==History==
The project had come about after Enercon decided to pursue a larger turbine than the 2MW E-66. For some time, Enercon worked on the E-112 project - a turbine with a generator output of 2.25x the 2MW E-66, with it eventually being available for sale sometime in 2002. Enercon then tweaked the E-112's rotor diameter from 112m to 114m, for a slight benefit in efficiency. The turbine didn't sell well - only two 4.5 MW units exist as of today, which prompted Enercon to increase the generator output from 4.5 MW to 6 MW. However, while the generator power output increase did increase sales, by 2008 sales were essentially non-existent, due to two key factors{{citation needed|date=May 2019}}:
* The fact that the wind turbines were extremely expensive to manufacture, transport and assemble,
* That Enercon was having to contend with ever-stiffening competition from fellow wind turbine builders, such as [[Senvion|Senvion SE]] and [[Vestas|Vestas Wind Systems A/S]] from Denmark.
Unfortunately for Enercon, the belief that the turbine's massive nameplate capacity would market itself to operators backfired, and it became a massive failure, with only 9 being ever installed, and this failure prompted Enercon to start tweaking the design. Enercon's new E-126 project, from the outset, didn't seem to be a massive change from the E-112, but rather an evolution of the model with a slightly higher hub height (135 m vs. 124 m) and a slightly larger rotor (127 m vs 112/114 m) with a new blade profile. For this new model, the sales were also slow, but sometime in 2011, Enercon increased the generator output from 6 MW to 7.58 MW. Sales then began to increase, with the first large-scale purchase{{citation needed|date=May 2019}} of this wind turbine model was at [[Wind_power_in_Belgium#Historical_data_Walloon_Region|Estinnes wind farm]] in Belgium, with 11 wind turbines ordered for installation.

==Specifications==
There are three variants of the E-126, of which are: EP3 low-wind, EP4 mid-wind and EP8 high-wind models. For the sake of simplicity, this article focuses on the EP8 E-126. The power output of the generator was {{nowrap|6 MW}}, but has been uprated to {{nowrap|7.58 MW}} after technical revisions were performed in 2009. Since 2011 the E-126 is available as a 7.6 MW nameplate capacity. The E-126 incorporates power electronics and offers grid stabilising capabilities.<ref>{{cite web|url=http://www.enercon.de/en-en/752.htm |title=Grid integration & Wind farm management |url-status=dead |archiveurl=https://archive.today/20130211091220/http://www.enercon.de/en-en/752.htm |archivedate=11 February 2013 |accessdate=23 February 2017}}</ref>
The weight of the foundation of the turbine tower is about 2,500 t, the tower itself 2,800 t, the machine housing 128 t, the generator 220 t, the rotor (including the blade) 364 t. The total weight is 6,012 tonnes exactly.<ref>{{cite web|url= http://www.juwi.de/fileadmin/user_upload/de/PK_2011/juwi/Hintergrund%20Repowering%20Schneebergerhof%20E%20126.pdf |title=Archived copy |accessdate=7 May 2011 |url-status=dead |archiveurl= https://web.archive.org/web/20110724121611/http://www.juwi.de/fileadmin/user_upload/de/PK_2011/juwi/Hintergrund%20Repowering%20Schneebergerhof%20E%20126.pdf |archivedate=24 July 2011 }}</ref>
The first turbine of this model was installed in [[Emden|Emden, Germany]] in 2007, at [[wde:Windpark Rysumer-Nacken|Rysumer Nacken Wind Park]].<ref>[http://www.enercon.de/en-en/66.htm Enercon E126] {{Webarchive|url=https://archive.today/20120801120556/http://www.enercon.de/en-en/66.htm |date=1 August 2012 }} from official Enercon website</ref>
The list price of one unit is $14 million plus install costs.<ref>{{cite web |url=http://cleantechnica.com/2013/08/23/worlds-most-powerful-wind-turbine-may-undergo-high-winds-coastal-tests/ |title=World's Most Powerful Wind Turbine May Undergo High Winds Tests |date=23 August 2013 |first= Jake |last=Richards |accessdate=23 February 2017}}</ref>
==Market==
In June 2012, at least 147 Enercon E-126 windturbines were operating, in construction, or nearing final approval, 35 of them completed and operating.<ref>[http://users.skynet.be/tony.aerts/images2/EnerconE-126turbines_schedule-June-2012.pdf Summary of existing and planned E-126 wind turbines] {{Webarchive|url=https://web.archive.org/web/20140201182805/http://users.skynet.be/tony.aerts/images2/EnerconE-126turbines_schedule-June-2012.pdf |date=1 February 2014 }} (based on public available www-info till June 2012)</ref>
Furthermore, during 2010-2011, onshore wind farm projects still in their early design processes were considering wind turbines of the 2-3.5 MW class, or wind turbines of the 5-8 MW class. This approach is at least applied in the Netherlands. Examples for this trend are found for instance in the preliminary research for the "Wind farm de Drentse Monden"<ref>{{cite web|url=http://www.dedrentsemonden.com/|title=Home - Windpark Drentse Monden Oostermoer|work=Windpark Drentse Monden Oostermoer|access-date=21 October 2011|archive-date=9 November 2013|archive-url=https://web.archive.org/web/20131109181834/http://www.dedrentsemonden.com/|url-status=dead}}</ref> aiming at 300-450 MW with possibly 50-60 E-126/7.5 MW turbines, "Wind farm N33"<ref>{{cite web|url=http://www.windpark-n33.nl |title=Windpark n33|publisher=}}</ref> aiming at >120 MW with possibly 15-40 E-126/7.5 MW turbines, "Wind farm Krammer"<ref>{{cite web|url=http://www.windparkkrammer.nl|title=Home - WindPark Krammer|work=WindPark Krammer}}</ref> aiming at >100 MW with possibly 11-21 E-126/7.5 MW turbines, "Wind farm Wieringermeer"<ref>{{cite web |url=http://www.windplanwieringermeer.nl |title=Index of / |publisher= |access-date=8 December 2019 |archive-url=https://web.archive.org/web/20160306003401/http://windplanwieringermeer.nl/ |archive-date=6 March 2016 |url-status=dead }}</ref> aiming 200-400 MW with possibly 60 or more 6+ MW turbines (in that case possibly Repower 6M/6.15MW).

=== Sweden: Markbygden Wind Farm ===
The [[Markbygden Wind Farm]] is planned to have 1,101 turbines covering 500&nbsp;km<sup>2</sup>,  to generate 4,000 MW and an annual yield up to 12 TWh, making it one of the world's largest wind farms.
Under construction in northern Sweden, it will contain a mix of Enercon E-126 7.58 MW wind turbines and Enercon E-101 3.05 MW wind turbines, the exact number of each type to be determined by further studies.<ref>[http://www.ordons.com/europe/nordic-countries/480-sweden-to-build-worlds-largest-windfarm.html Markbygden Wind Farm] {{Webarchive|url=https://web.archive.org/web/20120308060704/http://www.ordons.com/europe/nordic-countries/480-sweden-to-build-worlds-largest-windfarm.html |date=8 March 2012 }} Sweden to build world's largest windfarm, Ordons News, April 2009</ref>

=== Netherlands: Windpark Noordoostpolder ===
The Netherlands government gave its final approval on 6 January 2011 for the '[[Windpark Noordoostpolder]], part of which would consist of 38 Enercon E-126 7.58 MW wind turbines. An ultimate case for the highest Court of state by opponents was closed on 8 February 2012, confirming the government decision. In 2011 it was expected preparatory works would start before the summer of 2012.<ref>[http://www.windparknoordoostpolder.nl/ 2011 Windpark Noordoostpolder] (Dutch)</ref>
=== France: Wind Farm Le Mont des 4 Faux (Le Mont des 4 Faux Parc Éolien) ===
In [[France]], a pending approval for the wind farm 'Le Mont des 4 Faux', consisting of an initial number of 52 Enercon E-126 7.58 MW wind turbines but in April 2012 reduced to a new variant of 47 turbines (deleting one 5-unit row in order to meet some ornithological concerns), is considered to be confirmed as such 47 turbines wind farm in 2012. This E-126 wind farm is situated between [[Juniville]] and [[Machault, Ardennes|Machault]], at the southern side of the French [[Ardennes]], near [[Reims]].<ref>[http://www.windvision.be/projets-en-france/le-mont-des-4-faux/ Le projet "Le Mont des 4 Faux"] {{Webarchive|url=https://web.archive.org/web/20110920180451/http://www.windvision.be/projets-en-france/le-mont-des-4-faux/ |date=20 September 2011 }} (French)</ref><ref>[http://www.ale08.org/Reunion-publique-d-information-sur.html?var_recherche=Le%20Mont%20des%204%20Faux Réunion publique d’information sur le projet éolien du Mont des4 faux à Ville-sur-Retourne]</ref> The project developer is the company Windvision.<ref>[http://windvision.com/fileadmin/template/Contenu/Projets_France/PAR009FR/WINDVISION_Resume_du_projet.pdf Flyer (pdf)] {{dead link|date=April 2016 |fix-attempted=yes}}</ref>
