Discrepancies between energy balance and energy graph

[lottevanvlimmeren]

During our work for the ENTSOE country database project, @mabijkerk and I have found some discrepancies between the energy balance and the energy graph. Some of these inconsistencies are already being discussed in separate issues. This issue is meant to give an overview of all inconsistencies we have encountered and to discuss additional remarks.

There are two smaller discrepancies that can be fixed easily:

• Due to a copy-paste mistake, some EB products are not included in the final demand for the node transport_final_demand_biodiesel. There is a separate issue concerning this discrepancy: https://github.com/quintel/etsource/issues/2568.
• The flow 'non-specified (transport)' is included in the final demand for non-energetic oil in the ‘Other’ sector. In ETDataset, the total of this flow is added to energetic crude oil. I would suggest to match the energy graph to ETDataset by adjusting the nodes other_final_demand_crude_oil_non_energetic and other_final_demand_crude_oil accordingly.

Besides these two points, we have some other remarks that are not as easy to solve:

• Currently, gasoline is distributed over road and aviation fuels in the energy graph. This is consistent with the gasoline distribution on the Dutch Eurostat energy balance. However, for other European countries gasoline is also used in domestic navigation, in addition to road and aviation. @mabijkerk and I would suggest to add this new energy flow to the energy graph.
• Distribution losses are only considered for heat and electricity in ETLocal, while the losses for crude oil and natural gas are included in ETSource (in energy_distribution_crude_oil_loss and energy_distribution_network_gas_loss). Is it necessary to add these losses to ETLocal?
• The Eurostat flow "fishing" is included in ETDataset in the agriculture analysis. However, the flow is currently not included in any node in the graph. There is an open issue discussing this inconsistency: https://github.com/quintel/etsource/issues/2546 that additionally discusses moving the "fishing" flow from agriculture to the transport sector.

@AlexanderWirtz @michieldenhaan @marliekeverweij we would like to hear your opinion about the aforementioned discrepancies.

Thanks for the overview! Good to know all discrepancies. Here my opinion on two of them:

Currently, gasoline is distributed over road and aviation fuels in the energy graph. This is consistent with the gasoline distribution on the Dutch Eurostat energy balance.

Yes, this is a good idea and should happen IMO. I will add it to our project on BC

Distribution losses are only considered for heat and electricity in ETLocal, while the losses for crude oil and natural gas are included in ETSource (in energy_distribution_crude_oil_loss and energy_distribution_network_gas_loss). Is it necessary to add these losses to ETLocal?

Yes I think so. I will add it to the list of missing ETLocal keys on BC
