Our Distributed Future Energy Scenarios Network Scenario Headroom Report (DFES NSHR) is part of our Network Development Plan (NDP). The April 2024 DFES NSHR dataset uses our 2023 network, loading and scenario data, with the Long Term Development Statement November 2023 as baseline. For further information on the NDP and the methodology to produce the DFES NSHR dataset please see Long Term Development Statement and Network Development Plan Landing Page The DFES NSHR indicates the amount of unused network capacity for demand and generation over time to 2050 on our Bulk Supply Point and Primary substations. It shows where we may need to further reinforce our substations or procure flexibility services beyond our existing plans, if the energy system develops as indicated in each of our scenarios. Since the report indicates unused substation capacity in each year, please note unused capacity may be contractually committed to customers. Those seeking connection should contact our connections gateway to understand the latest view of available capacity. The headroom tables show firm capacity - more capacity may be available for customers on a non-firm, flexible or curtailable connection. The demand headroom tables reflect our latest firm capacity figures for demand, consistent with the May 2024 LTDS. As noted in the methodology, unused substation capacity (headroom) is indicative and may be already contractually-committed to specific customers. Methodological approach Forecasting: The process begins with forecasting future network loads and demands. This often involves scenario planning to predict how energy consumption and generation will evolve over the next 5 to 10 years. Data Collection: Gathering data from various sources, including historical usage patterns, projected growth in renewable energy, and changes in regulatory frameworks. Analysis of Network Capacity: Assessing the current capacity of the network to identify areas where reinforcement or upgrades are necessary. This includes evaluating substations and distribution lines. Option Development: Creating potential solutions to address identified constraints. This may involve traditional reinforcement methods or exploring flexibility services that can alleviate pressure on the network. Stakeholder Engagement: Consulting with stakeholders, including local authorities, developers, and energy providers, to gather input and ensure the plans align with community needs and regulatory requirements. Reporting: Compiling findings into a structured report that outlines the methodology, assumptions, and planned interventions. This report is typically made available to the public for transparency. Review and Update: The methodology is reviewed periodically to incorporate new data, stakeholder feedback, and changes in energy policy or technology. Quality Control Statement Quality Control Measures include: Verification steps to match features only with confirmed functional locations. Manual review and correction of data inconsistencies. Use of additional verification steps to ensure accuracy in the methodology. Assurance Statement The Open Data Team and Network Insights Team worked together to ensure data accuracy and consistency.
