1 Managing Director Marc Roar Hintze Mail: Assens Fjernvarme

2 About Assens Fjernvarme. Placed in the middle of Denmark on the isle of Funen One of Denmark's first and largest decentralized biomass CHP s. Offers the 15 th. lowest heating prices in Denmark CO 2 Neutral due Biomass ton wood chips & ton pellets 3300 district heating customers Heat production MWh Power generation MWh

3 History 1961: Assens Fjernvarme is Founded as a Oil-fired heating plant Cooperative; i.e. non-profit & non-taxed community owned by the people who use its services 1984: New Coal-fired heating plant. Period mainly driven by: Technology, comfort, economy

4 History 1988: Conversion from Coal to Woodpellets and -Chips 1999: Woodchip-fired Combined Heat & Power plant (CHP). 2008: Integration of electric power regulation plant 2017: Integration of windturbine Period mainly driven by: Environment/politics, technology, expansion & economy of scale

5 Drivers in the Danish DH sector ESTABLISHMENT. - Comfort - Technology - Economy DEVELOPMENT. - Environmental policy - Energy policy - Technology CONSOLIDATION. - Large-scale operation - Environmental policy - Climate policy - Energy policy - Sustainable Energy paradigm shift - Bilateral security of supply

6 Biomass Fired CHP Plant

7 CHP Plant design data Energy input 17,3 MW Max Steam production 21,2 t/h Electric output 4,7 MW Thermal output, net excl. exhaust condenser 10,3 MW Thermal output, net incl. exhaust condenser 13,8 MW Steam temperature, turbine 525 C Steam pressure, turbine 77 bar Forward flow DH temperature C Return DH temperature C Heat production MWh Power generation MWh

8 Economy CHP Investment in 1999: ~ /MW electricity Marginal heat Price*: CHP excl exhaust condensator 7,4 /MWh heat Exhaust condensator 6,4 /MWh heat Dry wood chips (blok 1) 26,5 /MWh heat Wood pellets (blok 1) 26,8 /MWh heat Oil (emergency plant) 143,9 /MWh heat * excl. Staff wages, maintenance, depreciation, administration etc

9 Value Creation What is value? Relation between cost and benefits VVVVVVVVVV = BBeeeeeeeeeeeeee CCCCCCCC

10 Value Creation To add value = Provide benefits & Reduce costs in the value chain From forrest to plant: ~23,50-27,00 /MWh From plant to Customer: ~23,50-40,00 /MWh Total ~47,00-67,00 /MWh

11 What is important to the next generation Safety of Supply 100% supply and availability Leakdetection Price/cost Competitive prices Price stability Intelligent solutions Service Data from heatmeters No trouble inhouse installations Intelligent solutions Notifications from the energyprovider Environment Sustainable & renewable solutions Effective solutions Symbiosis philosophy

12 And now factory tour.

13 Smart metering and High solution data

14 Smart metering Until year 2015: Half yearly drive-by readings For billing only Project target: Optimization of operation Troubleshooting. Reduce Water- & heat loss Temperature optimization Optimization of administration Monthly accounting and follow up on budget Daily operation, mowers & closing procedure Customer service Quality management and communication

15 Smart meters The tools: Kamstrup Wireless M-Bus meters Automatic sampling of data on hourly basis 2x Maxisites (E-forsyning) (READy netværksaflæsning) (Heat Intelligence) ((Termis))

16 DFF-EDB E-forsyning. Web-based self-service portal showing consumption, temperature and economy. Available for all customers Graphs shows MWh consumption or m³ per day, month or year. Graphs shows development in flow and return temperature as well as cooling per day, month or year.

17 Kamstrup READy Web based portal with consumption information, temperature set. Consumption Analysis Tool Available to Employees Operation optimization, maintenance and quality management Data can be retrieved into 2-3 minute values

18 Kamstrup Heat Intelligence Newly developed analysis tool based on GIS and metering data Visualizes actual loads and capacity at building and pipesystem level Identifies possible heat loss as well as critical areas

19 Kamstrup Heat Intelligence If a measured temperature is lower than expected, it may be due to defective pipe or poor pipe insulation If a measured temperature is higher than expected, it may be due to a leak or shortcut circulation.

20 Conclusion Data creates value for utilities and customers Better opportunity to identify errors All shortcut circuits are closed The flow temperature is lowered from 72 to 67 C Reduced heat loss in the entire grid Customer service and satisfaction seems improved Management Service Improved (Movers & Shutters) Customer installations are continuously improved Budgetary follow-up procedure improved Greater knowledge and basis for decision making Optimization of construction costs? Employee resources are not reduced, but create more value

21 Thank you for listening.
