Modification: P362

Introducing BSC arrangements to facilitate an electricity market sandbox

Proposer: BSC Panel

Current Phase: Assessment Procedure

Lead Analyst: Lawrence Jones

Category: Governance

Implementation Date: The Workgroup recommend implementation 5 WDs after approval


Appropriate provisions do not exist to enable pre-competitive or proof of concept testing for innovative products/business models in the live BSC Settlement environment. This Modification Proposal seeks to enable the Panel to grant derogation of certain BSC obligations to participants of ELEXON’s BSC sandbox.

P362 is a document only change and is expected to impact only ELEXON as part of implementation. However, we have indicated on this page that P362 will impact BSC Parties and Party Agents, as well as BSC Central Systems. This is because P362 may impact anyone wishing to participate in the sandbox and may impact BSC systems and processes. These impacts will need to be considered on a case by case basis as part of the sandbox application process.


The last Workgroup meeting was held on 7 March 2018. The Workgroup have finalised the solution for Assessment Procedure Consultation, which is planned to be issued in late March 2018.  The third Workgroup meeting was held on 26 February 2018, to review the legal text and Assessment Procedure Consultation questions.

Ofgem confirmed that they would coordinate a common sandbox process across all Code Administrators who would like to participate. Ofgem held a second sandbox cross-Code meeting on 16 February 2018. Ofgem highlighted how ELEXON was taking the lead by initiating its own regulatory sandbox with P362.

ELEXON recommended to the Panel, at its meeting on 9 November 2017, that a Modification should be raised to introduce an electricity market sandbox into the BSC arrangements. The Panel agreed to raise the Modification Proposal in accordance with Section F2.1.1(d)(i).

The Assessment Procedure Consultation has been issued, with responses due by Thursday, 12 April 2018. The Assessment Report will be presented to the BSC Panel in May.
