BSC Sandbox application process
Who is this guidance note for?
You’ll find this note helpful if you’re applying, or considering applying, for a derogation from the Balancing and Settlement Code (BSC) through the BSC Sandbox. You may be an innovator or a partner in an innovative trial. You may or may not be a BSC Party (signatory).
The BSC Sandbox supports Ofgem’s Energy Regulation Sandbox (ERS). All applications must be sent to Ofgem. This guidance should be read alongside Ofgem’s own ERS guidance. You can find links to Ofgem’s website at the end of this note.
Do you want to carry out a pre-competitive and time-limited trial, in a live market environment, of an innovative product, service, methodology or business model? If this trial isn’t compatible with normal energy licence or industry code rules, you can apply through Ofgem’s ERS for one or more derogations from these rules.
If your application to Ofgem’s ERS requires a derogation from an industry code that has its own sandbox derogation process (currently the BSC, DCUSA and REC) then Ofgem will let the relevant code administrator(s) know. The code administrator will co-ordinate their own supporting process.
For example, you may want to trial an activity or arrangement that would not normally be permitted by the BSC rules. Through the BSC Sandbox, Elexon assesses the risks and impacts of a derogation on behalf of the BSC Panel (the BSC’s governing committee). The Panel makes a recommendation to Ofgem and Ofgem makes the final decision.
What’s a BSC derogation and how long can I hold one?
A derogation gives you temporary permission, for a limited period of time, not to comply with one or more BSC rules. A derogation can be from rules in the BSC and/or its Code Subsidiary Documents, e.g. BSC Procedures (BSCPs).
The maximum time for which you can hold a BSC Sandbox derogation is 3 years in total. This includes:
2 years maximum for the Trial Period. You should apply for the shortest possible amount of time that you need to test your innovation.
An extra Transition Period, by the end of which you must have either transitioned back to full BSC compliance or progressed a permanent change to the BSC rules. You should plan to do this in the shortest time possible.
The Derogation Period you’re granted may therefore be less than the maximum shown in the diagram below.
It’s your commercial decision what start date you request for the derogation. But because of the above limits on timescales, we recommend that you choose a start date that gives you contingency for any potential delays in preparing for your trial. This increases your ability to be ready to go and make full use of the available Trial Period.
Who can use the BSC Sandbox?
The BSC Sandbox is open to both BSC Parties and non-Parties.
Derogations from BSC rules can only apply to the BSC Parties who would normally be bound by those rules. This means that, if your BSC Sandbox application is successful, you’ll need to accede to the BSC (become a BSC Party) in order for the derogation to be effective. You’ll need to factor this into your planning. Once you’ve acceded to the BSC, you’ll be bound by all BSC rules except those from which you’ve been granted a derogation.
Alternatively, if it better suits your trial, you can partner with an existing BSC Party in your application and ask to apply the derogation to them.
Applications must be made through Ofgem’s ERS by completing and submitting Ofgem’s application form. If your application needs a BSC derogation, Ofgem will notify Elexon. We’ll contact you to discuss next steps.
We’re always happy to help with potential applications before they’re submitted. But we can only offer advice and support on the BSC interactions and process. We can’t comment on your trial’s commercial viability or whether you’ll get Ofgem’s approval.
What happens after I apply?
Once Ofgem’s accepted your application into its ERS process, and it’s notified us of a BSC Sandbox impact, we will:
Contact you to discuss next steps. We may ask you for further information to help our assessment.
Identify whether we need to co-ordinate with other industry code sandbox processes.
Assess your application against the BSC Sandbox eligibility criteria, including whether it:
Is similar to any other existing BSC derogations.
Is likely to be affected/constrained by any upcoming changes to the BSC rules.
Meets one or more Applicable BSC Objectives (e.g. if enabling you to trial your idea will give potential benefits to system operation, competition and/or BSC efficiency).
Creates any risks to BSC settlement accuracy. We’ll consider if any risks can be mitigated through monitoring and/or by applying conditions. This will involve us seeking a view from the BSC’s Performance Assurance Board.
Has any impacts on BSC Parties. This will include us consulting BSC Parties and other interested parties.
Involves any administration costs to Elexon or our service providers, e.g. to undertake manual workarounds or specific assurance activities. This will involve us carrying out impact assessments.
Represents the minimum scope and shortest period needed to trial your idea.
Includes a robust plan to transition back to full BSC compliance when your requested derogation ends, or earlier if your trial fails.
Means that you need to report progress to us on a quarterly/annual basis or some other frequency.
Present this information to the BSC Panel. The Panel will recommend whether Ofgem should approve your BSC derogation. This may involve recommending that Ofgem applies conditions to your derogation, to mitigate any BSC risk or impact. Possible conditions could include placing limits on your trial’s scope or duration.
Submit all of the above information and the Panel’s recommendation to Ofgem for decision.
The BSC allows Elexon to charge you for the costs we incur in administering your derogation. We would only seek to do this if the costs are significant.
If the nature of your trial requires material changes to Elexon’s processes and/or systems, we’ll need to assess any risk to our ability to deliver normal BSC activities and other changes to the BSC. This will form part of our assessment of the impact to us and BSC Parties.
Our consultation documents and reports are always public, but we omit any commercially-sensitive information.
How quickly will I get a decision?
We treat each application individually. The BSC Sandbox application process can take several months to complete.
Ofgem has the ability to occasionally ask us for further information after we’ve sent it our report. This could mean that we need to carry out further assessment and consultation, and/or that the BSC Panel changes its recommendation.
What do I need to do if my application’s approved?
Ofgem will give you a direction letter. This will set out what BSC derogation you’ve been granted, any conditions on that derogation, the applicable time period and what/when you need to report on progress.
You’ll need to keep in regular contact with Elexon and Ofgem during the lifetime of your derogation. This includes sending us the reports and information specified in Ofgem’s letter. If you need to accede to the BSC for your derogation to be effective, then we’ll help you do that.
We’ll publish the progress reports you give us, but with any commercially-sensitive information removed/redacted.
Before the end of your Trial Period, you’ll also need to start preparing to use your transition plan:
If your trial’s successful, and you want to make it a permanent arrangement, you’ll need to propose an enduring change to the BSC rules that’s available to all BSC Parties. This means raising a BSC Modification Proposal. Your derogation may be extended by an extra Transition Period while the Modification’s progressed, but this can’t exceed the overall 3-year time limit on derogations. You should work back from the derogation end date to decide when to raise the Modification, based on its likely complexity and timescales (we can advise on these).
If a Modification isn’t implemented by the end of your Trial Period or any extra Transition Period, then (unless there are exceptional circumstances and subject to the overall 3-year limit) the derogation will expire and you’ll be expected to be fully compliant with all BSC rules.
If your trial’s not successful, you can exit early – otherwise the derogation will expire at the end of the Derogation Period. You’ll then be expected to be fully BSC-compliant. If you no longer want to be a BSC Party, your exit planning could include starting the process of withdrawing from the BSC (but if your derogation’s expired, you’ll still need to be BSC-compliant until this withdrawal process completes).
The BSC Panel may recommend that Ofgem removes your BSC derogation early, if:
You’re in breach of the derogation or its conditions; or
Circumstances have changed materially since your derogation was approved, meaning that it no longer meets the BSC Sandbox eligibility criteria.
What can and can’t the BSC Sandbox deliver?
The table below explains the overall purpose of the BSC Sandbox and its potential outcomes.
BSC Sandbox is:
BSC Sandbox isn’t:
For testing new and innovative ideas in a live market environment
To gather learnings to help inform a Modification Proposal that removes barriers to innovation and opens up the benefits for all BSC Parties
Limited to the minimum scope / timescales needed to test the idea
Something that’s not permitted by normal BSC rules, so conditions may be needed to mitigate any Settlement Risk or impact on BSC Parties
Unlikely to be appropriate if there’s a significant impact, that can’t be mitigated, on one or more of the following:
Intended to support more than one trial of the same (or very similar) idea
A way to bring a full-scale commercial product to market without a Modification Proposal
A guarantee of trial success – learnings from failure are equally valuable and can avoid the industry effort of a wasted Modification Proposal
A guarantee of an enduring rule change (the considerations may be different under a Modification Proposal for an enduring fully-scaled solution, compared with those for a limited trial)
Necessarily a better first route to addressing a barrier to innovation, compared with just raising a Modification Proposal – it depends on what learnings the trial can offer that could help inform a Modification Proposal’s solution
Elexon’s role is to operate the BSC Sandbox process impartially and efficiently. We will support you by giving advice on both the sandbox and Modification processes, as well as on how your idea interacts with the BSC (including what BSC derogation(s) could be needed to enable it). We’re not a partner to, and have no vested interest in the outcome of, any sandbox application, sandbox trial or related Modification Proposal.
