Infographic: Promoting a sustainable energy future

Facts and figures on the UK power mix, environmental programmes and offshore transmission.

What generates Britain's power?

UK electricity supply mix 2019 (%):

• Coal-fired power stations 2.3% (6.49 TWh)
• Gas-fired turbines 41.9% (116.57 TWh)
• Renewable sources 29.4% (81.69 TWh)
• Nuclear plant 18.4% (51.03 TWh)
• Other sources 0.4% (1.01TWh)
• Interconnectors 7.6% (21.17 TWh)

Reducing the UK’s carbon emissions and increasing the energy we get from sources consumers’ interests at our core, we run a range of government consumer and like renewables, will help to ensure the security and sustainability of our energy supplies for generations to come. With the protection of future and existing environmental programmes and manage the regulatory regime for offshore electricity transmission networks

Environmental programmes

£8.75 Billion: the value of environmental schemes we've administered during 2018/19.

Helping people in difficult situations

£2.79 Billion: amount of support to fuel poor households through the Warm Home Discount since its launch in 2011 to March 2020.

£348 Million: how much suppliers paid in support to people who needed it in 2019/20.

The UK government announced that the WHD scheme will continue to support fuel poor customers until 2020/21 at the 2015/16 level of support of £320 million a year, rising with inflation.

Promoting energy efficiency and renewable electricity

2,883,639: the number of efficiency measures installed under the Energy Company Obligation across over 2.1 million households to January 2021.

114,812,243: Certificates (ROCs) issued for eligible renewable electricity generated under the Renewables Obligation in 2019/20.

859,889: The number of solar panel installations registered for the Feed-in Tariff to January 2021.

Generating heat through more renewable sources

Domestic Renewable Heat Incentive

84,707: Number of renewable heat installations accredited to January 2021.

Non-Domestic Renewable Heat Incentive

5.26 GW: The total installed capacity to January 2021.

Offshore transmission

£5 Billion: Investment value in 6.9GW of offshore transmission projects under our competitive tender process (Tender Rounds 1-5).

£700 Million: Estimated savings for consumers resulting from our competitive tender process to connect offshore wind farms to the GB high voltage grid. (CEPA and BDO evaluation Review based on Net Present Value figures at 2014/15 price levels)
