Elexon Insights Solution API

The Elexon Insights Solution API is a publicly accessible REST API providing free access to UK electricity balancing and settlement data. The API requires no authentication or API key and serves production-grade data continuously. Endpoints are grouped into Dataset Endpoints (raw published data, including superseded historical records), Opinionated Endpoints (specific use-case queries such as demand evolution or generation availability), Streaming Endpoints (JSON only, no paging restrictions), and Summary/Reference Data endpoints. Response formats include JSON, XML, and CSV. Core data domains include balancing mechanism dynamic and physical data per BMU, bid-offer data and acceptances, disaggregated and net balancing services adjustments (DISBSAD/NETBSAD), physical notifications (PN/QPN), non-BM STOR (NONBM), and 50+ BMRS datasets covering generation, demand, frequency, temperature, and market transparency. An interactive OpenAPI specification is published at https://data.elexon.co.uk/swagger/v1/swagger.json.
