This registry provides comprehensive search capabilities across all Capacity Market components:
The search is intelligent and will try to determine what you're looking for based on your query.
You can combine search terms to narrow results, such as "London Battery" to find battery storage in London.
Searches are not case-sensitive, and partial matches are supported (e.g., "Manch" will find "Manchester").
The Capacity Market runs regular auctions where providers compete to secure agreements. There are two main types:
Each auction results in agreements that specify how much capacity providers must deliver and the payment they'll receive.
Auction years are displayed as badges (e.g., 2023-24) that you can click to view details for that specific auction year.
The Capacity Market ensures the UK has sufficient electricity supply during periods of high demand or system stress.
Providers receive payments for ensuring their capacity is available, creating a more stable and resilient electricity market.
Search results are grouped by location and show important details about each component:
Each result shows the component's capacity, location details, and participation in specific auction years.
You can sort results by relevance, location, or date using the sort options.
Pagination controls appear at the bottom when there are multiple pages of results.
Components at the same location with the same description are grouped together to reduce duplication.
Each group shows:
Grouping helps identify multi-year contracts and related components at the same site.
The total capacity shown combines all components in the group.
Components can be expanded to show individual details by clicking the expand icon.
You can sort search results by:
Click the column headers to change sort order.
You can filter results using the search refinements at the top of the results page:
We provide two map-based tools for exploring capacity market data:
The Map Explorer is our advanced interactive mapping tool, specifically designed for comprehensive data exploration with:
The Search Map View combines search functionality with map visualization, offering:
Both tools provide a visual representation of capacity distribution across the UK, but serve different exploration needs.
Use the map controls to zoom in on specific regions or areas of interest. The map automatically adjusts clustering based on your zoom level to provide the clearest view of capacity distribution.
We're here to help with any questions about the Capacity Market Registry.
