Energy Bid Curve (EBC)

Info

Added with NPRR1188 Implementation. Replaces Real-Time Market Energy Bid (REB).

The EnergyBidCurve replaces the RTMEnergyBid so that it can be used in both the Real-Time Market and the Day-Ahead Market. The element content is unchanged from the RTMEnergyBid; only the element name differs.

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 EnergyBidCurve:

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

The following is an XML example for an EnergyBidCurve:

<BidSet xmlns="http://www.ercot.com/schema/2007-06/nodal/ews">
    <tradingDate>2014-04-01</tradingDate>
    <EnergyBidCurve>
        <startTime>2014-04-01T00:00:00-05:00</startTime>
        <endTime>2014-04-02T00:00:00-05:00</endTime>
        <expirationTime>2014-04-02T00:00:00-05:00</expirationTime>
        <resource>RESOURCE_1</resource>
        <PriceCurve>
            <startTime>2014-04-01T00:00:00-05:00</startTime>
            <endTime>2014-04-02T00:00:00-05:00</endTime>
            <CurveData>
                <xvalue>0</xvalue>
                <y1value>250.00</y1value>
            </CurveData>
            <CurveData>
                <xvalue>10</xvalue>
                <y1value>225.00</y1value>
            </CurveData>
            ...
            <CurveData>
                <xvalue>90</xvalue>
                <y1value>115.00</y1value>
            </CurveData>
        </PriceCurve>
    </EnergyBidCurve>
</BidSet>

And the corresponding response:

<ns2:BidSet xmlns:ns2="http://www.ercot.com/schema/2007-06/nodal/ews">
