DAYS AFFECTED: June 16,

LONG DESCRIPTION: For
eight hours next week, command and control of the ERCOT system will be managed
by Nodal systems. This 8-Hour Test window will occur on one of the following
days:
·
June 17, between 10:00 and 18:00
·
June 18, between 10:00 and 18:00
Support is expected
from QSEs with Resources starting at 07:00 on the day of the test through the
completion of the 8-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.
A Market Notice will
be sent two 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 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, including
the operational scenarios and approximately 6-7 hours of Nodal control, 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 LFC test have been discussed on the Nodal
Friday Real-Time Market calls as well as in the dedicated 8-Hour LFC Workshop.
