  10. WMS Update Eric Goff, Chair of WMS presented the Update 4th Quarter 2010 Emerging Technologies Implementation Plan (ETIP) (Vote) approved Consider Recommending Resettlement or Giving Further Direction to WMS for System Lambda Pricing of Dead Buses (Vote)- No action taken.ERCOT discussed variation of dead bus issue about the split bus. In DA, entity purchases PTP obligation on the right side to left side of bus (both breakers are closed), then they will clear at zero. Then in real time and unit is not running (then breaker is open) so ERCOT utilizes one of the 3 rules which creates a different spread between the right and left hand side of the bus. Entity makes money off that spread. ERCOT says there is huge activity. ERCOT does not see a short term fix on this.
