Nemo Link, safeguarding the future while preserving the past

< Back to index

We hear more and more about the vital role of interconnectors in connecting to a Net Zero future but we’re not often told how the past can be rediscovered and preserved in the build of an interconnector… It’s the story of the Nemo Link Interconnector and the discovery of a mysterious 18th century cannon.

Discovery of the cannon

Pegwell Bay, the location of the Nemo Link connection point in England, is already famous in history as the landing site of Julius Caesar’s invading Roman army in 54BC.  Before construction, Nemo Link commissioned Wessex Archaeology to undertake a programme of specialist archaeological consultancy for the UK element of the marine cable route. The survey data relating to the cable route were assessed for archaeology, which identified ‘anomalies’ that could be damaged by, or cause damage, during the laying of the interconnector cables.

In 2016, a magnetic anomaly was identified during one of these surveys, off the Kent coast (South East England) that indicated buried metal material that could be of archaeological interest. The site was visually inspected the following year by marine archaeological experts using a Remotely Operated Vehicle (ROV) that identified it as a heavily concreted cannon. The object was recovered from the seabed and taken to Wessex Archaeology’s Coastal and Marine department in Salisbury, Wiltshire for further analysis.

Interesting features and findings to the gun’s history

When the cannon was lifted, it was covered in a thick ‘concretion’ of natural marine material which had built up on its surface over the centuries spent on the seabed.

The cannon’s lead apron, which covered the touch hole where the gun was lit, was still attached with retaining strings, suggesting that the gun was still in use when it was lost.

The cannon’s tampion – a wooden stopper used to close the muzzle of the gun barrel – was found sealing its bore, suggesting it could have been loaded at the time of its loss.

The shape and proportions of the cannon suggest it was cast to the ‘Borgard pattern’, meaning it is likely to have been cast between 1715 and 1727. Three pounder guns such as this one were often used as a defensive measure by merchant ships.

Relocation of the cannon

The Wessex Archaeology team have also helped Nemo Link design a bespoke display case for this interesting discovery to contribute to the cannon’s long-term preservation. The cannon is now installed in its custom case, made by conservation experts Armour Systems and showcased in our office at 35 Homer Road, Solihull, UK.

We are excited to showcase this piece of history while continuing to play our part in accelerating to a clean energy future.  Perhaps in 300 years a part of Nemo Link, our interconnector will also be proudly on display explaining how it enabled the sharing of renewable energy across Europe?

Nemo Link celebrates another outstanding performance in the extraordinary year of 2020

< Back to index

It’s fair to say 2020 was an extraordinary year for the world and for Nemo Link, the first ever UK- Belgium interconnector in its second year of operation, it has also marked another outstanding year of performance despite its challenges.

Highest availability of its kind

The Nemo Link Interconnector celebrates the end of 2020 with 99.17% availability, continuing to be one of the highest performing assets of its kind in the world. In 365 days of continuous operation, Nemo Link only had 6 hours of unplanned outages and 67 hours of planned maintenance work, even with all planning and execution right in the middle of a pandemic. In 2020, Nemo Link had 2 periods of operating with no interruption at all (198 days in Q1 & Q2 and 99 days in Q4). On safety, Nemo Link had no accidents on site over the year and more importantly, the interconnector managed to operate safely and efficiently with all essential COVID safety measures in place.

Commercial achievement

On the commercial front, it has been a busy year for the team preparing for Brexit to ensure a smooth transition following GB’s departure from the EU’s Internal Energy Market.  This includes operational system and procedure readiness to extensive engagement with customers, regulators and stakeholders. On 31st December 2020, Nemo Link successfully ran its 1st explicit day ahead auction, ensuring power continued to flow between GB and Belgium without any interruption in the new trading arrangement. With 62% of its capacity already having been locked in at solid prices for 2021, Nemo Link was heading into 2021 with a good start.

2020 was also the first full year that Nemo Link has run its Intraday product with hourly nomination gates.  Nemo Link’s intraday product allows our customers to quickly react to volatility after day-ahead market closure and 19th April 2020 was a particularly good example of its impact. On the day, solar production in Belgium fell significantly below the day-ahead forecast, resulting in a short Belgian system and imbalance prices of up to 359€/MWh. Nemo Link’s intraday customers reacted by reducing exports to GB, thereby helping to restore the demand-supply balance.

After the first full year of successful operations, Nemo Link also reviewed its observed losses and announced the new Loss Factor which was lowered from 2.6% to 2.372%, effective from September 2020. This has been highly received by our customers as it brings more efficiency for every Megawatt that they intend to flow on the Interconnector.

In summary, it’s been an exceptional year providing the market with world class asset availability, a wide product mix, a reliable trading and nomination system, and a strong customer focus which has rewarded Nemo Link with another outstanding 86% customer rating for Ease-of-doing-business.  We aim to continually improve and have a strong foundation from which to build.

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

< Back to index

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

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 5th May, meaning Nomination Gate 1 will close at 22:50 CEST on 4th 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.
