NAESB Update Wholesale Electric Quadrant

Network Service on OASIS – The timeline for completion of the recommendation was

extended – expect completion by OASIS subcommittee 4th quarter 2010

Coordination of Transmission Requests Across Transmission Providers

– Recommendation adopted by Executive Committee & sent to OASIS subcommittee

Proposed 3 Step Process • Customer flags the set of requests for service across multiple

systems (“linked group”). • Each Transmission Provider processes the request on its system

the same as it would process any request on its system (“pre-true-up final state”).

• Upon confirmation, the Customer determines the final capacity amount of each request (“true-up”), which must be equal to or less than the capacity offered. The amount of capacity the Customer confirms may vary per transmission system.

data• Propose to move from a stated (fixed) rate to a formula rate

to be updated annually• Propose to have new rates in effect prior to the end of 2010• Holding discussions with our Network Customers prior to

filing the new rate with FERC• Some of rate impacts have been evaluated but because

discussions are ongoing, nothing has been finalized

Create a TSR that Crosses the Fall Change• “Option 1”

– Start TSR in ED 11/07/10 00:00 & End on or after 02:00 in ES on 11/07/10

– OASIS defaults to the correct time zone (Based on Start and Stop Time)

• “Option 2”– Create a profiled TSR that crosses 02:00– OASIS will populate 2 - HE 0200s (one in both ED & ES)

• “Option 3”– Create a 25 hour reservation profile TSR – OASIS will populate 2 - HE 0200s (one in both ED & ES)

Creating a Tag that Crosses the Fall Change– Fall Time Change creates a 25hr day– One Tag or Two Tags

• Suggest Create Two Tags – One in Eastern Daylight Time

» Begin with the hours 0000 through 0200 ED– One in Eastern Standard Time

» Begin with the hours 0100 through 0000 ES– Change the default TZ to ES

» Misc / Misc User Options

– Verify your tags by re-checking them in both ED and ES• Verify Profile Total• Verify Hours with respect to Standard and Daylight

Using Daylight Time Submitting One Tag– To use this option, user must set time to ED

» Misc / Misc User Options – Begin @ 00:00 on 11/07/10 through 01:00 on11/08/10– Enter as a Delayed Tag– Change the default TZ to ES

» Misc / Misc User Options – Reopen Tag

» In Eastern Standard verify the end to be 00:00 on 11/08/10 (Note: Start time will show 23:00 11/06/10 ES)

– Revert your TZ back to ED – Re-open the Delayed Tag in Daylight Saving Time and

verify the hours and Profile are accurate.» In Eastern Daylight Saving verify the end to be 01:00 on 11/08/10 (Note: Start time will show 00:00 11/07/10 ED)

Verify your tags by re-checking them in both ED and ES time

• Verify Profile Total• Verify Hours with respect to Standard and Daylight Time
