Nemo Link consults on changes to non-IEM Explicit Day Ahead Auctions

< Back to index 16th October 2020

Nemo Link already has in place a set of Non-IEM Access Rules that have been approved and will be operational from 1st January 2021 when GB leaves the IEM. This consultation proposes some minor adjustments to those trading rules, and if supported by market participants, could be implemented in Q1 2021 subject to regulatory approval.

Background
The initial Nemo Link Non-IEM access rules were developed to enable continued trading in the event GB left the Internal Energy Market. At the time, it was necessary to focus mainly on established operational processes to ensure a robust and smooth handover. However, over the Brexit transition period, we have had the opportunity to assess and discuss in greater depth whether the current Non-IEM access rules can be better optimised to deliver the most efficient trading environment.

Relevant Documents
Please find below the relevant documents which outlines the proposed changes:

Consultation Invitation Letter (please read first)
Non-IEM Access Rules (track change version)

Consultation topics
The main topics of the consultation are summarised below:

Day Ahead Firmness Deadline changed from 11:00 to 09:00 (Appendix 1 Article 58)
LT Nomination window timing changed from 09:00 to 08:45 (Appendix 2 Article 6)
Adjustment to the timings of the explicit day ahead capacity auction that will replace the implicit day ahead auction. Nemo Link proposes moving the opening time from 09:40 to 09:00 CE(S)T (Appendix 3 Article 26)
Day Ahead Nomination window shortening from 12:05-14:00 to 12:05 to 13:30 (Appendix 5 Annex to the Explicit Day Ahead and Intraday Nomination Rules Paragraph 1)

In addition, Nemo Link would like to invite feedback from market participants on the following topics:

Do you agree a Day Ahead energy auction in GB earlier than SDAC could lead to more efficient interconnector trading?
How important is a single GB power reference price?

Timeline
We welcome all market participant and stakeholder comments or questions on the proposals by email to customer.service@nemolink.co.uk by 18:00 CET 13th November 2020.

If you have any questions, please contact the Customer Team.

Nemo Link announces its new Loss Factor effective from 1 September 2020

< Back to index 2nd July 2020

After the first full year of successful operations, Nemo Link has reviewed its observed losses and is now pleased to announce the new Loss Factor on the Nemo Link Interconnector.

Effective from Delivery Day 1 September 2020 at 00:00 CEST, Nemo Link Interconnector’s Mid-Point Loss Factor will be lowered from 2.600% to 2.372%. The Mid-Point Loss Factor is the loss factor that is used in Nemo Link’s Access Rules (see Annex Business Rules for Nemo Link paragraph 3) and Nemo Link’s Border Specific Annex.

Nemo Link’s Mid-Point Loss Factor

2.600%

Effective until 23:59 CEST 31/08/2020

2.372%

Effective from 00:00 CEST 01/09/2020

Nominations at Nemo Link’s importing and exporting end for a specific mid-interconnector nomination are calculated using the Mid-Point Loss Factor (LF) as follows:

Importing end nomination = mid-interconnector nomination * (1-LF/2)
Exporting end nomination = mid-interconnector nomination * (1+LF/2)

UIoSI compensations for non-nominated Long Term Transmission Rights equal the loss adjusted day ahead market spread (LADAMS) as follows:

If GBDAMP > BEDAMP, LADAMS = (1-LF/2)*GBDAMP – (1+LF/2)*BEDAMP
If BEDAMP > GBDAMP, LADAMS = (1-LF/2)*BEDAMP – (1+LF/2)*GBDAMP
(GBDAMP: GB Day ahead market price BEDAMP: BE Day ahead market price)

Full details on UIoSI compensations can be found on the Nemo Link’s Border Specific Annex (see chapter 3).

The mid-interconnector reference capacity will decrease from 1013 MW to 1012 MW in regular operation and from 1033 MW to 1032 MW in overload operation. Nemo Link’s Capability remains 1000 MW at the importing end.

Further information can be found on the Nemo Link Loss Factor document published on the Publications area.

Nemo Link announces its new Intraday Nomination timings

< Back to index 1st May 2020

At Nemo Link, we highly value feedback from customers and always seek for improvements on our products and services.

Following recent conversations with our customers, we are now increasing intraday nomination gate opening times from 45 minutes to 50 minutes. This would mean that capacity holders intending to nominate intraday transmission rights could do so up to 70 minutes ahead of delivery instead of the current 75 minute lead time. Therefore, Nemo Link customers will now be able to further optimise their positions to respond to rapidly changing market conditions.

Nemo Link intends to implement the change from the first nomination gate for delivery day 5^th May, meaning Nomination Gate 1 will close at 22:50 CEST on 4^th May 2020. An updated summary of the Nemo Link intraday auction and nomination times can be found here.

So within 6 months of successful intraday operations, Nemo Link is proud to make changes quickly to adapt to customer feedback and needs.

We would like to thank our customers for their valued feedback and we welcome suggestions from all market participants to continue to improve Nemo Link’s products and services.

Nemo Link celebrates strong performance in its first full year of operation

< Back to index 4th February 2020

Nemo Link, the first ever power cable between the UK and Belgium, has today reported outstanding performance figures as it celebrates its first full year of operation.

The subsea cable has been available to import or export power more than 96% of the time in the last 12 months, making it one of the highest performing assets of its kind in the world.

Stretching 140 km from Bruges on the Belgian side to Richborough in Kent, Nemo Link is a joint venture between the Belgian transmission system operators Elia and National Grid in the UK. It began operating on January 31, 2019, offering a range of products that enable energy traders to move electricity back and forth between the two countries. This provides additional options and flexibility for the Belgian and UK electricity markets.

The Nemo Link cable has a capacity of 1,000 megawatts. It was also the first subsea HVDC project in the world to use cross linked polyethylene (XLPE) cable technology. Flows have been primarily in the direction of the UK. 5889.4 GWh were exchanged in the direction of the UK against 175.9GWh in the direction of Belgium.

Intraday nomination gates

On November 14th 2019, Nemo Link launched an Intraday Capacity product being the first channel interconnector to offer hourly nomination gates. The capability to balance the grid closer to real time operations is beneficial for market participants as it allows them to take unexpected changes in consumption and production into account.
This new product has immediately proven successful in December when the Tihange’s (BE) nuclear reactor (1 GW) stopped functioning (37 hours) and Belgian energy production was low. This created an imbalance peak. With Nemo Link the interconnector was therefore able to offer quick solutions to rebalance the positions thanks to its technical flexibility and its offer of products that allow reacting in real time.

“We’ve seen in the last year how Nemo Link has used innovative new technology to bring significant benefits to Belgian and British energy consumers. By enabling the market to react immediately to rapid changes in supply and demand, Nemo helps to better balance an energy system that is more reliant on intermittent wind and solar energy. In the coming years, interconnectors like Nemo will play an increasingly important role as we look to share renewable energy resources across borders to help the UK and Europe get to net zero carbon emissions by 2050.”
Jon Butterworth, President of National Grid Ventures

“We are delighted to mark our one-year anniversary by announcing that the Interconnector Nemo Link has performed exceptionally well. The advanced technology used for this cable is unprecedented in the world, we have designed and provided a resilient and efficient interconnection which guarantees available power when needed.”
Markus Berger, Director of Infrastructure at Elia
