This graph gives an annual and monthly overview of wind power generation, both overall and by sub-sector: onshore wind power, offshore wind power.

• The development of wind power production is an important parameter in the energy transition, since it is a renewable and low-carbon energy source. Wind power generation in France began to develop with the construction of onshore wind farms. In 2022, the first offshore wind farm went into service. 
• In 2022, despite relatively unfavourable weather conditions, output rose on the back of expanded capacity. 

The data can be of various kinds:

• Data from RTE meters and distribution network operators. In order to draw up global consumption or production balances, we need to have an aggregated view of all metering data on the transmission and distribution perimeters. These data are only available on the 15th of each month for the month just ended. Although updates are possible for at least 12 months, the consolidated data is very robust from the first date of availability. Provisional data, derived from telemetry set up by network operators at various points on the power grid, supplemented by estimates for non-telemetered production or consumption. Provisional data provide an initial overview, available very quickly after each deadline; they are not of the same quality as metering data (estimates taken into account, less accurate measurement than metering data, etc.). Graph elements based on provisional data are indicated by a specific pictogram on the portal.

This graph gives an annual and monthly overview of the evolution of the wind power capacity (total installed capacity and growth), both overall and by sub-sector: onshore wind power, offshore wind power.

• A key highlight of 2022 was the commissioning, on 23 November 2022, of France's first offshore wind farm off the coast of Saint-Nazaire. This farm comprises 80 fixed-bottom turbines located 12 to 20 km off the coast with a combined capacity of 480MW. 
• Two new offshore wind farms are currently under construction (Saint-Brieuc and Fécamp) and should be operational by the end of 2023.

The graph represents the monthly and yearly capacity factors which correspond to the monthly and yearly average value of the half-hourly capacity factors. It also represents the maximum value of the half-hourly capacity factors.   

• The capacity factor is defined as the ratio between production and installed capacity. 
• In 2022, the weather conditions were not favourable for wind power generation: the wind capacity factor for onshore wind was 21.6%, down from 23.2% en 2021 and 26.6% in 2020. 

The graph represents the yearly and monthly coverage of demand in France, with average and maximum values. 

• The share of demand is calculated for each half-hourly period as the ratio between the wind generation and the gross consumption in France.
