Outage Scheduler 4.9.2 Testing: Testing Window
• QSEs and TSPs are required to sign up via email for a
testing window
– This will initiate a number of events that will occur before the
Testing Window (detailed in a later slide)
– Testing Window includes:
•
•
•
•
2 hour support and scripted testing call
Resolution of issues during the 2 hour support call
7 calendar days testing window for prioritized support and self guided testing
Optional self guided testing are test scenarios that the QSEs and TSPs have
defined and execute independently in the EDS environment
– Scheduling your testing window early allows more time for self
guided testing, make-up windows and issue resolution

Outage Scheduler 4.9.2 Testing: Basic Communications Test (“Ping” Test)
•
MPs testing on the Web Services for the first time will be Scheduled for a
1 Hour Basic Communications test

– 1 hour is allocated to address any issues
– Tests performed on the call will be as follows:
• ERCOT performs a telnet to QSEs and TSPs Listener
• QSEs and TSPs performs telnet to ERCOT External Web Services Listener
• QSEs and TSPs send a sample transaction to ERCOT External Web Services Listener
•
Prior to this test MPs using External Web Services will need to have their
network and security teams make the following changes:
– QSE and TSP Listener must be on port 443 using one of the following
Certificate Authorities

– This certificate will also work in the Nodal Sandbox environment
– It will not work in production, MOTE, or any other ERCOT
environment
– The Digital Certificate will be sent to the MP USA
• Distribution will occur after the MP signs up for a Testing Window
and Just Prior to the Support Call
– (for those requiring the basic communications test, it will be sent
prior to that session)
• All valid ERCOT issued digital certificates will continue to work in
the Nodal Sandbox
