Cross-zonal capacity
European Union Electricity Market Glossary

 

 

 

'Cross-zonal capacity' means the capability of the intercon­nected system to accommodate energy transfer between bidding zones (Article 2(10) of the Regulation 543/2013 of 14 June 2013 on submission and publication of data in electricity markets).

 

Cross-zonal capacity can be expressed either as a coordinated net transmission capacity (CNTC) value or flow-based parameter.

 

Firmness of allocated cross-zonal capacity is crucial from the perspective of electricity trading.

 

Current EU legal framework regarding calculation of cross-zonal capacities is predicated on Article 16(3) of the Regulation (EC) No 714/2009 of the European Parliament and of the Council of 13 July 2009 on conditions for access to the network for cross-border exchanges, which reads:

 

“The maximum capacity of the interconnections and/or the transmission networks affecting cross-zonal flows shall be made available to market participants, complying with safety standards of secure network operation”.

 

Moreover, Point 1.7 of Annex I to the same Regulation stipulates that Transmission System Operators (TSOs) must not limit interconnection capacity in order to solve congestion inside their own control area.

 

Another important rule is expressed in Article 21(I)(b)(ii) of the Commission Regulation (EU) 2015/1222 of 24 July 2015 establishing a Guideline on Capacity Allocation and Congestion Management - CACM (Regulation on market coupling), which specifies that capacity calculation and allocation methodologies must be based on “rules for avoiding undue discrimination between internal and cross-zonal exchanges”.

 

Recommendation of the Agency No 02/2016 of 11 November 2016 on the common capacity calculation and redispatching and countertrading cost-sharing methodologies establishes two high-level capacity calculation principles:

 

1. limitations on internal network elements should not be considered in cross-zonal capacity calculation methods,

 

2. the capacity of the cross-zonal network elements considered in the common capacity calculation methodologies should not be reduced in order to accommodate Loop Flows (LFs).

 

TSOs and National Regulatory Authorities (NRAs) are expected by the ACER to follow these high-level principles when developing, approving, implementing and monitoring their capacity calculation methodologies.

 

However, the Recommendation allows for deviations from these principles if they are properly justified (from an operational security and socio-economical point of view at the EU level) and do not unduly discriminate against cross-zonal exchanges.

 

Building on the above approach ACER/CEER Annual Report on the Results of Monitoring the Internal Electricity and Gas Markets in 2016 (Electricity Wholesale Markets Volume, October 2017, p. 21, 22) introduced the concept of ‘benchmark’ capacity, which is defined as the capacity that could be made available to the market if the two high-level principles underlying the Recommendation No 02/2016 were strictly followed.

 

As deviations from the high-level principles are acceptable subject to adequate justifications, as outlined above, according to ACER and CEER the monitoring of capacity calculation should not only focus on the deviations from the benchmark capacities but also on the proportion of capacity of Critical Network Elements (CNEs) that is made available for cross-border exchanges and the proportion reserved for internal exchanges.

 

In 2017, two sets of data enabling the ACER to enhance its analysis on cross-zonal capacity calculation, were provided to the ACER for the first time:

 

1. TSOs provided information on the Common Grid Model (CGM) for continental Europe,

 

2. the Core (CWE) region TSOs provided via ENTSO-E detailed information on the most relevant data items used in the flow-based capacity calculation process in the Core (CWE) region (data included, inter alia, hourly information on the forecasted physical flows on internal and cross-zonal transmission lines in the Core (CWE) region resulting from internal exchanges, these forecasted physical flows are used to define the constraints determining the tradable cross-zonal capacity in a flow-based context).

 

To increase the cross-zonal capacity ACER recommended the full implementation of the principles on cross-zonal capacity calculation included in the aforementioned Recommendation No 02/2016, i.e.:

 

- the maximum feasible cross-zonal capacity should be made available to the market rather than the left overs,

 

- the costs of the remedial actions (e.g. redispatching) needed to guarantee maximum cross-zonal capacity should be fairly shared among TSOs.

 

Where the use of the available remedial actions is not sufficient to ensure an appropriate level of cross-zonal capacities, or it is found to be ‘too costly’, the ACER recommends that a reconfiguration of bidding zones be applied.

 

According to the ACER the EU Member States could consider setting a binding target for the availability of existing and future cross-border capacity, e.g. by defining a minimum share of physical cross-zonal capacity which should be made available for cross-zonal trade.

 

The underlying assumption of the above ACER’s analysis is that if the bidding zones are properly defined according to physical constraints the only factor limiting trade between two bidding zones is the capacity of the network elements on the bidding zone borders (i.e. the interconnection lines).

 

In order to assign a benchmark capacity value to a specific border, a distinction between HVDC (High-Voltage Direct Current) interconnectors and High-Voltage Alternating Current (HVAC) interconnectors needs to be made.

 

In the case of HVDC interconnectors, the benchmark capacity is assumed to be equal to the thermal capacity of the interconnector (since HVDC interconnectors are virtually unaffected by the factors that impact available cross-zonal capacity on HVAC interconnectors).

 

In the case of HVAC interconnectors, there are also other elements limiting the capacity that can be offered to the market.

 

HVDC interconnectors are not impacted by unscheduled flows (composed of Loop Flows, along with the unscheduled allocated flows (UAFs)).

 

HVDC interconnectors, moreover, are usually not considered in the N-1 assessment.

 

In the forward markets perspective, currently, there are multiple cross-zonal allocation rules in the EU to be aligned and implemented by the forward capacity single allocation platform (SAP) based on harmonised allocation rules.

 

The objective of optimising the allocation of long‐term cross‐zonal capacity is achieved with the Forward Capacity Harmonised Allocation Rules (HAR), hence, the harmonised rules will simplify the trading activities for long‐term products across European borders (Recital 8 of the Annex I to the ACER Decision 03/2017).

 

 

Cross-zonal capacity for balancing services

 

 

Cross-zonal capacity for balancing services is regulated in Articles 36 - 43 of the Commission Regulation (EU) 2017/2195 of 23 November 2017 establishing a guideline on electricity balancing - see box below.

 

According to Article 38(7) of the said Commission Regulation (EU) 2017/2195 of 23 November 2017 if physical transmission right holders use cross zonal capacity for the exchange of balancing capacity, the capacity shall be considered as nominated solely for the purpose of excluding it from the application of the use-it-or-sell-it (‘UIOSI’) principle.

 

Article 39 of the said Regulation envisions the following rules for the calculation of market value of cross-zonal capacity:

 

1. the market value of cross-zonal capacity for the exchange of energy and for the exchange of balancing capacity or sharing of reserves used in a co-optimised or market-based allocation process is based on the actual or forecasted market values of cross-zonal capacity;

 

2. the actual market value of cross-zonal capacity for the exchange of energy is calculated based on the bids of market participants in the day-ahead markets, and take into account, where relevant and possible, expected bids of market participants in the intraday markets;


3. the actual market value of cross-zonal capacity for the exchange of balancing capacity used in a co-optimised or a market-based allocation process is calculated based on balancing capacity bids submitted to the capacity procurement optimisation function;


4. the actual market value of cross-zonal capacity for the sharing of reserves used in a co-optimised or a market-based allocation process is calculated based on the avoided costs of procuring balancing capacity;


5. the forecasted market value of cross-zonal capacity is based on one of the following alternative principles:
(a) the use of transparent market indicators that disclose the market value of cross-zonal capacity; or
(b) the use of a forecasting methodology enabling the accurate and reliable assessment of the market value of cross-zonal capacity;

 

6. the forecasted market value of cross-zonal capacity for the exchange of energy between bidding zones is calculated based on the expected differences in market prices of the day-ahead and, where relevant and possible, intraday markets between bidding zones (additional relevant factors influencing demand and generation patterns in the different bidding zones are also taken into account).

 

Market-based allocation process of cross-zonal capacity

 

According to Article 41(2) of the said Commission Regulation (EU) 2017/2195 of 23 November 2017 cross-zonal capacity allocated on a market-based process shall be limited to 10 % of the available capacity for the exchange of energy of the previous relevant calendar year between the respective bidding zones or, in case of new interconnectors, 10 % of the total installed technical capacity of those new interconnectors.

 

This volume limitation may not apply where the contracting is done not more than two days in advance of the provision of the balancing capacity or for bidding zone borders connected through DC interconnectors until the co-optimised allocation process is harmonised at Union level.

 

Article 41(5) of the said Commission Regulation (EU) 2017/2195 of 23 November 2017 stipulates that cross-zonal capacity allocated for the exchange of balancing capacity or sharing of reserves via the market-based allocation process shall be used only for the exchange of balancing capacity or sharing of reserves and associated exchange of balancing energy.

 

Allocation of cross-zonal capacity based on an economic efficiency analysis

 

Article 42(2) of the said Commission Regulation (EU) 2017/2195 of 23 November 2017 stipulates that the allocation of cross-zonal capacity based on an economic efficiency analysis shall be limited to 5 % of the available capacity for the exchange of energy of the previous relevant calendar year between the respective bidding zones or, in case of new interconnectors, 10 % of the total installed technical capacity of those new interconnectors.

 

This volume limitation may not apply for bidding zone borders connected through DC interconnectors until the co-optimised or market-based allocation processes are harmonised at Union level.

8. All TSOs exchanging balancing capacity or sharing of reserves shall regularly assess whether the cross-zonal capacity allocated for the exchange of balancing capacity or sharing of reserves is still needed for that purpose. Where the allocation process based on economic efficiency analysis is applied, this assessment shall be done at least every year. When cross-zonal capacity allocated for the exchange of balancing capacity or sharing of reserves is no longer needed, it shall be released as soon as possible and returned in the subsequent capacity allocation timeframes. Such cross-zonal capacity shall no longer be included as already allocated cross-zonal capacity in the calculations of cross-zonal capacity.


9. When cross-zonal capacity allocated for the exchange of balancing capacity or sharing of reserves has not been used for the associated exchange of balancing energy, it shall be released for the exchange of balancing energy with shorter activation times or for operating the imbalance netting process.

 

Article 39

Calculation of market value of cross-zonal capacity

The forecasted market value of cross-zonal capacity for the exchange of energy between bidding zones shall be calculated based on the expected differences in market prices of the day-ahead and, where relevant and possible, intraday markets between bidding zones. When calculating the forecasted market value, additional relevant factors influencing demand and generation patterns in the different bidding zones shall be taken duly into account.


6. The efficiency of the forecasting methodology pursuant to paragraph 5(b), including a comparison of the forecasted and actual market values of the cross-zonal capacity, may be reviewed by the relevant regulatory authorities. Where the contracting is done not more than two days in advance of the provision of the balancing capacity, the relevant regulatory authorities may, following this review, set a limit other than that specified in Article 41(2).


Article 40

Co-optimised allocation process

 

1. By two years after entry into force of this Regulation, all TSOs shall develop a proposal for a methodology for a co-optimised allocation process of cross-zonal capacity for the exchange of balancing capacity or sharing of reserves.

Article 42

Allocation process based on economic efficiency analysis

 

1. By two years after entry into force of this Regulation, all TSOs of a capacity calculation region may develop a proposal for a methodology for the allocation of cross-zonal capacity based on an economic efficiency analysis. Such methodology shall apply for the exchange of balancing capacity or sharing of reserves with a contracting period of more than one day and where the contracting is done more than one week in advance of the provision of the balancing capacity. The methodology shall include:
(a) the rules and principles for allocating cross-zonal capacity based on an economic efficiency analysis;
(b) a detailed description of how to determine the forecasted market value of cross-zonal capacity for the exchange of balancing capacity or sharing of reserves, and an assessment of the market value of cross-zonal capacity for the exchange of energy;

(d) the maximum volume of allocated cross-zonal capacity for the exchange of balancing capacity or sharing of reserves pursuant to paragraph 2.


2. The allocation of cross-zonal capacity based on an economic efficiency analysis shall be limited to 5 % of the available capacity for the exchange of energy of the previous relevant calendar year between the respective bidding zones or, in case of new interconnectors, 10 % of the total installed technical capacity of those new interconnectors. This volume limitation may not apply for bidding zone borders connected through DC interconnectors until the co-optimised or market-based allocation processes are harmonised at Union level pursuant to Article 38(3).


3. The methodology for the allocation of cross-zonal capacity based on an economic efficiency analysis shall be based on a comparison of the forecasted market value of cross-zonal capacity for the exchange of balancing capacity or sharing of reserves, and the forecasted market value of cross-zonal capacity for the exchange of energy.


4. The pricing method, the firmness regime and the sharing of congestion income for the cross-zonal capacity that has been allocated for the exchange of balancing capacity or sharing of reserves based on an economic efficiency analysis shall ensure equal treatment with the cross-zonal capacity allocated for the exchange of energy.


5. TSOs referred to in paragraph 1 shall develop a proposal for a list of each individual allocation of cross-zonal capacity based on an economic efficiency analysis. Such list shall include:
(a) the specification of the bidding zone border;
(b) the volume of allocated cross-zonal capacity;
(c) the period during which the cross-zonal capacity would be allocated for the exchange of balancing capacity or sharing of reserves;
(d) the economic analysis justifying the efficiency of such allocation.


6. TSOs referred to in paragraph 1 shall reassess the value of the allocated cross-zonal capacity in the process of the procurement of balancing capacity and release the allocated cross-zonal capacity which is no longer beneficial for the exchange of balancing capacity or sharing of reserves.


Article 43

Use of cross-zonal capacity by balancing service providers

 

1. Balancing service providers which have a contract for balancing capacity with a TSO on the basis of a TSO-BSP model pursuant to Article 35 shall have the right to use cross-zonal capacity for the exchange of balancing capacity if they are holders of physical transmission rights.


2. Balancing service providers which use cross-zonal capacity for the exchange of balancing capacity on the basis of a TSO-BSP model pursuant to Article 35 shall nominate their physical transmission rights for the exchange of balancing capacity to the concerned TSOs. Such physical transmission rights shall provide the right to their holders to nominate the exchange of balancing energy to the concerned TSOs and shall therefore be excluded from the application of the UIOSI principle.


3. Cross-zonal capacity allocated for the exchange of balancing capacity in accordance with paragraph 2 shall be included as already allocated cross-zonal capacity in the calculations of cross-zonal capacity.

 

 

 

Winter Energy Package approach to the cross-zonal capacity calculation

 

 

Winter Energy Package (Annex to the Proposal for a Regulation of the European Parliament and of the Council on the internal market for electricity (recast), 30.11.2016, COM(2016) 861 final 2016/0379 (COD)) provides for the coordinated calculation of cross zonal capacities.

 

 

Proposal for a Regulation of the European Parliament and of the Council on the internal market for electricity (recast), 30.11.2016, COM(2016) 861 final 2016/0379 (COD)

 

Article 15


Allocation of cross-zonal capacity across timeframes

 

1. Transmission system operators shall recalculate available cross-zonal capacity at least after day-ahead and after intraday cross-zonal gate closure times. Transmission system operators shall allocate the available cross-zonal capacity plus any remaining cross-zonal capacity not previously allocated and any cross-zonal capacity released by physical transmission right holders from previous allocations in the next cross-zonal capacity allocation process.


2. When cross-zonal capacity is available after the intraday cross-zonal gate closure time, transmission system operators shall use the cross-zonal capacity for the exchange of balancing energy or for operating the imbalance netting process.


3. Transmission system operators shall use the methodologies developed in network codes and guidelines on balancing, where applicable, to allocate cross-zonal capacity for the exchange of balancing capacity or sharing of reserves pursuant to Article 5(4) and (7).


4. Transmission system operators shall not increase the reliability margin calculated pursuant to Regulation (EU) 2015/1222 due to the exchange of balancing capacity or sharing of reserves.

 

This task is entrusted to Regional Operational Centres (ROCs).

 

According to the aforementioned rules coordinated capacity calculation should be performed:


- for each market timeframe,


- as frequently as needed during the intraday timeframe,


- based on a common system model and on the coordinated capacity calculation methodology developed by the transmission system operators of the relevant system operation region.

 

Coordinated capacity calculation must, moreover, ensure efficient congestion management in accordance with the principles of congestion management defined in the said draft Regulation.
