LONG DESCRIPTION:
For twenty-four (24) hours next week, command and control of the ERCOT system
will be managed by Nodal systems. This 24-Hour Test window will begin on one of
the following days:
Support is expected
from QSEs with Resources starting at 08:00 on the day of the test through the
completion of the 24-Hour test. In addition, support is expected during normal
business hours (08:00 to 17:00) during all other business days during the week
of the test until the test is completed.
A Market Notice will
be sent two (2) business days prior to each test day to announce if that day
has been targeted to conduct the test. An additional Notice will be sent on the
day of the test three (3) hours prior to test start time.
In summary, ERCOT will switch over QSEs with Resources from
Zonal frequency and Balancing Energy dispatch to Nodal frequency and Nodal
Real-Time Markets to control the grid, noting that all settlements will be done
through the Zonal systems. After the test window has been completed, Zonal
systems will resume control. All control and switchover activities will be
administered by ERCOT System Operators and announced as appropriate throughout
the test period via hotline calls and Verbal Dispatch Instructions (VDIs).
Details of the test have been discussed on the Nodal Friday
Real-Time Market calls as well as in the July 23, 2010, 24-Hour LFC Workshop.
