Laetitia Griffith to join TenneT Supervisory Board

On 1 July 2015, Laetitia Griffith will be appointed to the Supervisory Board of TenneT Holding B.V.

Ms. Griffith (1965) not only brings legal expertise to the job, but also extensive experience in politics as well as public and corporate governance. Her career includes positions as a member of the Amsterdam City Executive (responsible for Finance, Economic Affairs, Airport, ICT, Procurement and Participations) and as a member of parliament. Since 2012, she has been working as State Councillor in the Advisory Division of the Council of State.

“TenneT operates at the intersection of social, political and economic interests against the background of the international energy market, so it should almost go without saying that I consider it an honour to be able to join TenneT's Supervisory Board”, said Ms. Griffith.

From 1 July 2015, TenneT’s Supervisory Board will comprise the following six members: Aad Veenman (chairman), Rien Zwitserloot, Pieter Verboom, Stephanie Hottenhuis, Hans Fischer, and Laetitia Griffith.
