NOTICE DATE:  September 15, 2011
NOTICE TYPE:  M-A081211-02 SCR
SHORT DESCRIPTION:  Implementation details of SCR764 - Public Access to Select MIS Dashboards - Phase 2
INTENDED AUDIENCE:  ERCOT Market Participants
DAY AFFECTED:  September 26, 2011
LONG DESCRIPTION:  On September 26, 2011, ERCOT will release the Load Forecast vs. Actual dashboard in the second phase of the implementation of System Change Request (SCR) 764, Public Access to Select MIS Dashboards. The final implementation phase of SCR764 will occur by the end of 2011. SCR764 was approved by the ERCOT Board on May 17, 2011, and it adds the following dashboards, which are currently displayed on the Market Information System (MIS), to ERCOT.com (with each planned phase indicated):

*         Real-Time System Conditions - Phase 1

*         Load Forecast vs. Actual - Phase 2

*         SCED Up/Down - Phase 3

*         LMP Contour Map - Phase 3

*         LMP Ticker - Phase 3

The Load Forecast vs. Actual Dashboard has been updated in design and functionality to include hover capability similar to that available on Today's Outlook on ERCOT.com. Hovering over a plot point will allow System Load or Current Day Forecast MW details to be seen. The dashboard will auto-refresh every 60 seconds.

Technical changes to the architectural design were required in order to make the dashboards available to the public without performance impacts. As a result, dashboards that were available on the Markets - Real-Time Market Landing Page and the Grid - Forecasts Landing Page of the MIS will no longer display on those landing pages. The dashboards will remain available from the MIS Applications page.

The Load Forecast vs. Actual dashboard will be located on ERCOT.com in the Grid Information section, on the Current System Conditions page.
ADDITIONAL INFORMATION:  SCR764 and associated documents can be found on the ERCOT website, under Market Rules, at http://www.ercot.com/mktrules/issues/scr/750-774/index.
