NOTICE DATE: August 20, 2021

NOTICE TYPE: M-B072321-02 Education/Training

SHORT DESCRIPTION: 2021 Severe Weather Drill

INTENDED AUDIENCE: QSE's with Resources, Transmission Operators, Transmission Service Providers, and other interested Market Participants

DAYS AFFECTED: September 9, 2021

LONG DESCRIPTION: The annual Severe Weather Drill (the Drill) as required by the ERCOT Nodal Operating Guide, Section 1.5.4, ERCOT Severe Weather Drill, will be conducted on September 9, 2021. All Transmission Operators (TO's) and Qualified Scheduling Entities (QSE's) that represent Generation Resources are required to participate in the Severe Weather Drill.

The simulation will utilize the ERCOT simulator and will be based on a peak summer load case. Each Market Participant will be issued logins and passwords for remote access to the Macomber Map through Citrix utilizing your company’s digital certificate.  The QSE's/TO's access to the Macomber Map will be limited to viewing only their facilities. ERCOT will design the training scenario, including the line outages, station outages, unit outages, and other events that will be built into the simulation. Participants will be given a list of events, including times they will occur, and will be required to respond and follow any operational instructions issued by ERCOT.

The Severe Weather Drill will simulate a Category 3 hurricane between Matagorda and East Matagorda Bay with intensity of the winds will reach 115 MPH during its peak. The simulated storm then weakens to Category 1 once making landfall (times to be determined). The storm path will continue NW towards central Texas before ultimately dropping below tropical depression levels. The Drill will simulate significant flooding and forced outages in the path of the storm during the Drill.

User logins for Macomber Map will only be issued to Market Participants that RSVP by the cutoff date in the table below.

ERCOT will provide desk phone numbers to use to reach the ERCOT operators during the Drill to all Single Points of Contact. Do not call the ERCOT Real-Time control room at any time for Drill questions or communications.
