M-A052523-02 RESOLVED - ERCOT Client Digital Certificate Expiration of Newly Issued Certificates at Less Than 365 Days
NOTICE DATE: May 25, 2023
NOTICE TYPE: M-A052523-02 Operations
SHORT DESCRIPTION: RESOLVED - ERCOT Client Digital Certificate Expiration of Newly Issued Certificates at Less Than 365 Days
INTENDED AUDIENCE: User Security Administrators (USAs)
DAYS AFFECTED: May 22-26, 2023
LONG DESCRIPTION: As of May 26, 2023, all newly issued ERCOT Client Digital Certificates have a 1- year expiration date. ERCOT worked with the certificate vendor to extend the expiration date of the ERCOT Client Root CAs and the new CAs have been published to ERCOT.com.
ERCOT experienced an issue with Client Digital Certificate issuance where certificates were being issued that expire in less than 365 days due to the ERCOT Client Root CA's expiration date of May 21, 2024. This did not affect the use of the Client Digital Certificate and its access to ERCOT's secure websites, only the length of time that the certificate is valid.
ACTION REQUIRED: ERCOT suggests that Market Participants (MPs) add these new CAs to all browser or API keystores to ensure that new certificates can be used to access ERCOT's secure websites.
MPs can test the functionality of newly issued certificates in the Market Operations Testing Enviornment (MOTE) for APIs using the URLs below.
ADDITIONAL INFORMATION: Existing Client Digital Certificates will continue to function until their expiration or revocation by the USA. Once the new ERCOT Client Root CAs have been issued by the certificate vendor, ERCOT will publish them to ERCOT.com. MPs will need to add these new CAs to all browser or API keystores to ensure that new certificates can be used to access ERCOT's secure websites.
