ACER publishes today its report on Lithuania’s proposed gas transmission tariffs.

ACER provides recommendations to the Lithuanian national regulatory authority (NRA), VERT, particularly regarding the existing regional networks and the need to enhance transparency on the proposed asset splits.

What is in the report?

ACER assessed the proposed methodology to calculate the gas tariffs, including:

• The treatment of regional networks;
• The tariffs applicable to the transmission service to the Kaliningrad District; and
• The tariffs applicable to the domestic exit to the Achema fertilizer plant.

What are ACER’s main findings?

ACER recommends to the Lithuanian NRA, VERT, to implement improvements:

• On regional networks, ACER recommends that VERT changes the category of regional networks from transmission to distribution.
• On the asset split applicable for the transmission to Kaliningrad, VERT should provide clarity on the criteria used to establish the asset split.
• On the proposed tariff differentiation to the domestic exit point to the Achema fertilizer plant, ACER recommends specifying the criteria on which a consumer, including Achema, could get a different tariff compared to all other regional network exits.

ACER’s Position Paper towards greater consistency of cost benefit analysis methodologies, published today, identifies topics where consistency is needed across the Cost Benefit Analysis methodologies (CBA methodologies) currently under development by the European Commission and the European electricity and gas grid operators.

Greater consistency of CBA methodologies will enable a more efficient energy system across Europe by ensuring similar terms of assessment of projects in a technology neutral way.

Why did ACER issue this Position Paper?

The updated TEN-E Regulation (Regulation (EU) 2022/869) introduced the task of the development of separate CBA methodologies for the various energy infrastructure categories and by different entities:  

• The EU network of transmission system operators for electricity (ENTSO-E) for electricity transmission projects (including offshore grids);
• The EU network of transmission system operators for gas (ENTSOG)  for hydrogen projects; and
• The European Commission (EC) for projects of energy storage, electricity smart grids, gas smart grids, electrolysers and CO2 networks and facilities.

ACER must provide opinions on the ENTSO-E and ENTSOG CBA methodologies and on the draft lists of PCIs prepared by the EC. The Regulation tasks ACER with promoting consistency in the CBA methodologies developed by the EC with the CBA methodologies elaborated by ENTSO-E and ENTSOG.

To this end, ACER’s Position Paper sets out the topics where consistency should be promoted among all CBA methodologies.

Where is consistency of CBA methodologies needed?

1. Common input data set and assumptions;
2. Selection and use of scenarios and ways to deal with uncertainty;
3. Length of assessment period, residual value of projects, and social discount rate;
4. Definition of reference case networks;
5. Treatment of interdependency with other projects;
6. Project implementation status;
7. Clustering rules;
8. Criteria to assess the plausibility of projects’ commissioning dates;
9. Implementation Guidelines;
10. Definition and handling of capital and operational expenditures;
11. Consideration of the impact of the future extreme weather events on infrastructure resilience;
12. Approach to calculate social and environmental impacts of projects;
13. Methodology to calculate the benefit-to-cost ratio and Net Present Value of projects;
14. Sensitivities;
15. Modelling interlinkages of CBA methodologies;
16. Presentation of CBA results.

Next steps

The ACER Position Paper could serve as a reference document, e.g. during the cooperation with the EC and the ENTSOs during the development phase of their CBA methodologies, as well as when drafting the ACER opinions on the ENTSOs’ CBA methodologies, or when the EC Advisory Board for Climate Change forms their views on the methodologies.

Since 13th January, as required by Council Regulation (EU) 2022/2576, ACER publishes a daily Liquefied Natural Gas (LNG) price assessment. On 8 March, ACER will start applying an updated version (Beta 2.0) of the methodology for its LNG price assessments.

Why update the methodology and why now?

• The aim (as per the Regulation) is for ACER to produce an objective price assessment that reflects the price of LNG spot transactions.
• On some days, there were insufficient eligible LNG spot transactions to calculate the price assessment as per the established methodology (which required a minimum of 5 transactions over 5 rolling days).
• After observing the initial methodology (Beta 1.0) for a few weeks, ACER has decided to update it.
• The Regulation also requires ACER to publish a LNG benchmark by 31 March 2023. ACER intends to start applying the new LNG price methodology as of 8 March in order to verify it until the benchmark’s go-live on 31 March 2023.

What are the main changes to the LNG price assessment methodology and why is it relevant?

• A single EU LNG price will be calculated on top of the current practice of prices for 2 zones (North-West Europe and South Europe).
• ACER’s Beta 1.0 methodology used a 5-day rolling window to aggregate transactions and thus build a price that is representative of the market conditions. Beta 2.0 further shifts the weight of the calculation to the most recent transactions and is at the same time extending the calculation window to 10 days.

This will increase the robustness of the LNG price calculation.

Has ACER consulted stakeholders on its work?

ACER works closely with stakeholders to have a meaningful LNG price assessment that is genuinely representative and not arbitrary. ACER developed and now subsequently refined, with the help of an LNG Expert Group and in consultation with the European Commission, a robust beta methodology underpinning the ACER LNG price assessment.

In addition, ACER intends to further update the Guidance on reporting LNG market data, and improve its TERMINAL platform to improve the user experience. The updated reporting Guidance will mainly clarify important details to assure better data quality. 

Both updated documents will benefit from the advice of its LNG Expert Group, close engagement with market participants (e.g. via roundtables, webinars), input from other stakeholders and ACER price assessors’ experience so far.

Today, ACER publishes its assessment report on the effects of the Market Correction Mechanism (MCM) on energy markets and security of supply.

Background to the MCM

The MCM Regulation (December 2022) establishes a Market Correction Mechanism to protect citizens and the economy against excessively high gas prices. The MCM sets a bidding limit on certain financial derivatives traded at EU exchanges with the aim of limiting EU gas prices. This bidding limit is activated when specific conditions are met.

The Regulation tasks ACER and the European Securities and Markets Authority (ESMA) with assessing the market effects from the introduction of the Market Correction Mechanism (MCM) and submitting their MCM effect assessment reports to the European Commission by 1 March 2023. Both reports are intended to assist the Commission in its decision of extending the MCM to the derivatives traded at other Virtual Trading Points (‘VTPs’) in the EU and in assessing whether the key design elements of the MCM need to be reviewed.  ACER and ESMA already published preliminary reports on 23 January 2023. ESMA also published their final MCM effects assessment report today.

MCM seems not to have a discernible gas market impact to date

Neither ACER nor ESMA have identified significant impacts (positive or negative) that could be unequivocally and directly attributed to the adoption of the MCM.

However, one should not infer from this that the MCM might not have any impacts on financial and energy markets or on security of supply in the future. ACER and ESMA continue to emphasise the need to regularly monitor gas markets and gas trading activities to identify risks and to assist in detecting potential impacts of the MCM in the future.

Challenges of extending the MCM to derivatives linked to other EU Virtual Trading Points (VTPs)

• ACER finds valid arguments for extending the MCM only to VTPs where the liquidity of gas derivative trading is modest to high. ACER considers that the extension of the MCM to other VTPs would not likely lead to significant negative effects in gas markets.
• ACER finds valid arguments for using the same activation and de-activation conditions, making use exclusively of the Dutch TTF front-month price and the same dynamic price-bidding limit at the EU VTPs (where the MCM is extended to other VTPs).

No technical reasons to review the key design elements of the MCM

• ACER could not identify a need for revising the price references used for calculating the reference price.
• ACER could not identify technical reasons to change the current activation or de-activation conditions of the MCM or for changing the dynamic price-bidding limit.

ACER will continue monitoring the effects of the MCM in energy markets and on security of energy supply.

ACER shall adopt a recommendation for identifying good practices for the treatment of investment requests for projects of common interest (PCIs), as tasked by the (2022) Regulation on guidelines for trans-European energy infrastructure.

In light of revised Trans-European Networks for Energy (TEN-E) provisions, and building on the experience gained with latest cross-border cost allocation (CBCA) investment requests, ACER is updating its (2015) CBCA Recommendation.

As part of this process, ACER invites stakeholders to submit their views on the existing CBCA Recommendation, including:

• Scope of ACER CBCA Recommendation;
• Role of scenarios and of cost-benefit analysis in the cross-border cost allocation;
• The allocation and compensation mechanism; and
• Cross-border cost allocation for offshore projects.

The public consultation will run from 23 February until 31 March 2023.

What are the next steps? 

ACER will evaluate the received feedback and take it into consideration when drafting the document.

The updated CBCA Recommendation shall be adopted by 24 June 2023.

ACER publishes today its report on Italy’s proposed gas transmission tariffs. ACER assessed the proposed methodology to calculate the gas transmission tariffs, including:

• The distance cost driver that is used to calculate tariffs in the Italian network;
• The discounts proposed for the exit point to Malta; and
• The proposed application of tariffs for the region of Sardinia.

What are ACER’s main findings?

Whilst acknowledging that the public consultation of the Italian National Regulatory Authority, ARERA, is very well documented and very informative, ACER recommends that ARERA improves:

• The proposed commodity-based tariffs; and
• The proposed approach to setting tariffs in the region of Sardinia.

ACER assesses the proposed methodology to calculate tariffs, including:

• The details on the input parameters to the methodology;
• The regulatory account and the accumulated congestion revenue; and
• The methodology applicable to the L-gas network to transport gas from the Netherlands to France.

What are ACER’s main findings?

The Agency observes that improvements on the proposed transmission tariffs can be achieved based on the provisions of the EU Network Code on Gas Transmission Tariffs and provides some recommendations to the Belgian national regulatory authority CREG.

ACER recommends to CREG to:

• Shorten the duration of the tariff period. This should facilitate the forecast of the contracted capacity, and should help minimise potential under- and over-recoveries as well as the reconciliation of the regulatory accounts.
• Compare (and publish) the forecasted contracted capacity vis-à-vis the realised contracted capacity. This improvement should allow improving the accuracy of the capacity forecast, improve the cost-reflectivity of tariffs and minimises the need to reconcile revenue.
• Ensure the reconciliation of the Transmission System Operator’s (TSO), regulatory accounts, which has accumulated significant over-recoveries, including significant congestion revenue.
• Provide information on the allowed revenue methodology of the TSO, in particular, on the regulatory asset base revaluation of the TSO.
• Provide additional transparency on the cost and the capacity forecast that is used for the calculation of tariffs.

On 22 December 2022, the Council Regulation (EU) 2022/2578 established a gas market correction mechanism (MCM) to protect EU citizens and the economy against excessively high energy prices. It enters into force on 1 February 2023 for a period of one year and tasks ACER with the calculation and publication of the MCM reference price.

Based on the daily collected data, ACER will publish the MCM reference price no later than 23:59 CET every weekday. Find the daily MCM reference price here.

Prices on 1 February 2023 are well under the MCM activation levels.

What is the MCM reference price and how is it calculated?

The MCM reference price is the average price of several Liquefied Natural Gas (LNG) marker prices as assessed by different entities and the front-month National Balancing Point (NBP) derivative settlement price.

In order to calculate the daily MCM reference price, ACER needs the following information:

• The LNG Northwest Europe Marker price assessment;
• The LNG Mediterranean Marker price assessment;
• The LNG Northeast Asia Marker price assessment;
• The front-month NBP derivative settlement price; and
• The price of the ACER’s daily LNG price assessment report.

The values of the three LNG marker price assessments are derived from data administered by Platts Benchmark B.V. and Argus Benchmark Administration B.V. As the MCM reference price is expressed in EUR/MWh, ACER uses European Central Bank’s Euro foreign exchange rates for the currency conversion where needed.   

When is the MCM activated?

According to the Regulation, the MCM can only be activated as of 15 February 2023.

The MCM is activated if the front-month TTF derivative settlement price:

• exceeds 180 EUR/MWh for three consecutive working days, and
• is at least €35 above the MCM reference price for the same period of time.

In the event the MCM is activated a notice stating that a market correction event has occurred is published on the ACER website no later than 23:59 CET on the day of event.

Upon the activation, orders on TTF derivatives (front-month to front-year) €35 above the MCM reference price cannot be accepted. Should the MCM reference price be lower than 145 EUR/MWh, the MCM bidding limit is set at 180 EUR/MWh. 

The MCM bidding limit applies until:

• ACER publishes a deactivation notice 20 working days from the market correction event if the MCM reference price is below 145 EUR/MWh for three consecutive working days; or
• The European Commission suspends the MCM in case of significant deterioration of the gas supply situation in the EU.

Learn more about the MCM.

Today, ACER publishes its preliminary report on the effects of the Market Correction Mechanism (MCM) on energy markets and security of supply.

Background to the Market Correction Mechanism

The recently adopted MCM Regulation establishes a MCM to protect citizens and the economy against excessively high gas prices.

The MCM sets a bidding limit on certain financial derivatives traded at EU exchanges with the aim of limiting EU gas prices. This bidding limit is triggered when specific conditions are met.

The Regulation tasks ACER and the European Securities and Markets Authority (ESMA) with publishing a report (by 1 March 2023) to assess the market effects resulting from the introduction of the MCM, and a preliminary report by 23 January 2023.

ESMA also published their preliminary report today.

MCM has not had an impact on EU gas markets to date

So far, ACER has not identified significant impacts (positive or negative) that could be unequivocally and directly attributed to the adoption of the MCM Regulation itself. Its entry into force coincided with a time when prices were significantly lower compared, notably, to the second half of 2022. ACER cannot conclude that these market dynamics in the first weeks of 2023 are a direct or indirect effect of the approval of the MCM Regulation.

However, this does not preclude any impact on financial and energy markets in the future. Hence, both Agencies are proposing indicators to continue monitoring market developments and help detect potential future impacts of the MCM.

ACER welcomes feedback on the MCM indicators

In its preliminary report, ACER proposes to use eleven market indicators in its final effects report due on 1 March 2023. These indicators cover across three areas: prices, flows and trades.

ACER welcomes stakeholder feedback on these indicators, and in particular on the following questions:

• Are there any potential effects that could be triggered by the MCM, and early warning signs that should be monitored, that have not been identified in this ACER report?
• Are there any indicators that you consider relevant for assessing the effects of the MCM that have not been discussed in this ACER report?
• Are there any other points which you consider relevant to improve the ACER report on the effects assessment of the MCM that is due on 1 March?

Interested parties should send their feedback on the indicators by Monday, 6 February 2023, to MCM_effects@acer.europa.eu.

See the ACER preliminary report and the ESMA preliminary report.
