1		Unit	Values	Description
2	year	--	YYYY; e.g. '2030'	Year for which to retrieve cost assumptions of ``resources/costs.csv``.
3	version	--	vX.X.X or <user>/<repo>/vX.X.X; e.g. 'v0.5.0'	Version of ``technology-data`` repository to use. If this string is of the form <user>/<repo>/<version> then costs are instead retrieved from ``github.com/<user>/<repo>`` at the <version> tag.
4	social_discountrate	p.u.	float	Social discount rate to compare costs in different investment periods. 0.02 corresponds to a social discount rate of 2%.
5	fill_values	--	float	Default values if not specified for a technology in ``resources/costs.csv``.
6	capital_cost	EUR/MW	Keys should be in the 'technology' column of ``resources/costs.csv``. Values can be any float.	For the given technologies, assumptions about their capital investment costs are set to the corresponding value. Optional; overwrites cost assumptions from ``resources/costs.csv``.
7	marginal_cost	EUR/MWh	Keys should be in the 'technology' column of ``resources/costs.csv``. Values can be any float.	For the given technologies, assumptions about their marginal operating costs are set to the corresponding value. Optional; overwrites cost assumptions from ``resources/costs.csv``.
8	emission_prices			Specify exogenous prices for emission types listed in ``network.carriers`` to marginal costs.
9	-- enable	bool	true or false	Add cost for a carbon-dioxide price configured in ``costs: emission_prices: co2`` to ``marginal_cost`` of generators (other emission types listed in ``network.carriers`` possible as well)
10	-- co2	EUR/t	float	Exogenous price of carbon-dioxide added to the marginal costs of fossil-fuelled generators according to their carbon intensity. Added through the keyword ``Ep`` in the ``{opts}`` wildcard only in the rule :mod:`prepare_network``.
11	-- co2_monthly_price	bool	true or false	Add monthly cost for a carbon-dioxide price based on historical values built by the rule ``build_monthly_prices``
