[1] Enercon has production facilities in Germany (Aurich, Emden and Magdeburg), Brazil, India, Canada, Turkey and Portugal.

[3] As of December 2017[update], Enercon had installed more than 26,300 wind turbines, with a power generating capacity exceeding 43 GW.

In fact, the companies belong to the Grp Aloys B A Wobben Breeze Trust based in Luxembourg and the British Virgin Islands through nested ownership structures.

At the time, the NDR assumed that the structure was set up so that Aloys Wobben could skim off his profits but not have to make any social obligations to his employees.

Thus the large Enercon generators lead to high tower head masses, and construction and logistical challenges.

In 2022, the first integrated box-shaped nacelles with inverter and transformer reduced logistics - all previous Enercon turbines had power systems in the tower base.

[15][16] Enercon was rumored to have been ready to supply turbines to Germany's Alpha Ventus offshore wind farm and to a near-shore park near Wilhelmshaven but did not do so.

[34][35] In a dispute before the United States International Trade Commission, Enercon did not challenge the validity of the US patent but argued that their technology was not affected.

[36] Later, a cross patent agreement was made with the competitor General Electric, the successor of Kenetech, after similar claims of Enercon against GE.

[37] The aim of the alleged industrial espionage against Enercon was the forwarding of details of Wobben's generator technology to a US firm.

During the time Enercon part-owned the rail line, the company undertook large scale investments in its infrastructure.
