6. 3 December 2010 page International Power 6 IPR position on market reform in the UK On the carbon price floor – the priority must be a mechanism that delivers CO 2 reduction at the least extra cost to the sector and the consumer On renewables deployment - overall, it is timely to replace the Renewables Obligation with a Feed-in-Tariff mechanism On low carbon obligation and capacity payments: need to consider the whole market, not just the low carbon producers capacity payments offer a credible mechanism for delivering the attributes needed for a viable electricity system On Emission Performance Standards – in light of existing and new emission reduction regulation, Emission Performance Standards are an unnecessary regulation

8. 3 December 2010 page International Power 8 The industry is faced with a number of major challenges in the coming decade Market reform needs to consider the whole market, in recognising that a number of attributes are needed for a viable and effective system Developments in the UK cannot be in isolation from what is happening in the rest of Europe. IPR is very well placed to contribute to the electricity mix of the future Concluding remarks
