A key output from the Solent Achieving Value from Efficiency (SAVE) project mentioned on demand models for infrastructure resilience was the Network Investment Tool: a suite of models to improve the simulation of low-voltage distribution networks, thus better informing future investment strategies.

Trial aim: to test a number of behavioural interventions aimed at reducing electricity demand during the network peak hours (4 to 8pm).

Design: a large-scale randomised controlled trial (4,000 households).

Methods: Data-informed messaging (postal & online), financial rewards, banded pricing (peak-hours rebate), energy efficient lighting upgrades.

Data: electricity demand, socio-demographic, appliances, time-use diaries.
