SSEN NeRDA (Near Real-time Data Access) API
Near real-time power flow data from SSEN Distribution's EHV, HV and LV networks, drawn from SCADA PowerOn, LV monitoring equipment, the load model forecasting tool, the connectivity model and the Long Term Development Statement. The documented endpoints are a static substation endpoint per licence area (nerdastatic-SEPD, nerdastatic-SHEPD) and time-series endpoints (nerdart_after, nerdart_between) queried by nerda_measurement_id and ISO 8601 timestamps. Access requires a free SSEN account, acceptance of the portal terms and conditions, and an API key generated in the portal API console; anonymous calls to the documented endpoints return 404.
