Every piece of data on áramfigyelő comes from a publicly available, official source. This page lists, per source, what it provides, how often it updates, and any licence/attribution requirement that applies.
Domestic grid load (actual and forecast), generation mix by fuel type, and cross-border flows — from MAVIR's own public real-time dashboard (RTDW). MAVIR data is indicative, not an official certified figure.
Grid load, generation by plant type and unit, and cross-border physical flows with neighbouring countries (Slovakia, Austria, Croatia, Romania, Serbia, Ukraine, Slovenia) — from European transmission system operators' shared, official transparency platform.
The day-ahead exchange price is sourced from energy-charts.info, original data provider Bundesnetzagentur | SMARD.de, under a CC BY 4.0 licence. Data is used unmodified.
Grid frequency is sourced from energy-charts.info, original data provider Fraunhofer ISE (Freiburg), under a CC BY 4.0 licence. The displayed value is the last sample taken every 15 minutes from the source's 1-second-resolution series.
EUR/HUF reference exchange rate, from the ECB's official daily (business-day) publication. On weekends and holidays the most recent available business-day rate is shown, not a fabricated daily value.
Danube water level and temperature at Paks, from OVF's public gauge listing. The water level forecast (also OVF's official forecast, looking roughly 6 days ahead) comes through a separate source — when that source is unreachable (as it was for days in August 2026, due to a broken TLS certificate chain on OVF's own site), the forecast widget stays empty with a "no data" notice.
Environmental dose-rate readings (nSv/h) from monitoring stations around the Paks plant, from HAEA's official public environmental radiation monitoring system. This is the regulator's own measurement, not our estimate.
Live, per-block output for all four units comes directly from the plant operator's own public website, atomeromu.hu.
Precipitation data across the Danube basin, from Open-Meteo's open, free weather API.
The base map data comes from the Natural Earth public-domain dataset.
An automated process queries every source listed above every 15 minutes and saves the result into one unified snapshot. If a source does not respond in a given cycle, that reading is shown as missing, not zero — see the About page for the full explanation of this principle.
