Capturing the value of community energy

Energise Sussex Coast and South East London Community Energy are set to benefit from a new business collaboration led by Colin Nolden and supported by PhD students Peter Thomas and Daniela Rossade. This is funded by the Economic and Social Research Council with match funding provided by Community Energy South from SGN. In total, £80,000 has been made available from the Economic and Social Research Council Impact Accelerator Account to launch six new Accelerating Business Collaborations involving the Universities of Bath, Exeter and Bristol. This funding aims to increase capacity and capability of early career researchers and PhD students to collaborate with the private sector. Match funding from SGN (formerly Scotia Gas Network) provided by Community Energy South for this particular project will free up time and allow Energise Sussex Coast and South East London Community Energy to provide the necessary company data and co-develop appropriate data analysis and management methodologies.

The Capturing the value of community energy project evolved out of the Bristol Poverty Institute (BPI) interdisciplinary webinar on Energy and Fuel Poverty and Sustainable Solutions on 14 May 2020. At this event Colin highlighted the difficulty of establishing self-sustaining fuel-poverty alleviation business models, despite huge savings on energy bills and invaluable support for some of the most marginalised segments of society. Peter also presented his PhD project, which investigates the energy needs and priorities of refugee communities. With the help of Ruth Welters from Research and Enterprise Development and Lauren Winch from BPI, Colin built up his team and concretised his project for this successful grant application.

The two business collaborators Energise Sussex Coast (ESC) and South East London Community Energy (SELCE) are non-profit social enterprises that seek to act co-operatively to tackle the climate crisis and energy injustice through community owned renewable energy and energy savings schemes. Both have won multiple awards for their approach to energy generation, energy saving and fuel poverty alleviation.

However, both are also highly dependent on grants from energy companies such as SGN with complicated and highly variable reporting procedures. This business collaboration will involve the analysis of their company data (eight years for ESC, ten years for SELCE) to take stock of what fuel poverty advice and energy saving action works and what does not, and to grasp any multiplier effects associated with engaging in renewable energy trading activities alongside more charitable fuel poverty alleviation work.

Benefits for ESC and SELCE include the co-production of a database to help them establish what has and has not worked in the past, and where to target their efforts moving forward. This is particularly relevant in the context of future fuel-poverty alleviation funding bids. With a better understanding of what works, they will be able to write better bids and target their advice more effectively, thus improving the efficiency of the sector more broadly.

It will also help identify new value streams, such as those resulting from lower energy bills. Rather than creating dependents, this provides the foundation for business model innovation through consortium building and economies of scale where possible, while improving targeted face-to-face advice where necessary. It will also explore socially distant approaches where face-to-face advice and engagement is no longer possible.

With a better understanding how and where value is created, ESC and SLECE, together with other non-profit enterprises, can establish a platform cooperative while creating self-renewing databases which enable more targeted energy saving and fuel poverty advice in future. Such data also facilitates application for larger pots of money such as Horizon2020, and the establishment of a fuel poverty ecosystem in partnership with local authorities and other organisations capable of empowering people instead of creating dependents. This additional reporting will capture a wider range of value and codify it to be submitted as written evidence to the Cabinet Office and Treasury at national level, while also acting as a dynamic database for inclusive economy institutions and community energy organisations at regional and local level.


Dr Colin Nolden is a Vice-Chancellor’s Fellow based on the Law School, University of Bristol, researching sustainable energy governance at the intersection of demand, mobility, communities, and climate change. Alongside his appointment at the University of Bristol, Colin works as a Researcher at the Environmental Change Institute, University of Oxford. He is also a non-executive director of Community Energy South and a member of the Cabot Institute for the Environment.

Peter Thomas is a University of Bristol Engineering PhD student and member of the Cabot Institute for the Environment investigating access to energy in humanitarian relief by combining insights from engineering, social sciences, and anthropology.

Daniela Rossade is a University of Bristol Engineering PhD student investigating the transition to renewable energy on the remote island of Saint Helena and the influence of renewable microgrids on electricity access and energy poverty.

Converting probabilities between time-intervals

This is the first in an irregular sequence of snippets about some of the slightly more technical aspects of uncertainty and risk assessment.  If you have a slightly more technical question, then please email me and I will try to answer it with a snippet. Suppose that an event has a probability of 0.015 (or 1.5%) of happening at least once in the next five years. Then the probability of the event happening at least once in the next year is 0.015 / 5 = 0.003 (or 0.3%), and the probability of it happening at least once in the next 20 years is 0.015 * 4 = 0.06 (or 6%). Here is the rule for scaling probabilities to different time intervals: if both probabilities (the original one and the new one) are no larger than 0.1 (or 10%), then simply multiply the original probability by the ratio of the new time-interval to the original time-interval, to find the new probability. This rule is an approximation which breaks down if either of the probabilities is greater than 0.1. For example

1-in-200 year events

You often read or hear references to the ‘1-in-200 year event’, or ‘200-year event’, or ‘event with a return period of 200 years’. Other popular horizons are 1-in-30 years and 1-in-10,000 years. This term applies to hazards which can occur over a range of magnitudes, like volcanic eruptions, earthquakes, tsunamis, space weather, and various hydro-meteorological hazards like floods, storms, hot or cold spells, and droughts. ‘1-in-200 years’ refers to a particular magnitude. In floods this might be represented as a contour on a map, showing an area that is inundated. If this contour is labelled as ‘1-in-200 years’ this means that the current rate of floods at least as large as this is 1/200 /yr, or 0.005 /yr. So if your house is inside the contour, there is currently a 0.005 (0.5%) chance of being flooded in the next year, and a 0.025 (2.5%) chance of being flooded in the next five years. The general definition is this: ‘1-in-200 year magnitude is x’ = ‘the current rate for eve

Coconuts and climate change

Before pursuing an MSc in Climate Change Science and Policy at the University of Bristol, I completed my undergraduate studies in Environmental Science at the University of Colombo, Sri Lanka. During my final year I carried out a research project that explored the impact of extreme weather events on coconut productivity across the three climatic zones of Sri Lanka. A few months ago, I managed to get a paper published and I thought it would be a good idea to share my findings on this platform. Climate change and crop productivity  There has been a growing concern about the impact of extreme weather events on crop production across the globe, Sri Lanka being no exception. Coconut is becoming a rare commodity in the country, due to several reasons including the changing climate. The price hike in coconuts over the last few years is a good indication of how climate change is affecting coconut productivity across the country. Most coconut trees are no longer bearing fruits and thos
