3 The Investment Programme MaxBio totals 5,25 billion DKK (DKK bn) Objectives To ensure maximum profitability of the existing generation assets during the investment period and to prepare for the continued implementation of Vision 23 To profitably use the maximum amount of biomass for combined heat and power generation in the existing generation assets Investment Programme split up Included in the Investment Programme All maintenance investments and mandatory investments during the investment period All investments for renovation and expansion The present Investment Plan including: renovation of NJV2 life extension programme (1 years) for AMV3 life extension programme (1 years) for FYV7 additional electricity generating capacity (MP-turbine) for AMV1 All investments required to increase the use of biomass in co-firing with coal Not included in the Investment Programme AMV1 AMV3 FYV7 FYV8 NJV2 NJV3 Maintenance investments Total Carbon Capture and Storage-project at NJV3 New Biomass plant at Hillerød/Helsingør Development projects, e.g. District Cooling, Energy from Waste etc 3

4 Major activities in MaxBio per site AMV1 Abstract Amagerværket MP turbine increasing the net output from 71/25 MWe/MJ/s to 113/215 MWe/MJ/s 1% use of wood pellets (from 4%) replacing 17. tonnes of coal AMV3 life time extension 1 years to 228 co-firing of wood pellets (max 4%) replacing 19. tonnes of coal AMV total annual reduction of CO2: 8. tonnes in average (4 +4 ) Abstract Fynsværket FYV7 life time extension 1 years to 23 co-firing of straw (max 15%) replacing 78. tonnes of coal, FYV8 improved biomass flexibility FYV total annual reduction of CO2: 17. tonnes in average (17 +) Note: FYV8 neutral since one type of biomass is replaced by another NJV2 Abstract Nordjyllandsværket replacement of I&C replacement of sulphur removal system NJV3 co-firing of wood (max 4%) replacing 286. tonnes of coal NJV total annual reduction of CO2: 6. tonnes in average (+6 ) Note: NJV2 no reduction of CO2 since it operates as a peak-load plant on coal 4

5 The Investment Programme MaxBio increases electricity production and decreases CO2 emissions per kwh 1. Dry year Electricity production (electricity production GWh) Wet year (CO2 kg/kwh) 1,9,8,7,6,5,4,3,2 CO2 emissions per kwh CO2 emissions ( from coal and gas) (tonnes CO2) , CCS on NJV3 PT portfolio pre programme PT portfolio post programme PT portfolio post programme including CCS on NJV3 5

6 CCS på NJV Full scale anlæg på NJV3 færdig 213 Kul er et nødvendigt brændsel I mange år endnu Vattenfall skubber til teknologien Nu: Dårlig økonomi Fremtid: En lav CO2 fjernelses pris pga. bedre teknologier med lavere energi forbrug Sker kun ved tæt samarbejde mellem leverandører og energi industrien => security of demand (EU arbejder på finansiering af 12 demonstrationsanlæg) 6

7 Største udfordringer Tilgængelighed af bio brændsler Verdensmarkedet pt er max 1 mio tons træpiller (Vattenfall vil skulle bruge 2,5 mio ton træpiller ved 1% substitution) England og Holland bruger allerede en del træpiller og forbruget forventes ikke at blive reduceret. Priser på bio brændsler Kan leverandørerne følge med? Logistik + lagerforhold Energiindholdet per kg i træpiller er ca 7% af hvad det er for kul. For flis er det ca 4%. Fylder meget Flere skibsstransporter ekstra kaj og losse kapacitet Indendørs lagring Investeringssikkerhed Værdi af CO2 Afgifts systemet Ingen lovhjemmel for CCS endnu Lagring af CO2 CCS på bio fyrede anlæg 7
