Waste To Energy

The Waste To Energy technology represents a waste incineration plant. It co-generates electricity and useful heat that can be used directly in the district heating network.

Attribute	Description	Standard value	Unit	Data type
deployment	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.	False	—	bool
kW_el_max	Maximum electrical power output.	inf	kW_el	str/float
force_cap_max	Force implementation of maximum capacity specified in kW_el_max. Only relevant for optimisation.	False	kW	bool
cap_min_use		0	kW	float
annual_msw_supply		inf	kg/year	str
hv_msw_MJpkg	Lower heating value of municipal solid waste (MSW).	12	MJ/kg	float
eta_el	Electrical conversion efficiency.	0.35	—	float
htp_ratio	Heat-to-power (htp) ratio (kW_th/kW_el)	1.5	kW_th/kW_el	float
msw_price_CHFpkg	Price of municipal solid waste. Will usually be negative (i.e. revenue).	-0.3	CHF/kg	float
co2_intensity	Carbon-dioxide intensity of technology output (annual average value).	0.645	kg CO2/kWh	float
lifetime	Expected lifetime of technology before replacement is required.	25	years	int
capital_cost	CAPEX cost of technology per unit of capacity.	2000	CHF/kWp	float
maintenance_cost	OPEX cost of technology per unit of capacity.	119	CHF/kWp/year	float
interest_rate	Interest rate for computing levelised costs (if required).	0.025	—	float

The relationship between the in- and outflows is given by

\[\mathtt{v\_e\_wte} = \mathtt{eta\_el} \cdot \mathtt{u\_msw\_wte}\]

\[\mathtt{v\_h\_wte} = \mathtt{htp\_ratio} \cdot \mathtt{eta\_el} \cdot \mathtt{u\_msw\_wte}\]

The symbols and names of the flows are

u_msw_wte	Inflow Municipal solid waste
v_h_wte	Outflow Heat
v_e_wte	Outflow Electricity
