Actual solar generation time series for Spain 2015 has non-zero loads for every hour of the year

[redekok]

For the actual solar generation time series for Spain 2015 (ES_solar_generation_actual, hourly based time series, from 2015-01-01 to 2015-12-31) there are non-zero loads for every hour of the year. I would expect the loads to be zero between sunset and sunrise.

I would be very interested in finding out why this is the case.

That is concentrated solar power (CSP).

Thanks @jgmill! Just to be sure: there is probably no way to get the separated time series for solar PV on the one hand and CSP on the other hand (through the OPSD or through any other platform)?

[jgmill]

Yes there are! I just found the very comprehensive ESIOS data portal from Spanish TSO REE. If you go the Generation and Consumption section, scroll down to "MORE" and type "solar". You will find Real time generation and Measured generation for solar PV and thermal separately.

Measured generation seems to have publication lag of one month, potentially making it more accurate than Real time generation. Note that data from ENTSO-E Transparency that we use for OPSD is real time data.

Thanks a lot!

Although the issue has yet been closed, I'd like to ask a brief follow-up question.

When I looked at the solar PV profile for 2015, I noticed there are still non-zero loads for every hour of the year, although the nightly values do approach values very close to zero. Could this still be due to some residual production? Or would this have to do with some (minor) measurement errors? 🤔

Ah, I did not expect that, Is that real time or the measured generation? In any case, I don't know what explains this. You would have to inquire directly with REE.

[redekok]

It's the measured generation. Thanks, I'll ask the REE!
