The energy produced in MegaWatt hours per year (MWh/p.a.) is calculated by multiplying the installed capacity of the wind farm in megawatts (MW) by the number of hours in a year (8,760) and then multiplying this by the locally independently assessed capacity or load factor (around 30.0 per cent) expressed as a fraction of 1 (e.g. 0.3). At Banks Renewables, we use the local, independently assessed, capacity or load factor in calculating the performance of our wind farms wherever possible. For example: the energy produced each year by one typical modern onshore wind turbine with an installed capacity of 3.4 MW x 8760 x 0.3 = 8,935 MWh/p.a.
So an onshore wind farm with six 3.4 MW turbines would generate six times this much electricity each year.
6 x 8,935 = 53,611 MWh/p.a.
The average domestic household consumption in the UK (as of December 2020) is around 3,578 kWh per year. For example, the equivalent number of homes that can be powered by a single 3.4 MW wind turbine is calculated by dividing the electricity generated each year (as calculated above) by the average annual domestic household electricity consumption as follows:
8,935 MWh/p.a. divided by 3.578 MWh = 2,497 households
Carbon reduction is calculated by multiplying the total amount of renewable zero carbon electricity generated by the wind farm each year by the number of tonnes of carbon which would have been produced to generate the same amount of electricity using the current year’s UK Grid GHG emission factor which includes electricity generated using fossil fuels (gas, coal and oil), nuclear and renewables. Between 2011 and 2020 Banks onshore wind farms had displaced 621,787 tonnes of CO2e from the UKs electricity supply grid.
In 2019, businesses active in the UK low carbon and renewable energy economy (LCREE) generated £42.6 billion in turnover and employed 202,100 employees (FTE). Banks Renewables connect2Renewables initiative encourages local companies to join our supply chain for goods and services needed to construct and operate our onshore wind, solar and energy storage projects adding value and opportunity to the local economy in the communities that host our renewables developments.
At Banks Renewables, we have led the way in community engagement around the design, construction and operations of our wind farms. We firmly believe the success of our business depends upon building strong relationships with the communities around our developments and delivering local social, economic and environmental benefits. We call this development with care. It is at the heart of all we do. Each project is developed hand-in-hand with the local community so each is bespoke to that area. Each of our wind farms has a community fund that has been established to provide financial assistance to community groups, voluntary organisations and the local community and to support projects that improve the environment and help to tackle climate change. Some of our funds are able to provide support for local training and employment initiatives. The geographical boundaries for fund eligibility will normally be restricted to the community councils or parishes closest to the wind farm. Projects outside of these areas may also be eligible if it can be shown that they benefit local people from these areas. Please see our Wind Farms Community Funds page for more information.
