Understanding UK onshore wind share of electricity generation
The proportion of total domestic electricity generation supplied by terrestrial wind turbine installations across the United Kingdom is tracked by this series. It measures electrical energy output from onshore wind farms as a percentage of overall electricity supplied from all generation sources, distinguishing it from absolute gigawatt-hour volumes and capacity metrics. Micro wind installations are excluded from the main commercial reporting scope, leaving the focus primarily on utility-scale onshore wind farms.
Interpretation requires careful attention to weather seasonality, as wind speeds vary considerably across quarters and influence output independently of installed capacity growth. Early statistical releases are subject to revision as late meter data from network operators are incorporated. Analysts should rely on annual period comparisons rather than adjacent quarters to accurately evaluate structural changes in supply contribution.
Frequently asked questions
- Does this series include offshore wind generation?
- No, offshore installations are reported under a separate dedicated category in the energy statistics table.
- Why do sequential quarter comparisons mislead analysts?
- Pronounced seasonal variations in wind speeds create artificial drops or spikes between adjacent quarters.
- Are small domestic wind turbines counted in this share?
- Small unmetered turbines are generally excluded, with coverage focused on larger grid-connected commercial sites.
