[Data Issue]: US-NW-WACM missing exchanges #5249

Open madsnedergaard opened 1 year ago

madsnedergaard commented 1 year ago

When did this happen?

Now

What zones are affected?

US-NW-WACM

What is the problem?

Exports from US-NW-WACM to several bordering BAs, especially US-NW-PACE, as shown on https://www.eia.gov/electricity/gridmonitor/dashboard/electric_overview/balancing_authority/WACM seem to be missing. These do not seem to be depicted on map with power flow arrows, in consumption 24 hour and historical views, etc. This leads to electricity maps overstating WACM consumption by often 1+GW. Probably affects CO2 intensity values in WACM as well.

Can we get these exchanges on the map?

Displaying exchange data for all the US zones would be very cool. There are many zones with huge amounts of imports and exports. WACM only exports ~10-20% of their generation which compared to other zones isn't even that much.

However, all the exchange data on EIA is delayed by two days, so that makes things probably pretty hard for you guys to show it on the map.

As an example here's SRP exporting more than 50% of their generation and the delay is visible too (screenshot taken on the 30th March while data is unavailable beginning on 29th March at 12am). image

As I suspected after KabelWlans comment we already do have this exchange set up and it's working as expected but the data is too old to be shown on the map (above 25 hour delay); the US-NW-PACE->US-NW-WACM exchange had a 79 hour delay when I ran it just now.

Unfortunately there is nothing we can do about that for now as long as we use the EIA data. Some potential solutions would be to find an alternate source, wait for the exchange estimations to be ready.

As a side note I don't think it makes sense to hide the exchanges in the details panels in the app anymore if there is no data the last 24 (25 if we account for the pipeline delay) hours. We should just show a question mark (?) like we do for other (production) sources that are missing. This will indicate to our users that the exchange exist and we are tracking/collecting data for it but that said data is missing for the moment.

? mark for now makes sense as a placeholder. Looking forward to seeing exchange estimations go live sometime.

In the meantime https://www.eia.gov/electricity/gridmonitor/dashboard/electric_overview/balancing_authority/WACM is stuck at 3 days ago. Anybody else seeing this? crossing my fingers that this means some kind of data upgrade to provide faster updates
