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
Retail/Commercial systems
– 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

• Recovery Priority
- Retail Services will normally be restored, or failed over, in a
parallel fashion
- Should prioritization be necessary, the following order will be
followed

Retail/Commercial Systems – DR Capability
• 6 hour RTO would require additional costs
– ERCOT would need to undertake a formal initiative to determine the
scope of necessary changes/costs
