DFES - LV Headroom (Monitored) Data - New 2024 Dataset
ENW is currently using PreSense units to monitor the power of secondary substations, particularly those with a large number of customers. The data is processed in real-time and aggregated into half-hourly intervals. In its RIIO-ED2 Business Plan, ENWL outlined its plans to achieve 95% network visibility coverage during the price control period using distribution monitoring equipment (PreSense), with the remaining 5% covered by smart meters. As of March 2025, 60% of customers are covered by PreSense.
The substations being monitored have been identified because they have been monitored for over a year, providing sufficient data points throughout the period, especially during winter. This real-time monitoring data is used to identify the maximum demand of secondary substations. There is an ongoing programme to identify new sites for monitoring to expand coverage and improve network visibility.
This dataset contains the headroom (kVA) forecast for PreSense-monitored secondary substations, based on the maximum demand forecast and substation transformer ratings.
The collection of DFES datasets envisages a range of possible views of the future, which indicate how different influences can change electrical demand and generation on our network.
This dataset is an accompaniment to our 2024 DFES report, it contains detailed datasets and interactive tools which allow our customers to understand what our Distribution Future Electricity Scenarios mean to them.
Please refer to our main DFES report for a full description of our forecasts and scenarios. Our forecasts are not precise predictions of what the future is likely to be, but instead frame the uncertainty within our planning as explained in the main report.
While we use reasonable endeavours to ensure that the data contained within this dataset is accurate, we do not accept any responsibility or liability for the accuracy or the completeness of the content held, or for any loss which may arise from reliance on this dataset and/or its related information.
