DEWG / SDAWG Normal report on ERCOT issues: Slight decline in number of issues, most recently centered around Lodestar Upgrade, though no major issues. Followed up on the ERCOT stabilization efforts: Identified projects to watch for in 2009 that address common flaws in the current systems around reports and extracts that need to be maintained until Nodal replacement is implemented. Worked with ERCOT to resolve EILS Settlement Issue: PRR786, submitted to target ERCOT to use the most recent Load Ratio Share (Final Settlement Version) and so a resettlement using the most current load (True-up Settlement Version) Following discussion and review, COPS voted unanimously to recommend support of PRR786 with changes suggested to PRS.
