- Assumed capacity factors for offshore wind, The Contracts for Difference (Standard Terms) Regulations August 2014, DECC. Generation: 400MW x 0.39 x 8760 x 1,000 = 1,366,560,000KWh / 1,367GWh pa)
- Based on an average annual domestic household electricity consumption of 3,938 (BEIS)
- Every unit (kWh) of electricity produced by the wind displaces a unit of electricity, which would otherwise have been produced by a power station burning fossil fuel. This calculation is made using a static figure of 430g CO2/kWh representing the energy mix in the UK.
