Wind power generation forecast

Wind energy and expected load factor

Here above you will access information on wind energy forecast for the French grid :

  • Reference forecast : generation forecasted available since 6:00 PM for the complete day ahead.
  • Intraday forecast : RTE provides an update for forecasted wind power generation per time unit.

NB : forecasted power data are completed by the forecasted load factor for the French wind energy sector. This index is calculated as a rate between forecasted generation and total wind power installed capacity.

Forecasting methods

RTE establishes wind power generation forecasts on the basis of :

  • The wind energy generated on the grid in the nearing hours,
  • Wind scenarios provided by Meteo France (French weather forecasting service),
  • Technical specifications of the connected wind farms,
  • Wind farms localization.
Forecasted generation depends on geographical zone, wind direction, operational wind mill number...
