Brexit Update – No trading changes in the Transition Period

< Back to index 30th January 2020

Following votes both in the House of Commons and in the European Parliament ratifying the Withdrawal Agreement, the United Kingdom will leave the EU tomorrow and enter the “Transition Period”.

This means that we can confirm there will be no changes whatsoever to any trading arrangements on Nemo Link at this time and the country remains within the Internal Energy Market. The next key date, depending on the outcome of the UK-EU negotiations will be 31^st December 2020 and we will keep you notified of any developments.

It is our expectation however that the UK will not be permitted to remain within the Internal Energy Market beyond 31/12/20. Therefore Nemo Link urge all customers that have not already done so to register as physical participants to benefit from Day Ahead explicit auctions which will replace implicit auctions in the scenario that GB leaves the IEM.

Please contact the Customer Team if you would like to discuss further.

Nemo Link Announces Transient Overflow Facility

< Back to index 10th December 2019

Nemo Link today announces that from 18^th December 2019, the Maximum Physical Transfer Capacity (MPTC) of the interconnector will increase by 20MW for a period of 5 hours each day between 17:00-22:00 CET and will only be available in the direction Belgium to GB.

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.

Subject to the day ahead capacity calculation process, market participants will see an increase in Nemo Link’s unrestricted Day Ahead NTC to 1046MW (BE to GB direction) between 17:00-22:00 CET in the day ahead auction on 17th December for delivery on 18^th December as follows:

	Maximum Day-Ahead NTC at Importing End 17:00 – 22:00 CET	Maximum Day-Ahead NTC at Exporting End 17:00 – 22:00 CET
BE to GB	1020 MW	1046 MW
GB to BE	1000 MW	1026 MW

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

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

Intraday trading goes live between Great-Britain and Belgium

< Back to index 15th November 2019

New within day Nemo Link products make it easier for market participants to manage intermittent renewables.

Since operational go-live in February 2019 it has been possible to trade electricity via the Nemo Link interconnector between Great Britain and Belgium on a Long Term and Day-ahead basis. From 14 November 2019 it is now also possible to trade electricity between both countries within day.

Intraday market trading is a very important option for electricity market participants. With rapidly growing intermittent renewable production, it is becoming an increasing challenge for market participants to remain in balance after the closing of the day-ahead market.

The capability to be balanced closer to real time operations is beneficial for market participants as it allows them to take unexpected changes in consumption and production into account.

The new explicit intraday capacity product on Nemo Link, with its hourly nomination gates, brings additional options and provides a level of flexibility welcomed by market players who trade both renewable and conventional energy.

Market participants can now participate in the four daily intraday capacity auctions that are organized by the Joint Allocation Office (JAO) and acquire capacity rights on the Nemo Link interconnector for periods up to 6 hours.

More information on Nemo Link’s trading framework and its new Intraday product can be found here.

The Nemo Link interconnector is a joint venture between National Grid Interconnector Holdings Limited, a subsidiary company of the UK’s National Grid Plc, and the Belgian Elia Group.

Nemo Link’s first intraday auctions start tomorrow

< Back to index 13th November 2019

The first intraday auction will be held tomorrow on the JAO’s eCAT platform between 09:30 and 09:55 CET. Below is a snap shot of all intraday auctions taking place tomorrow:

Regulators approve Nemo Link IEM and Non-IEM Access Rules

< Back to index 28th October 2019

Ofgem and CREG last week approved Nemo Link’s Access Rules meaning that customers can now trade with us over all timescales (Long Term, Day Ahead and Intraday), regardless of whether GB remains inside the Internal Energy Market. This is a significant achievement and comes as a result of big effort from the regulators to get the rules approved under time pressure. Nemo Link would like to thank customers and regulators for their input during consultation and approval processes.

Intraday Launch Event in Brussels, 23rd October 2019

< Back to index 25th October 2019

Customers and stakeholders gained important insights into Nemo Link’s latest capacity product expected to Go-Live on 14 November 2019 at our Intraday Launch workshop in Brussels this week. Nemo Link hosted the event which included the Nemo Link Commercial Team, JAO, Elia, National Grid ESO and Unicorn to share all aspects of Intraday Trading from auctions and nominations, to systems and processes.

Attendees also visited Coreso’s control room, learning more about cross border electricity flows and regional security coordination in NW Europe, and in particular how these processes can impact interconnector capacities.

We would like to thank everyone who attended the workshop and joined us at the Coreso’s visit.

No-Deal Brexit Single Day-Ahead Coupling Press Release

< Back to index

Single Day-Ahead Coupling (SDAC) is prepared for potential consequences of Brexit on implicit day-ahead market coupling

Nominated Electricity Market Operators (NEMOs) and Transmission System Operators (TSOs) are prepared for a potential scenario where the United Kingdom leaves the EU without a deal on 31 October 2019.

Should this scenario happen, the consequence would be the removal of Great Britain (GB) from implicit day-ahead market coupling. In that case the last implicit allocation on BritNed, IFA and Nemo Link would take place on 31 October (D-1), for delivery date 1 November (D). The first explicit allocation for day-ahead capacity on the BritNed, IFA and NemoLink interconnectors would take place on 1 November (D-1), for delivery date 2 November (D).

Given the uncertainty around Brexit, NEMOs and TSOs have agreed to a solution for the scenario where the United Kingdom leaves the EU without a deal. The solution foresees the removal of the GB bidding zone and lines connected to it from SDAC.

The Single Electricity Market (SEM), which encompasses the island of Ireland, would remain within the implicit day-ahead market coupling with the SEM bidding zone operated in an isolated mode. This solution has been successfully tested during September.

SDAC allocates scarce cross-border transmission capacity in the most efficient way by coupling wholesale electricity markets from different regions through a common algorithm, simultaneously taking into account cross-border transmission constraints, thereby maximising social welfare.

The aim of SDAC is to create a single pan European cross zonal day-ahead electricity market. An integrated day-ahead market increases the overall efficiency of trading by promoting effective competition, increasing liquidity and enabling a more efficient utilisation of generation resources across Europe.

< Back to index 23rd October 2019

Nemo Link and Elia are pleased to announce the expected GO-LIVE of its new intraday capacity product on 14^th November 2019. Nemo Link will be the first Channel interconnector to offer hourly nomination gates which will enable market participants to optimise physical positions close to real time.

Following a six-month project working closely with market participants, National Grid ESO, JAO and regulators, the new intraday capacity product will bring additional options and flexibility to Belgian and GB electricity markets. Market participants will be able to buy intraday capacity through explicit auctions on the JAO eCAT platform four times a day and nominate those capacity rights on the Regional Nomination Platform (RNP).

The first Intraday explicit auction for the GB-Belgium border is scheduled to open at 9:30 CET and close at 9:55 CET 14.11.2019 for the delivery period 12:00 to 18:00 CET.
