Heatmap Data - Demand

Our Demand Heatmap Data provides the most updated substation by substation information related to demand connections to our Extra High Voltage (EHV) and High Voltage (HV) network. Data such as firm capacity, max and min demands, existing and contracted demand, various fault level information, and known constraints are included to produce an indicative headroom value. These are then turned into a red, amber and green status based on headroom and possible constraints. The bounds for these RAG status can be seen below.If you are unsure of any of the column meanings, please hover over the column heading for a description.Related Feature PagesEmbedded Capacity Register Page - Our Embedded Capacity Register provides information on generation and storage sites, both connected to and accepted to connect to our network.Network Availability Heat Maps - Our Heat Maps provide a high level overview of network availability at Primary, Bulk Supply and Grid Supply Point level using a traffic light systemRegional Demand and Generation Tracker - Our Regional Demand and Generation Tracker provides near real time data for the generation mix of our network over the last 30 days.Glossary of TermsOur Glossary dataset provides definitions for various terms and acronyms found throughout our data.
