Photovoltaic Generation Resource Production Potential

The purpose of this interface is to provide a query for fetching Photovoltaic Generation Resource Production Potential (PVGRPP) for each Photovoltaic Generation Resource (PVGR) as well as PVGRPP forecast for all PVGRs. This interface will return the last hour data for the requesting hour-end.

The request message would use the following message fields:

Message Element	Value
Header/Verb	get
Header/Noun	PVGRPP
Header/Source	MARKET PARTICIPANT ID
Header/UserID	ID of user
Request/endTime	End time of interest
Request/ID	Optional: PVGR identity If No PVGR is provided, PVGRPP for all PVGRs is returned.

The corresponding response messages would use the following message fields:

Message Element	Value
Header/Verb	reply
Header/Noun	PVGRPP
Header/Source	ERCOT
Reply/ReplyCode	Reply code, success=OK
Reply/Error	Error message, if error encountered
Payload/	PVGRPP
