Ecotricity is an energy company based in Stroud, Gloucestershire, England specialising in selling green energy to consumers that it primarily generates from its 70 megawatt[2] wind power portfolio - the company prefers the term windmill rather than wind turbine.[3] It is built on the principle of heavily reinvesting its profit in building more of its own green energy generation.[4]


Ecotricity was started by Dale Vince in 1995, with a single wind turbine he had used to power an old army truck in which he lived on a hill near Stroud.[5]

From this, Vince went on to commercially build wind-monitoring equipment, which the company still does today using the name Nexgen.[6] Ecotricity then started generation with a 40-metre turbine in 1996, which at the time was the largest in the country.[7]

In 2007, Vince ran an advertisement on the back page of The Guardian newspaper inviting Richard Branson to his house to discuss solutions to climate change over a carbon-free breakfast. The ad ran the day after Branson appeared on TV with American former vice president Al Gore, who had managed to persuade Branson that climate change was an issue. The ad included Vince’s personal mobile phone number.[8]

Ecotricity was a winner in the 2007 Ashden Awards for sustainable energy. The awards congratulated Ecotricity for its environmental contribution, saying 'The company's turbines are delivering 46 GW·h/yr of renewable electricity and avoiding around 46,000 tonnes of CO2 emissions a year. The installed capacity is expected to double by the end of 2007.'[9]

In July 2009, Ecotricity started legal proceedings[10] against French power company EDF Energy for the alleged misuse of the green Union Flag logo, used to promote EDF's Team Green Britain campaign. Ecotricity had previously used a green Union flag in its own advertising and claimed confused customers had contacted it to ask why Ecotricity was co-operating with EDF.

In January 2012 it was announced that Ecotricity has invested in the development of Searaser pump-to-shore wave energy machines,[11] and in June said they were to be deployed in the autumn of that year.[12] In October 2014 Ecotricity and marine consultants DNV GL were are moving from laboratory trials to sea trials.[13]

In October 2014 it was announced that Ecotricity has partnered with Skanska to build and finance new turbines to add a further 100MW to its existing 70 MW capacity,[14] The following month, the company decided not to attempt new planning applications in England because of the political climate, instead concentrating on Scotland.[15] It went on to spin its small turbine manufacturer out into a subsidiary called Britwind,[16] which, in collaboration with a local company offered free electricity to crofters in return for installing a small turbine, keeping any excess power generated.[17]

In March 2015 Ecotricity announced it had refinanced its existing wind farms with the aim of using the extra capital to expand production to 100 megawatts by November 2016[18]


Before August 2013, Ecotricity ran a mix of fuels. Ecotricity's proportion of renewable energy rose from 24.1% in 2007 to 51.1% in 2011 (compared with a national average of 7.9%), with plans for a further increase to 60% by 2012[19]

In the past, a substantial proportion of the electricity (25.9% in 2007) sold by Ecotricity to customers came from nuclear sources, which help reduce carbon emissions. This proportion had decreased to 16% by 2010, and 2.6% by 2011.[19] Ecotricity also provided a 100% renewable energy tariff called New Energy Plus, in which renewable energy was bought in from other suppliers to top up renewable energy produced by Ecotricity.[20]


In Conisholme in Lincolnshire on 8 January 2009 two of the blades of one of the company's turbines were damaged.[21] In February 2013 the go-ahead was given for Ecotricity to build its largest windfarm, a 66 megawatt, 22 turbine farm at Heckington Fen in Lincolnshire[22]

In February 2013 Ecotricity revealed a prototype 6 kW vertical axis wind turbine called the "urbine".[23]


Ecotricity also produces solar energy, with its first 'sun park' opening in 2011.[24] In April 2016 it bought SunEdison's UK business supplying domestic solar panels.[25]


From May 2010 it became the first UK company to supply eco-friendly gas, produced in the Netherlands by anaerobic digestion of sugar beet waste[1][26] and by 2017 it plans to have its own digesters fed by locally sourced grass from marginal land of grade 3 or poorer. The first will produce 78.8GWh a year from 75,000t of grass and forage rye silage.[27][28]

In August 2015 Ecotricity announced plans to build an anaerobic digester at Sparsholt College in Hampshire that will take grasscuttings from local farms and supply the resulting six megawatts[29] of gas to the grid[30] with the overall aim of training students in the technology. This joins the first announced in Gloucestershire in April[27] and was followed by a third three megawatt[31] plant announced in August in Somerset.[32]

On 25 April 2016 planning permission for the site at Sparsholt College was refused.[33] In July 2016, a new application was made to build the facility at the college site, which was approved in October 2016.[34] The new proposal included "[...] new and revised traffic data and assessment, new traffic plans to keep vehicle movements away from Sparsholt village and a commitment to protect local road infrastructure.". Also, "[Ecotricity] consulted representatives of the nearby parish councils and incorporated their requests, wherever possible into the routing plans and operational controls."

Side projects[edit]


Ecotricity is the sponsor of the Ecotricity Greenbird, a land yacht that set a new world land speed record for wind-powered vehicles on 26 March 2009 on the dry Lake Ivanpah.

Ecotricity has built an electric sports car called Nemesis that was built as a demonstration of what electric cars are capable of: an endurance trip from Land's End to John o' Groats is planned recharging only from electricity produced by wind power.[35] In September 2012 the car broke the UK electric land speed record reaching an average speed of 151 mph[36]

Vehicle recharging[edit]

In July 2011 Ecotricity launched a free vehicle charging network sited around the country at 14 of the Welcome Break Motorway service areas, linking London in the south with Exeter in the west and Edinburgh in the north.[37] The charging points were initially equipped with both a UK standard 13amp domestic socket and a high power IEC 62196 32amp 3-phase socket. It is to build wind turbines and vehicle charging points at RoadChef sites across the UK to allow vehicles to recharge directly from the wind.[7]

In October 2012 the company started to add 50 kW CHAdeMO fast charging to its charging stations allowing compatible cars to recharge within 30 minutes.[38] In April 2014 it was announced that it would be adding support for Combined Charging System connectors from May[39] and the September had over 120 chargers. In May 2014 it brought an interim high-court injunction against electric car manufacturer Tesla over its vehicle charging network;[40][41] this was resolved in an out of court settlement.[42]

In 2014 the Ecotricity vehicle charging network had sporadic software problems to do with the addition of a new connector which left some chargers not working or not connecting to specific cars.[43]

As of December 2014 it covered 90% of the motorway service stations including Land's End and John o' Groats.[44] By December 2015 it had 6,500 members using it once a week or more, and the network, which had hitherto been free of charge, would henceforth require payment.[45] In an interview in March 2016 Vince announced that payment would start in a couple of months and the money from it would be used to improve and extend the network.[46]

From 11 July 2016 Ecotricity started charging £5 for a 20-minute fast-charge, later changed to £6 for 30 minutes[47] but kept it free for customers of Ecotricity.[48]

Distributed energy storage[edit]

Ecotricity has investigated supplying 100 houses with an[49] internet-connected grid energy storage system that will take the homes off the grid at peak times.[50][51][52]

Mobile phones[edit]

In September 2013, Ecotricity planned to launch a mobile phone network called Ecotalk.[52] In March 2016, Vince said[46] that electricity costs will all be covered by "green electricity" and some of the profts would go towards returning land to the wild. In February 2017 a Mobile virtual network operator announced it had been chosen as their partner in this and that the technical infrastructure would be supplied by Three UK

Small turbine manufacture[edit]

In May 2014, Ecotricity rescued Evance, a manufacturer of small (5 kW) wind turbines, from administration,[53] saving the company's 29 jobs. [54] Branded "Brit Wind" in January 2017 they announced one million pounds worth of sales to Japan as well as sales to France, Norway, Denmark, the USA and Belgium.[55]

Political donations[edit]

The company has donated to several political parties that support subsidies for renewable energy. In November 2013 it donated £20,000 to the Green Party.[56] On 10 February 2015 Ecotricity announced that it would be donating £250,000 to the electoral fighting fund of the UK Labour Party.[57] This decision alienated some of its customers, in particular supporters of the Green Party as they felt some Labour policies are at odds with Ecotricity's avowed green ethical stance.[58]

In fact Ecotricity had already donated £120,000[56] to Labour in November 2014, including £20,000 to the local group in Stroud[56] which was trying (unsuccessfully) to unseat Neil Carmichael, an opponent of wind farms in Gloucestershire. In the six months before the 2015 general election Ecotricity donated a total of £380,000 to Labour.[56] The day after the election of 7 May 2015 the company donated £50,000[56] to the Liberal Democrats, including £20,000[56] to the group in the Kingston upon Thames constituency which had been lost by Ed Davey, the pro-renewables Secretary of State for Energy and Climate Change.
