The SAVE Project was an Ofgem funded project run by Scottish and Southern Electricity Networks (SSEN) and partnered by the University of Southampton (UoS), DNV GL and Neighbourhood Economics (NEL).
The innovative programme evaluated the potential for domestic customers to actively participate in improving the resilience of electricity distribution networks and thereby defer the need for traditional reinforcement. The government forecasted an increase in electricity demand of 60% by 2050 meaning peak demand is likely to grow to six times higher than what the network was designed for.
Project Methodology
The SAVE project engaged 8,000 customers across Solent who took part in four distinct engagement methods across three trial windows. Through these trials, SSEN looked to build closer relationships with customers and create a society whereby customers could better control their electricity consumption as well as control or influence the future of their local electricity network. This greater control of peak load brought benefits to both DNOs and customers through monetary means and assumed a wealth of social benefits, such as mitigating the disruption caused by reinforcement works, limiting the most CO₂-intensive forms of consumption, facilitating the adoption of low-carbon technologies and allowing for a priority response to (vulnerable) customers during power outages.
SAVE used a randomised control trial methodology combined with household monitoring and detailed annual surveys to ensure results from its trials were not just scalable and replicable but could be modelled across SSEN’s licence area and the wider UK. The project’s key output was a network investment tool which allowed SSEN engineers to understand the applicability and cost-efficiency of SAVE interventions compared with traditional reinforcement. This tool formed a key part of how Distribution Network Operators (DNOs) could easily and efficiently integrate smart solutions into the build of a smarter grid.

Stakeholder Engagement
Stakeholder engagement was central to the SAVE project, shaping collaboration with partners and suppliers while guiding how trials were delivered, ensuring they ran efficiently, reflected real costs, and focused on maximising benefits for customers and the network.

Modelling network planning
The SAVE project developed a range of models using project data to understand how customers use electricity and respond to interventions, alongside network topology and pricing data to ensure the analysis reflected real network behaviour and commercial realities.
