How much of the heat needed should be produced by burning fossil fuels?
Keep in mind what you have already filled in for the sections 'Demand', 'Costs' and 'Goals'. At the bottom of the screen ('Targets met'), you can see how many of your own policy targets you meet with the current heat production mix. If you move your cursor over this indicator, you will see a table with more details.

Combined heat & power
Combined Heat and Power production is quite energy efficient IF the heat is actually used. How much have you built?
numberMicro-CHPThis indicates how many micro-CHP units you have built in the 'Demand' section. Because their electricity production is not centralized, you cannot influence this number in this section. The power generated is shown in the graph on the right as 'gas-fired' power production.Gas CHPThis indicates how many small Combined Heat and Power (CHP) units of ~1 MWth (~1 MWe) you have built in the 'Demand' section. Because their heat production is not centralized, you cannot influence this number in this section. The power generated is shown in the graph on the right as fossil heat production.
More information on units...Central gas CHPThis indicates how many large gas-fired Combined Heat and Power (CHP) units of ~800 MWe you have built. The heat generated is shown in the graph on the right as CHP heat production. The heat is supplied to the central heating grid. You cannot influence this number in this section, because you can build these plants in the 'Electricity' section.
More information on units...Central coal CHPLarge ultra-supercritical pulverized coal-fired plants. This type of plant is identical to the pulverized coal plant used to make electricity, except that it is also used to supply heat to a central heating grid, reducing its electric efficiency.
You cannot change the number of plants here, as they can be built in the 'Electricity' section.
Because the model uses standard size plants, and in reality both smaller and larger plants may exist, the number of plants installed may not be an integer value. -
Fossil-fired heaters
Currently, most heat is generated by burning fossil fuels. How will this change in the future?
numberCentral coal-fired heaterThis determines how much heat is produced by central coal-fired heaters that supply their heat to heat networks. The heat generated is shown in the graph on the right as heat from coal.Central gas-fired heaterThis determines how much heat is produced by central gas-fired heaters that supply their heat to heat networks. The heat generated is shown in the graph on the right as heat from gas.Central waste-fired heaterThis determines how much heat is produced by central waste-fired heaters that supply their heat to heat networks. The heat generated is shown in the graph on the right as heat from waste.Heat network remainderThis sliders shows how many large gas heaters (100 MWth each) the model needs to compensate for lack of heat production for the central heating grid.
If demand for heat from the central heating grid in the 'Households' and 'Buildings' sections is not met by heaters or CHPs, the model automatically builds these gas heaters to provide the necessary capacity.
To get rid of the 'remainder', please build heaters or CHPs in this 'Fossil heat' section or reduce demand from the central heating grid.
More information on units...Decentral optionsGas-fired heaterThis indicates how much heat is produced by gas-fired heaters as a result of your settings in the 'Demand' section. Because their heat production is not centralized, you cannot influence this number in this section. The heat generated is shown in the graph on the right as fossil heat production.Oil-fired heaterThis indicates how much heat is produced by oil-fired heaters as a result of your settings in the 'Demand' section. Because their heat production is not centralized, you cannot influence this number in this section. The heat generated is shown in the graph on the right as fossil heat production.Coal-fired heaterThis indicates how much heat is produced by coal-fired heaters as a result of your settings in the 'Demand' section. Because their heat production is not centralized, you cannot influence this number in this section. The heat generated is shown in the graph on the right as fossil heat production.Gas-fired heat pumpThis indicates how much heat is produced by gas-fired heat pumps as a result of your settings in the 'Demand' section. Because their heat production is not centralized, you cannot influence this number in this section. The heat generated is shown in the graph on the right partly as fossil heat production and partly as ambient heat production.
