Hartlepool nuclear power station is a nuclear power station situated on the northern bank of the mouth of the River Tees, 2.5 mi south of Hartlepool in County Durham, North East England. The station has a net electrical output of 1,185 megawatts, which is 2% of Great Britain's peak electricity demand of 60 GW. Electricity is produced through the use of two advanced gas-cooled reactors (AGR). Hartlepool was only the third nuclear power station in the United Kingdom to use AGR technology. It was also the first nuclear power station to be built close to a major urban area.
The Ferrybridge power stations were a series of three coal-fired power stations on the River Aire near Ferrybridge in West Yorkshire, England, in operation from 1927 to 2016 on a site next to the junction of the M62 and A1(M) motorways.
Ballylumford power station "C" station is a natural-gas-fired power station in County Antrim, Northern Ireland, UK. With its main plant generating 600 megawatts of electricity, it is Northern Ireland's largest power station and provides half its power. Overall the station produces 600 MW. The plant is located at the tip of the Islandmagee peninsula, which separates Larne Lough from the Irish Sea. The lough is a Site of Special Scientific Interest. The 3 chimneys of the now decommissioned "B" station are 126 metres tall. East of the station is the Ballycronan More converter station, the Northern Ireland end of the Moyle Interconnector, a subsea HVDC interconnector connecting the NI electricity system to Great Britain.
Energy in the United Kingdom came mostly from fossil fuels in 2021. Total energy consumption in the United Kingdom was 142.0 million tonnes of oil equivalent in 2019. In 2014, the UK had an energy consumption per capita of 2.78 tonnes of oil equivalent compared to a world average of 1.92 tonnes of oil equivalent. Demand for electricity in 2014 was 34.42 GW on average coming from a total electricity generation of 335.0 TWh.
Aberthaw Power Station refers to two decommissioned coal-fired and co-fired biomass power stations on the coast of South Wales, near Barry in the Vale of Glamorgan. They were located at Limpert Bay, near the villages of Gileston and West Aberthaw. The most recent power station on the site, Aberthaw B Power Station, co-fired biomass and as of 2008 had a generating capacity of 1,560 megawatts (MW). The power station closed on 31 March 2020.
Baglan Bay power station is a disused 525MWe gas-fired power station situated on Baglan Moors just west of Port Talbot in Wales.
Drax Group PLC is a power generation business. The principal downstream enterprises are based in the UK and include Drax Power Limited, which runs the biomass fuelled Drax power station, near Selby in North Yorkshire. The Group also runs an international biomass supply chain business. The company is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.
Eggborough power station was a coal-fired power station in North Yorkshire, England, which was capable of co-firing biomass. It was situated on the River Aire, between the towns of Knottingley and Snaith, deriving its name from the nearby village of Eggborough. The station had a generating capacity of 1,960 megawatts, enough electricity to power 2 million homes, equivalent to the area of Leeds and Sheffield.
Renewable energy in the United Kingdom contributes to production for electricity, heat, and transport.
Kilroot power station is a fossil fuel power plant on the north shore of Belfast Lough at Kilroot near Carrickfergus in County Antrim, Northern Ireland. The plant currently has a 141 megawatt (MW) capacity from four standby Gas Turbines and a 10 MW battery energy storage capacity from the Kilroot Advancion Energy Storage Array.
Sutton Bridge Power Station is an 819 MW gas-fired power station in Sutton Bridge in the south-east of Lincolnshire in South Holland, England. It is situated on Centenary Way close to the River Nene. It is a major landmark on the Lincolnshire and Norfolk border and on clear days with its bright red lights it can be easily seen as far away as Hunstanton.
Staythorpe C Power Station is a 1,735 MWe gas-fired power station at Staythorpe between Southwell and Newark-on-Trent in Nottinghamshire, England, between the River Trent and Nottingham to Lincoln railway line. The station was handed over to the owner RWE from Alstom Power with full commercial operation being achieved in December 2010. The official opening ceremony attended by Charles Hendry, Minister of State took place on 9 May 2011.
Pembroke B Power Station is a 2,200 MWe natural gas-fired power station near Pembroke in Wales. The power station was officially opened in September 2012 and is the largest gas-fired power station in Europe. It is also the largest power station to be built in the UK since Drax power station came online in 1986. Pembroke Power Station currently generates enough power to supply 3.5 million homes and businesses. It is operated by RWE.
The Tilbury power stations were two thermal power stations on the north bank of the River Thames at Tilbury in Essex. The 360 MW dual coal- and oil-fired Tilbury A Power Station operated from 1956 until 1981 when it was mothballed, prior to demolition in 1999. The 1,428 MW Tilbury B Power Station operated between 1968 and 2013 and was fueled by coal, as well as co-firing with oil and, from 2011, biomass. Tilbury B was demolished in 2016–19. Since 2013 three other power stations have been proposed or constructed in Tilbury.
The Uskmouth power stations refers to a series of two coal-fired power stations at the mouth of the River Usk in the south-east of Newport, Wales. The first of the two station, Uskmouth A power station, was built in the 1940s and demolished in 2002.
The United Kingdom has a National Grid that covers most of mainland Great Britain and several of the surrounding islands, as well as some connectivity to other countries. The electrical sector supplies power at 50 Hz AC, and ~240 volts is supplied to consumers. In 2020 the electricity sector's grid supply came from 55% low-carbon power, 36.1% fossil fuelled power, and 8.4% imports. Renewable power is showing strong growth, while fossil fuel generator use in general and coal use in particular is shrinking, with historically dominant coal generators now mainly being run in winter due to pollution and costs, and contributed just 1.6% of the supply in 2020.
