IEA International Combined Heat and Power (CHP)/District Heating and Cooling (DHC)
In the G8 Gleneagles Communiqué of July 2005, G8 leaders stated that "IEA will advise on alternative energy scenarios and strategies aimed at a clean, clever and competitive energy future". In Heiligendamm in 2007, these leaders issued a direct charge that nations must increase their use of Combined Heat and Power (CHP).
The IEA International Combined Heat and Power (CHP)/District Heating and Cooling (DHC) Collaborative is designed to help evaluate global lessons learned and guide the G8 and other efforts. The CHP/DHC Collaborative assesses global markets and policies for these important technologies. It is also producing data on current installations, assessing technology growth potentials for key markets, and documenting best practice policies - offering insights to policymakers and industry seeking to advance these low-carbon solutions.
Data on existing global CHP capacity in over 40 countries has been collected in order to lend insight into how CHP has faired globally, while also highlighting those countries with particularly successful experiences. CHP potential modelling has been performed in order to give policy makers a sense of what is possible with additional policy support, while the benefits analysis shows how the additional CHP capacity would impact capital investment costs, delivered electricity costs, CO2 emissions and fuel consumption. To aid in analysing different national markets, policies and approaches, the IEA plans to develop a series of CHP/DHC Country Scorecards in 2008-09 for key countries.
