To endorse and forward the 5/11/11 WMS Report, Impact Analysis and Cost Benefit Analysis for SCR761 to TAC and to recommend a priority of High and a rank of 12.78.
This System Change Request (SCR) requires ERCOT to:
Provide Application Programmatic Interface (API) notification of all republished corrected prices; and
Always publish all price corrections in Extensible Markup Language (XML) format using the same XML Schema Definition (XSD) that it is using for the regular price publication.
Reason:
Presently all price change notifications are through e-mail, which is difficult and time-consuming for Market Participants to manage. Presently, when a price correction e-mail arrives, a Market Participant has to go back to the Market Information System (MIS), manually retrieve the price corrections and manually upload them in the Market Participant’s systems. This is a time consuming task and requires constant monitoring of the ERCOT e-mails.
