Retail/Commercial Systems – DR Capability
• Capable of operating out of the primary or alternate data center
• Capable of a 0 data loss Recovery Point Objective (RPO)
• Recovery Time Objective (RTO)
– Moving operations to ERCOT’s alternate data center
– ERCOT has historically committed to a 24 hour RTO of all

– After a review of the current DR plan and processes, ERCOT will
commit to a 12 hour RTO
• Assumptions:
– ERCOT’s alternate, or passive, data center is fully functional
– The 12 hour RTO window starts with ERCOT’s first detection of an
issue or incident that may require moving to the alternate data
center
• ERCOT will execute 1 – 2 planned site failovers in the fall/winter of
2014
