TenneT has drawn up its Quality and Capacity Plan for the period 2008-2014 and for this purpose required a robust review of trends in decentralised com-bined heat and power (CHP) capacity and utilisation thereof. CE Delft was commissioned to carry out this review on the basis of its own expertise and experience and interviews with a number of relevant players. The results were translated into terms of four scenarios used as standard practice in TenneT�s plans. In these scenarios, growth of CHP capacity ranges from 1,500 MWe to 3,300 MWe between 2008 and 2014. This means total CHP capacity will lag behind the growth rate envisaged by the government. With dedicated addi-tional incentive policy the desired level can be achieved, though, up to a maximum of 7,000 MWe new CHP capacity, but this gives no consideration to cost effectiveness.
