In this section, we set out two examples of Net Zero/energy policy and governance that fit within the radical incrementalist and mission led paradigms, for each we question how and to what degree they challenge the rational actor assumption of energy consumers and whether they can be best understood through a relational lens.
‘Solar for Flats’: Radical Incrementalism for Britain’s flat dwellers
In recent years, there has been an expansion in local energy and local energy business models based on the premise that, as smart meters and distributed energy resources like solar power, heat pumps, battery storage, and EVs get cheaper, they will be able to form Smart Local Energy Systems (SLES) which optimise these assets together. A great deal of analytical effort and innovation funding has been expended on trying to make SLES constellations work in the UK (
Ofgem 2021;
UKRI Innovate UK n.d.). Most of these trials retain the conception of the energy consumer as a utility maximiser wishing to become their own energy micro-entrepreneur (
Community Energy England 2024;
Laes & Bombaerts 2022), ready to deploy their smart energy systems towards individual gain. This cannot work for people in certain types of dwelling or tenure, who do not own the objects that allow for SLES. More recently still, innovation funding has started to take account of these issues and multiple trials have been established serving lower-income homes.
1 Some of these have progressed under innovation funding trials and others have been accommodated by Ofgem’s regulatory sandbox service, which investigates the changes needed to energy market regulations to allow innovation to happen.
The example of radical incrementalism we want to highlight here is where Emergent Energy, a UK company, worked through the supply licensing regime and Balancing and Settlement Code to discover where and how a solar microgrid could be used to ensure people who live in flats could benefit from rooftop solar energy. England and Wales has over 5.4 million flats (
Office for National Statistics 2023) and hitherto there have been few opportunities for the occupants of flats to benefit from rooftop solar energy.
This is largely because energy system regulation viewed flats as though they were any other home with a meter, beyond which energy was being transacted over a public network. Regardless of them living in a communal building, the energy system treated them as atomised household units without proximity to each other (methodological individualism). There was no space in the regulations to recognise the opportunities of multi-occupancy buildings for solar rooftops, or any recognition that these housing types were virtually absent from the energy transition. This was until a company was driven to expand access adopted ‘Radical Incrementalism’
2 to solve the problem.
Emergent Energy worked with the regulator Ofgem (
2020) through the regulatory sandbox process, and with Hackney Light and Power (
Hackney Government 2024) to understand the barriers to provisioning a microgrid and metering and billing infrastructure to flats to enable residents in Hackney to ‘self-consume’ solar energy generated on their block. Critically for such tenants, there would be no up-front capital involved. The council would own the equipment and repay the capital through energy bill payments of the residents subscribing to the new solar tariff. Current expectations are that the scheme will pay for itself while enabling the average consumer to achieve a 20 per cent bill saving.
To allow this trial to take place, however, Ofgem needed to grant Emergent derogations from the License Condition 13A.4 of the Electricity Distribution License and temporary consent not to comply with License Condition 14 B to ensure that charges could be levied appropriately for the different users of the new microgrid (
Ofgem 2023). Emergent also required a sandbox derogation from several metering codes of practice found in the Balancing and Settlement Code (
Ofgem 2022). This ensured that the customers on the metered network gained better access to third-party suppliers. At the time of writing, Hackney Council has just closed the Green Investment round 1 offer (August 2024) and raised £600,000 through community municipal bonds (
Davis & Cartwright 2019), which are expected to be used for extending the Emergent scheme solarising council-owned flats (
Abundance 2024).
The derogations granted were both aimed at ensuring that competition between suppliers could still take place, and that the ability to accurately meter and charge all users for discrete elements of the system, such as the exempt distribution network, could be retained. By incrementally unpacking which system codes and licences were affected, Emergent and Ofgem were able to identify derogations allowing the trial to take place and then work towards adopting these derogations into the licensing regime so that others could replicate the model.
3The experience of Emergent Energy and Hackney Light and Power shows that, to enable a ‘radical’ shift in the opportunities for Net Zero participation in the UK, specific attention needs to be paid to energy system regulation and governance. Where most individuals can only engage with solar on an atomised ‘entrepreneurial’ basis by buying solar for their own home and trading surplus, the Emergent and Hackney model makes space for collective participation in a communally (in this place municipally) owned asset, and it extends that opportunity to geographic and socio-economic groups that have hitherto been marginalised. This means the residents of flats in Hackney and, as the model proliferates, across Britain can start to build relational packages around positive, locally meaningful engagements with Net Zero technologies. This model may be extendable to other dense forms of mixed-tenure dwellings like terraces and central urban areas, which have historically benefitted much less from incentives such as the feed-in tariff. This may be the next incremental step in extending the benefits of Net Zero to marginalised or excluded communities which, in Torsten Bell’s formulation, can be done quickly with visible positive results on people’s daily lives.
Note two specific things about the work done here: First, many of the changes to regulation that were needed were made to retain the function of competitive retail energy markets, which are already seen to be failing lower-income disengaged homes. Second, Emergent Energy went beyond standard ‘market-correcting’ energy policy, which is blind to people and place, and established its own relational approach to include a specific geographic and socio-economic community in the energy transition. If Radical Incrementalism is to retain its ‘radical’ element, it needs to continue to pursue change that surpasses ‘market-correcting’ energy policy and Emergent’s use of the approach is a good example.
Universal Basic Energy, a ‘Mission Led’ energy policy
If Mission Led governance means orienting economic systems to public purpose, the experience of low income and vulnerable consumers in the retail energy market should be high priority. As of 1 July 2024, National Energy Action estimates that the number of households in fuel poverty is close to 5.6 million, each unable to afford sufficient warmth (
Middlemiss 2017;
National Energy Action 2024). Cold homes kill people; excess winter deaths attributed to cold homes and fuel poverty range between 3000 and more than 9000 people per year (
E3G 2018). For those who survive, there are a range of physical and mental health effects resulting from fuel poverty that place significant additional stress and costs on health and social care services. There are multiple policy packages that aim to reduce the burden of energy bills on the poorest homes, but even including the impacts of these policies, the average fuel poverty gap (the increase in incomes or decrease in fuel bills needed to escape fuel poverty) was £417 per fuel-poor home or £1.3 billion in aggregate in 2023 (
Hinson & Bolton 2024). With energy poverty so entrenched, there is some doubt that energy policy alone can make up for other systemic inequalities (
Middlemiss 2020).
Emerging in dialogue with the wider debate on ‘Universal Basic Income’ (
Bidadanure 2019), the idea of Universal Basic Services guarantees everyone a series of public services, such as health, shelter, food, education, information, access to legal services, and transport. These together are argued to provision a basic social floor for everyone (
Portes et al. 2017). Extending the notion to analyse energy specifically, the New Economics Foundation proposes a ‘National Energy Guarantee’ where a minimum essential volume of energy is provided free, and a premium is applied to higher levels of usage (
Chapman & Kumar 2023). Advocates of the National Energy Guarantee describe it as a dividend on our national mission to Net Zero and are explicitly targeting Labour’s clean power mission as a way into Whitehall energy policy (
Taylor 2024).
The idea works by a price premium being applied at the top end of household energy consumption, which is designed to pay for the Universal Basic at the bottom. This is argued to have the dual advantage of lifting millions out of fuel poverty while incentivising energy-efficiency improvements for those who are able to pay. The NEF (National Energy Foundation) analysis suggests an average gain of £250 among the poorest 30 per cent of households, which is 60 per cent of the existing fuel poverty gap.
4The notion that energy sufficiency could be provisioned via a Universal Basic Energy model has to assume that the higher users will be locked into the supply relationship and unable to switch away to a different tariff structure. While we have stated that the UK is an outlier in having a fully competitive retail energy market, evidence from countries around the world that have implemented rising block tariffs (similar structures to a National Energy Guarantee) shows that positive effects on affordability are common (
Foster & Witte 2020). Many of the counter-arguments to Universal Basic Energy and rising block tariffs are based on experience from outside Europe or are theorised not observed (
Chapman 2024). There is, in short, a powerful distributional case for adopting a Universal Basic Energy programme.
While the work of NEF presents a compelling case, the implications for energy system governance are profound. To achieve a National Energy Guarantee, a cornerstone of UK energy policy would need to be altered: retail market competition. The ability of a domestic consumer to switch supplier is enabled by the Electricity Act 1989 and held in the licensing regime administered by
Ofgem (2024a). The standard licence conditions contain provisions for all domestic energy consumers to make and end supply contracts with licensed parties. The current standard time for being able to switch energy supplier is 5 days (
Ofgem 2024b).
Implementing a Universal Basic Energy programme would mean re-casting the energy retail market. A rising block tariff model assumes that prices are set the same for everyone. Therefore, the notion of retail energy utilities competing on cost would have to be replaced. This would mean reconstituting the entire systems architecture, from who is responsible for metering and billing, to how network costs and charges are recovered, how the system is balanced and settled. From a distributional justice perspective, the National Energy Guarantee scheme is persuasive, but from a system governance perspective it would mean a seismic re-organisation of the system. From our relational economic sociology perspective, this too would require a whole new set of social relations to emerge around energy as an entitlement as opposed to a bought commodity, the energy system as a tool of social redistribution as well as one of needs provision.
Finally, as we move to a market where when we use energy can be as important as how much we use, the rising block tariff model would have to evolve to accommodate shifting price signals, which it is unsuited to doing. Once again, the trade-off between allowing innovation to thrive at the ‘engaged’ end of the market and the distributional outcomes of this becomes paramount. Enabling low-income homes to benefit from smart tariffs must become a priority for UK retail energy market policy.
