EDNA provides analysis and policy guidance to members and other governments aimed at improving the energy efficiency and demand flexibility of connected devices and networks.
In 2024 EDNA changed its name to reflect an increased focus on ‘demand flexible networked appliances’. These large household appliances can empower consumers and are able to react to requirements from the grid, for example to increase or decrease power consumption in response to renewable energy generation patterns, or to react to local power system constraints.
EDNA will continue its current work on the energy efficiency of data centres, and as required over time, may choose to undertake further work on the energy efficiency of connected devices themselves, as well as other related topics as they arise.

New EDNA report examines the ability of ‘flexibility platforms’ to unlock demand flexibility from appliances in the household and commercial sectors. Download here.
EDNA has published 2 new reports on data centres: Data Centre Energy Efficiency Labels and Public Data on Data Centre Energy Use.
This report describes the Total Energy Model (TEM) 4.0, a novel bottom-up hybrid model designed to forecast data centre energy consumption and evaluate the effect of possible policy interventions on energy use.
This study provides insights into the development of server energy efficiency over the past decade.
This Study conducts a comprehensive and critical review of existing models and assessments of the energy use of data centres.
During its new term (2024 to 2029) EDNA will further increase its focus on demand flexible networked appliances. These appliances, empowering consumers, are able to react to requirements from the grid, for example to increase or decrease power consumption in response to renewable energy generation patterns, or to react to local demand constraints. Having such appliances installed is crucial to a net zero energy grid – their potential to reduce the requirement for expensive energy storage is substantial.
