Live frequency, congestion, and weekly summaries for anyone who wants to understand the European grid — built on Fraunhofer ISE and TSO data.
Real-time Continental European grid frequency. The nominal frequency is 50.000 Hz — deviations indicate supply-demand imbalance.
Grid frequency is the heartbeat of the European power system. At exactly 50.000 Hz, supply matches demand. When a power plant trips or 3 GW of offshore wind drops in an hour, frequency tells you first — before market prices, before TSO alerts, before the news.
We combine Fraunhofer ISE frequency data, ENTSO-E generation/load context, TSO balancing activation from Netztransparenz and Elia, and Open-Meteo weather — then use statistical algorithms and Quasar AI to explain not just what happened, but why.
Free, always. 1-second frequency data with SOGL-aligned stress thresholds. See grid events as they happen — not hours later in a TSO report.
Every Monday: the week's key stats, stress events ranked by severity, and an AI-generated operational outlook. KPIs at a glance, no registration required.
The full picture. 12-page PDF with frequency distribution, event root causes, weather/generation correlation, and battery dispatch windows. Free in the public archive — explore the sample today.

View Free Weekly SummaryThe free summary gives you the headlines. Grid Pulse is the full weekly briefing: every stress event traced to wind drop-offs, generation trips, or cross-border imbalances, statistical distributions that show whether the grid is tightening, and a 7-day outlook of expected frequency conditions.
Built for battery operators sizing arbitrage windows, traders watching balancing markets, grid engineers tracking FCR activation, and analysts who need evidence-backed frequency intelligence — not raw data dumps.
