Network Development Plan

The Network Development Plan (NDP) is part of a new Electricity Distribution Licence Condition (SLC25B), which requires all Distribution Network Operators to publish before 1st May 2022. The Network Development Plan outlines how National Grid Electricity Distribution (NGED) expect to develop our network over a five to ten year period. The NDP forms part of the NGED investment planning process, as outlined below.

The strategic planning process uses the Distribution Future Energy Scenarios (DFES) as an input to project how we expect customers to use the distribution network as the UK transitions to a net zero future. The network impact assessment is covered by the Network Development Plan, which aims to identify where and when investment is expected to accommodate our forecast growth. Any constraints identified are evaluated using the Distribution Network Options Assessment (DNOA), which outlines the optimal investment pathway to take.
