Finnish, Estonian and Latvian TSOs of

Baltic CCR TSOs’ Common Methodology for Splitting Long-Term Cross-Zonal

Capacity in Accordance with Article 16 of Commission Regulation (EU) 2016/1719 of

26 September 2016 Establishing a Guideline on Forward Capacity Allocation

October 2025

Whereas

(1) This document by Finnish, Estonian and Latvian Transmission System Operators of Baltic Capacity

Calculation Region (hereafter referred to as “Baltic CCR”) as defined in accordance with Article 15 of

Commission Regulation (EU) 2015/1222 establishing a guideline on Capacity Allocation and

Congestion Management (hereafter referred to as the “CACM Regulation”) describes a common

Methodology for Splitting Long-Term Cross-Zonal Capacity (hereafter referred to as the “LTCS”) in

accordance with Article 16 of the Commission Regulation 2016/1719 (hereafter referred to as the “FCA

Regulation).

(2) This LTCS takes into account the general principles, goals and other methodologies set in the FCA

Regulation, CACM Regulation, Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing

a Guideline on Electricity Transmission System Operation (hereafter referred to as "SO Regulation"),

and Regulation 2019/943 of the European Parliament and of the Council of 5 June 2019 on the internal

market for electricity (hereafter referred to as “Regulation No 2019/943”).

(3) The goal of the FCA Regulation is the coordination and harmonisation of cross-zonal capacity

calculation and capacity allocation in the forward markets, and it sets requirements for the TSOs to

cooperate on the level of capacity calculation regions (hereinafter referred to as “CCRs”), on a pan-

European level and across bidding zone borders. The FCA Regulation also sets rules for establishing

capacity calculation methodologies based either on the coordinated net transmission capacity approach

(hereafter referred to as “CNTC approach”) or on the flow-based approach (hereafter referred to as “FB

approach”). In case of the TSO(s) allocating long term transmissions rights (hereinafter referred to as

“LTTRs”), the FCA Regulation also sets rules for establishing a methodology for the splitting of long

term capacity on different time frames, e.g. month and year.

(4) This LTCS fulfills the requirement of Article 16(2)(a) of the FCA Regulation as it ensures the

availability of LTTRs for market participants at least for the yearly and monthly timeframes.

(5) This LTCS fulfills the requirement of Artice 16(2)(b) by taking into account the Capacity Calculation

Methodology developed in accordance with Article 10 of the FCA Regulation (hereinafter „Long-term

CCM“), and approved pursuant to Article 4(7)(a) of FCA Regulation, thereby being coherent with the

said methodology.

(6) This LTCS fulfills the requirement of Article 16(2)(c) as it ensures that yearly capacity shall not be

allocated for the entire volume in the yearly auction in order to allow market participants to cover their

hedging needs at least on yearly and monthly timeframes and thus allowing the market participant to

access hedging opportunities in both timeframes. Further, this LTCS does not lead to restrictions in

competition, in particular for access to long-term transmission rights, as the splitted long-term cross-

zonal capacity is allocated in public auctions.

(7) Article 4(8) of the FCA Regulation requires that the expected impact of the LTCS on the objectives

of the FCA Regulation is described. The impact is presented below (points (8) to (12) of this Whereas

Section).

(8) The LTCS contributes to and does not in any way hamper the achievement of the objectives of

Article 3 of the FCA Regulation. In particular, the LTCS serves the objectives of optimising the

calculation and allocation of long-term transmission rights (Article 3(b) of the FCA Regulation),

providing non-discriminatory access to long-term transmission rights (Article 3(c) of the FCA

Regulation), respecting the need for a fair and orderly forward capacity allocation and orderly price

formation (Article 3(e) of the FCA Regulation), ensuring and enhancing the transparency and reliability

of information on forward capacity allocation (Article 3(f) of the FCA Regulation) and contributing to

the efficient long-term operation and development of the electricity transmission system and electricity

sector in the Union (Article 3(g) of the FCA Regulation).

3

(9) The LTCS serves the objective of optimising the calculation and allocation of long-term transmission

rights in accordance with Article 3(b) of the FCA Regulation by using the Long-term CCM of the Baltic

CCR for calculating the available long-term cross-zonal capacities and using these values as a point of

departure for determining the capacities provided for the purpose of allocating LTTRs.

(10) The LTCS provides non-discriminatory access to LTTRs (Article 3(c) of the FCA Regulation) as

there are no barriers for access to the auction of LTTRs if the conditions, cf. the Harmonised Allocations

Rules, are fulfilled. Moreover it ensures fair and nondiscriminatory treatment of TSOs, the Agency,

regulatory authorities and market participants (Article 3(d) of the FCA Regulation) as the rules provide

no undue discrimination for market participants and allows for access to data by the Agency regulatory

authorities and market participants.

(11) The LTCS contributes to the objective of respecting the need for a fair and orderly forward capacity

allocation and price formation (Article 3(e) of the FCA Regulation) by making available in due time the

cross-zonal capacity to be released in the long-term time frame and forward markets, where appropriate.

(12) The LTCS serves the objective of transparency and reliability of information (Article 3(f) of the

FCA Regulation) as the LTCS determines the main principles and main processes for allocating LTTRs.

The LTCS enables Baltic CCR TSOs to provide market participants with the same reliable information

on cross-zonal capacities and allocation constraints for long-term allocation and forecasting purposes in

a transparent way. To facilitate transparency, Baltic CCR TSOs will publish data to the market on a

regular basis to help market participants to evaluate the LTTR process and long-term capacity forecasts.

Baltic CCR TSOs will engage stakeholders in dialogue to specify necessary hedging needs to this effect.

(13) The LTCS does not hinder an efficient long-term operation in Baltic CCR and adjacent CCRs, and

the development of the transmission system in the European Union (Article 3(g) of the FCA Regulation).

The LTCS serves the objective of efficient long-term operation and development of the electricity

transmission system and electricity sector in the European Union (Article 3 (g) of the FCA Regulation)

by taking into account the Long – term CCM developed in accordance with Article 10 of the FCA

Regulation and approved pursuant to Article 4(7)(a) of FCA Regulation when determining the capacities

for the purpose of allocating LTTRs, and by contributing to the hedging opportunities of the market

participants.

(14) In conclusion, the methodology for splitting rules contributes to the general objectives of the FCA

Regulation to the benefit of market participants and electricity end consumers.

(15) The calculation of the LTTR volumes on the Finland–Estonia bidding zone border takes into

account the technical capabilities of the two HVDC interconnectors (i.e. ESTLINK 1 and ESTLINK 2)

of this border by limiting the volumes of the FI-EE LTTRs to reflect the maximum physical flow of

electricity in a situation where only one interconnector is in use. Initially, the TSOs active on this border

considered it feasible to limit the sum of yearly and monthly LTTRs to 650 MW, which corresponds to

the maximum physical electricity flow hosted by the larger of the two interconnectors (i.e. ESTLINK

2).

2. THE PROPOSAL AND PROCESS

The NRAs have conducted a thorough and coordinated assessment of the amended

LTCS Proposal. Having assessed the amended LTCS proposal, the NRAs came to the

conclusion that even though the amendments are largely in line with the request for

amendments, there still are some places to improve. As a result, the NRAs decided to

revise parts of the LTCS Proposal before the approval, in accordance with Article 5(6)

of Regulation 2019/942 and Article 4(5) of the Regulation 2016/1719. On 23 September

2025, the NRAs sent a letter to the TSOs’ representatives to consult the TSOs on the

planned revisions to the methodology and to provide their opinion on the proposed

corrections within 14 calendar days. On 25 September 2025 the TSOs informed that

they have reviewed the NRAs proposal and find it fully acceptable.

3. NRAS’ REVISIONS ON THE AMENDED LTCS PROPOSAL

NRAs decided to revise the LTCS Proposal by making the following changes:

(Added corrections are marked in red and removed parts are crossed out.)

Whereas (13):

(13) The LTCS does not hinder an efficient long-term operation in Baltic CCR and

adjacent CCRs, and the development of the transmission system in the European

Union (Article 3(g) of the FCA Regulation). The LTCS serves the objective of efficient

long-term operation and development of the electricity transmission system and

electricity sector in the European Union (Article 3 (g) of the FCA Regulation) by

taking into account Long – term CCM developed in accordance with Article 10 of the

FCA Regulation and approved pursuant to Article 4(7)(a) of FCA Regulation when

determining the capacities for the purpose of allocating LTTRs, and by contributing to

the hedging opportunities of the market participants.

Whereas (15):

(15) The calculation of the LTTR volumes on the Finland–Estonia bidding zone border

takes into account the technical capabilities of the two HVDC interconnectors (i.e.

ESTLINK 1 and ESTLINK 2) of this border by limiting the volumes of the FI-EE

LTTRs to reflect the maximum physical flow of electricity in a situation where only

one interconnector is in use. Initially, the TSOs active on this border considered it

feasible to limit the sum of yearly and monthly LTTRs to 650 MW, which corresponds

to the maximum physical electricity flow hosted by the larger of the two

interconnectors (i.e. ESTLINK 2). Due to procedural reasons, this approach is still

maintained in this proposal although the concerned TSOs after the launch of the public

consultation of this proposal identified a clear need to limit the sum of the yearly and

monthly FI-EE LTTR volumes to reflect the actual observed technical capability of the

interconnectors. Therefore, following the submission of this current proposal, the

concerned TSOs are planning to submit a new proposal in near future to take into

account this obtained new information. In the new proposal, the concerned TSOs will

7

propose a change that is expected to primarily alleviate the impacts of the observed

underselling of the FI-EE LTTRs, thus preventing a transfer of wealth from tariff

payers to traders.

Soome, Eesti ja Läti põhivõrguettevõtjate metoodika, vastavalt Komisjoni määruse (EL)

2016/1719, millega kehtestatakse võimsuse jaotamise forvardturu eeskiri, artikli 16

lõikele 1, kooskõlastamise kohta

1. Haldusmenetluse alustamine

Euroopa Komisjoni määrusega (EL) 2016/1719 kehtestati võimsuse jaotamise forvardturu

eeskiri (edaspidi ka FCA või FCA määrus)1.

FCA artikli 4 lõike 1 alusel töötavad põhivõrguettevõtjad välja FCA määrusega nõutud

tingimused ja meetodid ning esitavad need heakskiitmiseks koostööametile2 või pädevatele

reguleerivatele asutustele vastavalt FCA määruses sätestatud tähtaegadele. Erandlikel

asjaoludel, eelkõige juhul, kui tähtajast ei ole võimalik kinni pidada põhivõrguettevõtjatest

sõltumatute asjaolude tõttu, võib lõike 6 kohaste menetluste puhul tingimuste või meetodite

tähtaegu pikenda koostööamet ning lõike 7 kohaste menetluste puhul võivad seda teha kõik

pädevad reguleerivad asutused ühiselt. Kui käesoleva määruse kohase tingimuste või meetodite

kehtestamise ettepaneku väljatöötamises ja kokkuleppimises peab osalema rohkem kui üks

põhivõrguettevõtja, peavad osalevad põhivõrguettevõtjad tegema tihedat koostööd.

Põhivõrguettevõtjad peavad koostöös Euroopa elektri põhivõrguettevõtjate võrgustikuga

korrapäraselt teavitama pädevaid reguleerivaid asutusi ja koostööametit nimetatud tingimuste

või meetodite väljatöötamise edenemisest.

FCA artikli 4 lõike 5 järgi vastutab iga reguleeriv asutus või vajaduse korral koostööamet artikli

4 lõigetes 6 ja 7 osutatud tingimuste või meetodite heakskiitmise eest. Enne tingimuste ja

meetodite heakskiitmist vaatavad koostööamet või pädevad reguleerivad asutused pärast

asjaomaste põhivõrguettevõtjatega konsulteerimist vajaduse korral ettepanekud läbi, et tagada

nende kooskõla käesoleva määruse eesmärgiga ning aidata kaasa turgude lõimimisele,

mittediskrimineerimisele, tõhusale konkurentsile ja turu nõuetekohasele toimimisele.

FCA artikli 4 lõike 7 punkti b) alusel peab piirkonnaülese võimsuse jaotamise metoodika

kooskõlas FCA artikliga 16 saama kõigi asjaomase piirkonna reguleerivate asutuste heakskiidu.

FCA artikli 4 lõike 9 järgi, kui tingimuste või meetodite heakskiitmiseks vastavalt lõikele 7 või

nende muutmiseks vastavalt lõikele 11 on vaja rohkem kui ühe reguleeriva asutuse otsust,

peavad pädevad reguleerivad asutused kokkuleppele jõudmiseks omavahel konsulteerima,

tegema tihedat koostööd ja kooskõlastama oma tegevuse. Vajaduse korral võtavad pädevad

reguleerivad asutused arvesse koostööameti arvamust. Reguleerivad asutused või vajaduse

korral koostööamet teevad lõigete 6 ja 7 kohaselt esitatud tingimuste ja meetodite kohta otsuse

kuue kuu jooksul alates sellest, kui koostööamet või asjakohasel juhul viimane asjaomane

reguleeriv asutus on tingimused või meetodid kätte saanud. Ajavahemik algab järgmisel päeval

pärast seda, kui ettepanek esitati koostööametile vastavalt lõikele 6 või viimasele asjaomasele

reguleerivale asutusele vastavalt lõikele 7.

FCA artikli 4 lõike 11 alusel, kui koostööamet või kõik pädevad reguleerivad asutused ühiselt

nõuavad lõigete 6 ja 7 kohaselt esitatud tingimuste või meetodite muutmist enne nende

heakskiitmist, peavad asjaomased põhivõrguettevõtjad esitama muudetud tingimuste või

meetodite ettepaneku heakskiitmiseks kahe kuu jooksul alates koostööameti või reguleerivate

asutuste sellekohase taotluse esitamisest. Koostööamet või pädevad reguleerivad asutused

teevad muudetud tingimuste või meetodite kohta otsuse kahe kuu jooksul pärast nende

esitamist. Kui pädevad reguleerivad asutused ei ole jõudnud kokkuleppele lõikes 7 osutatud

tingimuste või meetodite osas kahe kuu pikkuse tähtaja jooksul või nende ühise taotluse korral

või koostööameti taotlusel vastavalt määruse (EL) 2019/942 artikli 5 lõike 3 kolmandale

lõigule, võtab koostööamet kuue kuu jooksul vastavalt määruse (EL) 2019/942 artikli 5 lõikele

3 ja artikli 6 lõike 10 teisele lõigule vastu otsuse muudetud tingimuste või meetodite kohta. Kui

asjaomased põhivõrguettevõtjad ei esita tingimuste või meetodite muutmise ettepanekut,

kohaldatakse lõikes 4 kirjeldatud menetlust.

FCA artikli 4 lõike 13 alusel FCA määruse kohaste tingimuste ja meetodite väljatöötamise eest

vastutavad põhivõrguettevõtjad avaldavad need tingimused ja meetodid internetis pärast nende

heakskiitmist ameti või pädevate reguleerivate asutuste poolt, või kui heakskiitu ei ole vaja, siis

pärast nende tingimuste ja meetodite väljatöötamist, välja arvatud juhul, kui selline teave on

artikli 7 kohaselt konfidentsiaalne.

FCA artikli 16 lõike 1 järgi peavad iga võimsusarvutuse ala põhivõrguettevõtjad, hiljemalt

artiklis 10 sätestatud võimsuse arvutamise metoodika esitamise ajaks, välja töötama metoodika

ettepaneku piirkonnaülese võimsuse jagamiseks pikkade ajavahemike korral koordineeritud

viisil erinevates võimsuse jaotamise ajavahemikes vastavas piirkonnas. Ettepaneku üle tuleb

pidada konsultatsioone kooskõlas artikliga 6.

FCA artikli 16 lõike 2 järgi peab piirkonnaülese võimsuse jagamise meetod pikkade

ajavahemike korral vastama järgmistele tingimustele:

a) see peab vastama turuosaliste riskimaandamise vajadustele;

b) see peab olema kooskõlas võimsuse arvutamise metoodikaga;

c) see ei tohi kaasa tuua konkurentsi piiranguid, eelkõige seoses juurdepääsuga pikaajalistele

ülekandeõigustele.

3. Asjaolud ja menetluse käik

06.02.2025 esitas Elering AS (edaspidi Elering) Konkurentsiametile kooskõlastamiseks

Soome, Eesti ja Läti põhivõrguettevõtjate (edaspidi ka põhivõrguettevõtjad) ühise metoodika

ettepaneku piirkonnaülese võimsuse jagamiseks pikkade ajavahemike korral koordineeritud

viisil erinevates võimsuse jaotamise ajavahemikes Balti koordineeritud võimsusarvutuse alas,

kooskõlas FCA artikli 16 lõikega 1 (metoodika). Viimane asjaomane riiklik reguleeriv asutus4

sai metoodika ettepaneku kätte 18.02.2025.

Põhivõrguettevõtjad on kooskõlas FCA artikliga 6 metoodika ettepanekut koos selgitava

dokumendiga ENTSO-E konsultatsioonikeskkonnas perioodil 14.11.2024 kuni 13.12.2024.5

19.06.2025 jõudsid kõik asjaomased riiklikud reguleerivad asutused kokkuleppele taotleda

metoodika ettepaneku muutmist FCA artikli 4 lõike 11 alusel. Kooskõlas FCA artikli 4 lõikega

9 konsulteerisid asjaomased riiklikud reguleerivad asutused omavahel, tegid tihedat koostööd

ja kooskõlastasid oma tegevust, et jõuda metoodika kooskõlastamise asjus kokkuleppele.

19.06.2025 edastas Konkurentsiamet Eleringile kirja muudatusnõuete kohta.

19.08.2025 esitas Elering Konkurentsiametile muudetud metoodika ettepaneku, mis oli ühiselt

heakskiidetud asjaomaste põhivõrguettevõtjate poolt. Viimane asjaomane riiklik reguleeriv

asutus sai metoodika ettepaneku kätte 20.08.2025.

4 Antud metoodika puhul asjaomasteks riiklikeks reguleerivateks asutusteks on Eesti, Läti ja Soome riiklikud

reguleerivad asutused. 5 Kättesaadav: https://consultations.entsoe.eu/markets/pfa-of-baltic-ccr-tsos-common-methodology/

23.09.2025 konsulteerisid asjaomased riiklikud reguleerivad asutused põhivõrguettevõtjatega

e-kirja vahendusel muudetud kujul metoodika ettepanekut. Eelnimetatud muudatused

käsitlevad muuhulgas täpsustust FCA määruse artikli 3 punkti g eesmärgi täitmise osas ning

põhimõtte eemaldamist, mis sätestaks aluse ja eelheakskiidu tulevase metoodikamuudatuse

jaoks. Detailsemalt on muudatuste sisu välja toodud asjaomaste riiklike reguleerivate asutuste

ühise seisukoha punktis 3 (Lisa 2).

07.10.2025 kiitsid asjaomased riiklikud reguleerivad asutused ühiselt põhivõrguettevõtjate

metoodika ettepaneku muudetud kujul (Lisa 1) heaks (Lisa 2).

4. Asjaomaste reguleerivate asutuste ühine seisukoht

Asjaomased riiklikud reguleerivad asutused on hinnanud põhivõrguettevõtjate esitatud

metoodika ettepanekut ning otsustasid enne metoodika ettepaneku kooskõlastamist muuta

metoodikat, FCA artikli 4 lõike 5 ja ACERi määruse artikli 5 lõike 6 alusel, et tagada metoodika

ettepaneku kooskõla FCA määrusega. Asjaomaste riiklike reguleerivate asutuste tehtud

muudatused metoodika ettepanekus puudutavad muuhulgas täpsustust FCA määruse artikli 3

punkti g eesmärgi täitmise osas ning põhimõtte eemaldamist, mis sätestaks aluse ja

eelheakskiidu tulevase metoodikamuudatuse jaoks. Detailsemalt on muudatuste sisu välja

toodud asjaomaste riiklike reguleerivate asutuste ühise seisukoha punktis 3 (Lisa 2).

Kokkuvõte

Konkurentsiamet töötas läbi 19.08.2025 Eleringi poolt ametile kooskõlastamiseks esitatud

Soome, Eesti ja Läti põhivõrguettevõtjate ühise metoodika ettepaneku piirkonnaülese võimsuse

jagamiseks pikkade ajavahemike korral koordineeritud viisil erinevates võimsuse jaotamise

ajavahemikes Balti koordineeritud võimsusarvutuse alas, kooskõlas FCA artikli 16 lõikega 1,

ning asub seisukohale, et pärast asjaomaste riiklike reguleerivate asutuste ühiselt sisse viidud

muudatusi, arvestab nimetatud dokument kehtivast seadusandlusest tulenevate alusetega ning

ei ole vastuolus FCAst tuleneva regulatsiooniga.

FCA artikli 4 lõike 13 alusel FCA määruse kohaste tingimuste ja meetodite väljatöötamise eest

vastutavad põhivõrguettevõtjad avaldavad need tingimused ja meetodid internetis pärast nende

heakskiitmist ameti või pädevate reguleerivate asutuste poolt, või kui heakskiitu ei ole vaja, siis

pärast nende tingimuste ja meetodite väljatöötamist, välja arvatud juhul, kui selline teave on

artikli 7 kohaselt konfidentsiaalne.

Arvestades eeltoodut ja tuginedes FCA artikli 4 lõikele 7 punktile b)

otsustan:

kooskõlastada Soome, Eesti ja Läti põhivõrguettevõtjate ühise metoodika ettepaneku

piirkonnaülese võimsuse jagamiseks pikkade ajavahemike korral koordineeritud viisil

erinevates võimsuse jaotamise ajavahemikes Balti koordineeritud võimsusarvutuse alas,

kooskõlas Komisjoni määruse (EL) 2016/1719, 26. september 2016, millega kehtestatakse

võimsuse jaotamise forvardturu eeskiri, artikli 16 lõikega 1, vastavalt käesoleva otsuse lisale 1.

Käesoleva otsusega mittenõustumise korral on õigus esitada kaebus otsuse tühistamiseks

Tallinna Halduskohtule. Kaebuse halduskohtule võib esitada 30 päeva jooksul arvates

käesoleva otsuse teatavaks tegemisest.
