A life between laboratory, parliament and the power grid

Katherina Reiche was born on 16 July 1973 in Luckenwalde, a district town about 50 kilometres south of Berlin. At the time it belonged to the GDR's Bezirk Potsdam. Her family background was industrial and scientific. According to the biographical reference Munzinger and press reporting, her mother is a chemist and her father a chemical engineer. Her grandfather, Helmut Schulze, founded a plastics-processing firm in Luckenwalde in 1946. The state nationalised it in 1972, and after reunification it was reprivatised and run by the family.

She was sixteen when the Berlin Wall fell in November 1989, so she finished school in a country that no longer existed in the form she had grown up in. She took her Abitur in 1992 at the Gymnasium in Luckenwalde. The town's most famous son is the student leader Rudi Dutschke. In 2002 Der Spiegel reported that she had once named him "the town's greatest son" when asked about role models. It was an unexpected answer from a young Christian Democrat.

Her official CVs list her as Protestant, a detail that later counted in national politics. In 2002 Der Spiegel described her selection for the CDU/CSU campaign team as giving the Union a face that was "young, female, east German and Protestant".

Reiche studied chemistry at the newly founded University of Potsdam from 1992 to 1997. Her studies included time abroad. In 1995 she was a research assistant at the Institute of Chemistry and Biology at Clarkson University in Potsdam, New York, and in 1997 she made two research stays at the University of Turku in Finland. She graduated as a Diplom-Chemikerin in 1997; her association CV records the grade as 1.0, the highest possible. She then worked as a research associate at the University of Potsdam until her election to the Bundestag in 1998.

She holds no doctorate. In April 2025 MCI Management Center Innsbruck appointed her an honorary professor, having previously had her as chair of its advisory board.

Analysis Her technical training is often cited in profiles to explain her ease with energy-system questions. Her first parliamentary portfolios were education, research and bioethics, and later environment and nuclear safety. These were fields where scientific literacy is directly useful.

Education & scientific background

Her political engagement began at university. In 1992 she was a founding member of the Christian Democratic student association RCDS at the University of Potsdam, and the same year she joined the Junge Union and its Brandenburg executive. She joined the CDU itself in 1996. She chaired the Frauen Union in the Potsdam-Mittelmark district and sat on the CDU district board there.

In the federal election of 27 September 1998, which ended sixteen years of government under Helmut Kohl, she stood in the Potsdam constituency and on the CDU's Brandenburg state list. The constituency went to the SPD, but she entered the Bundestag via the list on 26 October 1998, aged 25.

Political beginnings in detail

Reiche sat in the Bundestag for five legislative periods. She entered four times through the Brandenburg list and won the Potsdam – Potsdam-Mittelmark II – Teltow-Fläming II constituency directly in 2013. That year she took 32.6 per cent of first votes, beating the SPD incumbent Andrea Wicklein by 730 votes, after finishing third in the same seat in 2005 and 2009.

Within the CDU/CSU parliamentary group she rose quickly. From 2002 to 2005 she chaired the group's working group on education and research. In the 2001–2002 debate on importing human embryonic stem cells, she co-sponsored, with Wolfgang Schäuble, Rita Süssmuth and Friedbert Pflüger, the motion that went furthest in permitting controlled imports for research. From late 2005 to 2009, during the first grand coalition under Angela Merkel, she was a deputy chair of the parliamentary group, responsible for education and research and for environment, nature conservation and nuclear safety.

She left parliament at the end of 4 September 2015 to take up a post in the energy industry. Because the CDU's Brandenburg list was exhausted, her seat stayed vacant until the 2017 election.

The Bundestag profile · Parliamentary work

In early July 2002 the CDU/CSU chancellor candidate Edmund Stoiber named the 28-year-old Reiche to his campaign "Kompetenzteam", alongside figures such as Lothar Späth, Friedrich Merz, Annette Schavan and Wolfgang Schäuble. She was originally to cover family policy. After objections from church circles and conservative Union politicians, "family" was removed from her brief, and she was put in charge of youth and women's policy.

Criticism The objections centred on her being an unmarried mother expecting a second child, and on her support for embryonic stem-cell research. Der Spiegel reported that the German Bishops' Conference had intervened with the Union leadership, and Cologne's Cardinal Joachim Meisner suggested the party drop the "C" from its name. Stoiber and the CDU leader Angela Merkel publicly defended her. The SPD women's association mocked what it called her "demotion".

Her second daughter was born on 26 August 2002, and she married in 2003. The Union lost the election of 22 September 2002, so the team never took office. The episode nonetheless made her nationally known. Commentators read it as an early test of how far the Union would accept modern family realities.

The controversy, analysed

When the CDU/CSU formed a coalition with the FDP in 2009, Reiche became Parliamentary State Secretary at the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. She served under Norbert Röttgen and, from May 2012, Peter Altmaier. These were the years of the Fukushima reversal. After she had voted for the extension of nuclear plant lifetimes in autumn 2010, she voted on 30 June 2011 for the phase-out of nuclear power by 2022. In March 2012 she defended in the Bundestag the government's cuts to solar feed-in support, arguing that a mass market could not "be permanently fed by subsidies".

After the 2013 election she moved to the new Federal Ministry of Transport and Digital Infrastructure under Alexander Dobrindt. She served there as parliamentary state secretary, in a caretaker capacity from 22 October and formally from 17 December 2013. Her areas included road safety, electromobility and the eastern German states, and she chaired the advisory board of the air navigation service DFS. Her successor, Norbert Barthle, was appointed on 11 February 2015.

Federal government roles in depth

In February 2015 the Verband kommunaler Unternehmen (VKU), the association of Germany's municipal utilities, elected Reiche its chief executive. She took up the post in September 2015. The move from a ministry to an industry association, while still a member of parliament, intensified the national debate about cooling-off periods for departing politicians. At VKU she represented the companies that run much of Germany's local energy, water and waste infrastructure. From 2016 to 2019 she also served as president of CEEP, the European association of public-service employers. In 2018–2019 she sat on the federal commission on growth, structural change and employment (the "coal commission"), which recommended ending coal power in Germany by 2038 at the latest.

On 1 January 2020 she became chief executive of Westenergie, E.ON’s largest subsidiary, headquartered in Essen. By its own account the group’s grid companies operate around 196,000 kilometres of power lines and 37,000 kilometres of gas network in North Rhine-Westphalia, Rhineland-Palatinate and Lower Saxony, with around 11,000 employees. In 2020 the federal government also appointed her chair of the newly created National Hydrogen Council, the expert body advising on the National Hydrogen Strategy. She held both roles until she entered the government in 2025.

The professional career

Reiche had been out of party politics for a decade when the CDU leader Friedrich Merz presented her as minister-designate on 28 April 2025. Clean Energy Wire called her his "surprise pick". The CDU general secretary Carsten Linnemann, long tipped for the economics post, had said on 15 April that he would stay in the party job. She was sworn in on 6 May 2025, succeeding Robert Habeck. The ministry was renamed the Federal Ministry for Economic Affairs and Energy (BMWE), and climate protection moved to the environment ministry. She holds no seat in the Bundestag.

Her first eighteen months have been dominated by energy costs and supply security. In September 2025 she presented an external "monitoring report" on the energy transition with a ten-point plan built around cost efficiency. From 1 January 2026 a relief package abolished the gas storage levy, subsidised transmission-grid fees with €6.5 billion and cut electricity tax for manufacturing to the EU minimum. The European Commission approved an industrial electricity price in April 2026. A capacity law providing for 12 GW of new, hydrogen-ready controllable power plants passed the Bundestag in July 2026, as did a heating law that abolishes the 65 per cent renewables rule for new heating systems. A reform of renewable support that ends fixed feed-in tariffs for new small rooftop solar systems is before parliament.

Criticism The same period brought sustained controversy. Critics raised possible conflicts of interest given her Westenergie past, reports that parts of her ten-point plan echoed utility position papers, and a Spiegel report on gas-plant auction proposals the ministry had solicited from EnBW. Her call for longer working lives drew fire, as did her plans for rooftop solar. Environmental groups accuse her of slowing the energy transition. Supporters, including major industry associations, credit her with a more cost-conscious course. The 2026 energy price shock that followed the closure of the Strait of Hormuz sharpened both arguments.

The ministry, in detail · Controversies

Analysis Few German ministers have held a leading position on both sides of the regulatory line in the sector they now oversee. Reiche wrote energy and environmental legislation as a parliamentarian and state secretary, then lobbied for and ran regulated infrastructure companies, and returned to government to set the rules again. Supporters regard this as the expertise needed to manage an energy system under cost pressure. Critics see the same record as a source of potential conflicts of interest and of a policy tilt towards incumbent grid and gas interests. Both readings are documented on this site.

Her career also traces a broader German story: an east German woman born under the GDR who rose in a western-dominated party and moved between politics and industry, through the arguments over nuclear power, coal, solar subsidies, hydrogen and gas.
