District Heating

Attribute	Unit	Data type	Description
deployment	–	bool	If set to ‘true’, the technology will be considered in the energy system model (this does not necessarily mean it will be used). Only relevant for optimisation.
demand_share_type		str
demand_share_val		float
import_kW_th_max	kW	float	Maximum thermal capacity of heat import (from outside the municipality).
grid_kW_th_max	kW	float	Maximum thermal capacity of the grid.
investment_dh_grid_per_m	CHF/m	int
maintenance_cost_dh_grid_per_m	CHF/m/year	int
closeness_based_dh_expansio_cost		bool
capex	CHF/kW	float
maintenance_cost	CHF/kW/year	float
tariff_CHFpkWh	CHF/kWh	float	Tariff for imported heat.
co2_intensity	kg CO2/kWh	float	Carbon-dioxide intensity of technology output (annual average value).
lifetime	years	int	Expected lifetime of technology before replacement is required.
interest_rate	–	float	Interest rate for computing levelised costs (if required).
