Community Energy

What’s community energy?

Our understanding of a community energy project is one where communities have a high degree of control and ownership (Walker and Devine-Wright, 2008). The Department of Energy and Climate Change definition stated that such projects involve renewable energy generation, energy efficiency initiatives, demand-side response, collective purchase or some combination of these (2015). We widen that definition to include projects that are engaged with energy innovations and experimentation, as well as awareness raising and energy education.

We also recognise the importance, not only of the many local communities involved in energy projects, but also the city-wide networks that strengthen community projects.

  • Whilst there are many types of communities, there are also many different ways of working ‘with energy’. For example, most people associate ‘community energy’ with renewable energy generation – which in cities is predominantly solar. However, there is a growing number of technologies associated with energy generation – including tidal, anaerobic digestion, combined heat and power, heat pumps and wind. In London, solar currently leads the way, but we believe that experimentation is key; we will continue to support solar but are also excited to assist with other technologies. 

    Solar in London

    “Community energy groups in London currently own and operate 748 kWp of solar PV situated on churches, social housing blocks and schools that have been financed through the purchase of shares by members of the community.” 

    Community Energy London report Realising the Potential’ July 2017


    Despite the many set backs that the solar industry has faced due to inconsistent government policies, there are many successful community solar projects – even in London where the property market and access to space is extremely competitive. See below for examples of successful community solar projects in London. 

    Greenpeace outline how easily solar could contribute to powering every home in the country – and London needs to generate as much energy as possible onsite. This would help make the city more economically and environmentally sustainable, not to mention help relieve those living with – and dying from – fuel poverty.

    However, the London Assembly Environment Committees  Bring Me Sunshine How London’s homes could generate more solar energy (October 2015) noted that London, “has the lowest amount of installed solar power capacity of any region in the UK, despite being the most affluent and populous part of the country, and having a favourable climate by UK standards.”

    Community Energy groups in London can lead the way

    Community groups have lists of projects that were ready to go, but stopped when Government policies made them no longer viable. Community Energy London’s ‘Realising the Potential’ July 2017 points out current barriers and identifies the profile of buildings that have proved most suitable for solar installations.

    Buildings that are suitable for solar installation usually require, stability of tenure, large roofs and high electricity usage, e.g. schools, places of worship and public buildings.

    Repowering London/ Brixton Energy 

    Repowering have set up four community solar projects on social housing:

    Brixton Energy Solar 1 – The project involved the installation of a 37.24kWp solar power station on the roof of Elmore House on the social housing Loughborough Estate in Brixton in March 2012.
    Brixton Energy Solar 2 – installed 45kWp of solar electric (photovoltaic) panels on the roofs of Styles Gardens, five of the housing blocks in the Loughborough Estate, Brixton in Oct 2013.
    Brixton Energy Solar 3 – installed 52kWp of solar PV panels on the roofs of Roupell Park estate in Brixton. The panels went live in September 2014.
    Banister House Solar  – supported by Hackney Energy, the project generates 102kWp of renewable, community-owned electricity for the Banister House Estate and residents, from January 2014.


    Schools Energy Coop 

    The group helped schools in London install solar panel systems on schools free of charge, using crowd funding: 

    Castlebar School installed 19.76kWp of solar in 2016

    Gospel Oak Primary School – installed 29.64kWp of solar in 2016 Acland Burghley – installed 48.36kWp

    Please get in touch if you belong to another London group that has installed solar.

  • Some groups don’t deal with energy generation at all, preferring to focus on energy efficiency projects in their area, such as promoting the use of LEDs. Energy efficiency is a key element of a renewable energy project: the more efficient a building, the more feasible it is to power the building with renewable energy. To put energy efficiency into a national context, the much disputed nuclear station, Hinkley Point C, was predicted to generate 7% of the UK’s electricity requirements. However, energy experts predict that 7% of the demand could be simply saved through energy efficiency measures – meaning no need for unproven and potentially dangerous nuclear technologies.

  • Arguably this is the most important part of a community energy project’s work. Whilst local authorities and even the business sector are starting to engage with renewable energies and efficiency measures, it is the community energy sector that has been most successful at educating the public in ways that effect behavioural change. This is because community groups tend to be thought more trustworthy than other organisations, and so they are well placed to “change hearts and minds”, to educate and inspire.
