El Salvador electricity source update #5233

Open pnook opened 1 year ago

pnook commented 1 year ago

Hi, El Salvador grid, https://www.ut.com.sv/home , has real time data for electricity production, https://www.graficostr.ut.com.sv/ . It seems Electricitymaps is interpreting that all Thermal generation as 100% oil. But thermal generation should be split into natural gas (LNG) AND oil. Right now, all thermal generation is natural gas, so carbon intensity value is less than Electricitymaps is calculating.

We are using https://estadistico.ut.com.sv/OperacionDiaria.aspx as the current source and it don't split up thermal by source. And based on the historical data when the parser was created mapping it to oil was the decision taken at the time.

This new source does split things up further by having a separate value for natural gas and thermal as well as solar. So I'll look into if it's possible to create a parser for this new source in a simple way so we get the correct values going forward.

Is a parser buildable?

VIKTORVAV99 commented 11 months ago

The required data is there but it's on a grafana dashboard so it's very hard to extract it. But if you want to give it a try feel free to do so.

I can try to figure out how to extract from grafana dashboard.

Scratching my head on this for a while. Where is the breakdown of thermal (Térmicos) in natural gas vs oil?

In the table in your screen shot I suppose "Térmicos" = oil (both bunker oil and diesel) and "Gas natural" = gas. This split is also visible on National Energy Council's Statistics monthly split, https://estadisticas.cne.gob.sv . Based on that statistic, El Salvador got electricity production from natural gas in March 2022.

FYI, it is possible to get historical data for approximately the last 3 quarters by editing from and to parameters into the URL of the iframes embedded in the dasboard, e.g.: https://www.graficostr.ut.com.sv/grafana/d-solo/000000001/sitio-web-general-1?refresh=5m&orgId=1&panelId=11&from=1601000067367&to=1706028367368

I also noticed https://www.ut.com.sv/home has price data: (use the blue < or > to view)
