  3. NPRR 503 • Would eliminate Report/Statistics on “Planned vs. Actual” Outages • ERCOT has report defined & running in background—will forward input assumptions to group— • ERCOT suggested SCR as way to add useful info to Outage Scheduler—for example—adding report of completed outages rather than letting them roll off immediately when end date entered, adding box for additional info on why cancelled/if moved, etc. • CMWG will work to suggest potential modifications to OS Info and further explore potential for “one off” email communication through ERCOT about outages of “significance” at April meeting
