Review of the Performance Assurance Framework

ELEXON is currently undertaking a review of the Performance Assurance Framework. This page tells you about the review and provides the latest update on progress.

Latest news

Risk Evaluation Register

The new Risk Evaluation Register is now published. It will be effective from 1 April 2019. Webinars introducing the Risk Evaluation Methodology and the Risk Evaluation Register are up on YouTube for anyone who wants to learn more about the BSC risk management approach. The Risk Operating Plan – how the PAB intends to mitigate risk in the year – will be approved this month.

Review of the Assurance Techniques Workstream

The first technique, Technical Assurance of Metering (TAM), was reviewed and the findings presented to PAB in February, who approved the recommendations. These proposals will now be taken forward – contact the TA Metering team for any questions. Work is ongoing to review the BSC Audit, Supplier Charges and Qualification/Re-Qualification Performance Assurance Techniques (PATs).

Data Provision Workstream

A paper was delivered to the February PAB meeting, presenting the work done to date and including an assessment of current data available for the PAF. Proofs of concept are being developed around additional data sources that could be obtained, and current sources that are underutilised.

Risk Visualisation Tool

An online risk visualisation tool has been developed to help BSC parties identify where settlement risks occur in BSC processes. In addition, it contains basic information about each risk. At present, the tool only applies to the SVA market, however it is due to be expanded to include CVA risks. We welcome your feedback on the tool to risk@elexon.co.uk.

Coming soon

Review of the Assurance Techniques Workstream

We expect to report our recommendations to the PAB in May for the BSC Audit and Supplier Charges. We will issue information about future Issue 69 Working Group engagement on the techniques so that you can be involved.

Data Provision Workstream

We are continuing to assess alternative data sources through proofs of concept. This will allow us to test the specific data items and ascertain how useful and usable they might be, as well as test our systems and processes. We expect to need your contribution on the options through the Issue 69 workgroup.

Key aims of the review

  • Better engagement with parties about issues that do and don’t matter to them (their risk appetite)
  • Increase the quantity and quality of participation in consultations
  • Meet the current and future assurance needs of the Panel, the PAB and the wider electricity industry e.g. smart metering, alternative business models, CVA risk
  • Improve the measurability of Settlement error and the mitigating effect of assurance activities
  • Deliver a valued and trusted assurance service to BSC Parties under the strategic and tactical guidance of the BSC Panel and PAB

The review is projected to run to Q2 2020.

Approach

A core ELEXON team, supported by risk management and data experts, will deliver the review in four workstreams. Industry experts signed up to the Issue 69 working group will be called upon to review and comment on key approaches and proposals.

The PAB will be the primary decision making body, and will receive regular updates on the project’s progress.

The four workstreams will culminate in a revised framework, a new set of risks with estimated error, a refreshed set of mitigating techniques and improved reporting. This proposed framework will be implemented via the BSC Change process where required, after PAB and Panel approval.  Any improvements that can be made sooner will be progressed as necessary.

Workstream 1 – Smart Metering Rollout

To provide immediate assurance against the challenges of the smart metering rollout by developing Proof of Concepts to enable the effective monitoring of significant Settlement Risks associated with the rollout.

This workstream has now completed.  We identified a set of related Settlement Risks; we developed a report on the production and submission of Meter Technical Details (MTDs); we held an industry day; and we handed over management of the risks to the operational teams.

Workstream 2 – PAF Procedures

To deliver recommendations to improve the operability and effectiveness of the REM and other PAF procedures that ensure that risks are more meaningful and reflective to participants.

This workstream has reached its conclusion, having discussed with the Issue 69 workgroup:

  • How risk areas should be identified
  • How these risks should be evaluated, including the workgroup’s endorsement of a new measurement approach
  • How ELEXON could achieve greater engagement with PAF stakeholders
  • How the identified risks should be evaluated in the future
  • Some examples of the proposed PAF design in use

The PAB approved the recommendations on 27 September 2018.

Workstream 3 – Review of the PATs

This workstream will assess, in light of feedback received on the PAF, if there are any gaps in the current set of mitigating assurance techniques (using the new Risk Evaluation Methodology and risk register to identify gaps in risk mitigation), which techniques are cost effective for the level of risk they mitigate, and which techniques are not.

It will then produce a set of recommendations for retaining, altering, adding or removing techniques.

This workstream will also consider the general working practices that ELEXON and the PAB adopt in relation to coordinating and applying the techniques.

Workstream 4 – Data Provision

To create Proofs of Concept to test the viability of alternative methods of data provision that place less burden on participants to provide data and that supports more accurate risk appraisal.

As well as this webpage, we will use Newscast and the OSMs to provide key information and how you can get involved. The Issue 69 webpage holds documents related to that group’s work.

We will also be attending BSC and external forums to present on the objectives and activities of the review. If you would like us to present to your forum, please email us at pafreview@elexon.co.uk.

What is the Framework?

Around £1.7bn in transactions went through the BSC Settlement systems in 2016/17. BSC Parties require an assurance framework that allows them to have confidence in the accuracy of the allocations of energy and charges.

The current approach to the Performance Assurance Framework (PAF) was introduced in 2007 under Modification P207.

With 16 assurance techniques, over 200 identified Settlement Risks, an annual central cost of around £3m, and impacts on all BSC Parties (plus their agents and BSC Agents/systems), the PAF must be delivered in an effective and efficient way.

Why review the PAF?

After 10 years of live operations, and some significant industry changes such as smart metering and innovative business models, the BSC Panel considered the PAF should be reviewed and included it in its strategic forward work plan 2016/17.

ELEXON initiated a project and the Panel approved the preliminary scope and approach at Panel 255 in July 2016.

ELEXON then engaged with a broad spectrum of stakeholders to validate the scope and approach for the design phase of the review. The Performance Assurance Board (PAB) endorsed these proposals and Panel approval was gained in March 2017 (PAB 264/07 – PAF Review Scope and Approach Approval).
