EVALUATION

AN INDEPENDENT EVALUATION OF THE LCNF
D.9 Network Configuration
Low Energy Automated Networks (LEAN)
Project Title
Low Energy Automated Networks (LEAN)
Tier 2
DNO
Southern Electric Power Distribution plc. (SEPD)
Status
New
LCNF project funding £2,670k
Project objectives LEAN seeks to demonstrate new methods that can be applied to existing assets to reduce losses in the shorter term. The
principal method for the LEAN project involves the use of a Transformer Auto Stop Start mechanism. SEPD will deploy a second
method, Alternative Network Topology, where appropriate. LEAN builds on learning captured from SEPD’s previous LCNF Tier 1
and IFI projects.

Overview of assessment, sources of evidence and comments
Assessment:
The project clearly facilitates a reduction in losses.
The carbon benefits are credible and quantified.
Evidence:
LEAN will directly reduce electrical losses and associated carbon emissions. If the LEAN solution is proven,
it will help DNOs to manage the effects that distributed generation connection and other low carbon
technologies will have on the network.
Early analysis extrapolated across GB indicates that the methods will deliver a reduction in annual network
losses of up to 31,838MWh, which is equivalent to 6,421 tonnes of CO 2 .

Assessment:
The project could deliver a modest financial benefit at primary substation sites.
Evidence:
The financial benefit will be based on the saving associated with the cost of losses.
