That is, the ttal amunt f the charges equals the ttal amunt f the credits; there are n residual funds. With certain exceptins, each f the services als perates n a balanced basis. That is, the charges and credits fr a particular service, such as regulatin, ffset each ther exactly. In certain cases, charges in excess f credits, r vice versa, in ne service are used t ffset the csts f prviding anther service. 1.2 Accunting Input Data At the end f each perating hur, PJM cllects infrmatin regarding actual peratins during the hur. This infrmatin is recrded either by the PJM dispatchers r by autmated systems. The market accunting prcesses use this infrmatin as input data. Other accunting input data is prvided frm varius systems and databases. This infrmatin includes data describing PJM Members installed generating resurces, scheduling infrmatin fr PJM Members transactins, and Transmissin System parameters, such as lss factrs determined annually by PJM system planning staff.

14 PJM Manual 28: Operating Agreement Accunting Sectin 1A: Revenue Data fr Settlements Sectin 1A: Revenue Data fr Settlements Welcme t the Revenue Data fr Settlements sectin f the PJM Manual fr Operating Agreement Accunting. In this sectin, yu will find the fllwing infrmatin: A descriptin f settlement interval data fr the day-ahead and real-time energy markets. An verview f hw revenue data submitted by market participants is used in the settlement calculatins further described in this manual. 1A.1 Business Rules fr Revenue Data fr Settlements PJM settles the Day-ahead Energy Market n an hurly basis and the Real-time Energy Market n a five-minute basis. T reflect these tw distinct timeframes, PJM refers t the term Dayahead Settlement Interval thrughut this manual t mean the interval used t settle day-ahead transactins, which shall be every ne clck hur. In additin, PJM refers t the term Realtime Settlement Interval thrughut this manual t mean the interval used t settle real-time transactins, which shall be every five minutes. Revenue Data fr Settlements are real-time energy quantities used fr accunting and billing and are determined based n data submitted by a Market Participant. Generatr MW data can be submitted by a Market Participant int Pwer Meter as either five-minute revenue meter data r hurly revenue meter data. The business rules fr electing t submit five minute revenue meter data are specified in Sectin 3 f this PJM Manual. Revenue Data fr Settlements fr generatin resurces submitting five-minute revenue meter data is the submitted value fr each Real-Time Settlement Interval (five minute interval). Once a Market Participant submits five minute revenue meter data fr a resurce, the Market Participant must cntinue t prvide revenue meter data fr that resurce n a five minute basis and cannt switch t hurly revenue meter data submissins. If wnership f a resurce is transferred between Market Participants and prir t the transfer the resurce is submitting five minute revenue meter data, the new wner f the resurce must cntinue t prvide revenue meter data n a five minute basis. Revenue Data fr Settlements fr generatin resurces submitting hurly revenue meter data shall be determined by the fllwing prcess: Fr each five minute interval, PJM calculates a time-weighted telemetry MW value and a State Estimatr MW value. A time-weighted telemetry MW value is determined based n the prrated time duratin that a telemetry MW value is effective ver each five minute interval. Where n = number f telemetry values in a five minute interval Revisin: 79, Effective Date: 04/01/2018 PJM

15 PJM Manual 28: Operating Agreement Accunting Sectin 1A: Revenue Data fr Settlements Fr each hur f the perating day, PJM calculates an hurly-integrated telemetry MWh value using the time-weighted telemetry MW values fr each f the five minute intervals in the hur Where n = number f real-time settlement intervals in an hur Time-weighted State Estimatr MW value is determined based n the prrated time duratin that a State Estimatr MW value is effective ver each five minute interval Where n = number f SE values in a five minute interval Fr each hur f the perating day, PJM calculates an hurly-integrated State Estimatr MWh value using the time-weighted State Estimatr MW values fr each f the five minute intervals in the hur Where n = number f real-time settlement intervals in an hur T determine whether time-weighted Telemetry r time-weighted State Estimatr MW values is used t calculate the Revenue Data fr Settlements fr each five minute interval in an hur, PJM selects the lesser f: the abslute value difference between the Hurly Revenue Meter MWh and the Hurly Integrated Telemetry MWh and the abslute value difference between the Hurly Revenue Meter MWh and the Hurly Integrated State Estimatr MWh C= lesser f (A and B) Where A = Hurly Revenue Meter MWh Hurly Integrated Telemetry MWh B = Hurly Revenue Meter MWh - Hurly Integrated State Estimatr MWh If A and B are equal, the time-weighted Telemetry MW values are used t calculate the Revenue Data fr Settlements fr each five minute interval in an hur. A tlerance check is perfrmed t ensure the selected time-weighted MW values are within a tlerance fr settlement accuracy. If the time-weighted Telemetry MW values are used t calculate the Revenue Data frm Settlements, then the fllwing check is perfrmed: Revisin: 79, Effective Date: 04/01/2018 PJM

16 PJM Manual 28: Operating Agreement Accunting Sectin 1A: Revenue Data fr Settlements If the abslute value f the difference between the Hurly Integrated Telemetry MWh and the Hurly Revenue Meter MWh value is greater than 20 percent and greater than 10 MWh, then the Revenue Data fr Settlements fr each f the Real-time Settlement Intervals f the hur will be flat-prfiled and set equal t the Hurly Revenue Meter MWh. AND If the time-weighted State Estimatr MW values are used t calculate the Revenue Data frm Settlements, then the fllwing check is perfrmed: If the abslute value f the difference between the Hurly Integrated State Estimatr MWh and the Hurly Revenue Meter MWh value is greater than 20 percent and greater than 10 MWh, then the Revenue Data fr Settlements fr each f the Realtime Settlement Intervals f the hur will be flat-prfiled and set equal t the Hurly Revenue Meter MWh. AND The Revenue Data fr Settlements fr each five minute interval in an hur is calculated as fllws:. If C is equal t A, then

17 PJM Manual 28: Operating Agreement Accunting Sectin 1A: Revenue Data fr Settlements Where n = number f real-time settlement intervals in an hur If a Market Participant is unable t prvide telemetry fr a generating resurce, the Revenue Data fr Settlements fr each f the five minute intervals f the hur is equal t the hurly revenue meter MWh value. Fr all energy transactins fr which telemetry is nt available, the Revenue Data fr Settlements is equal t the MW value fr the five minute intervals that the energy transactin is dispatched r scheduled. Fr Demand Respnse resurces, Revenue Data fr Settlements is equal t the revenue meter MW data submitted by the Market Participant fr the five minute intervals that the resurce is dispatched. A Demand Respnse resurce can submit either hurly r five minute lad reductin data. Fr lad, the Revenue Data fr Settlements fr each f the five minute intervals f the hur is equal t the hurly submitted MWh value. Revisin: 79, Effective Date: 04/01/2018 PJM

A Market Participant s Day-ahead spt market energy psitin is determined fr each hurly interval and is equal t the sum f a market participant s demand and decrement bids cleared in the day-ahead market, less any accepted generatin and increment ffers cleared in the dayahead market, and is adjusted fr all day-ahead energy transactins in which the custmer accunt is invlved. Fr each five minute interval, PJM calculates each market participant s real-time spt market energy psitin based n energy injectins and withdrawals. A Market Participant s Real-time spt market energy psitin is determined fr each five minute interval and cnsists f a market participant s metered tie line flws (if applicable),less any wnership f metered generatin, and is adjusted fr all real-time energy transactins (including any lad bligatins [de-rated fr transmissin lsses] r generatin mdeled by InSchedule transactins, and including any InSchedule transactins that were priced day-ahead) in which the custmer accunt is invlved. 3.4 Transmissin Lss De-ratin Factrs Because PJM emplys a Marginal Lss methdlgy, energy market-related settlements need t use lad respnsibilities de-rated fr transmissin lsses. This is due t the fact that the LMPs include a lss price cmpnent. In rder t remve all transmissin lsses, as represented in PJM s netwrk system mdel, hurly EDC lss de-ratin factrs are applied t the ttal EDC lad and t individual LSE lad respnsibilities. In general, these lss deratin factrs represent ttal transmissin lsses divided by ttal lad including lsses. (Nte that these are different frm traditinal lss factrs which reflect ttal lsses divided by lad excluding lsses.) Each hur, PJM calculates a lss de-ratin factr fr each EDC that has their tie lines fully metered directly t PJM. Fr nn-pjm Mid-Atlantic EDCs (that d nt receive an allcatin f the jintly-wned PJM 500 kv transmissin system lsses), the calculatin is as fllws: EDC ttal state-estimated Lss MWh / EDC ttal revenue-metered lad MWh including all lsses Fr PJM Mid-Atlantic EDCs (that d receive an allcatin f the jintly-wned PJM 500 kv transmissin system lsses), the calculatin is as fllws: (EDC ttal state-estimated nn-500kv Lss MWh + EDC revenue-metered 500kV Lss Allcatin MWh) / (EDC ttal revenue-metered lad MWh including all nn-500kv lsses + EDC revenue-metered 500kV Lss Allcatin MWh) These EDC hurly lss de-ratin factrs are applied t the LSE lad respnsibility InSchedule MWh quantities (which are inclusive f all lsses) that are carved-ut f the applicable EDC s ttal lad, as well as applied t any residual lad respnsibility remaining with the EDCs, as fllws: Revisin: 79, Effective Date: 04/01/2018 PJM

The ttal lad actually served at each lad bus is initially determined by the State Estimatr. Fr each Electric Distributin Cmpany (EDC) that reprts hurly net energy flws frm all metered tie lines t PJM via Pwer Meter and revenue meter data fr the net energy delivered by all generatrs within that EDC s territry via Pwer Meter, fr the purpse f energy market accunting the EDC is classified as a fully metered EDC. The ttal fully metered EDC revenuemetered lad is calculated as the sum f the net imprt energy flws reprted by their tie revenue meters plus the net generatin reprted by the generatr revenue meters. The amunt f lad at each f such fully metered EDC s lad buses calculated by the PJM State Estimatr is then adjusted, in prprtin t its share f the ttal lad f that fully metered EDC, in rder that the ttal amunt f lad acrss all f the fully metered EDC s lad buses matches its ttal revenue meter calculated lad. PJM will assess and trend quarterly the degree f net energy injectins at lad buses mdeled in the PJM netwrk system mdel (i.e., reverse pwer flws) in rder t detect and crrect and mdeling issues and t identify any generatin in excess f lad that appears at a lad bus. PJM will determine and use a relevant net energy injectin threshld at a lad bus that may impact LMP and/r lad accuracy. Fr lad buses with persistent negative MWh, PJM will wrk with the applicable EDC t determine if the cause is subptimal mdeling r actual reverse pwer flws frm distributin-level system(s) t the PJM transmissin system, r simply nrmal results due t state estimatin. Prperly mdeled lad buses with cnsistent excess energy injectins due t distributin-level reverse pwer flws shuld be mdeled as generatin buses in the PJM netwrk system mdel at the lad bus lcatin in rder t minimize the amunt f negative MWh bserved at thse lad buses. 3.6 Residual Metered Lad Fr settlements purpses, lad within a fully metered EDC s territry is assigned t nn-metered entities by submitting hurly lad bligatin data in the InSchedule system. Data submitted in the InSchedule system includes the names f the LSE respnsible fr serving the lad and the EDC in whse territry the lad is lcated, the number f megawatts f lad assigned t the LSE fr each hur, the aggregate at which lad is t be priced, and the start and end dates fr the lad cntract. During the settlements prcess, lad assigned t an LSE at a specified aggregate is further assigned t individual lad buses based n the aggregate definitin, which specifies the percentage f the verall aggregate that each bus represents, t identify the LSE s hurly megawatts f lad at each bus. Ndal priced lad is defined as any hurly lad submitted under an InSchedule cntract that is priced at an aggregate cmprised f a single identifiable bus r set f identifiable buses at which the lad is lcated. A detailed descriptin f the ndal pricing settlements business rules can be fund in Manual 27 Sectin 5.6.

Residual metered lad at each bus is defined as the bus lad (adjusted revenue meter calculated lad as calculated in Sectin 3.5) less the ndal priced lad at each bus. 3.7 Residual Metered Lad Aggregate Definitins Residual Metered Lad aggregates mre accurately reflect the cmpsitin f nn-ndal priced lad in fully metered EDC territries. Effective June , Residual Metered Lad aggregates are the default fr which real-time lad is settled if it has nt elected t settle at a ndal lad aggregate. Upn implementatin f residual metered lad pricing n June , physical zne pricing fr real-time lad will n lnger be available. Hurly Residual Metered Lad aggregate distributin factrs are determined by dividing the residual metered lad fr each bus in the fully metered EDC territry by the ttal residual metered lad fr the fully metered EDC territry. Residual Metered Lad aggregate prices are defined by weighting each lad bus LMP by that bus residual metered lad aggregate distributin factr. Fr the majrity f PJM transmissin znes, the EDC territry is the same as the physical transmissin zne. In cases where the fully metered EDC s territry differs frm the physical transmissin zne, residual metered lad aggregates exist fr each fully metered EDC territry within the transmissin zne. Residual Metered Lad aggregate cngestin prices, lss prices, and ttal LMPs are calculated using the Residual Metered Lad aggregate distributin factrs. Factrs fr each Residual Metered Lad aggregate sum t exactly 100%. Hurly Residual Metered Lad aggregate definitins used fr the calculatin f Day-ahead LMPs, preliminary and final Real-time LMPs, and FTRs/ARRs are defined as fllws: Day-ahead Residual Metered Lad aggregate distributin factrs default t the final real-time distributin factrs fr the Residual Metered Lad aggregate at 8:00 a.m. ne week prir t the Operating Day (i.e., if next Operating Day is Mnday, the default distributin is frm 8:00 a.m. n Mnday f the previus week). Cnsistent with physical transmissin znes, the definitin applies t all hurs in the day. Preliminary 5 minute real-time Residual Metered Lad aggregate LMPs are calculated using the same Residual Metered Lad aggregate distributin factrs as used in the Day-ahead market fr the Operating Day. Final hurly real-time Residual Metered Lad aggregate distributin factrs are calculated using InSchedule-submitted ndal lad MWh. Residual Metered Lad aggregate distributin factrs fr ARR/FTR purpses are fixed fr the planning perid (June 1st May 31st). Cnsistent with physical transmissin znes, the residual metered lad aggregate distributins fr FTRs/ARRs are initially determined using the hurly individual residual lad bus cntributin t the ttal residual lad at the time f the previus year s PJM annual peak. In cases where there are new ndal lad requests pursuant t the ndal pricing rules in Manual 27, the initial residual metered lad aggregate definitin fr FTRs/ARRs are adjusted by the LSE s ndal lad peak distributin. LSEs mving t ndal lad settlement fr the upcming PJM planning year will be required t submit a peak lad at the time f the PJM annual peak frm the previus year per the ndal pricing rules in Manual 27. This value in cnjunctin with the distributin percentages currently required accrding t the ndal pricing rules in Manual 27 will be used t determine the final residual metered lad aggregate distributin.

Fr each hurly interval f the perating day, PJM calculates Day-ahead Spt Market Energy charges fr each Market Participant by taking the difference between the sum f the Market Participant s scheduled energy withdrawals times the Day-ahead System Energy Price and the sum f the Market Participant s scheduled energy injectins times the Day-ahead System Energy Price. Market Participant custmer accunts incur +/- charges fr Balancing Spt Market Energy based n deviatins between their real-time energy withdrawals and their day-ahead scheduled energy withdrawals and deviatins between their real-time energy injectins and their dayahead scheduled energy injectins. PJM will take the hurly sum f each Market Participant s scheduled day-ahead energy withdrawals and flat-prfile this value acrss each f the five minute intervals f the hur t btain five minute interval scheduled withdrawals. Day-ahead exprts can be scheduled sub-hurly and are set equal t the MW value fr each f the five minute intervals that the transactin is scheduled in the day-ahead energy market. PJM will take the hurly sum f each Market Participant s scheduled day-ahead energy injectins and flat-prfile this value acrss each f the five minute intervals f the hur t btain five minute interval scheduled injectins. Day-ahead imprts can be scheduled sub hurly and are set equal t the MW value fr each f the five minute intervals that the transactin is scheduled in the day-ahead energy market. Fr each five minute interval f the perating day, PJM calculates Balancing Spt Market Energy charges fr each Market Participant by: Taking the difference between the sum f the Market Participant s real-time five minute energy withdrawals and the day-ahead five minute scheduled energy withdrawals and multiplying this difference by the Real-time five minute System Energy Price divided by 12. This results in a five minute interval withdrawal charge. Taking the difference between the sum f the Market Participant s real-time five minute energy injectins and the day-ahead five minute scheduled energy injectins and multiplying this difference by the Real-time five minute System Energy Price divided by 12. This results in a five minute interval injectin credit. Finally, taking the difference between the five minute interval withdrawal charge and the five minute interval injectin credit.

The recnciliatin kwh data must be supplied t PJM by the EDCs n later than the last day f the billing mnth that is tw mnths after the riginal billing mnth. Fr example, all recnciliatin data fr January must be submitted by March 31 at 23:59. The recnciliatin kwh data represents the difference between the scheduled Retail Lad Respnsibility r Whlesale Lad Respnsibility InSchedule (in MWh) and the actual usage based n metered data. This hurly kwh data must be reprted separately fr each applicable InSchedule cntract. PJM calculates the Spt Market Energy charge recnciliatins by multiplying the kwh data (derated fr transmissin lsses) by the real-time PJM System Energy Price fr that hur. These charge recnciliatins are then ttaled fr the mnth fr each EDC r Retail Lad Aggregatr. Nte that the recnciliatin fr Spt Market charges fr a mnth may be either a psitive r a negative value, and may even be such that the recnciled lad respnsibility MWh results in a negative lad quantity.
