This research project on the future of coal-fired power generation was funded by the European Climate Foundation (ECF). Matt Phillips from the ECF played a key role in the early stages of the development of the project, as well as providing useful information and comments. The author would like to thank all those who agreed to be interviewed for this project (listed in Annex A), some of whom also gave valuable feedback on earlier drafts. This report is based, in part, on background analysis commissioned from Will Blyth of Oxford Energy Associates, available as a separate report on the ippr website at www.ippr.org. He also made valuable contributions throughout the project. Nicola Kircup at the Energy Markets team at BERR kindly provided information on effective capacity margins. The analysis also benefited from comments by participants at an ippr event on the framework for investment in low-carbon electricity held in January 2008, and an ippr seminar on the future of coal- fired power generation in May 2008. In addition, the author would like to thank Simon Retallack, Howard Reed, Danny Sriskandarajah, Lisa Harker, Matt Jackson, Miguel Castro Coelho, Georgina Kyriacou, Kelly O’Sullivan and other colleagues at ippr for their comments. However, none of the above should bear responsibility for the views expressed in this report, which are solely those of the author. 4 ippr | After the Coal Rush: Assessing policy options for coal-fired electricity generation
