Description

Information, link

Information to be published before the annual yearly capacity auction

29 (a)

Information for standard capacity products for firm capacity (reserve prices, multipliers, seasonal factors, etc.)

Information is available in the decision No. 119 of the Public Utilities Commission (PUC) Council regarding the natural gas transmission service tariffs of the joint-stock company 'Conexus Baltic Grid', dated October 26, 2023.

(1) Standard capacity product tariffs: Transmission tariffs

(2) Article 13 of Regulation 2017/460 stipulates the range of multipliers applicable to standard capacity products. The multipliers used in the tariff calculation are calculated according to the level set out in the first paragraph of Article 13 of Regulation 2017/460. In order to avoid undue competition between entry points of the common natural gas market, thus improving natural gas trade in the common natural gas market and optimising natural gas flows between Finland, Estonia and Latvia, the same multipliers shall be applied to entry points of the common natural gas market. Taking this into account, as well as in accordance with Article 28(3) of Regulation 2017/460, the following multipliers are applied during setting of tariffs for short-term capacity products:

(3) According to Article 15 of Regulation 2017/460, the seasonal factor applies in such cases when standard capacity products are not offered with a constant capacity for a year. In accordance with Article 28(3) of Regulation 2017/460, a seasonal factor of 1.0 is to be applied in the calculation of tariffs, taking into account the different level of natural gas market development within the common natural gas market. The seasonal factor is 1.0, meaning that it does not lead to seasonal tariff differentiation.

29 (b)

Information for standard capacity products for interruptible capacity (reserve prices and an assessment of the probability of interruption)

(1) Interruptible capacity product tariffs: Transmission tariffs

(2) Discount of 5% is applied for interruptible capacity products according to Methodology for calculation of tariffs for natural gas transmission system service.

30 (1) (b) (ii)

The information related to changes in the revenue referred to in point from one year to the next year

30 (1) (b) (iii)

Information about the following parameters: (1) types of assets included in the regulated asset base and their aggregated value; (2) cost of capital and its calculation methodology; (3) capital expenditures, including:

(a) methodologies to determine the initial value of the assets; (b) methodologies to reevaluate the assets; (c) explanations of the evolution of the value of the assets; (d) depreciation periods and amounts per asset type. (4) operational expenditures; (5) incentive mechanisms and efficiency targets; (6) inflation indices.

(1) Types of assets included into regulated asset base according to Methodology for calculation of tariffs for natural gas transmission system service (methodology only in Latvian)

I. Intangible assets;

II. Fixed assets (land, buildings; technological equipment; other fixed assets);

III. Payments accounted in assets for participation in the international transmission infrastructure establishment projects;

IV. Liabilities, arising from decisions regarding distribution of investment costs, which were adopted in accordance with the Regulation (EU) No 347/2013 of the European Parliament and of the Council of 17 April 2013 on guidelines for trans-European energy infrastructure and repealing Decision No 1364/2006/EC and amending Regulations (EC) No 713/2009, (EC) No 714/2009 and (EC) No 715/2009. In the calculation of regulatory asset base (hereinafter - RAB) the following items are excluded: financial investments, trade accounts payable, securities and capital shares, monetary funds, inventories, assets not yet accepted into use (construction in progress), as well as part of the value of fixed assets which was co-financed by the state, local government, European Union or other international organization and institution's financial aid or support. RAB does not include changes in the value of assets created by other parties or changes in their value resulting from revaluation.

RAB value for the Tariff period is 221 853.2 thousand EUR.

2. According to Methodology for calculation of tariffs for natural gas transmission system service (methodology only in Latvian) the cost of capital composes depreciation and return on capital. The return on capital is calculated by multiplying the RAB value by the weighted average cost of capital rate (WACC rate), taking into account the duration of the Tariff period (12 months).

The real WACC rate in the Tariff period is 2.72%, according to the Public Utilities Commission (PUC) decision No. 177 “On the rate of return on capital for the calculation of a tariff project for the natural gas transmission system, natural gas distribution system and natural gas storage services” (only in Latvian).

(3) Capital expenditure:

a)methodology to determine the initial value of the assets – assets are carried at their cost of acquisition;

b) methodology to re-evaluate the assets – The last revaluation of fixed assets was carried out in 2020. The revaluation was performed by independent certified appraisers to determine the value: initial value, accumulated depreciation and residual value for each group of fixed assets. Method used in the revaluation was based on the average construction and acquisition costs in Latvia. According to Methodology for calculation of tariffs for natural gas transmission system service, starting from December 31, 2021, the capital costs (or RAB value) does not include changes in the value of assets resulting from revaluation.

 c) explanation of the evolution of the value of the assets – depreciation is applied on a straight-line basis over the useful life of asset;

d) depreciation periods (according to Appendix 3 of the Methodology for calculation of tariffs for natural gas transmission system service) and depreciation amounts per asset type in Tariff period:

(4) Operational expenditures in Tariff period – 17 194.0 thosuand EUR.

(5) Incentive mechanisms and efficiency targets – the costs of capacity booking services during the Tariff period need to be reduced for operational efficiency: 358.2 thousand EUR

(6) Inflation indices:

30 (1) (b) (iv, v)

(iv) Information about the transmission services revenue; (v) the following ratios for the revenue referred to in point (iv): (1) capacity-commodity split; (2) entry-exit split; (3) intra-system/cross-system split.

(iv) Tariff period revenue:

(1) Capacity-based revenue 100% (a+b+c);

(2) Entry revenue 11% (a) / Exit revenue 89% (b+c);

(3) Intra-system revenue 93% (a+c)/ Cross-system revenue 7% (b).

30 (1) (b) (vi)

Information related to the previous tariff period regarding to reconciliation of the regulatory account: (1) the actually obtained revenue, the under- or over[1]recovery of the allowed revenue and the part thereof attributed to the regulatory account and, if applicable, sub-accounts within such regulatory account;

(2) the reconciliation period and the incentive mechanisms implemented

(1) The difference between the actual revenue/costs and the allowed revenue/costs during the previous tariff period (01.12.2023–30.09.2025) results in a negative balance of EUR 9 434.7 thousand, of which EUR 6 698.6 thousand is included in the allowed revenue for the next tariff period (01.10.2025–30.09.2026), thereby increasing it

2) In the previous tariff period, incentive mechanisms for reconciliation were not used.

Not applicable

30 (2) (a)

Information on transmission tariff changes/trends

1. Yearly standard capacity product tariffs, short-term standard capacity product tariffs, interruptible capacity product tariffs and interruptible virtual counter flow capacity product tariffs for the natural gas transmission system do not be changed in the regulatory period (01.12.2023-30.09.2026): Transmission tariffs
2. Changes of charge for the use of the exit point for supplying gas users in Latvia:

For the tariff period from 01.10.2025 to 30.09.2026, the fee for using the exit point for supplying Latvian users was increased by 21%, taking into account a negative revenue adjustment for the tariff period from 01.12.2023 to 30.09.2025, which resulted from lower revenues due to reduced natural gas consumption.
