Please see issue quintel/etsource#236\r\nI think that issue deals primarily with the 'energy' CHPs which typically have a heat contract. As we are talking about agricultural CHPs (which can't sell their heat nor adjust their efficiency for making electricity), the issue of what their marginal costs should in the electricity merit order is a bit more subtle:\r\n\r\nIf no heat is needed: marginal costs should include fuel costs for both electricity and heat\r\nIf heat is needed:\r\nIf cost for running CHP < cost for running backup heater: marginal costs are zero (this never happens)\r\nIf costs for running CHP > cost for running backup heater: marginal costs are difference between costs for running CHP and running backup heater. This can likely be approximated well by setting the marginal costs to exclude the heat production part (as proposed in quintel/etsource#236).\r\n@AlexanderWirtz does this make sense to you as well?"}}
