E.ON UK is a British energy company and part of the global energy firm E.ON (which is headquartered in Essen, Germany and has around 43,000 employees worldwide). It is the second largest electricity and gas supplier in the UK and is sometimes referred to as one of the so-called "Big Six". It was founded in 1989 as Powergen, and was listed on the London Stock Exchange and was once a constituent of the FTSE 100 Index. It has been a subsidiary of E.ON since 1 July 2002.[3]

E.ON, was formerly a vertically integrated utility company with interests in electrical generation, electricity distribution in the Midlands region, and in the electricity and gas supply markets. It took a pioneering role in the development of large scale renewables including the construction and operation of the UK's first offshore wind farm at Blyth in Northumberland.[4] It became one of the first in the world, and the first major UK energy company, to significantly[5] alter its structure by spinning off its fossil generation business so it could focus on energy supply, grid development and renewables.

On 10 March 2018 it was announced E.ON would acquire[6] Innogy in €43bn deal with RWE.

Powergen was formed in 1989 as a Public Limited Company which was wholly owned by the UK government and acquired about 50% of the Central Electricity Generating Board generating capacity. Sir Robert Malpas was Chairman of the Group from 1989 to 1991.[7] Sixty per cent of Powergen was sold to private investors in 1991, followed by the remaining 40% in March 1995.[8] It expanded considerably by acquiring the regional electricity company East Midlands Electricity in 1998[9] and the supply business of TXU Energi in 2002.[10] Powergen was eventually taken over itself by E.ON, an acquisition which was completed in January 2002.[11]

It then bought the distribution network operator Midlands Electricity in 2004.[12] This was merged with the distribution business of East Midlands Electricity and rebranded as Central Networks.[13] The Industrial & Commercial Retail business was rebranded as E.ON UK on 5 July 2004.[14] The creation of the Central Networks business in April 2004 included "a company of E.ON" as part of its logotype. In October 2005 it was also added to the Powergen logotype.

In June 2007, a major advertising campaign entitled "The wind of change", containing advertisements using the E.ON logo, was launched. The campaign featured the Robin Rigg offshore wind farm in the Solway Firth, currently in development. In the consumer market, this was complemented by a replacement of the mostly blue Powergen identity to the red identity of E.ON, and the launch of a new product, Go Green, using electricity from renewable sources and carbon offset gas.

On 22 October 2007, the company announced that the E.ON Energy and Powergen brands would change to E.ON as of 1 November and 3 December 2007 respectively.[15]

In January 2008, E.ON acquired West Midlands-based CHN Group, a provider of heating services to builders, local authorities and housing associations across the region.[16] and in August 2008 completed the purchase of the Street Lighting business lighting projects of ABB Ltd. It intended to improve its existing lighting business by purchasing the ABB business.ABB.[17]

In 2008 and 2009 a number of protests took place at E.ON UK's power station including a Climate Camp at their Kingsnorth power station in August 2008[18] and at their Ratcliffe-on-Soar Power Station in October 2009.


On 20 January 2010, E.ON UK announced the closure of its Rayleigh Customer Service Centre and the loss of 600 jobs.[19] The company was forced to bring forward the announcement by one day after the information was leaked to a local newspaper. This has been criticised as a money-saving exercise by an organisation which has seen an increase in profits of 18% in 2009[20] and news that E.ON UK have made £80 million in profits so far in the financial year 2009/10. Other businesses within E.ON were also affected by these round of job losses, including its IT support and its Highways Lighting operations.

In March 2011, E.ON sold Central Networks to PPL's UK subsidiary Western Power Distribution for £3.5 billion.[21]

In October 2012, E.ON sold its 50% stake in Horizon Nuclear Power to Hitachi for £348 million. The other 50% stake, held by RWE npower, was also sold to Hitachi for the same amount, giving a total sale value of £696 million.[22]

Late in 2012, E.ON UK announced the closure of the 'Ignite' business, originally tasked with bringing alternative localised-generation products to market for E.ON UK.

In 2013, E.ON Home Energy Services was sold in a management buyout.[23]

Acquisition of Npower

Just after the failed SSE-Npower merger of retail assets in late 2018,[24] it was reported that the Big Six energy suppliers would still consolidate to the Big Five, as Npower would be acquired by default by E.on UK, due to the already-planned asset swap of the respective German parents innogy and E.ON. [25]


The company's headquarters are in Coventry at Westwood Business Park, in a building designed by Bennetts Associates. There are numerous other offices and power generation sites across the country.

UK businesses

E.ON UK's businesses consist of:

  • Energy Solutions (a merger of the former Retail and Energy Services businesses)
  • Business Services (an internal service provider)
  • Central functions including Corporate Affairs & Finance under the banner UK Centre
  • E.ON Climate and Renewables - renewables and climate protection projects
  • E.ON IT UK - the company's IT service provider


E.ON operates a number of onshore and offshore wind farms, biomass power stations, Combined Heat and Power plants in the UK.[26] It formerly ran[27] a number of fossil plants which are now wholly owned and run by Uniper.


ITV National Weather

Powergen/E.ON sponsored the ITV National Weather forecasts from its launch on 13 February 1989 until 31 December 2007, a period of 18 years. They were known for their memorable sponsorship sequences from a set introduced on 5 April 1993 which featured weather themes circulating around (or parts of) the Powergen logo, and from 4 November 1996, the Weathergens, a "mascot" of Powergen representing different types of weather. After several different sets of idents throughout the 2000s, Powergen eventually became E.ON in 2007 and the sponsorship was changed to accommodate the name change. The sponsorship ended on 31 December 2007 and from 4 July 2016 to 8 July 2018, ITV National Weather is formerly sponsored by rival energy company SSE on all ITV plc stations and UTV.


In 2006, E.ON UK announced that it was to be the sponsor of the FA Cup for a four-year period. During this period, the competition is formally called "The FA Cup sponsored by E.ON". Before 2006, the company had sponsored the rugby union and rugby league cup competitions under the Powergen brand. The original four-year deal was extended to a fifth year as The FA failed to secure a new sponsor. The announcement was unpopular as it was made in the same week as the confirmation of closure of the Rayleigh Call Centre.

The company was the energy partner of the Football League, and sponsors the E.ON Lounge at the Ricoh Arena, the home of Coventry City F.C. Football Club.

In other sports, E.ON UK sponsored the Tour of Britain cycling championship from 2007 to 2009, and in 2007 launched a campaign with Ellen MacArthur to encourage energy efficiency within businesses.

Distribution network operators

E.ON UK is an energy supplier for homes across the country. They do not however manage the network of towers and cables that distributes electricity - these are maintained by distribution network operators (DNOs) which vary from region to region. If, for instance, there is a power outage it is necessary to contact the appropriate DNO rather than the energy supplier. See entry on distribution network operator for a full list.[28]

Kingsnorth was a dual-fired coal and oil power station on the Hoo Peninsula at Medway in Kent, South East England. The four-unit station was operated by energy firm E.ON UK, and had a generating capacity of 2000 megawatts. It was capable of operating on either coal or oil though in practice oil was used only as a secondary fuel or for startup. It was also capable of co-firing biofuel, up to a maximum of 10% of the station's fuel mix. A replacement power station, also coal-fired, was considered by owners E.ON, but plans were abandoned. The proposed replacement attracted substantial public protests and criticism, including the 2008 Camp for Climate Action.

List of onshore wind farms in the United Kingdom

This is a comprehensive list of onshore wind farms (more than 1 turbine) in the UK. This information is gathered from multiple Internet sources, primarily the UK Wind Energy Database from RenewableUK (formerly BWEA) and The Wind Power's database, and is current up to October 2010. The name of the wind farm is the name used by the energy company when referring to the farm and is usually related to the name of the physical location. E.g. hill, moor, fell, down etc. or the name of the agricultural farm for the smaller installations on property owned by farmers. The "wind farm" part is implied and hence removed for clarity in most cases.

List of power stations in Scotland

This list of power stations in Scotland includes current and former electricity-generating power stations in Scotland, sorted by type. Scotland is a net exporter of electricity and has a generating capacity of over 10GW. Much of this is generated by conventional fossil fuel-burning power stations, as well as two large nuclear power stations. Several hydro-electric schemes operate in the Highlands. Scotland also has an increasing number of wind farms, due to the large proportion of upland areas. As of July 2010, there were 100 operating wind farms in Scotland with a combined capacity of 2.1GW; and a further 96 projects under construction or consented, with capacity of 3.0GW. A number of other power plants include an experimental wave power generator on Islay, and Steven's Croft near Lockerbie, the UK's largest wood-fired biomass power station. Since 2016 no coal fired power stations are operating in Scotland.

London Array

The London Array is a 175 turbine 630 MW Round 2 offshore wind farm located 20 km off the Kent coast in the outer Thames Estuary in the United Kingdom. It is the second largest offshore wind farm on Earth, after the Walney Extension.

Construction of phase 1 of the wind farm began in March 2011 and was completed by mid 2013, being formally inaugurated by the Prime Minister, David Cameron on 4 July 2013.

The second phase of the project was refused planning consent in 2014 due to concerns over the impact on sea birds.


Nottingham ( (listen) NOT-ing-əm) is a city and unitary authority area in Nottinghamshire, England, 128 miles (206 km) north of London, 45 miles (72 km) northeast of Birmingham and 56 miles (90 km) southeast of Manchester, in the East Midlands.

Nottingham has links to the legend of Robin Hood and to the lace-making, bicycle (notably Raleigh bikes), and tobacco industries. It was granted its city charter in 1897 as part of Queen Victoria's Diamond Jubilee celebrations. Nottingham is a tourist destination; in 2011, visitors spent over £1.5 billion—the thirteenth-highest amount in England's 111 statistical territories.In 2017, Nottingham had an estimated population of 329,200. The population of the city proper, compared to its regional counterparts, has been attributed to its historical and tightly-drawn city boundaries. The wider conurbation, which includes many of the city's suburbs, has a population of 768,638. It is the largest urban area in the East Midlands and the second-largest in The Midlands. Its Functional Urban Area, also the largest in the East Midlands, has a population of 912,482. The population of the Nottingham/Derby metropolitan area is estimated to be 1,610,000. Its metropolitan economy is the seventh largest in the United Kingdom with a GDP of $50.9bn (2014). The city was the first in the East Midlands to be ranked as a sufficiency-level world city by the Globalization and World Cities Research Network.Nottingham has an award-winning public transport system, including the largest publicly owned bus network in England and is also served by Nottingham railway station and the modern Nottingham Express Transit tram system. To the west lies Derby, separated from it by the M1 motorway that cuts through.

It is also a major sporting centre, and in October 2015, was named 'Home of English Sport'. The National Ice Centre, Holme Pierrepont National Watersports Centre, and Trent Bridge international cricket ground are all based in or around the city, which is also the home of two professional football teams; the former world's oldest professional league club Notts County, and Nottingham Forest, famously two-time winners of the UEFA European Cup under Brian Clough and Peter Taylor in 1979 and 1980. The city also has professional rugby, ice hockey and cricket teams, and the Aegon Nottingham Open, an international tennis tournament on the ATP and WTA tours. This accolade came just over a year after Nottingham was named as the UK's first City of Football.On 11 December 2015, Nottingham was named a "City of Literature" by UNESCO, joining Dublin, Edinburgh, Melbourne and Prague as one of only a handful in the world. The title reflects Nottingham's literary heritage, with Lord Byron, D. H. Lawrence and Alan Sillitoe having links to the city, as well as a contemporary literary community, a publishing industry and a poetry scene.The city is home to two universities - Nottingham Trent University and the University of Nottingham and also hosts a campus of the University of Law.

Nuclear power in the United Kingdom

Nuclear power in the United Kingdom generates around a quarter of the country's electricity as of 2016, projected to rise to a third by 2035. The UK has 15 operational nuclear reactors at seven plants (14 advanced gas-cooled reactors (AGR) and one pressurised water reactor (PWR)), as well as nuclear reprocessing plants at Sellafield and the Tails Management Facility (TMF) operated by Urenco in Capenhurst.

The United Kingdom established the world's first civil nuclear programme, opening a nuclear power station, Calder Hall at Windscale, England, in 1956. At the peak in 1997, 26% of the nation's electricity was generated from nuclear power. Since then several reactors have closed and by 2012 the share had declined to 19%. The older AGR reactors have been life-extended, and further life-extensions across the AGR fleet are likely.In October 2010 the British Government gave permission for private suppliers to construct up to eight new nuclear power plants. The Scottish Government, with the backing of the Scottish Parliament, has stated that no new nuclear power stations will be constructed in Scotland. In March 2012, E.ON UK and RWE npower announced they would be pulling out of developing new nuclear power plants, placing the future of nuclear power in the UK in doubt. Despite this, EDF Energy is still planning to build four new reactors at two sites, with public consultation completed and initial groundwork beginning on the first two reactors, sited at Hinkley Point in Somerset. Horizon Nuclear Power have plans for 4 to 6 new reactors at their sites, Wylfa and Oldbury. Three reactors were also proposed at the Moorside Nuclear Project but the future of these is now in doubt. An agreement has also been made which allows for Chinese-designed reactors to be built on the site of the Bradwell nuclear power station.

EDF Energy owns and manages the seven currently operating reactor sites, with a combined capacity of about 9 GW. Six new plants are proposed to be built in the next few decades. All nuclear installations in the UK are overseen by the Office for Nuclear Regulation.

Scroby Sands Wind Farm

The Scroby Sands Wind Farm is a wind farm located on the Scroby Sands sandbank in the North Sea, 2.5 kilometres (1.6 mi) off the coast of Great Yarmouth in eastern England, United Kingdom. It was commissioned in March 2004 by Powergen Renewables Offshore, a division of E.ON UK. It has a nameplate capacity of 60 megawatts and is able to produce power to supply 41,000 households. Between 2005 and 2010, its capacity factor was between 26 and 32%.The farm consists of 30 wind turbines, located in water from 13 to 20 metres (43 to 66 ft) deep. Each turbine has three 40-metre (130 ft) blades that rotate around a centre-point some 60 metres (200 ft) above the mean sea level. The hollow 4.5-metre (14.8 ft) diameter steel masts that carry the turbines are piled as much as 30 metres (98 ft) into the sea bed, to provide stability on a substrate of shifting sands.

The wind turbines were designed and manufactured by a Danish firm, Vestas. Each turbine has a capacity of 2 megawatts. Turbines were installed by the Danish offshore wind farms services provider A2SEA.

Tinsley Viaduct
