3 Energy saving technology is already here! and has been so for several years. District Heating & Cooling (DHC) offers the energy efficiency and supply stability which is demanded now and will be in the future. As a multi-fuel system, DHC can extract the best from any source of energy including those of the future. Date 3

12 District Energy The Concept Any energy The idea of district energy is to have an efficient and often large-scale production of heating or source, cooling in a centralized plant. renewable, present or Most times the heating or cooling is co-generated with electrical power, which yields a very high efficiency future, utilisation of the energy input. can be used in the District Energy system! The district energy system is unique in the way that it lends itself to an endless range of fuels it is in other words a multifuel energy system. Date 12

13 District Energy - Centralised Community Heating Plant as the Core Traditional Power Plant 60% of energy wasted as heat to the environment Fuel input = 100% Typical: Oil, Gas and Coal 40% energy output as electricity New combined Heat & Power plant 10% of energy wasted as heat to the environment Fuel input = 100% Typical: Natural gas, waste and biomass 40% energy output as electricity 50% energy produced for heating and/or cooling distributed by district energy system Date 13

14 The RES Directive by EU In Spring 2007 EU decided on it s 20x20x20 in 2020: 20 percent increase in energy intensity (efficiency) 20 percent reduction of CO2 20 percent renewable energy Achieving this ambition will at least cost EURO 100 bn (Barroso) EURO 155 per year per European citizen. UK: 9 bn. per year (open Europe). The Climate and Energy Package contains the Directive on Renewable Energy Sources (RES) outlining how to achieve 20 percent renewable energy. District heating and heat pumps play significant roles in the RES Directive. Date 14

15 The implementation process EU National Responsibility Fall 2009 June 30, 2010 EU Directive National Implementation National Enforcement X legislatory instruments! financial instruments information instruments District Heating & Cooling is now accepted as being a vital part of the future energy supply!

21 The prospects for District Heating & Cooling District Heating and Cooling has been around for decades. The principle of central production of energy is nevertheless just as relevant now and in the future due to the high effectiveness, low pollution and supply stability in a DHC system. There are multiple examples of the energy saving effects of effective District Heating and Cooling systems. When combined with renewable energy sources, DHC becomes a very powerful energy system. By the RES directive, the important position of DHC in the future could not be stated any clearer. Date 21
