Fix interconnector query #3006

Closed KoenvanB closed 2 months ago

KoenvanB commented 5 months ago

This PR adds interconnectors 7-12 to the costs_carriers_electricity_future query.

Discussion Should the ETM use the domestic electricity price for exporting electricity, rather than the weighted carrier costs?

According to the documentation the ETM only takes into account the primary carrier costs when exporting electricity:

For export the ETM charges the costs of the primary carrier that is needed for that export. The export of electricity and transit of oil is cost neutral and independent of the market price. A country does not "earn" money from processing oil. And for electricity the ETM deducts the costs of the primary carriers needed to produce that electricity.

Consequently, however, the import costs are calculated on an hourly basis whereas the export costs are aggregated on an annual basis.

The difference between using the hourly market price (marginal costs curve) and the weighted carrier costs is significant; see this example.

Closes #2991 .

@KoenvanB, thanks for reminding me of this PR. We should definitely merge this commit and I will do so. However, this does not close #2991 since it does not conclude the debate on whether or not to use the hourly or yearly electricity price for export.
