Directorate Change

Scottish & Southern Energy PLC 07 March 2007 SCOTTISH AND SOUTHERN ENERGY PLC BOARD APPOINTMENTS Scottish and Southern Energy plc ('SSE') has appointed Richard Gillingwater as a non-Executive Director, with effect from 25 May 2007. Richard is Dean of the Cass Business School. He was previously Chief Executive of the Shareholder Executive, from which he stepped down in February, and before that held a number of appointments in the City of London, where he was Chairman of CSFB European Investment Banking. As a former Crown servant, his appointment has been authorised by the Advisory Committee on Public Appointments. Richard will be proposed for election to the Board at SSE's Annual General Meeting on 26 July 2007, along with Nick Baldwin, who was appointed to the Board in September 2006. David Payne, currently Senior Independent Director, will retire at the AGM and does not wish to be re-elected. David joined the Board as a non-Executive Director of Scottish Hydro Electric in 1998. He became Deputy Chairman of SSE in 2005 and will complete nine years' service in June. After these changes take effect, the Board of SSE will continue to have four Executive Directors and five independent non-Executive Directors in addition to the Chairman. Sir Robert Smith, Chairman of SSE, said: 'I am delighted that Richard will join our Board. He has long-standing connections with SSE, stemming from the merger which created the company nearly a decade ago, and will bring a wealth of experience and knowledge to our deliberations which will complement very well the contributions of the other Directors. David's background in energy, and his shrewd and perceptive understanding of complex issues, have made him an outstanding Director. The Board has benefited enormously from his participation. Everyone at SSE would like to wish him well when he steps down from the Board in July.'
