Question
What is the amount of energy produced (including distributed production) in Helsinki? Where is it produced (-> emissions)? Which processes are used in its production?
Answer
Rationale
Amount produced is determined largely by the energy balance in Helsinki and Helsinki energy consumption.
Electricity MW | Heat MW | Cooling MW | Fuel | |
---|---|---|---|---|
Hanasaari | 220 | 420 | coal, pellets | |
Vuosaari A&B | 630 | 580 | gas | |
Salmisaari A&B | 160 | 300 | coal, pellets | |
Smaller heat plants around Helsinki | 2200 | gas, oil | ||
Katri Vala | 90 | 60 | cleaned waste water and water returning from district heating network | |
Kymijoki's plants | 60 | water | ||
Powerplant museum in Vanhankaupunki | 0,2 | water | ||
Kellosaari back-up plant | 120 | oil | ||
Suvilahti | Depends in the time of day and year | sun | ||
Total | 1190 | 3590 | 60 |
Heating
Fuel use by heating type
Only district heating is Helsinki specific, rest should be taken from Emission factors for burning processes.
Obs | Heating | Burner | Fuel | Fraction | Description |
---|---|---|---|---|---|
1 | District | Large fluidized bed | Coal | 0.6 | |
2 | District | Large fluidized bed | Gas | 0.4 | |
3 | District | Large fluidized bed | Wood | 0 |
Emission locations
Emission location and height by heating type.
Obs | Heating | Emission_site | Emission_height | Dummy |
---|---|---|---|---|
1 | District | 010 | High | |
2 | Electricity | 010 | High | |
3 | Geothermal | 010 | High | |
4 | Oil | At site of consumption | Ground | |
5 | Wood | At site of consumption | Ground | |
6 | Gas | At site of consumption | Ground | |
7 | Coal | At site of consumption | Ground |
This code creates technical ovariables emissionLocations and heatingShares that are needed to run the Building model and its ovariables buildings and heatingEnergy.
