The economy in NRW: Statistics and facts
When people talk about North Rhine-Westphalia, they often associate it with the Ruhr region – characterized by coal and steel. Although the Rhine-Ruhr region is still an industrial heartland of the state and the steel industry still exists, it has lost its traditional monopoly position and coal mining has been discontinued.
Since the 1960s, the Ruhr region has been undergoing a serious structural change – combined with the departure of old industries and a fundamental reorientation. It is not over. In 2019 goods and services worth around 711 billion euros were produced in NRW. This means that North Rhine-Westphalia surpasses all other German states. A good one in five euros generated in Germany comes from the Rhine and Ruhr. In terms of economic output per capita, however, NRW only ranks 7th in a state comparison.
Today, industry accounts for almost one fifth of North Rhine-Westphalia’s economic output. Strong industrial sectors in the state are mechanical engineering (with around 1,600 predominantly medium-sized companies); automotive production (Ford in Cologne) and supply (Hella, among others), chemical industry (especially Bayer in Leverkusen, Evonik Industries in Essen), electrical engineering and the electrical industry. ThyssenKrupp in Essen stands for steel tradition and is Germany’s largest steel producer. 44 percent of German steel comes from NRW.
The state is also home to major utilities such as E.ON, RWE and Steag. Almost a third of Germany’s electricity comes from NRW. Trade accounts for almost a quarter of North Rhine-Westphalia’s economic power. Of the 50 largest German trading companies, every second one is located in NRW, including Aldi, Metro and Rewe. The financial and corporate services sector is at least as strong. Some well-known insurance companies (including Ergo, Gothaer, Signal/Iduna) have their headquarters in NRW.
List of the 5 largest companies in North Rhine-Westphalia
North Rhine-Westphalia is Germany’s most populous federal state and contributes a good 20 percent to Germany’s economic output – more than any other state. Companies of world renown have their headquarters on the Rhine and Ruhr. These are the five largest:
Place 1: Deutsche Telekom AG, Bonn: 101 billion euros in revenue (2020)
Deutsche Telekom was created from Deutsche Bundespost TELEKOM in 1995 – the final step in the privatization of the former state-owned company. Today, Telekom is Europe’s largest telecommunications provider and is one of the TOP 100 listed companies worldwide. The group is divided into six divisions: Germany (Telekom Deutschland), Europe, T-Systems, USA (T-Mobile US), Group Development and GHS (Group Headquarters and Shared Services). Telekom operates fixed and mobile communications networks and offers telephony, Internet access and other digital services based on these networks. The Group has over 225,000 employees.
Place 2: Deutsche Post AG, Bonn: 66.8 billion euros in revenue (2020)
Like Deutsche Telekom, Deutsche Post emerged from the former Deutsche Bundespost in 1995. Since 2015, its external identity has been “Deutsche Post DHL Group”. The national postal business operates under the brands “Deutsche Post” (letter) and “DHL” (parcel). The international logistics business also operates under the “DHL” brand. The operating business is divided into the Post & Parcel Germany, DHL eCommerce Solutions, Express, Global Forwarding, Freight and Supply Chain divisions. Deutsche Post is a leading global logistics service provider with a good 570,000 employees.
Place 3: Uniper SE, Düsseldorf: 51.0 billion euros in revenue (2020)
Uniper was formed in 2016 by spinning off its conventional power generation business from energy group E.ON. Since 2020, Uniper has been majority-owned by the Finnish energy company Fortum, in which the Finnish state has a stake of just over 50 percent. Uniper is one of Europe’s largest power producers with core markets in Germany, the Benelux countries, the United Kingdom, and Sweden. In Russia, Uniper operates five power plants and meets about five percent of Russia’s electricity needs. The company also participates in global energy trading and has nearly 12,000 employees.
Place 4: Bayer AG, Leverkusen: 41.4 billion euros in sales (2020)
Bayer was founded as early as 1863 in what is now Wuppertal, and since 1895 its headquarters have been located in Leverkusen, north of Cologne. Bayer is a major global chemical and pharmaceutical group. Its business comprises the three divisions Pharmaceuticals, Consumer Health and Crop Science – each organized in its own subsidiaries since 2002. A quantum leap in 2018 was the acquisition of the US seed and herbicide company Monsanto. This brought the active ingredient glyphosate into the group as a “legacy”. The Bayer Group has almost 100,000 employees and operates on a global scale.
Place 5: thyssenkrupp AG, Essen: 28.9 billion euros in sales (2019/2020)
The merger of Friedrich Krupp AG Hoesch-Krupp with Thyssen AG in 1999 created thyssenkrupp AG – an industrial group organized into four divisions focusing on steel production and processing. The thyssenkrupp business is divided into the business areas Steel Europe, Material Services, Industrial Solutions and Components Technology. A planned merger with the Indian steel group Tata Steel did not materialize in 2019. The elevator business was sold in 2020. More than 100,000 employees still work at thyssenkrupp today. The company is Germany’s largest steel producer.

In most cases we achieve a data coverage of over 90%. If you want to know the exact coverage of the list – e.g. how many e-mail addresses are available – our team will be happy to help you.

Future free updates will also be sent to you by e-mail. If you pay in advance, you will receive the list after the amount has been credited to our account or you have sent us a bank transfer receipt.
We have noted the last update date in the product description at the top of the page. We update our lists regularly. Our customers receive free updates and additions to the list for at least 12 months.
Our lists contain – if publicly available – address, telephone number, e-mail addresses and management names of the listed companies. For privacy reasons, we may only include information that is publicly available or provided by the companies. If no data points are available, there is an “n.a.” in the corresponding field.
Due to the DSGVO our lists do not contain personal e-mail addresses and telephone numbers. Our lists contain publicly available contact data or contact data provided by the companies (e-mail address, telephone number, postal address, names of directors).
Our lists do not contain any personal contact data that is specifically protected by the European Data Protection Regulation (DSGVO). Our lists always contain publicly accessible data points (official registers such as the Commercial Register or the Federal Gazette, Internet, company websites) or data provided voluntarily by companies and are therefore harmless.
In Germany, contact is regulated by §7 UWG. Thus, postal advertising in the B2B sector is generally permitted. Contacting by telephone is permitted if the business contact is presumably interested. This can also be accepted for e-mail contact, as long as the contact is made once and the contact is not included in newsletters without being asked.
Important note: We are not lawyers and cannot make legally binding statements. If you have any open questions, please feel free to contact us.
The companies included in the lists can be contacted in various ways – by telephone, postal letter, e-mail, networks such as LinkedIn, jointly attended trade fairs. In order to establish successful contacts, it is particularly important to work on individualized addresses tailored to the respective companies. Mass letters are rarely successful. Instead, our customers are most successful when they adapt to the companies included in our lists, obtain information and then address them in a customized manner. Another successful approach is to contact them via LinkedIn, for example, by selecting the right contact person from our list and then addressing them via a consistent starting point. Intros” that are mediated via shared contacts are also a good step towards establishing contact. Also possible: at trade fairs visited together, you can use the trade fair lists to search specifically for companies included in the lists and make appointments for meetings.
In general: the more effort is put into the individual approach, the more successful it is. Think about what suitable starting points are, how you can deliver added value and show the addressed companies that you put a lot of effort into the contact. Many of our customers have already built up valuable and successful business relationships.
