Market signals
Electricity price forecasts and rankings need careful reading.
Electricity Price Watch and Electricity Price Rankings show public market signals. They are useful for timing, comparison and research, but they are not a household bill.
Actual versus forecast
In Electricity Price Watch, an actual point is a value published by the market or source and normalized for display. A forecast point is an estimate for a future interval. When both exist for the same interval, the published actual should take priority.
Forecast confidence matters. A high-confidence forecast can support conservative planning. A low-confidence forecast should be treated as a directional hint, especially when markets are volatile or recent source data is thin.
What the daily ranking measures
Electricity Price Rankings compare average wholesale reference prices for the selected day. Multi-area countries use a simple price-area average. The ranking is useful for comparing public market conditions, but it is not a load-weighted national index and it does not include taxes, network fees or supplier margins.
Why the monthly archive exists
A single day can be noisy. Monthly archives show repeated patterns: which countries were often cheap, where daily spreads were widest and how one country moved through the month. That makes the data more useful for journalists, analysts and homeowners who want context rather than a single headline.
How this connects to home automation
Price data only becomes useful when the home can act. A battery, EV charger, heat pump or air conditioner needs to respect comfort, reserve, solar forecast and user routines. GridPassport treats price as one input in that decision loop.
