LONG DESCRIPTION:  ERCOT has posted the Operational System Change Schedule for 2010. This schedule lists the cut-off dates for Generation, Transmission and Telemetry Points to be included in each scheduled database load. A cut-off date represents the last date by which network topology or telemetry changes are to be submitted to ERCOT in order to be included in the next scheduled Energy and Market Management System (EMMS) database load. The posted dates are subject to change, as deemed necessary by ERCOT, due to market or ERCOT staff constraints or the Nodal Market transition.
