Project REMeDY

Focusing on Southend-on-Sea, REMeDY (spearheading a Revolution in Energy Market Design) has developed an innovative smart local energy system model for decarbonising energy use across heat, transport and electricity.

About the project

The model is based around a smart heat network combined with a private wire electricity network linking renewables generation and battery storage.

The REMeDY model optimises energy production, storage and use and has been shown to be a viable low-carbon energy solution for new domestic and commercial developments.

The model responds to the needs of stakeholders across a building’s lifecycle including developers, social housing providers, owners and tenants. It is informed by a detailed review of the energy needs and opportunities in and around Southend-on-Sea.

REMeDY has also created a project pipeline, exploring the potential to deploy the model in new build and retrofit real-world developments.

What did the project achieve?

  • A smart local energy system model capable of supporting decarbonisation across heat, electricity and transport that is regulatorily compliant and commercially investable.
  • Eight REMeDY solutions explored for real-world housing/commercial building developments with one currently being taken forward with project developers.
  • Detailed insights into the Southend-on-Sea energy system through an energy and carbon review.
  • Extensive engagement with local citizens through a range of innovative approaches including community ECO days and a net zero superhero programme engaging residents over 10 weeks.

Key lessons learnt

  1. Low-carbon smart energy systems based on heat networks can offer a competitive alternative to heat pumps.
  2. The incentives on building developers are not aligned with the adoption or development of smart energy networks.
  3. REMeDY has the potential to offer a lower-cost pathway compared with other zero-carbon options for many existing buildings, particularly for buildings with low energy efficiency. But mechanisms are needed to recover costs over longer timescales.

Next steps

  • REMeDY solutions being taken forward in one newbuild mixed domestic and commercial development.
  • Southend-on-Sea City Council will look for opportunities to reflect the learning from the project and the potential for REMeDY solutions within the net zero energy strategy currently being developed.
