Load and load forecasts
Elia monitors the smooth operation of its grid around the clock. This means continuously tracking load and making forecasts.
The chart shows Elia’s current grid load, that can be compared with the forecasted load for today (pink curve), with the measured grid load for the specified reference date (black curve), and with the forecast for the specified forecast date (up to six days ahead) (blue curve).
The Elia-grid load is based on injections of electrical energy into the Elia grid. It incorporates the net generation of the (local) power stations that inject power into the grid at a voltage of at least 30 kV and the balance of imports and exports. Generation facilities that are connected at a voltage of less than 30 kV in the distribution networks are only included if a net injection into the Elia grid is being measured. The energy needed to pump water into the storage tanks of the pump-storage power stations connected to the Elia grid is deducted from the total.
Decentralised generation that injects power at a voltage less than 30 kV into the distribution networks is not included in the Elia-grid load. The significance of this last segment has steadily increased during the last years. The published Elia-grid load forecast is therefore purely informational as large deviations can occur on days with varying output levels of decentralised generation. We are currently working on improving the forecast quality by also taking into account this decentralised generation injecting into the distribution networks.
The Elia-grid comprises networks of at least 30 kV in Belgium plus the Sotel/Twinerg grid in the south of Luxembourg.
