Agenda  Follow-up to Action Items  OASIS Training  NAESB Update - Wholesale Electric Quadrant  Wrap-up 2

Follow-up to Action Items Items from May 19, 2011 meeting to date  Duke was asked: 1.Provide the limiting element of each posted ATC value on OASIS 2.Consider changing the time that Duke releases unscheduled firm capacity to the non-firm ATC from 10:00 to 09:00 3.Model some fraction (less than100%) of total Firm reservations for DA model 4.Discuss ATC Values for monthly firm ATCs on import paths Requests spurred internal meetings, research & evaluation Our findings will be presented today. 3

Action Item Posting Limiting Elements of ATC Duke was asked to provide the limiting element of each posted ATC value on OASIS  Goal of the request is to provide additional information on ATC limits  At this time, current process will continue  We have created/posted a Flowgate Ownership Table Lists each flowgate #, owner, & name in the AFC process 4

Action Item Release of Unscheduled Firm Duke was asked to consider changing the time that unscheduled firm capacity is released to the non-firm ATC  Goal of the request is to increase the next-day non-firm ATC sooner  Current time is 10:00 EPT  Proposing changing time to 08:00 EPT One year trial period o early termination if reliability problems arise Does not change the firm scheduling deadline (10:00 EPT or as accommodated) Does not change the hourly non-firm timing lead time (12:00 EPT) 5

Action Items Model of Firm reservations for day ahead model Duke was asked to model some fraction (less than 100%) of total firm reservations for day ahead model  Goal of the request is to increase the next-day non-firm ATC sooner  At this time, current modeling will continue Creates reliability concerns Decreases market transparency Goal of creating more non-firm ATC can be accomplished by releasing unscheduled firm capacity to the non-firm market earlier (see previous slide) 6

Action Items Monthly Firm ATCs on Import Paths Duke was asked to investigate why ATC values “jumped around”  There were three months in question September 2011 – Outage related October 2011 – Outage related January 2012 – Limit has been historically seen in operations with the load forecast/gen dispatch in case Also seen in last years area interchange methodology Next-Day Studies 7

OASIS Training Rebid Rebid of Partial Service NAESB WEQ FERC Order 676E requires the Transmission Provider to allow the Transmission Customer to negotiate Price and/or Capacity  Upon TP action to Accept or Counteroffer the Customer is allowed to Rebid Price and/or Capacity  Rebid of Price functionality was on OASIS soon after the Order was issued Duke does not enter into Price negotiations at this time Rebid Price will result an INVALID status  Rebid MW functionality was placed on OASIS just before April 1, 2011 Capacity can be rebid in a lesser amount than the COUNTEROFFER Status changes from COUNTEROFFER to REBID to ACCEPT to CONFIRMED or WITHDRAW follow the time limit as stated in Duke OASIS Business Practice 3.D. 8

OASIS Training Creating Rebid MW Customer Created TSR for 250MW Counteroffer(MW Grant) is 102/200MW  Open TSR Click 9

OASIS Training Creating Rebid MW  Click on  Change the Value in the MW Req  Under New Status Choose REBID Customer Created TSR for 250MW / Counteroffer (MW Grant) is 102/200MW 10

OASIS Training Rebid MW After submitting the REBID MW, the request will be returned with a status of REBID to the Transmission Provider The Transmission Provider will respond by moving the request to DECLINED, SUPERSEDED, ACCEPTED or COUNTEROFFER The Transmission Customer must acknowledge the Providers offer by moving the request to either CONFIRMED or WITHDRAWN (or if need be REBID again) All status changes must be done within the time limits as specified in Duke OASIS Business Practice 3.D. 11

OASIS Training webOASIS – Sys Data Summary ATC Postings The System Data Posting Summary display lists the System Elements that are to be posted to OASIS per the Standards & Communication Protocol version 1.5 (S&CP v1.5) System Data includes:Load ForecastActual Load TTCATC Narratives ATC related information Note: FATC or NFATC as shown on OASIS is updated anytime webTrans calculates a change in the Effective ATC for Firm or Non-Firm. On the OASIS Menu click to view FATC or NFATC System Data Summary UI screen will open Choose the Filter Criteria of interest such as: TP Attribute Element and Time click Enter 12

OASIS Training webOASIS – Sys Data Summary ATC Postings Based on filters from the query: 24hrs of Data is returned The lowest Value is what is available Daily Information found here should match what is posted for Offerings ATC Posting returned through SysData is a good point of reference Transmission Requests can be created from the SysData Summary 13

OASIS Training Create a TSR from SysData Summary ATC Postings Transmission Requests can be created from the SysData Summary 1.Click on Posting Ref 2.Click on 14

OASIS Training webOASIS – Sys Data ATC Portfolio As an alternative Users may access ATC info through Sys Data by use of the ATC Portfolio From the OASIS menu click on to view FATC or NFATC System Data Summary UI screen will pop up Click on the grey button Choose the Filter Criteria of interest such as: TP Increment Element Date click Enter Clicking will reveal a Calendar, for a specific date. 15
