5. Lead from the Front 9/12/2006 FAQs 1.What information will be available on MIS? Any information specified in protocols to be posted to MIS. 2.What about Retail information? Access to all retail information will continue to be available through TML. 3.What will happen to TML? There are currently no plans to disable the TML site. Duplicate data available through MIS may continue to be available through TML to avoid confusion, or may be removed. 4.What about content already on ERCOT.com? ERCOT.com should not be impacted by the Nodal effort. If Nodal protocols state that information should display in MIS, it will remain in the content management system (where it is now) and MIS will reference that content so that it displays in the content area of MIS. ERCOT.com may continue to point to the same content. 5. Is there a plan to transition remaining information from TML? The non-nodal protocols are not as specific as to the data classification and posting frequency. As non-nodal protocols are revised to specify information posting requirements, data classification and frequency, that information will then move to MIS just as it would in a maintenance mode.
