• Cost to Serve Load down year over year by $0.58 • Market prices down on average by approximately $15 • Market price volatility down significantly for Q2 2012 compared to 2011• West Zone Prices and West Zone to West HUB congestion activity
continues to be active• Significant increase in prices clearing at $18 or less• Drivers:
– Lower gas prices– Weather impact (4 degrees cooler in 2012 compared to 2011)– West wind activity
Settlement Observations- Summary

• NPRR 347 and NPRR 391 present significant changes to the current settlement and invoicing timeline– NPRR 347 combines DAM and Real Time settlements to a single

and eliminates ACH as a method of payment of invoices• CSWG continues to follow progress of the project at the monthly
meetings with project staff reporting on status and milestones• ERCOT provided at July CSWG meeting a transition plan for the
implementation of these changes
