Energy Monitoring

What we monitor

Day-ahead electricity prices for the Estonian market, sourced from Elering (Estonian TSO) and Nord Pool spot market.

Data source

• Elering API / Nord Pool — official market data
• Collection frequency: hourly
• Collector: energy_collector.py

What we measure

• Average price (€/MWh) — mean across all hourly slots for the day
• Maximum price — peak hour
• Minimum price — cheapest hour
• Price anomaly — when the current day’s average exceeds the 7-day rolling average by more than 2.5 standard deviations

Why it matters

Energy price spikes can indicate supply disruptions (pipeline issues, interconnector outages), geopolitical pressure (gas supply manipulation), or infrastructure problems. The Baltic energy market is partially dependent on cross-border flows that can be disrupted.

Limitations

• Covers Estonian market only — Finnish, Latvian, Lithuanian prices may differ
• Day-ahead prices don’t capture intraday volatility
• Price spikes have many causes (weather, demand, maintenance) — not all are security-relevant
