1 e-Tag 1.8 An industry tutorial

2 e-Tag 1.8 The basics features of e-Tag 1.8 are much the same as in the current version The tag author uses Agent Service to create and submit requests Authority Service validates requests and manages approval process Approval Services are used by various entities to assess, approve, and submit changes

3 e-Tag 1.8 Requests are a basic of e-Tag There are new tag requests – the initial submittal of a Request for Interchange. Once fully approved, it becomes the e-Tag. There change requests – a market adjustment and a reliability curtailment are two examples of change requests

4 e-Tag 1.8 Requests have status assigned by the authority service to describe its overall state

5 e-Tag Pending Implemented Dead Pending Approved Withdrawn Denied Expired Request states

6 e-Tag 1.8 Almost every request requires assessment and response from approval entities Each approval entitys response is assigned an approval state

7 e-Tag NA Pending Approved Denied Study NA Pending Approved Denied Study Expired Individual Approval States

8 e-Tag 1.8 The composite state indicates the overall state of the e-Tag

9 e-Tag Pending Implemented Dead Pending Confirmed Implemented Cancelled Terminated Withdrawn Denied Expired Composite States

10 e-Tag 1.8 Formalization of the Time Classification schema element Authority Service assigns based on the relative start and submittal times On-time LATE ATF

11 e-Tag 1.8 Improved loss calculations for curtailments In the Authority Service recalculated in-kind losses for a curtailment from the source BA to the sink BA, regardless of the curtailed segment In 1.8 the curtailing entity will specify the segment with the restriction and the Authority Service will recalculate losses both up-stream and down stream of that segment

12 e-Tag 1.8 In … ~ 100 MWs1 MWs2 MWs95 MWs2 MWs Third segment has a 50 MW restriction, Authority recalculates: ~ 50 MWs0 MWs1 MWs48 MWs1 MWs

13 e-Tag 1.8 In 1.8… ~ 100 MWs1 MWs2 MWs95 MWs2 MWs Third segment has a 50 MW restriction, Authority recalculates: ~ 51 MWs0 MWs1 MWs49 MWs1 MWs

14 e-Tag 1.8 Carbon Copy Field In 1.8 the Tag Author may specify other BAs, TSPs, or PSEs who need to know about the transaction but who are not listed in either the market or physical paths in the e-Tag. Carbon Copy entities do not have approval rights

15 e-Tag 1.8 Terminating ATF e-Tags In , ATF e-Tags could not be Terminated if a mistake was made In 1.8 an ATF e-Tag can be Terminated

16 e-Tag 1.8 Dynamic Adjustments E-Tag 1.8 will allow the Source and Sink BAs to submit an adjustment to a Dynamic type e-Tag This is in addition to the e-Tag Author

17 e-Tag 1.8 Energy and Transmission Profiles The Agent and Authority Services will require the e-Tags transmission allocation profile to be > the energy profile

18 e-Tag 1.8 A new ATF e-Tag is restricted to a duration of one hour, except for e- Tag transaction type DYNAMIC. A DYNAMIC type ATF e-Tag may be submitted with a start time up to 168 hours in the past.

19 e-Tag 1.8 Currently, Dynamic type e-Tags can only be adjusted up to 96 hours in the past. Under 1.8, this capability has been extended to 168 hours – again just for Dynamic type e-Tags.

20 e-Tag 1.8 Added new transaction type Pseudo Tie Within the context of e-Tag 1.8, this type behaves exactly like Dynamic transaction type (it is just a different label for unique identification purposes). JISWG is not proposing when or where this transaction type should or should not be used. Other systems using e-Tags may need modification to properly account for the Pseudo Tie transaction type.

21 e-Tag 1.8 Scheduling Entity Field NERC Glossary says: An entity responsible for approving and implementing Interchange Schedules. 1.8 may require a single BA in each Scheduling Entity field – very similar to WECC requirements

22 e-Tag 1.8 Ramp Rate is replaced with Ramp Duration Users will no longer see a ramp duration on intermediate interchange scheduled blocks CI Standards specify ramp start and ramp stop times Uses a default ramp duration of zero for reliability adjustments Uses separate straddled default ramps for Western and Eastern Interconnection.

23 e-Tag 1.8 Within e-Tag 1.8, a rounding standard was added to be used in loss calculations. MW values in e-Tag profiles are sometimes integrated into MWh values across schedule intervals. e-Tag profiles that start or stop within schedule intervals may result in fractional MWh values being calculated. These MWh values must be rounded to the nearest whole MWh. ( =.50 up).

24 e-Tag 1.8 Improved Recovery Function Recovery is a mechanism that an Agent or Approval Service can request updates from all Authority Services for any missed requests Vendor displays may vary – user initiated recovery not always available

25 e-Tag 1.8 Added SSL via HTTPS and client certificate requirement based on NAESB PKI standard. The full implementation of this functionality is dependent on implementation of the new Electric Industry Registry. The e-Tag specification allows this functionality to be enabled at the discretion of each company without impacting any other company. The initial rollout will encrypt data sent to the Authority services and allow for the encryption of data sent by all of the Authority services to any entity who has registered a secure URL (i.e. https rather than http). Companies will need to work with their specific vendor as implementation requirements will vary.

26 e-Tag 1.8 The Buy-At-Market capability was removed from 1.8 specifications.

27 e-Tag 1.8 The Rollout Schedule Remote Interoperability Vendor Testing with NERC/NAESB facilitation on August 7 th, 8 th, 13 th, 15 th, 20 th, and 22 th August JISWG meeting 9-5 and 9- noon – finalize tutorial in Vancouver, BC Starting Sept. 7 through Nov. 2, 2007, User Training and Testing - industry participants and vendors may use this time to train their users and modify their back-office software, as necessary, for 1.8 changes

28 e-Tag 1.8 The Rollout Schedule (cont.) September 7, 11, and 25, 2007 Industry Tutorial/Q&A/Information Sharing through three 2-hour conference calls/webcasts September 19-20, 2007 IS meeting in Montreal Oct 3-4, 2007 JISWG meeting in Houston Nov 5-9 Final Interoperability Testing

29 e-Tag 1.8 The Rollout Schedule (cont.) November 14-15, 2007 NERC IS meeting in San Francisco November JISWG meeting in San Francisco December 4, 2007 e-Tag 1.8 Implementation December JISWG meeting in Houston
