7 Examples of products/solutions Electric spot price DH spot price - Comfort level is set by consumer (cost/comfort trade-off) - Potentially 2-10 hours of load can be shifted, depending on heat load and building type

8 Pilot Projects Period: 1: : : Project: Supported by the Danish Energy Authority's Energy Research Programme (EFP2007) Development and Demonstration of Low-Energy District Heating for Low-Energy Buildings, (EUDP2009): CO2-reductions in low energy buildings and communities by implementation of low temperature district heating systems. Demonstration cases in EnergyFlexHouse and Boligforeningen Ringgården. And Full scale demonstration of LTDH in existing buildings, (EUPD2011) Partners:

9 2. Project : The site in Lystrup 41 flats, area of 87m 2 and 110 m 2 Designed to Low Energy Class I Area 2 HE Typically elderly people or young families are living in the flats Heating power 2.2 to 2.6 kw + 0.2kW due to higher room temperature (radiators and floor heating in bathrooms) DHW power 0.5 (3.5 kw) and 32kW Area 1 ST 9 9

10 The site in Lystrup, DK

11 The Energy Balance for Lystrup, DK Delivered energy an DH net: Yearly energy consumption flats: DH net energy loss: Shunt pump energy: 287 MWh/y 238 MWh/y 49 MWh/y 2.5 MWh/y Extrapolated values outside week Main point: 17% distribution energy loss! In case a normal District Heating net was designed, loss would have been 41%. (Temp. 80/40, single pipes class 2 DH pipes, leading to 200MWh/y) In reality the absolute DH net loss is 4 times higher!

12 3. Project : Sønderby, DK Area with 75 single-family houses from : Average heated floor area: ~ 150 m2 District heating consumption: 6-20 MWh/year per house, Floor heating Existing substations with hot water tank Old network: Sub-net owned by the house owners Connected to utility through heat exchanger District heating supply temperature: C Single street* and service pipes** (Pex) Large network heat loss (43%) * λ=0.038 W/mK, without diffusion barrier (measured by DTI) ** λ ~ W/mK, without diffusion barrier (standard technology of that time

13 3. Project : Sønderby Sønderby, Høje Taastrup, Denmark New pipe network, twin pipes, series 2 & 3, λ = W/(mK) 75 low temperature house substations installed in single-family houses New 3-pipe supply connection demonstrated: 80% heat supply to the Sønderby network comes from main return water! C in supply to the network is sufficient Heat loss in the Sønderby network reduced from 43% to 15% (2012)! Concept and Guideline Low temperature concept demonstrated new and existing houses Draft guideline available.

14 Markets for 4DH District Heating is concentrated in 3 main regions, with huge differences in network conditions, thus different potential for 4G Russia China Europe App. 70% DH penetration App. 30% DH penetration App. 15% DH penetration 2-3G networks, with large potential in network renovation (65-75% of district heating fixed assets require replacements) 1) Limited potential for 4G - Central DHW/HE, - no control on building level - constant flow high design temp. 2-3G networks with potential in network renovation Limited potential for 4G - single source DH - no control on building level - constant flow no DHW high design temp. 3G networks, potential in certain countries for development of 4G networks (however more project driven than country driven at the time being) 1) Source: Ministry of Energy of the Russian Federation, 2010

15 Markets for 4DH Europe, is the region with the biggest potential for development of 4G networks - however it is more project driven than country driven DENMARK Mature DH market 62% DH pen. Several 4G projects SWEDEN Mature DH market 48% DH pen. Traditionally high temp. networks Several 4G projects FINLAND Mature DH market 50% DH pen. Traditionally high temp. networks GERMANY DH market 12% DH pen. Several 4G projects AUSTRIA Immature DH market 21% DH pen. Trends in the markets; Low temperature Electronification and connectivity (incl. monitoring) Variable sources for DH (also 2 way DH) Understand DH as a part of the entire energy system Focus on energy efficiency

16 Markets for 4DH Nordic + CER (biomass) Europe

17 Concluding Remarks District Heating has a bright future, next major step is towards 4 th Generation DH This implies that DH has to develop Main issue is to show that its possible The way forward is to do more 4DH related (pilot) projects And to share the vision across the energy sector
