Panel of Technical Experts

The Panel of Technical Experts (PTE) is an advisory group of independent consultants who were appointed by government to perform a specific and technical function as part of the first Electricity Market Reform delivery plan process.

Role of the panel

The Panel of Technical Experts (PTE) is an independent advisory group, members of which are appointed by government to advise on technical aspects of Electricity Market Reform. The role of the panel is a technical function and not a forum for policy commentary or for advising the government on its objectives for the capacity market or wider policy issues. They have a particular focus on providing scrutiny of the analysis in National Grid’s annual Electricity Capacity Report (ECR), which provides a recommendation on the target capacity for capacity market auctions. A report with their findings is published annually following the publication of the ECR and the Secretary of State’s decision on the target capacity.

The Panel’s Terms of Reference

The terms of the reference for the PTE make clear that Panel members are independent and do not act as representatives of any current or previous employers, trade associations or membership organisations.

The work of the Panel is confidential. The Panel must not discuss or disseminate information which is provided in confidence, or discuss its role, with parties other than those stated in the Terms of Reference. Following publication of the Panel’s reports, the Panel may discuss the content publicly, but must not disclose any information beyond that which is published.

In the contractual terms and conditions, Panel members and the Chair are obliged to inform the Department of Energy Security and Net Zero of their interests and any potential or real conflicts of interest up front and any changes to them, as they occur. Registers of interests for each of this year’s PTE members are available here.
