Instant data on electricity flows across the new 1.4 GW Viking interconnector is now available from Elexon. The Viking Link is the world’s longest land and subsea electricity cable, connecting the East of England with Denmark.

Making the flow data for the Viking Link available is important so that Elexon can continue to provide more transparency to anyone that monitors the electricity market.

The Credit Assessment Load Factor (CALF) values for the spring 2024 BSC Season, which runs from 1 March 2024 to 31 May 2024, are available from the Credit/Credit Alerting section under the Financial and Credit menu on the ELEXON Portal.

If you are the Lead Party of a non-Credit Qualifying BMU, you can appeal an assigned CALF value if you believe it does not accurately represent your expected activity.

A significant amount of work is being done by Elexon and the Market-wide Half Hourly Settlement Programme (MHHSP) to make changes to BSC documents (or to develop new documents) in preparation for MHHS.

The Market Wide Half-Hourly Settlement (MHHS) Programme has implemented a Programme Change Freeze. This means that any BSC Changes that require changes to the MHHS design or MHHS code drafting (via a MHHS Change Request) are likely to have their implementation postponed. 

Code Bodies presented the MHHS Qualification Plan to Suppliers and Supplier Agent representatives in an extraordinary Qualification Working Group (QWG) meeting on Monday 27 November.

The Qualification Plan provided the current position for Supplier and Supplier Agent Qualification alongside the Qualification Approach & Plan (QAP) and the Qualification Assessment Document (QAD) timelines.

This page lists changes to the status of Balancing and Settlement (BSC) Parties and Qualified Persons in November. It includes information on any new qualifications and registrations, new market participants, withdrawals and defaults.

We have launched the new BSC Service Status Dashboard today (20 November) so that Parties can see an up to the minute view of whether there are any issues with the BSC services that we provide.

The Unmetered Supplies (UMS) Material Error Monitoring (MEM) threshold will reduce from 10,000MWh to 7,000MWh, effective from the Quarter 1 2024 reporting window.

We have released three new dates for our Introduction to the Energy Market seminars in 2024. Find out more below and sign up to attend.

The Winter BSC Season begins on Friday 1 December 2023. The deadline for submitting your GC and DC values for the Summer BSC Season is Thursday 16 November 2023.

Even if the values are identical to the last BSC Season you need to submit values for the new Season.

The MHHS Programme is introducing changes for legacy Suppliers and agents to support the Migration of Metering System Identifiers (MSIDs) from legacy arrangements to MHHS. Reverse migration can take place during the migration period (from March 2025 onwards) where a customer has switched to a Supplier that is not yet MHHS Qualified.

This month (October 2023) Elexon has begun to administer a new support scheme to benefit electricity prepayment meter (PPM) customers this winter by discounting their daily standing charges. Xoserve (a gas industry code manager) will be administering the equivalent scheme for gas PPMs.

Following the issues mentioned in Elexon Circular EL03922 we have recently deployed a fix that addresses the issue with processing of large volume of Maximum Export Limit (MEL) data on our Balancing Mechanism Reporting Service (BMRS).
