12 Sectin 1: Transmissin Operatins Requirements Nte: PJM reviews this manual annually, with peridic updates as required. PJM crdinates identified issues with PJM TOs, PJM GOs and neighbring RCs. As PJM and neighbring Reliability Crdinatrs deem necessary, PJM will facilitate cnference calls that include neighbring Reliability Crdinatrs, neighbring Transmissin Operatrs, neighbring Balancing Authrities, PJM TOs and PJM GOs. PJM will ntify PJM TOs and PJM GOs as necessary regarding issues cmmunicated by neighbring Reliability Crdinatrs. PJM distributes revisins t this manual t neighbring Reliability Crdinatrs, neighbring Transmissin Operatrs, neighbring Balancing Authrities, PJM Transmissin Owners and PJM Generatin Operatrs. Nte: AEP is the registered TOP fr the AEP 138 kv and belw facilities. ITCI is the registered TOP fr its facilities. PJM is the registered TOP fr all ther BES facilities n the AEP transmissin system. Under nrmal perating cnditins AEP will crdinate with PJM t re-dispatch generatin t cntrl flws n their 138 kv and belw mnitred facilities. In an Emergency, AEP will ntify PJM f any unilateral actins it has taken with respect t the re-dispatch f generatin as sn as practicable, but n later than 30 minutes, s that PJM can crdinate with the impacted parties. 1.2 Respnsibilities fr Transmissin Owner's Operating Entity The respnsibilities fr a Transmissin Owner's perating entity within PJM that are defined belw are required t maintain the safe and reliable peratin f the transmissin system within PJM. Transmissin Owners perate and maintain the transmissin system and are respnsible fr lcal reliability. The transmissin Owner under PJM s directin takes all actins required t mitigate transmissin system reliability emergencies. The respnsibilities identified belw are cnsistent with the NERC Functinal Mdel fr intercnnected system peratin. This list is a cllectin f significant peratinal respnsibilities and bligatins f a Transmissin Owner that are included in the PJM TOA and the PJM manuals. It is nt intended t be an all-inclusive list f every respnsibility and bligatin f a Transmissin Owner. Subject t cde f cnduct.

The Transmissin Owner shall ntify PJM (verbally and via edart) f any knwn single cntingency cnditins that results in the lss f multiple generatin units r any cnditin that prevent a generatin unit t start-up after a trip. PJM will review the cnditin and will update the EMS active cntingency set accrdingly. The resultant cntingency culd be the largest MW lst in PJM and may result in additinal synchrnized reserve requirement (BAL-002-2). The Transmissin Owner shall maintain a cntinuusly staffed transmissin cntrl center. The cntrl center shuld meet all f the cmmunicatin and infrmatin system requirements defined in the PJM manuals (Sectin 2 f PJM Manual 01: Cntrl Center and Data Exchange Requirements). Nte: Under circumstances where the Transmissin Owner r Generatr Operatr cannt fllw the directive f PJM (such actin wuld result in safety vilatin, damage equipment, r vilate regulatry r statutry requirements), they shall immediately infrm PJM f the inability t perfrm the directive s that PJM can implement alternate remedial actins. Revisin: 52, Effective Date: 12/22/2017 PJM

14 Sectin 1: Transmissin Operatins Requirements Nte: A PJM Transmissin Owner shall discnnect an affected facility if an verlad n a transmissin facility r an abnrmal vltage r reactive cnditin persists and equipment is endangered. The PJM Transmissin Owner shall ntify PJM prir t switching s PJM can perfrm a study, if time permits, therwise, immediately thereafter.

In ding this, PJM cnsiders transmissin cnstraints, restrictins, and/r limitatins in the verall peratin f the PJM RTO. Describing this peratin is the fcus f this manual. The PJM RTO shall be perated such that the fllwing are nt exceeded: Revisin: 52, Effective Date: 12/22/2017 PJM

15 Sectin 1: Transmissin Operatins Requirements Transmissin facility thermal limits Vltage limits Transfer limits Stability limits IROL Althugh, the PJM RTO shall be perated such that limitatins are nt vilated, it is recgnized that ccasinally, fr varius reasns, thermal limitatins can be exceeded fr shrt perids under cntrlled cnditins withut adversely impacting system reliability r damaging equipment. All exceptins must be dcumented in Sectin 5 f this manual. Fr example, the Cnstraint Management Mitigatin prcedure can be used during shrt time switching perids when adhering t all f the requirements and parameters. Shuld the PJM RTO at any time enter int an unknwn perating state due t a catastrphic failure f the ICCP links r lss f EMS analysis tls, it will be cnsidered an Emergency and peratins shall be restred t respect prven reliable pwer system limits within 30 minutes in accrdance with NERC standards. PJM relies n Transmissin Owners t serve as a backup t PJM, mnitring BES facilities, when the PJM EMS is inperable (TOP-007-0). PJM Transmissin Owners shall ntify PJM dispatch within 15 minutes when their TO analysis packages are unavailable (TOP R4). In general, PJM may be in an unknwn state when bth PJM and TO analysis packages are unavailable. PJM perates the PJM RTO s that immediately fllwing any single malfunctin r failure, the facility ladings are within apprpriate thermal limits, while maintaining an acceptable vltage prfile. Fr details abut PJM s thermal peratin, please see Sectin 2: Thermal Operating Guidelines. Fr mre infrmatin abut PJM s vltage requirements, refer t Sectin 3: Vltage and Stability Operating Guideline. These ptential malfunctins r failures, such as the sudden and unplanned lss f a generating unit, transmissin line, r transfrmer, are called cntingencies. PJM defines a cntingency as a pssible event resulting in the failure r malfunctin f ne r mre facilities. PJM Dispatch utilizes EMS Netwrk Applicatins and market tls in rder t maintain system reliability. Netwrk applicatins evaluate pre/pst-cntingency thermal and vltage limits. In additin, the Transfer Limit Calculatr (TLC) simulates transfers in rder t assess vltage cllapse cnditins fr reactive interfaces. PJM Operatrs generate reprts which prvide generatr shift factrs, phase angle regulatr sensitivity factrs, and lad distributin factrs. The infrmatin cntained within these reprts, the PJM State Estimatr slutin and unit bid infrmatin serves as the input data fr PJM Market Tls. Thrugh the use f PJM Market Tls, PJM Operatrs have the ability t use cst-effective generatin adjustments t cntrl thermal/vltage cnstraints n a pre-cntingency basis. Nte: PJM Transmissin Owners that wn BES facilities and serve lad greater than 300 MW must have a real-time analysis package r have their BES facilities be bservable within anther TO analysis package. Revisin: 52, Effective Date: 12/22/2017 PJM

16 Sectin 1: Transmissin Operatins Requirements Prir t initiating redispatch t cntrl flws within limit criteria, PJM Dispatch cmpares PJM EMS Security Analysis results with Transmissin Owners EMS Security Analysis Results. Pre-cntingency, Pst-Cntingency flws and ratings are cmpared. If a difference exists between PJM and Transmissin Owner Security Analysis results, PJM will perate t the mst cnservative results until the difference can be ratinalized. If the difference is significant, the fllwing guides will be fllwed t quickly reslve the difference: PJM and Transmissin Owner identify mdeling issue and perate t mst cnservative slutin. PJM investigates mdeling issue and attempts t reslve within 1 hur. This may invlve verificatin f distributin factrs using Seasnal PSS/E lad flw case r the cntingency definitin via implementing cntingency in a pwer flw slutin and ensuring switching devices are in their prper psitin. If discrepancy is > 5% and expected t last 2 hurs, PJM Dispatch will cntact PJM supprt staff and request Transmissin Owner t cntact supprt staff. PJM and Transmissin Owner n-call supprt staff will wrk tward reslving mdeling difference. PJM and Transmissin Owner agree t defer t mst accurate analysis in lieu f perating t mst cnservative results, when difference is understd r reslved. PJM and Transmissin Owner supprt staff attempt t crrect mdeling differences within 24 hurs. Cntingency Analysis Single Cntingency One event that takes ne r mre facilities ut f service. A Single Facility is any ne cmpnent/facility with impact t the BES, excluding bus sectins that can be remved frm service by its wn primary relay and breaker prtective equipment. Single cntingencies may discnnect multiple generating facilities (plant with single cnnectin leads t the bulk pwer system) r multiple transmissin facilities (radial lines with tapping substatins) frm service. PJM Security Analysis applicatins simulate the single facility failure r malfunctin f critical equipment (facilities simulated in cntingency analysis are nt restricted t the PJM mnitred facility list) including lines, transfrmers, Phase Angle Regulatrs (PARs), generatrs, capacitrs, and reactrs whse lss r failure culd result in limit vilatins n PJM Mnitred Facilities. Nte: PJM des nt nrmally mdel r perate t single breaker failures due t the lw prbability f ccurrences; hwever, Sectin 5 f this manual cntains an perating prcedure t mitigate single breaker failures. Revisin: 52, Effective Date: 12/22/2017 PJM

17 Sectin 1: Transmissin Operatins Requirements Nte: Under sme unusual cnditins, including severe weather r ther special circumstances such a change t the Hmeland Security Level, PJM shuld cnsider implementing cnservative peratin including cntrl fr the simultaneus ccurrence f mre than ne cntingency, substatin circuit breaker utages, circuit breaker failure, and substatin bus utages as apprpriate (PJM M-13: Emergency Operatins, Sectins 3 and 4). PJM uses apprpriate pre and pst cntingency prcedures which are dcumented in this manual t: Maintain acceptable vltage levels Maintain peratin within stability limits Maintain peratin within transfer limits Minimize the risk f cascading interruptins t the transmissin system Prevent physical damage t system transmissin facilities Eliminate thermal verlads The cnsequences f vilating these limits may lead t PJM RTO instability, vltage cllapse, equipment damage, r lss f custmer lad. The bjective f PJM is t perate the transmissin facilities such that system reliability is maintained. Once a cntingency ccurs the system is readjusted as required and analysis fr the next wrst cntingency is perfrmed. The PJM dispatcher directs actins t restre the system t an acceptable state. Fr mre infrmatin see Sectin 2: Thermal Operating Guidelines and Sectin 3: Vltage and Stability Operating Guidelines. Duble Cntingency Tw different events that ccur simultaneusly and result in the lss f tw r mre facilities. Nte: A single cntingency can cnsist f ne r mre transmissin facilities. A duble circuit twer line (DCTL) cntingency is the simultaneus lss f tw single cntingencies. Nte: If a Transmissin Owner wishes t perate t cntrl fr DCTL cntingencies, it may d s using its wn internal equipment after cmmunicating with the PJM dispatcher. Nte: PJM system peratins will implement actins t cntrl fr system cngestin caused by DCTL cntingencies resulting frm the declaratin f Cnservative Operatins. PJM will issue a PCLLRW when calculated pst-cntingency flws exceed Lng Term Emergency (LTE) ratings. PJM will initiate redispatch f generatin when calculated pst-cntingency flws exceed the Lad Dump (LD) rating permitting ff-cst generatin t set LMP. Revisin: 52, Effective Date: 12/22/2017 PJM

18 Sectin 1: Transmissin Operatins Requirements 1.4 Reclsing Lines That Have Tripped The PJM RTO uses varied philsphies when reclsing EHV lines that have tripped and the autmatic reclse has nt been successful. These philsphies differ based n the EHV line autmatic reclsing design and perating practice. Nte: Transmissin Owners shall prmptly ntify PJM f any BES facility that have tripped and crdinate restratin effrts PJM Mid-Atlantic Regin If an EHV (Extra High Vltage) aerial transmissin line trips and des nt autmatically reclse, it shuld be manually reclsed within five minutes after tripping. If an EHV line trips and returns t service by autmatically reclsing (r by manually reclsing if aut reclsing fails t ccur and the line is tried-back nce manually), the PJM dispatcher is authrized t perate at the current transfer levels r at reduced transfer levels. If an EHV line trips and des nt return t service when reclsed autmatically (r if manual reclsing als fails after the line is tried-back nce manually), PJM perfrms the fllwing activities: Immediately reduces the reactive perating limits t the level with the line ut-f-service. Order the line t be tried-back within five minutes after cnferring with the Transmissin Owner(s) f the line. If the line returns t service after the five minute try-back, the reactive perating limits may remain reduced until a patrl f the line has been cmpleted r until the PJM dispatcher judges that the limit reductin is n lnger necessary.

In this sectin yu will find the fllwing infrmatin: Hw PJM perates t prevent thermal prblems (see Thermal Limit Operatins Criteria ). 2.1 Thermal Limit Operatin Criteria The PJM RTO is perated s that lading n all PJM SOL are within nrmal cntinuus ratings, and s that immediately fllwing any single facility malfunctin r failure, the lading n all remaining facilities can be expected t be within emergency ratings. (All deviatins frm nrmal prcedure must be apprved and dcumented in Sectin 5.) This principle requires that actins shuld be taken befre a malfunctin r failure ccurs in rder t cntrl pst-cntingency lading n a pre-cntingency basis. Sme examples f pssible pre-cntingency actins include pre-arranged apprved switching, use f apprved special purpse relays, Phase Angle Regulatr tap adjustments (PARs), redispatch, and transactin curtailment. These actins can be used pre-cntingency t cntrl pst-cntingency peratin s as nt t exceed emergency ratings. These pre-cntingency ptins are simulated by PJM when perfrming the day-ahead analysis f the system. Fllwing any malfunctin r failure, all remaining facilities r prcedures f PJM are utilized, as required in accrdance with Exhibit 1 r as practical, t restre PJM RTO cnditins within 30 minutes t a level that restres peratin within nrmal ratings and prtects against the cnsequences f the next malfunctin r failure. Transmissin verlads, bth actual and pstcntingency, are crrected within this time requirement. PJM uses the fllwing techniques t cntrl cntingency r system vilatins: Adjusting PARs Switching reactive devices in/ut f service r adjusting generatr MVAR utput Switching transmissin facilities in/ut f service Adjusting generatin MW utput via redispatch Adjusting imprts/exprts Issuing a TLR (Transmissin Lading Relief) If the abve directed actins d nt relieve an actual r simulated pst-cntingency vilatin, then emergency prcedures may be directed, including drpping r reducing lad as required. A Transmissin Owner has the right t use its wn devices after crdinating with PJM (i.e., Phase Angle Regulatrs PARs) t crrect fr duble circuit twer line cntingency verlads in their wn system, ensuring that this crrective actin des nt aggravate an existing cntingency r create a new cntingency. When a Transmissin Owner detects a duble circuit twer line cntingency and the PJM RTO detects a single cntingency, bth f which require different crrective strategies, the Transmissin Owner and the PJM RTO dispatchers cmmunicate t wrk ut an verall slutin fr bth prblems, prvided the net impact in MWs Revisin: 52, Effective Date: 12/22/2017 PJM

28 Sectin 2: Thermal Operating Guidelines shifted fr ther Transmissin Owners des nt exceed that which is required fr the single cntingency. Nte: Under nrmal peratins, PJM des nt perate fr duble-circuit twer line (DCTL) cntingencies. Hwever, PJM may perate fr DCTL cntingencies if Cnservative Operatins are declared. Nte: Generatin redispatch fr DCTL cntingencies will be brne by the Transmissin Owner and will nt be allwed t set LMP while nt under Cnservative Operatins. Nte: PJM system peratins will implement actins t cntrl fr system cngestin caused by DCTL cntingencies resulting frm the declaratin f Cnservative Operatins. PJM will issue a PCLLRW when calculated pst-cntingency flws exceed Lng Term Emergency (LTE) ratings. PJM will initiate redispatch f generatin when calculated pst-cntingency flws exceed the Lad Dump (LD) rating permitting ff-cst generatin t set LMP Facility Ratings Three sets f thermal limits are prvided fr all mnitred equipment: Nrmal limit Emergency limit Lad dump limit PJM systems expect Nrmal (cntinuus), Emergency (lng term and shrt term emergency are set equal unless specifically apprved therwise) and Lad Dump limits. Eight ambient temperatures are used with a set fr the night perid and a set fr the day perid; thus, 16 sets f three ratings are prvided fr each mnitred facility. Ambient temperatures f 95, 86, 77, 68, 59, 50, 41, and 32 F fr bth day and night perids are cllated t cnstitute the 16 rating set selectins. All Transmissin Owners and the PJM RTO s security analysis prgrams must be able t handle all 16 sets and allw perating persnnel t select the apprpriate rating set t be used fr system peratin. With a minimum f tw set selectins required daily (day/night), the Transmissin Owner and the PJM RTO security analysis prgrams use these 16 ambient temperature rating sets fr mnitring actual and cntingency verlads. All temperatures assciated with the ambient temperature rating data sets are in degrees Fahrenheit. Certain facility ratings can be further adjusted by average bus vltage. The PJM RTO security analysis prgrams d nt reflect these vltage adjustments in the 16 ambient temperature rating set selectins. Crdinatin is required t ensure reliable PJM RTO peratins. The PJM RTO examines the set f thermal ratings that apply t Mnitred Transmissin Facilities during all perating perids.

The PJM RTO dispatcher perfrms the fllwing actins: Any discrepancy between the PJM RTO and a Transmissin Owner fr a facility rating is lgged and reprted t the PJM Real-Time Data Management Department fr reslutin. The immediate reslutin fr a rating discrepancy is t use the lwer f the tw disputed values until a mre permanent reslutin can be affected. If it becmes necessary in actual peratins t initiate ff-cst peratin fr a facility, the peratin is based n PJM RTO security analysis prgram infrmatin, unless a mre limiting cnditin is detected by the Transmissin Owner s security analysis prgram. When a Transmissin Owner s facility is experiencing cnstraints in an area that has an actual temperature (degrees Fahrenheit) less than the ambient temperature rating set being used by the n-line prgrams, the actual temperature in the area is used t select a mre apprpriate rating set fr that facility. The selectin is made frm the remaining 15 sets. This adjustment is exercised when bth the PJM RTO and the Transmissin Owner are in agreement, and have lgged that agreement. Any adjustment t facility ratings, such as the temprary use f a different rating, must be apprved by PJM. These changes must be submitted t PJM thrugh the Transmissin Equipment Ratings Mnitr (TERM) cnsistent with PJM M-3A: Energy Management System (EMS) Mdel Updates & Quality Assurance (QA), Appendix A: TERM Prcessing Ratings Data Check List. TERM is an internet-based interactive database lcated thrugh edart. The prcedure and the rating are reviewed prir t apprval by PJM. If an emergency rating change is needed, the change can initially be apprved via phne call t PJM; hwever, a TERM ticket must still be entered by the next business day. PJM requires a separatin between Emergency and Lad Dump ratings in rder t enhance PJM Operatr awareness. In the event where the Transmissin Owner (TO) calculated Lad Dump and Emergency Ratings are the same, the Emergency Rating submitted by the TOs shall be, at a minimum, 3% lwer than the submitted LD rating. If this change results in a nrmal rating that is higher than the LTE rating, the TO shall, at a minimum, make the nrmal rating equal t the LTE rating. Lad Dump ratings are determined t aid the system peratr in identifying the speed necessary t relieve verlads. Operatin at a Lad Dump rating shuld nt result in any facility tripping when actually laded at that value fr at least 15 minutes. Fr a facility lading t apprach the Lad Dump rating, either multiple cntingencies must have ccurred r the system had been perated beynd first cntingency limits. Nte: PJM dispatchers must return actual flws belw Emergency ratings within 15 minutes and belw Lad Dump ratings within 5 minutes, as indicated in the tables belw Shrt-Term Emergency Ratings The existence f apprved shrt term emergency (STE) ratings can affect the time allwed befre implementing lad shedding.

30 Sectin 2: Thermal Operating Guidelines If the actual flw is greater than the LTE rating but less than the STE rating, then the time t crrect (using lad shedding) is equal t the time referenced by the STE rating. (e.g. if a 30 minute STE rating is prvided and the actual flw exceeds the LTE rating but des nt exceed the 30 minute STE rating, then the time t crrect using lad shedding, is 30 minutes nt 15 minutes). If ther real-time mnitring is available such as transfrmer temperature, line tensin, etc., the Transmissin Owner may request that special prcedures fr their use be evaluated by PJM, and, if apprpriate, included in Sectin 5 f this manual t evaluate the urgency f identified lad shed as an alternatives. If the actual flw is greater than the STE rating but less than the Lad Dump rating, then the time t crrect, using lad shedding is 15 minutes.

Similar t the prcess fr submitting a transmissin utage request, the request t change ratings shuld be made cnsistent with PJM M-3A: Energy Management System (EMS) Mdel Updates and Quality Assurance (QA), Appendix A: TERM Prcessing Ratings Data Check List. PJM s Real Time Data Management Department evaluates the request. The request must be evaluated befre the start date f the ticket, but preferably, it is apprved tw days prir t the start date. PJM s Real Time Data Management Department evaluates the request by cmparing the ld and new ratings and checking them against any future utages fr reasnableness. The Transmissin Owner can lk int TERM t see if their request has been apprved. After a request has been apprved, PJM s Real Time Data Management Department implements the changes int the EMS.

The system readjustment shuld take place within 30 minutes but a 60-minute maximum time is allwed prir t issuing a Pst-Cntingency Lcal Lad Relief Warning. In additin, the pst-cntingency vltage, resulting frm the simulated ccurrence f a single cntingency utage, shuld nt vilate any f the fllwing limits: Pst-cntingency simulated vltage lwer than the Emergency Lw vltage limit, r higher than the Emergency High vltage limit. Pst-cntingency simulated vltage drp greater than the applicable Vltage Drp limit (in percent f nminal vltage). Pst-cntingency simulated angular difference greater than the setting f the synchrcheck relay less an apprpriate safety margin (ten degrees fr a 500 kv bus). The angular difference relates t the ability t reclse transmissin lines. PJM bus vltage limits by vltage level are as shwn in Exhibit 3. PJM peratin requires that actins shuld be taken n a pre-cntingency basis in rder t cntrl peratins after a malfunctin r failure happens. Sme examples f pssible precntingency actins include pre-arranged apprved switching f capacitrs r reactrs, Phase Angle Regulatr tap adjustments (PARs), redispatch, and transactin curtailment. These actins can be used pre-cntingency t cntrl pst-cntingency peratin s as nt t exceed emergency ratings n a simulated basis. These pre-cntingency ptins are cnsidered by PJM fr inclusin in the day-ahead analysis. PJM des nt have an Under Vltage Lad Shed prgram, cntrlling t vltage limits n a pre-cntingency basis in rder t avid lad shed. Vltage Drp Vilatin limits are utilized t prevent vltage instability, which culd result in system vltage cllapse. Vltage Drp Vilatin limits will be evaluated by PJM based n studied system vltage characteristics. These limits can vary ver a range f values depending n lcal transmissin system characteristics. Lad dump limits are prvided t aid the system peratr in identifying the speed necessary t relieve cnstraints. Operatin at a lad dump limit shuld nt result in any facility tripping r vltage cllapse when actually perated at that value fr at least 15 minutes. In rder fr an peratr t be faced with actual vltages appraching the lad dump limit either multiple cntingencies must have ccurred r the system had been perated beynd first cntingency limits. PJM will review with each TO the PJM default vltage limits and the apprpriateness f using individual TO limits based n design and dcumented past peratin. Revisin: 52, Effective Date: 12/22/2017 PJM

In rder t prvide this assurance, the nuclear pwer plant peratrs must be ntified whenever actual r pst-cntingency vltages are determined t be belw acceptable limits. This requirement applies t all cntingencies invlving the tripping f the nuclear plant generatr r any transmissin facility as the cntingent element. The ntificatin is required even if the vltage limits are the same as the standard PJM vltage limits. Revisin: 52, Effective Date: 12/22/2017 PJM

42 Sectin 3: Vltage & Stability Operating Guidelines Nuclear plants may have vltage limits that are mre restrictive than standard PJM vltage limits. In the case where standard PJM vltage limits, as defined by the Transmissin Owner (TO), are mre restrictive, PJM will direct redispatch withut cnsultatin f nuclear plants after all nn-cst measures are implemented; hwever, PJM will still ntify the Nuclear Owner f the vilatin t the limit. Off-cst generatin will set Lcatinal Marginal Prices (LMP). In the case where nuclear plant vltage limits are mre restrictive than standard PJM vltage limits, all csts required t mitigate the vilatins will be brne by the generatin wner. PJM s EMS mdels and perates t the mst restrictive substatin vltage limit fr bth actual and N-1 cntingency basis. PJM will initiate ntificatin t nuclear plants if the PJM EMS results indicate nuclear substatin vltage vilatins. This ntificatin shuld ccur within 15 minutes fr vltage cntingency vilatins and immediately fr actual vltage vilatins. T the extent practical, PJM shall direct peratins such that the vilatin is remedied within 30 minutes Cmmunicatin All cmmunicatin f future and current peratins between PJM and the nuclear plant shuld be thrugh the Transmissin Owner (TO). If there is any cnfusin abut a cmmunicatin, the plant can talk directly with PJM, hwever, the Transmissin Owner shuld be appraised f the discussin if PJM t a nuclear plant direct discussins are needed the preferred methd wuld be a 3-way call amng all parties (i.e., inclusin f TO). If ff-cst peratins are required based n a mre restrictive Nuclear Plant vltage limit, the Nuclear Plant r their representative (Nuclear Duty Officer) may cnsult with the related MOC and evaluate whether an alternative such as perating at a reduced utput wuld alleviate the vltage vilatin and is mre cst effective. PJM will prvide the apprximate nuclear plant reductin, if applicable Infrmatin Exchange Nrmally, PJM des nt prvide infrmatin relative t transmissin peratin t any individual Market participant withut prviding that infrmatin t all. Hwever, in this unique cnditin where the public safety requirement is t have a reliable surce fr safe unit shutdwn and/ r accident mitigatin; it is imperative that specific infrmatin be prvided t a nuclear plant (this infrmatin shuld nt be prvided t their marketing members). If PJM peratrs bserve vltage vilatins r anticipate vltage vilatins (pre r pst-cntingency) at any nuclear statins; PJM peratrs are permitted t prvide the nuclear plant with the actual vltage at that lcatin, the pst-cntingency vltage at that lcatin (if apprpriate) and limiting cntingency causing the vilatin. The peratin fr mre restrictive Nuclear Plant Vltage Limits at these nuclear statins shuld nt be psted r prvided t the Market via Data Viewer, nce ff-cst peratins are initiated. PJM Actins: PJM ntifies nuclear plant, thrugh Transmissin Owner, f calculated pst-cntingency vilatins t mdeled vltage limits (Transmissin Owner r mre limiting Nuclear Plant Vltage Limits). PJM ntify nuclear plant, thrugh Transmissin Owner, f vilatins t actual vltage limits (Transmissin Owner r mre limiting Nuclear Plant Vltage Limits). Vilatins f mre restrictive Nuclear Plant Vltage Limits must be agreed upn by the nuclear plant and lgged by PJM. All nn-cst actins shuld be implemented prir t MW adjustments.

43 Sectin 3: Vltage & Stability Operating Guidelines All csts required t mitigate vilatins f mre restrictive Nuclear Plant Vltage Limits will be brne by the generatin wner. Cntrlling actins must be cst-capped, if applicable. LMP shall nt be used t cntrl the vltage at these lcatins. TLR shall nt be used t cntrl the vltage at these lcatins. PJM will mnitr the apprpriate vltage limits based n changes prvided. PJM ntify nuclear plant, thrugh Transmissin Owner, when vltage level is restred within limits (and stable). Attempt t cntrl mre restrictive nuclear plant vltage limitatins within 30 minutes. Transmissin Owner Actins: The Transmissin Owner shall independently mnitr fr Nuclear Plant actual and cntingency vltage vilatins as reflected n the Transmissin System. Transmissin Owner will cmmunicate this ntificatin frm PJM t the nuclear plant (Transmissin Owner r mre limiting Nuclear Plant Vltage Limit vilatins). Transmissin Owners will mnitr the apprpriate vltage limits based n changes t mre limiting Nuclear Plant Vltage Limits as prvided by the Nuclear Duty Officer (NDO). Nuclear Plant Actins: Nuclear plant will ntify PJM, thrugh Transmissin Owner Shift Managers, when different (new r default) vltage limits shall be used based n varius plant service lading cnditins, design basis calculatin revisins. Determine internal plant ptins, and if apprpriate, prvide revised limits. Crdinate with MOC t evaluate PJM prvided redispatch ptin (n cst r unit infrmatin will be prvided).

PJM requires that autmatic capacitr switching capability n facilities 230 kv and abve be dcumented in Sectin 3 f this manual. PJM authrizes the Lcal Transmissin Cntrl Center t autmatically r manually switch/adjust reactive devices cnnecting t 138 kv and belw withut ntifying PJM. Transmissin Owners shall evaluate the impact f switching BES capacitr/reactrs r adjusting BES LTC n vltage limits and lagging/ leading MVAR reserves. The evaluatin may require use f EMS Security Analysis r ther analysis packages depending n system cnditins and prximity t limits. Transmissin Owners shall request PJM t study the impact f switching capacitr/ reactrs r LTC adjustments if the TO determines they are unable t analyze the impact n SOL related equipment. When deviating frm the generatr vltage schedule the Transmissin Owner shall crdinate with the PJM dispatcher s that PJM can determine if the change is detrimental t PJM reliable/ecnmic peratin. When PJM requests t change vltage r VAR schedule, PJM shuld discuss the changes with the Transmissin Owner and if the recmmendatin des nt cause a defined limitatin the Transmissin Owner shuld implement the PJM request. PJM has peratinal cntrl f the reactive facilities (transmissin caps, LTC's, and generatr regulatin). If internal plant limits (r Transmissin Owner lcal limits) restrict the request they shuld be lgged s that PJM can investigate and recmmend changes t plant facilities if apprpriate. Generatin Owners that pssess generatin resurces equipped with Pwer System Stabilizers are required t cmmunicate PSS status t the apprpriate Transmissin Owner as well as t PJM via the edart utage reprting system EHV Transfrmer LTC Operatin The PJM dispatcher has peratinal cntrl f and crdinates the peratin f the EHV LTC transfrmer taps. In general, EHV LTC transfrmer tap changers are nt perated under autmatic vltage cntrl but are perated in crdinatin with all ther Bulk Electric System vltage cntrl facilities. Operatin f the PJM RTO is crdinated in an attempt t minimize capacitr switching peratin and transfrmer tap changes. PJM crdinates with the Lcal Cntrl Centers, all switching f the Bulk Electric System capacitrs & reactrs t assist the system fr actual r pst-cntingency situatins. Lcal cnditins may require sme deviatins Vltage Cntrl Optins fr Nn-Tariff Facilities On ccasin, PJM is requested t dispatch generatin t prtect PJM member equipment/ facilities where that equipment is nt included in the PJM tariff, and therefre nt accmmdated by standard PJM redispatch.

45 Sectin 3: Vltage & Stability Operating Guidelines Off-cst examples: If requested t run generatin fr a distributin related prblem PJM will accmmdate a member s request fr ff-cst peratin. Apprpriate billing will be made t the requestr. [A PJM Transmissin Owner may request limits t PJM OATT facilities t prtect their distributin system reliability (nn-pjm OATT facilities). PJM will bill the PJM Member fr any resulting ff-cst peratin.] If requested t run generatin t prtect a generating statin r ther nn-tariff facility, PJM can accmmdate a PJM member s request fr the ff-cst generatin assignment. PJM will bill the PJM Member fr any resulting ff-cst peratin. If requested t run generatin fr a Transmissin Owner determined nn-pjm reliability limit, PJM will accmmdate that member s request fr ff-cst peratin. Apprpriate billing will be made t the requestr. As an alternative t PJM directed ff-cst generatin, the requestr culd enter int an agreement with any generatin prvider; this agreement wuld be treated independent frm the PJM billing prcess Bulk Electric System Capacitr/SVC Operatin The PJM dispatcher crdinates the peratin f Bulk Electric System capacitrs. Capacitrs shuld be kept in service whenever they are beneficial t the PJM RTO transfer capability r reliability. Nte: The capacitr banks at each installatin perate independently f each ther under nrmal switching peratins. Under nrmal cnditins, the PJM dispatcher des nt request that bth banks f capacitrs at ne lcatin be brught n r ff simultaneusly; generally at least five minutes between switching is desirable. The PJM dispatcher mnitrs the system vltage prfile and the transfer capability f the PJM RTO and requests capacitr switching r transfrmer tap changes in a timely manner. Operatin f the PJM RTO is crdinated in an attempt t minimize capacitr switching peratin and transfrmer tap changes. PJM crdinates with the Lcal Cntrl Centers, all switching f the 230 kv and 500 kv capacitrs and variable reactrs t assist the system fr actual r pst-cntingency situatins. Lcal cnditins may require sme deviatins. The 500 kv LTC transfrmer taps shuld be adjusted t cntrl the system vltage regardless f the capacitr's in r ut-f-service status. A bank f capacitrs shuld nt be switched in-service if the vltage n the bus, upn which it is lcated, wuld vilate vltage limits. The PJM RTO maximum vltage limits shuld nt be exceeded n an actual r simulated pstcntingency basis. As the PJM RTO vltage appraches limits, the PJM dispatcher analyzes and estimates the future system vltages and decides if there will be a need t remve any r all capacitrs frm service. The PJM dispatcher arranges t remve capacitrs frm service prir t the PJM RTO vltage reaching the maximum limits. If PJM s simulated pst-cntingency analysis r a Transmissin Owner s real-time mnitring prgram detects that the first cntingency lss f a facility results in a Bulk Electric System bus exceeding its Emergency High limit, the PJM dispatcher evaluates the remval f any r all capacitrs at that bus frm service as necessary.

This can cause serius equipment damage. The steady state vltage at the pen end f an uncmpensated transmissin line is always higher than the vltage at the sending end. This phenmenn, knwn as the Ferranti effect, ccurs because f the capacitive charging current flwing thrugh the series inductance f the line. The equatin representing the Ferranti effect is: where: V1 Open End Vltage V2 Clsed End Vltage B Phase Cnstant ( /mile fr all cmpensated transmissin lines) L Line Length in Miles In the event PJM security analysis prgrams are nt available, the Ferranti equatin may be used as a guide t ptential vltage rise during PJM 500 kv line switching peratins.

If a PJM Transmissin Owner identifies a specific vltage reliability limit that is mre restricting than the PJM Baseline Vltage Limits, PJM will use that vltage reliability limit prvided by the Transmissin Owner as the PJM Vltage Reliability Operating Limit. Hwever, this use will depend n the cnditin that the facility is specifically identified as a PJM Open Access Transmissin Tariff ( PJM OATT ) facility, and the limit is specifically identified as required fr reliable peratin. The PJM Vltage Reliability Operating Limit will be the mre restrictive f either the PJM Baseline Vltage Limit r the Transmissin Owner prvided vltage reliability limit (exceptins are as nted in Exhibit 3). PJM des nt charge r bill a PJM Transmissin Owner fr ff-cst peratin f a PJM OATT facility as described abve.

The PJM dispatcher requests Lcal Cntrl Center peratrs t direct all generatrs, synchrnus cndensers and SVCs within their zne t absrb reactive pwer. The PJM dispatcher requests neighbring Balancing Authrities t assist in reducing vltage. The PJM dispatcher directs the adjustment 500/230 kv transfrmer taps t ptimize system vltage. Adjustment f transfrmer taps will be crdinated and agreed t between PJM and the Transmissin Owner befre changes are made. The greatest effect t cntrl system vltage is attained by adjusting all 500/230 kv transfrmer taps. The PJM dispatcher requests the Transmissin Owners t pen apprved and effective EHV circuits. The PJM dispatcher perfrms the fllwing tasks: Verifies thermal cnditins with n-line study prgrams. Uses cmputer prgrams t study the simulated effects f switching and the steady state vltage respnse.

Opening EHV Lines fr Vltage Cntrl When high vltage cnditins are expected n the PJM RTO, the PJM dispatcher uses PJM Security Analysis prgrams t study pssible actins (i.e., pening an EHV line) and crdinates an peratinal plan befre the situatin becmes severe. If system vltages get t high, it may be difficult (if nt impssible) t remve a line frm service due t the vltage rise experienced at the pen end f the circuit being remved frm service. Crrective actins have a maximum effect nly when they are accmplished prir t experiencing the prblem. During high vltage cnditins, pening an EHV circuit has a psitive effect in reducing system vltages fr tw reasns: It increases lsses n the rest f the PJM EHV system. It eliminates the capacitive charging f the line. PJM has identified several circuits that, in the past, have been effective in cntrlling general PJM RTO high vltage cnditins when they are remved frm service. Suggested EHV circuits t be studied are: AEP area Jacksns Ferry-Wyming 765 kv line Dumnt-Greentwn 765 kv line Mid Atlantic Area Alburtis-Juniata kv line * Cnemaugh-Juniata kv line * Nte: This ptin may be preferable if ne r bth Cnemaugh units are ff-line.

Off-peak planned utages/returns shuld be delayed until prjected system cnditins permit pen-ended vltages t be cntrlled within Emergency High Vltages, but n lnger than the next n-peak perid. PJM Dispatch can deviate frm guidelines abve if reliability issues are prjected with the transmissin facility ut-f-service r if delaying the utage raises reliability cncerns.

This ensures that n single cntingency lss f generatin r transmissin in r utside the PJM RTO causes a vltage drp greater than the applicable vltage drp criteria. In additin, special perating prcedures, addressing reactive issues, are identified in Sectin 5. Additinal interfaces will be established by PJM Operatins Planning as required. 3.9 Stability Limits The PJM RTO established stability limits fr preventing electrical separatin f a generating unit r a prtin f the PJM RTO. PJM recgnizes three types f stability: Steady State Stability - A gradual slw change t generatin that is balanced by lad. Transient Stability - The ability f a generating unit r a grup f generating units t maintain synchrnism fllwing a relatively severe and sudden system disturbance. The first few cycles are the mst critical time perid. Dynamic Stability - The ability f a generating unit r a grup f generating units t damp scillatins caused by relatively minr disturbances thrugh the actin f prperly tuned cntrl systems. PJM will perate the facilities that are under PJM peratinal cntrl such that the PJM system will maintain angular and vltage stability fllwing any single facility malfunctin r failure. In general, stability is nt a limiting cnstraint n the PJM RTO. In additin t the special perating prcedures addressing stability limit issues that are presented in Sectin 5, PJM utilizes a real-time Transient Stability Assessment (TSA) tl. TSA can mnitr and determine transient stability f the system subject t a select set f EMS cntingencies fr balanced and unbalanced faults. PJM mdels a select set f three-phase faults with nrmal clearing and single-phase faults with delayed clearing. The cntingencies r faults are in alignment with mst planning events as defined in TPL categries P1 thrugh P4. TSA cmputes stability limits by using real time netwrk mdels. It interfaces with the EMS and uses the State Estimatin slutin. Other input data includes the dynamic mdel fr ver 3000 generatrs and fault clearing times fr specific equipment. Fr equipment withut a specific fault clearing time, TSA will use znal default clearing times. TSA als calculates and prvides recmmended stability cntrl measures t prevent generatr instability. Typically, the cntrl measure is expressed in terms f generatr-specific MW adjustment. In sme cases, a Mvar adjustment may reslve a stability issue. TSA is used t mnitr and cntrl the generatrs with knwn stability cncerns as defined in Manual-03: Sectin 5. Since TSA uses real-time system cnditins t assess stability, the limits tend t be less cnservative r less restrictive than the M-03 Sectin 5 prcedures. The Sectin 5 limits are usually determined using cnservative assumptins in rder t cver a wider range f perating cnditins. Fr scheduled transmissin utages, TSA studies are used Revisin: 52, Effective Date: 12/22/2017 PJM

PJM will als use the Sectin 5 stability limits in certain cases, such as when TSA is dwn r the plant/generatr mdel has nt been fully benchmarked Prcess fr Handling Generatr Stability Limitatins The Reliability Limited Generatin Cmpensatin Task Frce established the fllwing prcedure n hw PJM currently handles Stability Issues n the transmissin system. When a stability issue is identified and advanced crdinatin is nt pssible, PJM will: Cnfirm/calculate the stability limit and cmmunicate the limit t the generatr(s) as quickly as pssible and prir t DA market submissin when practical. Create an interface that wuld be used in the Day Ahead and Real Time Market s that LMP will be utilized t reflect the stability cnstraints.

60 Sectin 3: Vltage & Stability Operating Guidelines Warning (See M-13, PJM Emergency Prcedures Manual) has been issued. An RRC may als be needed during light lad cnditins, such as a Minimum Generatin Alert (See M-13, PJM Emergency Prcedures Manual) issuance. In additin, PJM may issue an RRC nce a week, such as a Sunday check, fr testing purpses. Fr PJM, reactive pwer is expressed in MVAR, and fr the purpses f an RRC, that MVAR reserve is expressed: as MVAR available (lagging) t the system fr a Peak (heavy-lad) RRC; as MVAR available (leading) t be taken ff the system fr a Valley (light-lad) RRC. Reactive assets fr the PJM RTO area cnsist f PJM mdeled generating units, synchrnus cndensers, static var cmpensatrs (SVCs), capacitrs, and reactrs. PJM assesses the reactive reserve f the assciated equipment via three (3) key metrics: 1. Capability: The lagging (and/r leading) capability fr a given piece f reactive equipment. a. Fr generating units, synchrnus cndensers and SVCs, the capability is cmprised f the permissible range f peratin fr the equipment, als knwn as the Reactive Pwer Capability Curve. Fr an RRC, PJM utilizes the lagging/leading MVAR pints f the curve crrespnding t the real-time real pwer (MW) utput f the facility. Thus, capability is expressed as a maximum (lagging) and minimum (leading) MVAR range. i Reduced/expanded capability shuld be cmmunicated thrugh an edart ticket and cmmunicated t PJM Dispatch. b. Fr capacitrs and reactrs, the capability is single MVAR value crrespnding t the maximum (lagging) MVAR capability fr capacitrs, r a minimum (leading) MVAR capability fr reactrs, PJM wuld anticipate at unity pwer factr. 2. Status: Status reflects the real-time cnnectivity t the PJM system, and is expressed as Online r Offline. Equipment real-time status is t be prvided t (typically derived frm circuit breaker status and/r MW/MVAR utput) PJM via telemetry. Real-time status f an Autmatic Vltage Regulatr (AVR) fr a given generatr r synchrnus cndenser, r the autmatic/manual respnse fr a given SVC, must als be cmmunicated t PJM Dispatch. Unless therwise agreed t r cmmunicated t PJM Dispatch: a. When a generatr is abve ecnmic minimum real pwer utput, PJM cnsiders the AVR t be in-service/autmatic mde and regulating vltage. b. When a synchrnus cndenser is nline and cnnected t the grid, PJM cnsiders the AVR t be in-service/autmatic mde and regulating vltage. c. When an SVC is cnnected t the grid, PJM cnsiders the SVC t be in autmatic mde and regulating vltage. 3. Availability: The availability and/r unavailability f a reactive device in full is cmmunicated t PJM thrugh the absence f a PJM edart ticket (availability) r the presence f an edart ticket (unavailability) which identifies the equipment as being unavailable.

PJM will crdinate scheduled utages f all Reprtable Transmissin Facilities with planned generatin utages that are submitted t PJM and may affect PJM RTO peratin. Fr purpses f scheduling, Reprtable Transmissin Facilities include, but are nt limited t, lines, transfrmers, phase angle regulatrs, buses, breakers, discnnects, Bulk Electric System capacitrs, reactrs, and all related equipment. Generatin Owners that wn transmissin equipment such as circuit breakers, capacitr banks, etc., d nt have the capability t submit utage requests n transmissin equipment in edart. As a result, fr Reprtable Transmissin Facilities in each TO zne, the Generatin Owner must ntify the affected Transmissin Owner wh must then submit utage requests t PJM via edart fr this generatin-wned equipment as sn as practical after they are infrmed f the utage. It is the respnsibility f the Generatin Owner t keep the Transmissin Owner updated n the status f this equipment and any assciated utage requests. PJM maintains a list f Reprtable Transmissin Facilities. Each Transmissin Owner submits the tentative dates f all transmissin utages f Reprtable Transmissin Facilities t PJM as far in advance as pssible. Prcedures and timelines are established fr the scheduling, crdinating, requesting, studying, apprving, and ntifying f the transmissin utage t/by the apprpriate Transmissin Owner and PJM. The prcedures and timelines are identified in this sectin and are peridically reviewed and revised. Under certain cnditins such as extreme weather, peak lad, heightened hmeland security, etc., PJM will evaluate the need t perate the Pwer Grid in a mre cnservative manner. Actins that may be taken in these special circumstances include, but are nt limited t, canceling by Transmissin Owner, denying by PJM, r rescheduling utages and returning utaged equipment t service.

(Refer Sectin fr On time transmissin utage submissin requirements). Under certain circumstances, it may be beneficial t investigate the pssibility f mving r accelerating a transmissin facility utage if shrtening the verall utage time r mving the start/stp dates can alleviate transmissin cngestin r revenue inadequacy. T accmmdate utages that may be accelerated under this prcess, PJM will review all utages exceeding 5 days in duratin submitted by the Transmissin Owners under the 6 mnth requirement as utlined abve and frced utages prjected t last int the mnth f the analysis windw. This analysis will begin n the first f the mnth 60 days in advance f the utage start dates. If such utage meets the criteria as utlined in the next sectin it may be psted fr acceleratin under this prcess. If transmissin facility utage acceleratin is pssible, the csts incurred by the Transmissin Owner in accelerating the utage will be paid by the PJM Member(s) wh request the utage acceleratin. T accmmdate a request fr the Transmissin Owner t mve r accelerate an utage, additinal csts such as vertime, weekend/hliday, r cntractr csts may be incurred.

The Transmissin Owner wuld fllw Gd Utility Practice, applicable OSHA standards, as well as any and all cmpany safety prtcls in determining whether t mve r accelerate an utage and by hw much, and wuld als cnsider any restrictins/requirements cntained in cllective bargaining agreements Criteria fr Outage Acceleratin Outages that qualify fr this prcess include the planned utages that will exceed five days and are estimated t cause mre than $500,000 in cngestin revenue inadequacy. Als qualifying fr this prcess are frced utages prjected t last int the mnth f the analysis windw and are estimated t cause mre than $500,000 in cngestin revenue inadequacy. These utages will be psted t the PJM OASIS apprximately fur weeks prir t the FTR auctin perid that wuld include the utage. Planned utages affecting the intercnnectin f a generating unit t the transmissin system qualify fr utage acceleratin regardless f expected cngestin revenue inadequacy. Nte: Outages that directly affect a generatr s cnnectin t the transmissin system will NOT be psted n OASIS because they may reveal the future status f a generating unit Timelines fr the Outage Acceleratin Prcess PJM will start reviewing all utages exceeding five days 2 mnths befre the first f the mnth in which the utages are scheduled t begin. Outages that meet the acceleratin criteria will be psted n OASIS by the 15 th f the mnth. Market participants have 1 week t express willingness t accelerate an utage. The Transmissin Owner then has 1 week t prvide a gd faith estimate fr acceleratin. Market participants can express willingness t accelerate r reschedule utages that affect the intercnnectin f a generating unit at any time up t tw weeks prir t the utages scheduled start date. The Transmissin Owner then has ne week frm the request t prvide a gd faith estimate fr acceleratin Prcessing Transmissin Outage Acceleratin Requests Participants must make a request fr acceleratin f an utage within ne week f the utage being psted. Fr an utage affecting the intercnnectin f a generating unit, participants must make a request fr acceleratin up t tw weeks prir t the utage s scheduled start date. If ne r mre requests are received t accelerate an utage, PJM will cntact the Transmissin Owner and request a revised schedule and cst estimate t accelerate. PJM shall nt reveal the identity f the Market Participant(s) making such request(s) t the Transmissin Owner. The Transmissin Owner will prvide PJM with a respnse that the utage can r cannt be accelerated within ne week f the ntificatin by PJM. If the utage can be accelerated the Transmissin Owner will prvide an updated schedule that either mves the utage r shrtens the duratin f the utage alng with the assciated csts fr acceleratin. Either ptin shuld result in a prjected reductin f revenue inadequacy caused by the utage. Once the estimate is received frm the Transmissin Owner, PJM will cntact the participant(s) that made a request t accelerate the utage and prvide them with the details f the estimate. If nly ne participant has made a request, that ne participant can decide whether t accelerate r nt and is then slely respnsible fr the actual Transmissin Owner s acceleratin csts.

Based n the ttal amunt the participants are willing t pay t accelerate, PJM wuld make a determinatin whether t mve frward with the acceleratin. Once it is decided t mve frward with the acceleratin the Transmissin Owner shall update edart with the new utage schedule. Determinatin wuld be made based n PJM judgment if the cmmitted acceleratin request amunts exceed the estimate by a sufficient margin. As a general guideline, fr utages utside f a plant r substatin, this margin shuld be a multiple f 2 times the Transmissin Owner s estimate fr transmissin utages. Fr utages inside the plant, the margin shuld be a multiple f 5. Nte: Inside a substatin refers t the substatin equipment (including the measurement and metering equipment) t the pint f intercnnectin t the EHV netwrk. The intercnnectin pint may be within the physical limits f the substatin perimeter. 1. Actual csts t accelerate wuld be divided pr-rata acrss the participants wh requested the acceleratin, based n the amunt they prvided with the request. 2. PJM shall give participants nly ne chance t make a request t accelerate an utage. Meaning, if after the first rund f requests there is nt enugh mney t accelerate the utage, the utage wuld nt be accelerated. 3. Participants wuld nly be able t submit an ffer fr the acceleratin quted by the TO. Fr example, if the TO says it will cst $50,000 t reduce a tw week utage t ne week, participants cannt request t accelerate nly t 10 days. Revisin: 52, Effective Date: 12/22/2017 PJM

All f the financial risks assciated with the utage acceleratin will be brne by thse market participants wh chse t participate in the specific utage acceleratin; the Transmissin Owner will nt be respnsible fr any f these additinal csts. If, despite the gd faith effrts f the Transmissin Owner, the acceleratin estimated is exceeded, r the Transmissin Owner is nt able t successfully cmplete the utage n the accelerated schedule, the market participants will bear the full cst f the acceleratin. It shall be the respnsibility f the Transmissin Owner t make every reasnable effrt t cntact PJM prir t exceeding the riginal estimate by 20% f the cst t accelerate t determine if wrk shuld cntinue at the accelerated schedule r be cmpleted at the riginal schedule.

87 Attachment B: Transmissin Outage Cut-In Ticket Guidelines Attachment B: Transmissin Outage Cut-In Ticket Guidelines The fllwing guidelines have been created in rder t assist the Transmissin Owner (TO) in determining if the cut-in flag shuld be checked when submitting a transmissin utage ticket in edart. It is critical that this flag be used as intended t ensure all new and/r upgraded facilities/equipment are being accurately mnitred and screened fr in the PJM EMS. This attachment will include the high-level criteria fr the cut-in tickets, fllwed by sme descriptive examples f tickets that shuld have the cut-in bx checked as well as sme that shuld nt have the cut-in bx checked. It shuld be nted, there may be sme exceptins and situatins that d nt fit entirely int the criteria belw. In thse instances, please cntact PJM Transmissin Operatins Department fr clarificatin. Cut-In Criteria fr TO A. All cut-in tickets shuld have a very explicit descriptin f wrk. (i.e., At the cmpletin f this utage, new line xx-xx will be energized ). This is especially imprtant s all PJM users f edart can have a clear picture f what equipment/facilities need t be updated in the PJM EMS. B. When pssible, future equipment shuld be included in the cut-in ticket if already in the PJM mdel. If new equipment is nt available in edart, descriptin f wrk cmments shuld include this infrmatin s PJM staff can enter the new equipment nce it is mdeled. C. There shuld nly be ne cut-in ticket per facility being energized. The assumptin is, at the return f the ticket, the cut-in facility will be in service. Other tickets that supprt the cnstructin f the final energized facility (i.e., utages supprting intermediate phases f cnstructin) shuld NOT be marked cut-in. In such cases, it is preferred that each ticket indicate which ne is the final cut-in ticket (i.e. ticket 1 f 2, final cut-in ccurs n edart #999999) D. PJM cut-in tickets generally DO fall int ne f the fllwing categries: 1. Any new branch (line, transfrmer, series device, phase shifter) r shunt that will affect PJM mdeled tplgy. 2. Any recnfiguratin (circuit breakers, discnnects, bus tplgy changes) 3. Any recnductred/upgraded equipment that will result in a different rating and/r impedance change when re-energized (i.e., CT/PT, wave trap) 4. Permanently retiring facilities (shuld be explicitly nted in descriptin f wrk) E. PJM cut-in tickets generally DO NOT fall int the fllwing categries: 1. Replace/repair existing equipment that will nt change ratings r tplgy (i.e., CT/PT, wave trap, distributin transfrmer) 2. Ples/twers, fundatins, any preparatin wrk r sequence f tickets related t energizatin that will NOT result in energizatin at the cmpletin f that specific ticket (NOTE: cause type New Cnstructin shuld be used fr this, nt Cut-In ). Examples where cut-in flag is apprpriate As described in sectin A abve, new line energizatin with explicit descriptin f wrk Revisin: 52, Effective Date: 12/22/2017 PJM

88 Attachment B: Transmissin Outage Cut-In Ticket Guidelines As described in sectin D (2), tickets that invlve bus recnfiguratins shuld be marked as cut-in. Typically, these invlve new CBs and cntingency changes. Each ticket is fr energizatin f a different piece f equipment related t the new transfrmer (CB s). The last ticket is t energize the transfrmer. Nte that the actual transfrmer is NOT n any f the preceding tickets because it will nt be in service nce they are cmplete. Examples where cut-in flag is NOT apprpriate As described in C abve, the fllwing tw tickets were submitted fr the same facility and with identical descriptins, yet bth were marked as cut-in. If final facility energizatin ccurs n 3/21, then Ticket A shuld NOT be marked cut-in. Revisin: 52, Effective Date: 12/22/2017 PJM
