Introduction: Energy Efficiency is used in other countries to defer the need for capital investment to reinforce the network.

Individual energy efficiency measures or a combination of them have been previously investigated in GB to understand the potential network benefits associated with customers’ behavioural change. However, a holistic approach looking at DNO led energy efficiency as alternative to network reinforcement has not been trialled in GB. If successful, this may lead to significant customer savings.

Objectives: The objective of the project is to identify a method and assess the benefits of a DNO-led rollout of energy efficiency measures by looking at two primary or secondary grid substations which would be considered in phase 2. This will be documented in a report which would summarise the key findings, outline next steps and discuss potential regulatory changes to existing framework. The latter will serve as a basis for discussion with Ofgem.
