climate Change Mitigation and Energy Strategy projections for the installation of different renewable energy technologies to increase London’s generation of both electricity and heat from such sources up to 2031.  These projections will be supported by supplementary planning guidance. The Government has adopted a UK wide target for 15 per cent of total energy to be generated by renewable sources by 2020, and these projections represent London’s contribution to this 2020 target and beyond. Further detail is set out in the Climate Change Mitigation Strategy and alterations to the Plan will be brought forward as appropriate.

5.41  Boroughs are encouraged to identify opportunities for developing renewable energy systems in their areas, including large scale systems. Where land is needed for the provision of renewable energy technologies, such as anaerobic digesters and biomass plants, boroughs should encourage this provision through their inclusion in development briefs and area action plans.  The Mayor’s supplementary planning guidance will set out broad guidelines to assist boroughs and, where appropriate, neighbourhoods, to define locations where stand-alone renewable energy schemes would be appropriate. The increased use of renewable heat will also significantly depend on the growth of heat networks. The Mayor and Boroughs will also encourage community-led initiatives for renewables and low carbon energy and examine how they can be supported through neighbourhood planning (see Policy 7.1).

5.42  Individual development proposals will also help to achieve these targets by applying the energy hierarchy in Policy 5.2.  There is a presumption that all major development proposals will seek to reduce carbon dioxide emissions by at least 20 per cent through the use of on-site renewable energy generation wherever feasible. Development proposals should seek to utilise renewable energy technologies such as: biomass heating; cooling and electricity; renewable energy from waste; photovoltaics; solar water heating; wind and heat pumps. The Mayor encourages the use of a full range of renewable energy technologies, which should be incorporated wherever site conditions make them feasible and where they contribute to the highest overall and most cost effective carbon dioxide emissions savings for a development proposal.
