Open Action Items from Spring 2008 Stakeholder Meeting



5

Open Action ItemsDarrin Adams (EKPC): Has there been any curtailment in relation to these TLRs? (Stuart Goza -TVA)) The only curtailments resulting from these TLRs have been the curtailments of scheduled transmission services. ♦ TLRs are listed at the NERC website at the following link.

(http://www.nerc.com/~filez/Logs/tlrlogs.html). ♦ The website posts the TLRs as called by the RC and not by the Control

Area. ♦ Filter the data by RC (TVA) and then compare it to a list of E.ON flowgates

IDs from their OASIS website. ♦ TLR specific information can be requested from the RC by contacting Stuart

Goza with the date and time of the TLR event. Daryn Barker (E.ON-US): Maybe we can limit the data that is presented to only those elements that limit AFC to zero and include monthly’s also. (Jonathan Hayes – SPP) After reviewing the data that was presented, only those limiting elements that went to zero were included in the data posted.

Open Action ItemsDarrin Adams (EKPC): Has there been any curtailment in relation to these TLRs? TVA suggests that anyone interested in this information can use the following link to search curtailment logs. http://www.nerc.com/~filez/Logs/tlrlogs.htmlDaryn Barker (E.ON-US): Follow up with TVA on the actual process to do this during energy emergency events. TVA is not a party to the CRSG events. The NERC EEA process is defined in NERC Standard EOP-002. See link.ftp://www.nerc.com/pub/sys/all_updl/standards/rs/EOP-002-2.pdf

DNR/NITS Study Process Change

Current Study Process♦ OASIS TSRs are currently being used for DNRs

and Load Additions and are accompanied by NITS Applications sent via e-mail.

♦ These TSRs have service times beyond the 18 month planning horizon.

♦ The TSRs have to be evaluated in the SIS/Long Term Planning Process due to the service time being beyond the 18 month window.

♦ The TSR Queue date is used as the study queue.



23

DNR/NITS Study Process Change Cont.’

Study Process Change♦ OASIS TSRs will still be used for DNRs♦ NITS Applications will be used for Load Additions but do not

have to have an associated TSR.♦ The Study queues will be decided by the following criteria:

The queue date from OASIS on the TSR for DNRsThe received date from the e-mail containing the NITS application for the Load additionsStudy parameters for each study will be decided by the information from both the DNR and Load addition requests at the time of the submission of either the TSR in OASIS for the DNR orof the NITS application for the Load addition.

♦ Propose to start this new processJanuary 1, 2009

ITO’s Assessment of E.ON’s 2007 TEP

2007 TEP based on summer and winter peak models for 2008, 2011, and 2016ITO Assessment Includes:♦ Planning Guidelines♦ Model Validation♦ Powerflow Analysis♦ Operating Guidelines Assessment♦ Planned Project Assessment



373737

Planning Guidelines Review

2007 TEP based on September 2007 revision of planning guidelines♦ ITO validated that 2007 TEP consistently adhered to

the criteria in the planning guidelines and good utility practice

♦ Subsequent revisions of the planning guidelines were also reviewed and the most recent version is posted on OASIS



383838

Model Validation

Accuracy ♦ ITO compared first tier control area generation dispatch

and facility characteristics from E.ON’s models with those included in MMWG models

♦ Reviewed 2007 TEP and ensured that the unit generation simulated in the models is what was expected

Performance♦ E.ON’s generation was verified to be operating within

minimum and maximum operating limits♦ Compared models that included planned projects against

models that did not to ensure projects properly incorporated into the models



3939

Powerflow Analysis

Identified potential thermal and voltage issues in the models

Results analyzed against criteria provided in planning guidelines♦ Thermal issues: Flow above 100 percent of applicable

normal or contingency rating

♦ Voltage issues: Voltage below 94 percent or above 105 percent nominal during normal conditions and below 90 percent and above 105 percent nominal during contingency conditions



4040

Powerflow Analysis Results

3 contingency situations created potential thermal and/or voltage issues affecting 12 monitored elements♦ 2 need projects to be expedited

♦ 1 requires coordination between E.ON and EKPC



4141

Operating Guidelines Assessment

Each operating guideline identified by E.ON as a solution to a violation in the Powerflow Analysis was independently verified.♦ Does it satisfactorily mitigate the violation?

♦ Does it cause issues on neighboring systems?

♦ Does it require coordination with neighboring systems?



4242

Planned Project Assessment

Each project identified by E.ON as solutions to Powerflow violations was independently evaluated.♦ Is it properly modeled?

♦ Is the project adequately timed?

♦ Does the project resolve the violation?



434343

Dynamic Study Assessment

The dynamic models and studies were provided to the ITO in Apr 08.

The ITO reviewed the analysis for adherence to applicable NERC stability standards.

The dynamic study has been included in the ITO’s independent assessment report.



444444

TEP Coordination

RC Coordination♦ TEP presented to TVA as the RC in March 2008♦ RC comments included as part of the ITO’s

independent assessment report

Stakeholder Meeting Presentation♦ Any additional stakeholder questions or concerns

will be considered for the next 30 days♦ Final report will be posted on OASIS by Dec. 31
