LONG DESCRIPTION:
For five (5) hours next week, command and control of the ERCOT system will be
managed by Nodal systems. This 5-Hour Test window will occur on one of the
following days:
·
July 21, between 11:00 and 16:00
·
July 22, between 11:00 and 16:00
Support is expected from QSEs
with Resources starting at 08:00 on the day of the test through the completion
of the 5-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 9, 2010, 5-Hour LFC Workshop.
