Real-Time Market Energy Bid (REB)
Info
To be removed with NPRR1188 Implementation. NPRR1188 renames the
RTMEnergyBid element to EnergyBidCurve so that it can be used in both
the Real-Time Market and the Day-Ahead Market; the element content is
unchanged. See Energy Bid Curve (EBC). The tabs
below show both forms.
The following diagram describes the structure of a Real-Time Market Energy Bid:

The PriceCurve structure is identical to the structure described in the Services Organization section. On submission, the following table describes the items used for an RTMEnergyBid:
| Element | Req? | Datatype | Description | Values |
|---|---|---|---|---|
| startTime | K | dateTime | Start time for bid | Valid start hour boundary for trade date |
| endTime | K | dateTime | End time for bid | Valid end hour boundary for trade date |
| externalId | N | string | External ID | QSE supplied |
| expirationTime | Y | dateTime | Time of bid expiration | Valid time during the trade date |
| resource | K | string | Resource | Valid resource name |
| PriceCurve/startTime | Y | dateTime | Start time for curve | Valid hour boundary |
| PriceCurve/endTime | Y | dateTime | End time for curve | Valid hour boundary |
| PriceCurve/CurveData/xvalue | Y | float | Megawatts | Quantity in MW |
| PriceCurve/CurveData/y1value | Y | float | Price in \$/MWh | \$/MWh |
