Good afternoon,

 

I have an additional question in regards to the reports Jessica is referring to below. Will the June 2023 wind/solar power forecast monthly reports be posted or already are posted somewhere?

 

I do not see the June reports on any of the meeting page links.

 

Thanks!

Hi WMWG group – hope this email find you well.

 

I am reading the monthly SolarPowerForecastMonthly report and have a question re: “Curtailment”. Feel free to point me to the right person/distro if this is not the right one to ask the question.

I am looking at the HA System-Wide STPPF tab, columns “RT Aggr Solar-Output (MW)”, “Est. Uncurtailed Output (MW)” and “RT Est. Curtailments” and have a question in terms of the methodology:

  1. Is the “RT Aggr Solar-Output (MW)” number consistent with any other sources of reported solar generation?
  2. Does the “RT Aggr Solar-Output (MW)” include any of the non-telemetry based solar such as the SODG projects?
  3. How do you come up with the “Est. Uncurtailed Output (MW)” amount for a historical period, thus the RT Est. Curtailments? Are you aware of any other data sources from ERCOT which also reports solar or wind curtailment?

 

Thanks

Jessica
