3 TSOs which intend t calculate Scheduled Exchanges resulting frm single day-ahead cupling, taking int accunt the fllwing: Whereas 1. This dcument is a cmmn prpsal develped by the Transmissin System Operatrs (hereafter referred t as TSOs ), which intend t calculate Scheduled Exchanges resulting frm single day-ahead cupling. The dcument prvides a high-level methdlgy fr calculating Scheduled Exchanges resulting frm the single day-ahead cupling ( hereafter referred t as DA Scheduled Exchanges Calculatin Methdlgy ) in accrdance with Article 43 f Cmmissin Regulatin (EU) 2015/1222 establishing a guideline n Capacity Allcatin and Cngestin Management (hereafter referred t as Regulatin 2015/1222 ). This prpsal is hereafter referred t as DA Scheduled Exchanges Calculatin Methdlgy Prpsal. 2. The DA Scheduled Exchanges Calculatin Methdlgy Prpsal, in line with Article 45 f Regulatin 2015/1222, accmmdates situatins where there are mre than ne Nminated Electricity Market Operatr (hereafter referred t as NEMO ) designated and/r ffering dayahead trading services in a particular gegraphic area. In additin, accrding t Article 4(1) f Regulatin 2015/1222, multiple NEMOs can be designated t perfrm single day-ahead cupling in a Member State. Fr each NEMO, a NEMO Trading Hub shall be defined. Where multiple NEMOs perate within a gegraphic area, there shall be multiple NEMO Trading Hubs within that gegraphic area. 3. The DA Scheduled Exchanges Calculatin Methdlgy Prpsal takes int accunt the general principles, gals and ther methdlgies reflected in Regulatin 2015/1222. The gal f Regulatin 2015/1222 is the crdinatin and harmnisatin f capacity calculatin and allcatin in the day-ahead and intraday crss-brder markets. 4. The DA Scheduled Exchanges Calculatin Methdlgy Prpsal recgnises that there are tw ptins available fr the prductin f Scheduled Exchanges: i. In line with current practice fr sme TSOs, allcated capacities in the frm f allcated flws int and ut f individual relevant DC netwrk elements (perated in DC mde) and allcated capacities in the frm f allcated flws n relevant Bidding Zne brders shall be prduced as an utput f the day-ahead market cupling algrithm. These allcated capacities shall be validated by particular TSOs and used as the Scheduled Exchanges resulting frm the single day-ahead cupling fr that market time unit. ii. In line with current practice fr sme TSOs, allcated capacities in the frm f allcated flws int and ut f individual relevant DC netwrk elements (perated in DC mde) and allcated capacities in the frm f allcated flws n relevant Bidding Zne brders (difference in flws in/ut reflecting lsses where applicable) shall be prduced as an utput f the day-ahead market cupling. These allcated capacities shall be used as an input int the Scheduled Exchange calculatin by the Scheduled Exchange Calculatr(s). 3

4 This DA Scheduled Exchanges Calculatin Methdlgy Prpsal prvides the cmmn methdlgy framewrk fr the prductin f Scheduled Exchanges by the Scheduled Exchange Calculatr(s). Accrding t Article 43 f the Regulatin 2015/1222, this is a methdlgy fr calculating scheduled exchanges resulting frm single day-ahead cupling. Accrding t Article 2(32), a scheduled exchange means an electricity transfer scheduled between gegraphic areas, fr each market time unit and fr a given directin. This DA Scheduled Exchanges Calculatin Methdlgy Prpsal als prvides fr the calculatin f Scheduled Exchanges per NEMO Trading Hub. While a NEMO Trading Hub cannt be interpreted as a gegraphic area, the calculatin f Scheduled Exchanges per NEMO Trading Hub is essential in rder t accmmdate multi-nemo arrangements within Bidding Znes and Scheduling Areas. 5. The DA Scheduled Exchanges Calculatin Methdlgy shall serve as a cmmn high level calculatin methdlgy t be applied by the Scheduled Exchange Calculatr(s) wh shall be respnsible fr the calculatin f Scheduled Exchanges resulting frm single day-ahead cupling as per Article 49 f Regulatin 2015/ The DA Scheduled Exchanges Calculatin Methdlgy Prpsal shall cnsider situatins where the Bidding Zne is equal t the Scheduling Area, as well as where there are multiple Scheduling Areas within a Bidding Zne. 7. Net psitins and prices are fixed by the results frm the single day-ahead cupling. Furthermre, crss znal capacities and allcatin cnstraints have already been taken int accunt by the market cupling algrithm. Crss znal capacities and allcatin cnstraints shall therefre nt be impacted by the calculated scheduled exchanges nr the Scheduling Restrictins. Scheduling Restrictins may include: i. Priritisatin Path: the priritisatin f a given path amng all pssible paths t transfer a net psitin frm a surce area t a sink area; ii. Shrtest Path: the minimisatin f a number f areas invlved in transferring a net psitin frm a surce area t a sink area; iii. Intuitiveness: the requirement that net psitins are always transferred frm lw price areas t high price areas. 8. Accrding t Article 9(9) f Regulatin 2015/1222, the prpsed timescale fr the implementatin f the prpsed DA Scheduled Exchanges Calculatin Methdlgy shall be included and can be fund in Article 8 f the DA Scheduled Exchanges Calculatin Methdlgy Prpsal. 9. The Cngestin Incme Distributin Methdlgy prvided accrding t Article 73 f the Regulatin 2015/1222, ntes that when calculating the Cngestin Incme per Bidding Zne brder, Scheduled Exchanges may be required as an input. Where allcated capacities (in the frm f allcated flws) are used by TSOs instead f carrying ut the Scheduled Exchange Calculatin, these allcated capacities shall be used as Scheduled Exchanges. 4

5 10. This DA Scheduled Exchanges Calculatin Methdlgy describes the current situatin regarding bth the use f allcated capacities as Scheduled Exchanges and the calculatin f Scheduled Exchanges by All TSOs. This DA Scheduled Exchange Methdlgy may require amendment based n further implementatin f all prcesses related t the single day-ahead cupling but shall at least be reviewed by TSOs applying Scheduled Exchanges n later than tw years after the apprval by the regulatry authrities f the cncerned regin as per Article 46(4) f Regulatin 2015/ Accrding t Article 9(9) f Regulatin 2015/1222, the expected impact f the prpsed DA Scheduled Exchanges Calculatin Methdlgy, n the bjectives f Regulatin 2015/1222, shall be described. Article 3(a) f Regulatin 2015/1222 aims at prmting effective cmpetitin in the generatin, trading and supply f electricity.

Article 3(e) f Regulatin 2015/1222 aims at ensuring fair and nn-discriminatry treatment f TSOs, NEMOs, the Agency, regulatry authrities and market participants. The DA Scheduled Exchanges Calculatin Methdlgy shall be fair, transparent and based n the results f single day-ahead cupling. Additinally, where required under certain market settlement regimes, the calculatin may be perfrmed at NEMO Trading Hub level, in rder t allw the recnciliatin f Scheduled Exchanges per NEMO and therefre facilitating multi-nemo scenaris in such cntexts. Article 3(f) f Regulatin 2015/1222 aims at ensuring and enhancing the transparency and reliability f infrmatin. The DA Scheduled Exchanges Calculatin Methdlgy cmprises a step-wise, tp-dwn apprach (frm Bidding Zne, t Scheduling Area, t NEMO Trading Hub) fr the calculatin f Scheduled Exchanges which ensures and enhances the transparency and reliability f the DA Scheduled Exchanges Calculatin Methdlgy. Article 3(g) f Regulatin 2015/1222 aims at cntributing t the efficient lng-term peratin and develpment f the electricity transmissin system and electricity sectr in the Unin. The DA Scheduled Exchanges Calculatin Methdlgy shws clear crss- Netwrk Cde thinking in rder t cntribute t the efficient develpment f a single day-ahead electricity market in Eurpe. The DA Scheduled Exchanges Calculatin Methdlgy, thrugh its cnstructin cmprising f bilateral scheduled exchanges, as well as multilateral scheduled exchanges, facilitates the efficient lng-term peratin and develpment f the Eurpean transmissin system. Article 3(h) f Regulatin 2015/1222 aims at respecting the need fr a fair and rderly market and fair and rderly price frmatin. The DA Scheduled Exchanges Calculatin Methdlgy des nt interfere with r cmprmise the annymity f the market participants as it has n influence n the results f single day-ahead cupling. Article 3(i) f Regulatin 2015/1222 aims at creating a level playing field fr NEMOs. The DA Scheduled Exchanges Calculatin Methdlgy creates a level playing field fr NEMOs as it has n influence n the results f single day-ahead cupling. Additinally, the DA Scheduled Exchanges Calculatin Methdlgy supprts scenaris where there are multiple NEMOs within a Bidding Zne r Scheduling Area. 6

The Scheduled Exchange Calculatr(s) shall ntify the results f the DA Scheduled Exchanges Calculatin t relevant NEMOs, central cunter parties, shipping agents and TSOs within 15 minutes after delivery f the infrmatin listed in Article 3 by the relevant NEMOs. The results f the Scheduled Exchange Calculatr(s) shall be (fr each market time unit): Bilateral Scheduled Exchanges per DC netwrk element, per Scheduling Area brder, per Bidding Zne brder and between NEMO Trading Hubs; Multilateral Scheduled Exchanges 2 per Scheduling Area, per Bidding Zne and per NEMO Trading Hub. Article 5 General Principles fr Calculatin f Scheduled Exchanges The Scheduled Exchange Calculatr(s) shall, n request f TSOs which intend t calculate Scheduled Exchanges, calculate the Scheduled Exchanges n the relevant Bidding Zne r Scheduling Areas brders and between NEMO Trading Hubs accrding t the fllwing principles: Scheduled Exchanges already validated by relevant TSOs n nn-relevant 3 Bidding Zne r Scheduling Areas brders and between NEMO Trading Hubs shall nt be impacted by the DA Scheduled Exchanges Calculatin. A Bilateral Scheduled Exchange fr a given DC netwrk element, Scheduling Area brder, Bidding Zne brder, r between NEMO Trading Hubs shall nly be calculated by the designated Scheduled Exchange Calculatr. The calculatin f Scheduled Exchanges shall be carried ut by the Scheduled Exchange Calculatr(s) such that the cnstraints described in Article 5, Article 6 and Article 7 f this DA Scheduled Exchanges Calculatin Methdlgy prpsal are respected. Where relevant, Scheduled Exchange Calculatrs shall crdinate t ensure that the specific implementatin f the methdlgy they apply respectively fulfils this principle. The DA Scheduled Exchanges Calculatin as described in Article 6 and Article 7 shall respect the net psitin f the Scheduling Area, Bidding Zne and NEMO Trading Hub and allcated capacities, bth in the frm f allcated flws n DC netwrk elements (perated in DC mde) and in the frm f allcated flws n relevant Bidding Zne brders (difference in flws in/ut reflecting lsses where applicable) resulting frm the single day-ahead cupling. Scheduled Exchanges acrss a Bidding Zne brder, where ne Bidding Zne has multiple Scheduling Areas, shall be cnsistent i.e. the Scheduled Exchanges shall be calculated by a designated Scheduled Exchange Calculatr and the sum f the Scheduled Exchanges n the Scheduling Area brders crrespnding t this Bidding Zne brder shall equal the Scheduled Exchange n this Bidding Zne brder. 2 Multilateral Exchanges d nt include DC netwrk element exchanges as DC netwrk element exchanges are nt relevant fr calculatin f the Lad Frequency Cntrller set-pint. 3 Nn-relevant refers t thse brders which shall nt use the DA Scheduled Exchanges Calculatin Methdlgy as per Article 43 f Regulatin 2015/

11 When applicable, the relevant TSOs which intend t calculate Scheduled Exchanges resulting frm single day-ahead cupling shall identify t the Scheduled Exchange Calculatr(s) all relevant cnstraints cnsidered fr allcatin and pssible additinal Scheduling Restrictins. Any additinal Scheduling Restrictins shall be justified by the relevant TSOs and cmmunicated in a transparent way t relevant stakehlders. Article 6 - Methdlgy fr calculating Scheduled Exchanges between Scheduling Areas, Bidding Znes and NEMO Trading Hubs resulting frm single day-ahead cupling The Scheduled Exchange Calculatr shall, n request f the relevant TSOs, calculate the Scheduled Exchanges accrding t the calculatin set frth belw. This calculatin shall respect the Scheduling Restrictins defined in Article 5 and shall be perfrmed per market time unit: 1. The Scheduled Exchange Calculatr shall derive the SEC Net Psitin within a CCR frm the available input fr each Bidding Zne, Scheduling Area and NEMO Trading Hub as per Article 3 f this DA Scheduled Exchange Methdlgy prpsal. The SEC Net Psitin within a CCR shall equal the ttal vlume f Scheduled Exchanges n relevant brders fr which the Scheduled Exchange Calculatr shall calculate the Scheduled Exchanges. The calculatin shall respect and be cmpliant with the TSOs using the allcated capacities in the frm f allcated flws n nn-relevant brders. 2. The Scheduled Exchange Calculatr shall calculate the Bilateral Scheduled Exchanges between the Bidding Znes f the CCR using the Bidding Zne SEC Net Psitin within a CCR. This calculatin shall then ptimise the Scheduled Exchanges between the Bidding Znes accrding t the defined Scheduling Restrictins. 3. The calculatin f the Bilateral Scheduled Exchanges between Scheduling Areas f the CCR shall fllw the principles described in Article The calculatin f Bilateral Scheduled Exchanges between NEMO Trading Hubs f the CCR shall fllw the principles described in Article Scheduled Exchanges shall always be calculated fr a specific directin i.e. scheduled exchange frm / t. 6. Finally, if requested by the relevant TSOs, the Scheduled Exchange Calculatr shall calculate the Multilateral Scheduled Exchange per Bidding Zne, Scheduling Area and NEMO Trading Hub by aggregatin f the relevant Bilateral Scheduled Exchanges. Article 7 Calculatin f Scheduled Exchanges per CCR The DA Scheduled Exchanges Calculatin Methdlgy, in accrdance with Article 43 f Regulatin 2015/1222, shall be based n a step-wise DA Scheduled Exchanges Calculatin as described in Article 6. This sectin gives an verview f the calculatin methdlgy which the Scheduled Exchange Calculatr shall apply t derive the SEC Net Psitin f a Bidding Zne r Scheduling Area r NEMO Trading Hub within a particular CCR. Article 7.1 Calculatin f input parameters: the SEC net psitins within a CCR Fr each Bidding Zne, Scheduling Area and NEMO Trading Hub within a particular CCR, the Scheduled Exchange Calculatr shall derive the SEC Net Psitin. The SEC Net Psitin f a Bidding Zne r Scheduling Area r a NEMO Trading Hub within a particular CCR shall be used as an input value fr the 11

12 calculatin f Scheduled Exchanges. The SEC Net Psitin f a Bidding Zne, Scheduling Area r a NEMO Trading Hub within a particular CCR shall equal the ttal vlume f scheduled exchanges calculated by the respective Scheduled Exchange Calculatr. The Scheduled Exchange Calculatr(s) shall calculate the different SEC Net Psitins within a CCR accrding t the principles defined belw: 1. The Bidding Zne SEC Net Psitin within a CCR is determined by the net psitin f the Bidding Zne reduced by the allcated capacities in the frm f allcated flws f all Bidding Zne brders nt being part f this CCR, as prvided by the relevant NEMOs. 2. The Scheduling Area SEC Net Psitin within a CCR is determined prprtinally t the rati between: the crrespnding Bidding Zne SEC Net Psitin within this CCR the crrespnding Bidding Zne Net Psitin. Equatin 1 SEC NP SA /CCR j = NP SA SEC NP BZ/CCR j NP BZ SEC NP SA /CCR j = Scheduling Area SEC Net Psitin within a CCR j NP SA = Net Psitin f the Scheduling Area SEC NP BZ /CCR j = Bidding Zne SEC Net Psitin within a CCR j NP BZ = Net Psitin f the Bidding Zne When multiple Scheduling Areas exist within ne Bidding Zne then, this calculatin shall respect the Bidding Zne SEC Net Psitin within a CCR, i.e. the sum f Scheduling Area SEC Net Psitin within a CCR shall be equal t the Bidding Zne SEC Net Psitin within a CCR If there is nly ne Scheduling Area within the Bidding Zne, then the Scheduling Area SEC Net Psitin within a CCR and the Bidding Zne SEC Net Psitin shall be equal. 3. Ntwithstanding the specific cases where there are efficiency gains which can be achieved by priritising Scheduled Exchanges between the same NEMOs ver Bidding Zne r Scheduling Area brders, the NEMO Trading Hub SEC Net Psitin within a CCR is determined prprtinally t the rati between: the crrespnding Bidding Zne r Scheduling Area SEC Net Psitin within this CCR the crrespnding Bidding Zne r Scheduling Area Net Psitin. The calculatin f a NEMO Trading Hub SEC Net Psitin within a CCR n a Bidding Zne r Scheduling Area level can be described by the fllwing frmulas: 12

13 Equatin 2 SEC NP NTH /CCR j = NP NTH SEC NP BZ/CCR j NP BZ SEC NP NTH /CCR j = NEMO Trading Hub SEC Net Psitin within a CCR j NP NTH = Net Psitin f the NEMO Trading Hub SEC NP BZ /CCR j = Bidding Zne SEC Net Psitin within a CCR j Equatin 3 NP BZ = Net Psitin f the Bidding Zne SEC NP NTH /CCR j = NP NTH SEC NP SA/CCR j NP SA SEC NP NTH /CCR j = NEMO Trading Hub SEC Net Psitin within a CCR j NP NTH = Net Psitin f the NEMO Trading Hub SEC NP BZ /CCR j = Scheduling Area SEC Net Psitin within a CCR j NP BZ = Net Psitin f the Scheduling Area The calculatin f the different SEC Net Psitins within a CCR can be described by the frmula belw: Equatin 4 SEC NP/CCR j = SCHEX OUTf m SEC NP/CCR j = Scheduled Exchange Calculatr Net Psitin f a Bidding Zne, Scheduling Area r NEMO Trading Hub within a particular CCR j n m=1 m = Variable representing individual Bidding Znes, Scheduling Areas r Nem Trading Hubs m n which have brders with Bidding Zne, Scheduling Area r NEMO Trading Hub (f) and fr which TSOs intend t calculate Scheduled Exchanges n = Ttal Number f Bidding Znes, Scheduling Area r NEMO Trading Hubs which have brders with Bidding Zne, Scheduling Area r NEMO Trading Hub (f) and fr which TSOs intend t calculate Scheduled Exchanges SCHEX OUTf = Scheduled Exchanges per Bidding Zne brder r Scheduling Area brder r between NEMO Trading Hubs, m m n which TSOs intend t calculate using the Scheduled Exchange Calculatr. Article 7.2 Calculatin f Scheduled Exchanges between Bidding Znes After the SEC Net Psitin f a Bidding Zne/Scheduling Area r a NEMO Trading Hub within a particular CCR has been determined, the Scheduled Exchange Calculatr shall calculate the Scheduled Exchanges between the Bidding Znes f the CCR using the Bidding Zne SEC Net Psitin within a 13

14 CCR. This calculatin shall ptimise the Scheduled Exchanges between the Bidding Znes accrding t Scheduling Restrictins defined per CCR. The calculatin prblem shall be defined in such a way that cngestin incme distributin as described in the Cngestin Incme Distributin Methdlgy prvided accrding t Article 73 f the Regulatin 2015/1222 is nt impacted. When cnsidering the Crdinated Net Transmissin Capacity (hereafter referred t as CNTC ) Apprach, where a price difference exists between tw Bidding Znes either the available capacity has been fully used r anther allcatin cnstraint (e.g. ramping cnstraint) was active. Hence, if there is a price difference between tw Bidding Znes, within a CCR applying CNTC, the Scheduled Exchanges shall be equal t the allcated capacity. The ptimisatin f the Scheduled Exchanges shall aim t minimise the Scheduled Exchanges between the invlved Bidding Znes. Fr this minimisatin, the Scheduled Exchanges within the CCR fr which TSOs intend t calculate Scheduled Exchanges (BSE calc ) shall be used as a set f variables t minimise the target functin while respecting the defined cnstraints, Scheduling Restrictins and the scheduled exchanges n the nn-relevant brders 4. Equatin 5 minimise Target Functin(BSE calc ), s that BSE calc respects the cnstraints Fr this target functin, the Scheduled Exchanges shall be multiplied by a set f linear and quadratic cst cefficients. Equatin 6 Target Functin(BSE calc ) 2 = ( BSE calc Linear Cst Cefficient + BSE calc Quadratic Cst Cefficient) The summatin takes int accunt all Scheduled Exchanges within the CCR fr which TSOs intend t calculate Scheduled Exchanges (BSE calc ). The definitin f the cst cefficients used in the target functin shuld be dependent n the Scheduling Restrictins defined within the CCR e.g. the applicatin f the priritisatin path wuld mean that the cst cefficients fr certain Bidding Zne Brders differ frm the thers s that the rules impsed by the CCRs are met by the target functin. Furthermre, the linear cst cefficients culd be set t ne and the quadratic cst cefficients culd be set t zer s that nly the ttal sum f Scheduled Exchanges, fr which the TSO intend t perfrm the calculatin, is minimised. The cnstraints defining the ptimisatin prblem include the requirements elabrated in the beginning f this Article 7. The calculated BSE calc shuld be cnsistent with the SEC net psitins within a CCR. 4 nn-relevant brders are the brders fr which the Scheduled Exchanges are nt calculated accrding t the apprach defined by Article 43 f Regulatin 2015/1222 but the allcated capacities are prvided by the relevant NEMOs 14

Equatin 7 (Price BZ B Price BZ A ) Bilateral Exchange A B 0 Article 7.3 Calculatin f Scheduled Exchanges between Scheduling Areas In general, there is nly ne Scheduling Area per Bidding Zne. Where there is nly ne Scheduling Area per Bidding Zne, the Scheduled Exchanges between tw Bidding Znes equal the Scheduled Exchanges between the tw Scheduling Areas. Hwever, a specific case can exist: If there is mre than ne Scheduling Area within a Bidding Zne then: a. The Scheduled Exchange Calculatr(s) shall calculate the Scheduled Exchanges between the Scheduling Areas f the CCR using the Scheduling Area SEC Net Psitin within a CCR. This calculatin shall ptimise the Scheduled Exchanges between the Scheduling Areas accrding t Scheduling Restrictins defined per CCR. Fr this calculatin, a similar ptimisatin prblem shall be defined as fr the Bilateral Exchanges between Bidding Znes with additinal requirement described in pint b. b. If there are multiple Scheduling Areas n ne (r bth) side(s) f the Bidding Zne Brder, then the Scheduled Exchanges between the Scheduling Areas, ver the Bidding Zne Brder, shall be attributed t each Scheduling Area Brder prprtinally t the installed thermal capacity f the intercnnectins. Article 7.4 Calculatin f Scheduled Exchanges between NEMO Trading Hubs After the calculatin f the Scheduled Exchanges between Bidding Znes and Scheduling Areas within the CCR, the Scheduled Exchanges between the NEMO Trading Hubs can be calculated. These Scheduled Exchanges shall be calculated s that they respect the afrementined Scheduled Exchanges. Therefre, tw main principles have been determined: 1. The NEMO Trading Hub SEC Net Psitin within a CCR shall be settled prprtinally within a Bidding Zne r Scheduling Area, depending if Bidding Zne equals Scheduling Area r if multiple Scheduling Areas exist within the Bidding Zne. This implies that if there are multiple NEMOs within a Bidding Zne / Scheduling Area, the NEMOs with the same sign f NEMO Trading Hub SEC Net Psitin within a CCR (i.e. a NEMO Trading Hub has a psitive net psitin (exprting) within a Bidding Zne with a psitive net psitin (exprting)) shall first schedule an exchange with each f the NEMOs with an ppsite sign t the NEMO Trading Hub SEC Net Psitin within a CCR. This exchange shuld be prprtinal t the NEMO Trading Hubs cntributin t the Bidding Zne s SEC Net Psitin within a CCR r the Scheduling Area s SEC Net Psitin within a CCR. The crss brder Scheduled Exchanges between NEMOs f the CCR shall respect the Scheduled Exchanges calculated between the Bidding Znes and Scheduling Areas f the CCR and shall priritise Scheduled Exchanges between the same NEMOs ver Bidding Zne r Scheduling Area brders. 15

16 Article 8 - Implementatin date The DA Scheduled Exchanges Calculatin Methdlgy is currently implemented by a subset f TSOs. Accrding t Article 43(4) f the Regulatin 2015/1222, n later than tw years after apprval by the regulatry authrities, the TSOs applying Scheduled Exchanges shall review the DA Scheduled Exchanges Calculatin Methdlgy. In additin, further implementatin f all prcesses related t the single dayahead cupling may result in amendments t this methdlgy. Article 9 - Language The reference language fr this DA Scheduled Exchanges Calculatin Methdlgy Prpsal shall be English. Fr the avidance f dubt, where TSOs need t translate this DA Scheduled Exchanges Calculatin Methdlgy Prpsal int their natinal language(s), in the event f incnsistencies between the English versin published by TSOs in accrdance with Article 9(14) f the Regulatin 2015/1222 and any versin in anther language, the relevant TSOs shall be bliged t dispel any incnsistencies by prviding a revised translatin f this DA Scheduled Exchanges Calculatin Methdlgy Prpsal t their relevant natinal regulatry authrities. 16
