UKWED Figures explained

RenewableUK's Wind Energy Database (UKWED) is the most definitive database on UK wind energy projects. It contains data about operational onshore and offshore wind projects. We update this database as we receive new information.

Please note that UKWED only holds information on projects of 100kw and larger.

RenewableUK publishes statistics on micro, small and medium wind turbines annually in our "Small and Medium Wind UK Market Report" which can be found here.

Press releases on these reports can be found in our Media Section.

  1. Projects

    657

Projects
The number of operational wind energy projects.

  1. Turbines

    5,645

Turbines
The number of operational wind turbines.

  1. Onshore Capacity (MW)

    7,534

Onshore Capacity (MW)
The total installed capacity of onshore wind farms.

  1. Offshore Capacity (MW)

    3,653

Offshore Capacity (MW)
The total installed capacity of all offshore wind farms.

  1. Energy Produced (MWh)

    27,263,077

Energy Produced (MWh/p.a.)

This is calculated by multiplying the installed capacity in MW by the number of hours in a year (8760) and then multiplying this by DECC’s long-term average capacity factor for (onshore + offshore) wind (27.82%) expressed as a fraction of 1 (e.g. 0.2782). Source for capacity factors is Digest of United Kingdom Energy Statistics (DUKES) published annually by DECC.

 

  1. Homes Powered Equivalent

    6,446,696

Homes Powered Equivalent (p.a.)
This is calculated using the most recent statistics from the Department of Energy and Climate Change showing that annual UK average domestic household consumption is 4,229kWh.

  1. CO2 reductions (pa) in Tonnes

    11,723,123

CO2 Reductions (p.a.) in Tonnes
RenewableUK uses DECC’s carbon saving figure of 430g/kWh. More information. Carbon reduction is calculated by multiplying the installed wind energy capacity in megawatts by the average (onshore + offshore) load factor as a fractional percentage of 1 (e.g. 0.2782), multiplied by the number of hours in the year (8760), multiplied by the number of grammes of CO2 saved per kilowatt hour, divided by 1000 (to align the units, as grammes of CO2 is expressed in kWh). So for a generic 2MW turbine: 2 x 0.2782 x 8760 x 430 / 1,000 = 2,096 tonnes of CO2 per year, assuming an average load factor (onshore + offshore) of 27.82%.
