‘Rethinking heat’ is a thought provoking discussion paper that challenges policymakers to apply whole system thinking to ensure that increasing the deployment of heat pumps delivers value for consumers and the overall energy system.

The paper explores the existing evidence base and includes new analysis to establish whether there is a greater scope for use of ground source heat pumps (GSHPs) to decarbonise heat than previously assumed, along with assessing benefits that could be derived from a higher level of GSHPs deployed where heat is electrified.

Key findings from the paper
Regen’s analysis suggests that supporting the deployment of more GSHPs in a net zero scenario could:

  1. Unlock new business models that separate the capital cost of ground array from the upfront cost of installing the GSHP.
  2. Enable flats and terraced houses that do not have large gardens (representing 11m homes, 49% of housing) to be suitable for GSHP.
  3. Make GSHP costs comparable with ASHP costs and other low carbon solutions.
  4. Reduce peak electricity demand by 10% in a scenario with 20m heat pumps deployed.
  5. Enable minimised running costs through flexibility in domestic heat demand.
  6. Support UK manufacturing and develop more jobs in the supply chain.

Project duration: March 2020 – March 2022

Regen is a partner in a new £3 million Innovate UK-funded project to deliver a detailed design of a smart local energy system for Rugeley Town in Staffordshire and its local area, including the 2,300 houses being built in the former ENGIE Rugeley coal-fired power station. The post-industrial town, and the large brownfield development, is an opportunity to assess the options for a smart local energy system, using proven technologies at scale. This project will focus on user-centric approaches to engagement, business models and marketplace design, bringing together a number of leading organisations that are delivering solutions in the heat, transport and power sectors.

The funding secured is part of the UK Government’s (Department for Business, Energy & Industrial Strategy) £21m Detailed Design of Smart Local Energy Systems programme, part of a wider Industrial Strategy Challenge Fund programme called Prospering from the Energy Revolution.  It aims to create a pipeline of highly innovative, ambitious and investable local UK energy systems that will be ready to roll out across the country over the next decade.

Regen is leading on the policy and regulation work package, reporting and collating the latest changes and the impact on the Zero Carbon Rugeley project. We are also supporting other partners on the business models, buildings and user-centric design work packages.

Project duration: July 2017 to September 2019

Regen’s whole-system thinking is seeking to understand how both the electricity and gas networks will evolve, in a decentralised and decarbonised UK energy system. Building on the growth scenarios work Regen has undertaken for WPD and other DNOs, Wales and West Utilities (WWU) commissioned Regen to develop a methodology to create regional growth scenarios to support long term demand and investment planning for the gas network.

 

The development of this methodology used common assumptions and approaches that Regen developed for electricity network scenarios, but also developed an approach that was bespoke for sources of demand and supply connected to gas distribution networks. The scenarios focus on the evolution of heat demand, delivery technologies and fuels, the growth of gas fired power generation and the changing gas supply mix, including the introduction of hydrogen and injection of biomethane.

WWU used the outputs of this assessment of their network, to inform their business plan submission to Ofgem in 2019.

Project duration: July 2019- July 2020

Regen is supporting the Bristol City Council Energy Service on its heat network delivery, by providing project management support, funded by the Heat Networks Delivery Unit (HNDU).

Heat networks (also known as district heat) are networks of underground pipes that carry hot water and supply heat from a central source to consumers. The central heat source is known as an energy centre and many solutions can be used to generate heat. Across Bristol, networks are being designed to be low carbon.

Since July 2019, Regen has been embedded in the energy infrastructure team, providing sector knowledge and project management expertise. We are responsible for managing and critiquing feasibility studies, engaging with internal and external stakeholders and ensuring the successful delivery of projects with a view to increasing the build-out of low carbon heat networks across Bristol, in line with the Council’s declaration of  Net Zero by 2030.

Project duration: May 2018 – June 2020

Zero Energy Buildings Catalyst (ZEBCat) is a three year, European Regional Development Funded (ERDF) programme that aims to help enterprises interested in whole house retrofit to engage with this growing market.

The programme ran until June 2020 and:

  • Undertook the whole-house retrofit of homes in Devon, using the innovative Energiesprong approach
  • Delivered significant energy savings on a difficult to treat public building in Exeter
  • Supported at least 80 enterprises in Devon to engage with new models of delivering whole house retrofit at scale

The project partners are Devon County Council (Lead), Regen, Energiesprong UK, Exeter City Council, North Devon Homes and Sanctuary Housing. Each of the social landlord partners provided homes in Devon to be retrofitted as part of the programme, during 2018 and 2019.

Zebcat

Reinventing Retrofit

The ZEBCat programme commissioned The Green Alliance to produce a report outlining how the Energiesprong approach could be used to help radically transform UK home energy efficiency.

Titled, ‘Reinventing Retrofit’,  the Green Alliance make the case that 11 million homes in the UK could benefit from an Energiesprong retrofit, helping cut energy bills and prevent excess winter deaths, currently at their highest level for forty years.

View the report here and below:

Business Support

Enterprises in Devon could apply for 12 hours of free support. To be eligible, enterprises had to be an SME (or community energy group with some economic activity), registered in Devon and looking to engage more with the whole-house retrofit market.

The support on offer was flexible, and included:

  • Technical training courses on energy efficiency, whole-house retrofit and new business models
  • UK based study tours to see other demonstrator projects deliver whole house retrofit
  • Toolbox talks and seminars in Devon, focusing on the ZEBCat demonstrators
  • Support from the ZEBCat supply chain network that will build over time, offering networking and peer-to-peer sharing

Regen worked with the Energy Saving Trust and other key regional partners to deliver the £6.3 million European funded programme, Ready for Retrofit.

Regen took the lead in providing intensive business support to over 600 south west businesses in the construction, energy efficiency and micro-renewable sectors.

September 2011 – September 2015

The vision was to create a sustainable domestic energy efficiency and microgeneration sector in the south west, capable of delivering a massive refurbishment of south west housing stock. This sector would take full advantage from national finance mechanisms up to 2020, such as the Feed in Tariff, Renewable Heat Incentive, Green Deal and the Energy Company Obligation.

The programme resulted in:

  • the creation of more than 203 new jobs, as well as safeguarding a further 77 jobs
  • an increase in local business turnover of £19.8m

The project provided an opportunity to understand and analyse the varied supply chain in the south west. The publications below provide further detail.
