Nemo Link updates its dynamic overload facility hours

< Back to index 16th April 2024

From tomorrow, 17 April 2024, Nemo Link will move its dynamic overload facility which is current running each day between 17:00 – 22:00 CE(S)T to new timings between 10:00 – 15:00 CE(S)T.

This means the Maximum Physical Transfer Capacity (MPTC) of the interconnector at mid-channel reference point will be 1032MW for a period of 5 hours each day between 10:00-15:00 CE(S)T and please note this is only available in the direction BE to GB.

Subject to the day ahead capacity calculation process, market participants will see Nemo Link’s unrestricted Day Ahead Net Transfer Capacity (NTC) of 1032MW (BE to GB direction) between 10:00-15:00 CE(S)T in the day ahead auction on 16 April 2024 for delivery on 17 April 2024.

Any unallocated capacity will flow through to intraday auctions, subject to a further intraday capacity calculation process.

Effective from delivery 17/04/2024 until further notice

Background information:

The design of the interconnector means that Nemo Link has the ability to operate the interconnector for short periods (e.g. 5 hours) in excess of its nominal continuous rating by taking advantage of the thermal characteristics of the plant and the in-built redundancy of the cooling systems. Increasing the flow of the interconnector by 20MW is therefore possible for a few hours. This has been introduced on Nemo Link since 18^th December 2019.

If you have any questions or need any further information, please don’t hesitate to contact the Customer Team.

Nemo Link Shadow Day Ahead Auction in the event of Decoupling

< Back to index 7th June 2019

Market Decoupling event on 7^th June 2019

As you will have been aware, on Friday 7^th June, EPEX SPOT encountered technical issues in the Day-Ahead auction which impacted the Belgium and GB markets. Further information on the event can be found here.

As a fall-back solution for Market Coupling, Nemo Link through the Joint Allocation Office ran its shadow day-ahead explicit auctions which took place at 12:35 CEST 7^th June. However, as only default bids are accepted for shadow auctions on JAO’s eCAT system and there were no default bids for the GB-BE border before the event, the auctions cleared at 0MW.

Nemo Link (with the support of JAO and Elia’s operations teams) carried out additional processes at very short notice to provide customers with additional trading opportunities and ran an extra day ahead explicit auction at 18:30 CEST 7^th June. All available transfer capacity in the direction BE to GB was allocated in which 4 market participants managed to obtain the physical transmission rights and nominated all the acquired capacity through the Regional Nomination Platform RNP successfully.

Nemo Link’s Shadow Day Ahead Explicit Auctions

Even though cases like this are extremely rare, as proven on 7^th June, it can happen. In order for market participants to be ready for the possibility of a similar event in future and if you would like to utilise Nemo Link’s Shadow Auction, the following are required:

Registered as a physical customer with Nemo Link to have the ability to nominate
Have indicated with JAO to participate in Shadow Auctions for the GB-BE border (have sent Amendment No. 6 to the JAO’s Participant Agreement or send the Modification Request to include GB-BE border).
-> All the relevant documents and forms requested for registration are available on the JAO website under the “Support” tab / “Resource center” in the “Registration” Section (scroll down in the panel on the left)
Have entered default bids in JAO’s e-CAT for Shadow Auctions on GB-BE border

If you have any questions about this process or wish to talk to someone about the systems involved, please contact the Customer Team.
