Community Energy in the UK

Estimated reading time: 3 minutes, 57 seconds

The Community Energy sector has been challenged since the Government’s new position on incentives for renewables. This is the chance for the United Kingdom to explore the new model of local energy communities that are possible thanks to smart and microgrids, energy sharing in a peer-to-peer dynamic and technology like smart meters and SNOCU units.

Since the end of the Feed-in Tariff Scheme (FITS) last year, the community energy sector in the United Kingdom has been struggling. At the same time, the lack of support from government incentives also creates an opportunity for new strategies and business models to thrive.

Let’s see how community energy works and the state of the sector, according to the last official data.

Solar photovoltaic power generation in the United Kingdom

According to the data published by statista last February, solar energy generation in the United Kingdom increased rapidly, especially between 2011 and 2018, thanks to a mix of technological development and launch of the government’s Feed-In Tariff scheme (FITs) in 2010. The last official data on electricity and heat production from photovoltaic generation recorded 12,857 GW hours in 2018 with a cumulative installed capacity of 13,098 MW.

This growth is also due to the contribution of the Community Energy sector, which evolved alongside solar panel distribution. Its exact size is unknown but around 300 community organisations have been counted, managing different kinds of community-owned renewable initiatives, not all solar. The first community-owned renewable project connected to the grid was a wind farm in Cornwall in 1991.

Definition of Community Energy

According to UKERC research, Community Energy includes any energy project completely or partially controlled or owned by a group of people identifiable as a community, for instance co-operatives. It also includes any project with two or more of the following features:

  • The project is hosted on a site owned or managed by the community group.
  • The organisation is a community benefit society, where members share control democratically and profits are distributed in the community.
  • Community members have an active role in the project, for example producing energy with a domestic solar photovoltaic panel and sharing it with other members through specific local supply arrangements.

The UK Government underlines that the keyword of Community Energy is “local”: local engagement, leadership, control, and outcomes. Local stakeholders own or control the majority of the sustainable energy projects, voting remains democratic and social and economic benefits are shared locally.

Most of the energy community projects are focused mainly on:

  • energy consumption and waste reduction
  • management, generation and purchase

The benefits of these projects are both economic and social: community energy enhances local acceptance and awareness of renewable energy sources and emphasizes the importance of decreasing fossil-based energy consumption. At the same time, local communities have the chance to access energy at a lower cost, to maximise energy efficiency and to create local jobs.

Regardless of whether you live in a flat in the city centre with a shared rooftop or a terraced house in the countryside, you can monitor and analyse your energy consumption and the performance of your PV and ESS (Energy Storage System), balancing the energy you share with other community members. In any of these scenarios, the benefits of sharing energy can be further improved by installing SNOCU units and joining the Regalgrid platform.

Community Energy in England, Wales & Northern Ireland

The State of the Sector 2019 report by Community Energy England collects data for EnglandWales and Northern Ireland and counts 275 Community Energy Organisations all across these regions. 136 of them are Community Benefit Societies, 42 are Co-operatives and 22 are Charity Organisations.

In 2018, the sector was still dominated by electricity generation, with a total generation capacity of 168 MW, composed of:

  • 4 MW wind power
  • 3 MW solar PV
  • 2 MW hydroelectric

These projects require a decentralised system connected to the distribution grid. Organisations often reinvest incomes in low-carbon initiatives. Most of the projects funded are actually related to energy efficiency: energy switching, smart-meter installation, energy-efficient lighting and insulation.

Other communities deal with energy storage, heat generation (1.96 MW of generation capacity) and low-carbon transport.

Community Energy in London

London is a city that is particularly active in community energy. The specific report shares some available data for 2018. The Non-Profit Organisation that has gathered the data mentions 35 projects under way, an installed solar capacity of 475 kW and crowdfunded investment reaching over £600,000.

For instance, Repowering is developing a community-owned project, working with local people. They are planning to install solar PV panels allegedly with a capacity of 50 kW on rooftops in the Middlesex Street Estate in the Portsoken ward, and to fund this £48,000 project by selling shares to community members and thanks to donations from corporations which want to increase sustainable actions.

Community Energy in Scotland

In Scotland, the latest report was published in January 2020, presenting data relative to June 2019. At that time 43 organisations were active and 58 more were in other stages of development. The operational capacity of active communities was 82 MW. Most of the energy was generated by wind farms (44% of operational capacity) and biomass systems (26%). Solar photovoltaic represents only 8% of the total capacity, but it is the most common choice for domestic systems (8,650 installations).


Energy communities play an important role in the UK energy market and progressively in many other countries. Their contribution to expansion of DERs (Distributed Energy Resources) is significant and the number of communities in operation demonstrates that a good level of efficiency can be reached through decentralised operation, management and consumption of energy from on-site renewables.

Modifications to subsidization schemes require new efforts to keep organizations running.

The Regalgrid® platform is a comprehensive package of services to optimise energy sharing within communities. Proprietary algorithms perform dynamic optimization of individual and collective self-consumption. Using its local gateway SNOCU, Regalgrid cloud architecture performs real-time monitoring of PV production, ESS SoC and loads of all members of the community, whether they are consumers, prosumers, householders or tenants. The system communicates with smart HVACs and EV chargers for full control of local energy assets, whichever the manufacturer of your hardware. The same applies for inverters and storage devices: Regalgrid is hardware neutral.

Thanks to the Regalgrid® platform, UK energy communities can be transformed into smart, digital grids that maximise the contribution from DERs to the benefit of all members.
