Clean up small and generation only US zones #4173

Open pierresegonne opened 2 years ago

pierresegonne commented 2 years ago

Description

As explained in https://github.com/electricitymap/electricitymap-contrib/pull/3817#issuecomment-1050852974, there are multiple small US zones that should be re-arranged or deleted.

Some of the US zones were too small to show on the map, so to stay consistent, we should remove them from the config altogether.

Others are generation only zones that feed into larger zones. The parsers for these should be merged with those where they feed in.

For details see ⬇️ (@KabelWlan first comment)

I don't exactly know how to provide a clearer list than the following:

The following changes are quite simple:

The following changes are more complicated. US-NW-GRID wind generation is only transmitted to US-SW-PNM. This could be included easily. However it's not clear where solar, coal and gas really go, either to US-SW-SRP or US-NW-BPAT. It's also not clear where US-CAR-SEPA and US-CAR-YAD generation is going to.

For the unclear zones: we either delete them because they're too small or we leave them as they are right now.

If this is not clear enough, just tell me what's missing.

Hey @KabelWlan FYI the TODO was for me not, not really because your overview was not clear 😅. It is very clear thanks, I've updated the issue description.

Will be done through #4741 by adding the producing zones directly in the parser to the supplying zones. For the unclear zones we leave as it is for now.

US-NW-GRID which transmits wind generation to US-SW-PNM only might be one to be added as well as long as you're okay with splitting up zones because it's not clear where solar, coal and gas really is sent to.

@KabelWlan just a small follow up on US-NW-NWMT. Do you know where I could find info about the power supply of US-NW-NWMT by US-NW-GWA and US-NW-NWA?

KabelWlan commented 1 year ago

Hi @unitrium I hope the following explanation makes things clearer.

Both US-NW-GWA and US-NW-WWA are "generation only" zones. EIA describes them as the following: "Generation-only balancing authorities do not serve any internal demand and export all of their generation to neighboring balancing authorities" (this is cited from the info-icon on the EIA-Grid monitor map). Unbenannt

As you can see here for US-NW-GWA interconnection, they send all their produced power to US-NW-NWMT (same applies to US-NW-WWA). NWMT serves internal demand, as it is a "normal" zone. Unbenannt1

Thanks the clarification!

I'm revisiting this thread a bit because US-SE-SEPA has been a bit annoying lately: image It's a zone we often can't flowtrace because it has no exchanges and it's production is 0. Would be great if we could figure out where the electricity flows.

unitrium commented 5 months ago

Quickly looking at the EIA exchanges it sends electricity to DUK, SC, SOCO, SCEG. So it might be tricky to figure out who is getting the electricity.

Maybe for this one the solution is to hide it on the map or mark it as generation only so that it's clear there's no customers. Maybe @Alportan you might want to integrate this in your US brief ?
