Energy & Utilities Expert

Colette Lewiner

A seasoned Energy & Utilities expert whose experience spans research, industrial operations, consulting and corporate governance. She now supports companies in two practices.  As an independent consultant, through her company Cowin, on energy strategy, the energy transition, nuclear power and governance; and as a non-executive director of listed and non-listed companies for more than 20 years, where she has chaired and chairs Audit and Risk, and Appointment, Remuneration and Governance committees.

Career

1964–1978
Education and research
Entered the École Normale Supérieure (Sèvres) in 1964 as a physics student and passed the agrégation of physics in 1968. As assistant professor and researcher at the University of Paris VII from 1969 to 1979, carried out research in solid-state physics on electric and magnetic effects in semiconductors at the microscopic scale — a 1973 thesis on the anomalous Hall effect, supervised by Professor Philippe Nozières, followed by work on semi-magnetic semiconductors and hot electrons, in close exchange with European, Soviet and American researchers. Published around 20 articles in renowned physics journals.
1979–1992
Électricité de France (EDF)
Joined in November 1979 as Secretary General to the Research and Development Executive Vice President. Moved in 1982 to the Fuel Procurement Department — fuel oil, coal, gas, uranium and enrichment purchases — and was appointed head of the department in 1987. With a purchasing budget of 17 billion French francs (about $3.5 billion), the department was a leading force on international uranium and nuclear services markets. On 15 February 1989, created the Development and Commercial Strategy Division, becoming EDF's first woman Executive Vice President.
1992–1998
SGN-Eurisys (Cogema, later Areva)
Chairman and Chief Executive of the SGN Eurisys Group, the world leader in nuclear fuel-cycle engineering — about $1 billion in revenue, 9,000 employees including 3,000 engineers, operating in Europe, North America, Japan, Korea and Indonesia. Oversaw major projects at La Hague and Melox in France and Rokkasho-Mura in Japan; won the 1996 US Department of Energy clean-up contract for the Hanford site with Fluor Daniel and Lockheed Martin.
1998–present
Capgemini
General Manager of the Utilities Global Market Unit from 1998; Corporate Vice President and Global Leader of the Energy, Utilities and Chemicals sector from May 2000 — the sector grew from 4% of group revenue in 1998 to 11% in 2010, with 11,000 collaborators across North America, Europe and Asia-Pacific. Created the European Energy Markets Observatory in 2002, now the World Energy Markets Observatory (WEMO), and has overseen more than twenty annual editions as its author and spokesperson. Created and led the group's global marketing unit from 2004 to 2008. Energy Advisor to Capgemini's Chairman since July 2012, remaining WEMO's author and spokesperson. 
2012–present
Cowin
Founder and general manager of Cowin, her own independent consulting company on energy strategy, the energy transition, nuclear power and governance matters.

Institutional roles

Member of the European Union Advisory Group on Energy (2008–2012) and of the French Conseil Stratégique de la Recherche (2013–2017), appointed by the Prime Minister. In 2004, appointed to the CSTI (Conseil Supérieur des Technologies de l'Information), a think tank on communication and information technologies. In 2007, asked by the French energy regulator (CRE) to launch and chair a high-level working group on liquefied natural gas terminal regulation in Europe and France. Also served on the board of the École Normale Supérieure. Elected to the French Academy of Technologies in September 2002.

Women in science

A former president of the European Nuclear Society and of NucNet, the first international communication agency on nuclear topics, created the WIN association (Women in Nuclear) in 1993, to give women in the nuclear industry a platform for exchanges and to encourage young women into the field — today a flourishing worldwide organisation.

In 2021, with the Télémaque association, founded the Judith and Maurice De Botton scholarship, in homage to her parents, to help young women from disadvantaged backgrounds pursue scientific studies.

Energy convictions

Nuclear power, with hydropower and geothermal, is the only dispatchable, sovereign, low-carbon source of electricity and should stay central to the mix in industrialised countries. Generation 3 reactors and SMRs, if competitive, will make up the future fleet.
Electricity mix integrates renewables with dispatchable sources, and grid balance will depend on  progress in storage — batteries, pumped hydro, hydrogen — and customer's consumption flexibility.
AI, electric mobility and increased electrification of usages are reshaping the utilities operations. Regulations must be streamlined and electrical grids must adapt, and  be protected against  extreme weather events and cyberattacks.
Global warming: limiting it depends  on developing countries managing their energy transition while widening access to electricity — about 800 million people still have none. Infrastructures adaptation to climate change consequences is now urgent.

Awards & honours

For colleagues outside France: the Légion d'honneur (Legion of Honour) is France's highest order of merit, civil and military, founded by Napoleon in 1802; the Ordre national du Mérite (National Order of Merit) ranks just below it, recognising distinguished service to the nation. Both are conferred in ascending grades — Knight, Officer, Commander, Grand Officer.

Physics & publications

In 1968, passed the agrégation in physics for teachers in France, then began research with Professor Philippe Nozières while teaching at the Paris Faculty of Science (later Université Paris VII). Research in solid-state physics focused on electric and magnetic effects in semiconductors at microscopic scale. In March 1973, published a PhD thesis on the anomalous Hall effect in semi-magnetic semiconductors, continuing research on semi-magnetic semiconductors and hot electrons — theoretical work always linked to experiments at École Polytechnique and École Normale, and to exchanges with European, Soviet and American researchers.
