We are working to “start early” EDS to encourage earlier MP involvement – quality and support expectations must be managed appropriately• During the ERCOT quality control process,

“early” software versions will be used for EDS testing that have not completed ERCOT's full quality control cycle

• EDS Software versions will have known defects and additional defects discovered during EDS that will be incorporated into the internal release management schedule for prioritization and correction.

• Potential for periods of reduced service level due to unexpected circumstances such as server failures.

• These systems will be available to the market for testing the processes required to run SCED, LFC and CRR

• The EDS environment will be upgraded incrementally with new functionality coordinated with the internal release management schedule. Market Participants will be notified in advance of system upgrades and new functionality.

• System availability, quality of LMPs and other data and support responses will improve over time but may not likely meet production standards at the initial start
