Performance Assurance Committee

The Performance Assurance Committee (PAC) is an annually elected body of representatives from UNC parties.
The PAC has two constituencies: 9 elected Shipper representatives and 3 Transport representatives.

  • The Transporter constituency is 2 large Transporters and 1 Independent Gas Transporter (IGT).
  • The Shipper constituency has representatives from organisations across all markets

The PACs role is to act as a responsible and independent body to oversee the Performance Assurance regime in the UNC.

  • The PAC meet monthly toDiscuss areas of industry performance,
  • Review risks identified by industry that impact the success of the performance assurance regime and
  • Hear progress of those Parties that have been subject to the PACs Performance Assurance Techniques.
  • Decide on actions required to mitigate risks to settlement accuracy.

The PAC consider:

  • External factors potentially impacting performance
  • Industry concerns on operational difficulties
  • UNC requirements and their contribution to settlement accuracy
  • The accountability of Parties in ensuring the overall settlement landscape remains accurate through meeting UNC obligations.

The PAC are supplemented by monthly reports which are called PARR reports (performance Assurance report registers)

  • These look at a variety of performance targets across industry as set out in the UNC.
  • The PARR reports suite can be added to or reviewed at any point in order to keep the data reported on fresh and relevant. To find out more about PARR reports click here.

The PAC manages risks to settlement through a risk register and a risk evaluation tool which in turn drives the steer of the PAC into specific areas of concern.

The area of the UNC which contains all Performance Assurance related information is TPD V (General) Section 16 (Performance Assurance) and can be accessed on the Joint Office website here.

The PAFA is commissioned through a competitive tender process, carried out by the Central Data Service Provider (CDSP) and terms can last anywhere between two-four years. Gemserv have held the position of PAFA since the regime’s inception in 2017.

This is the industry an opportunity to feed into the regime and aids the PAC in creating their annual forward workplan for the next year.

In 2022, we will be hosting an industry engagement session which will give parties an overview of the

  • Regime within the gas landscape,
  • Deep dives into areas of current priority and
  • An opportunity for direct feedback via an anonymised platform.

The Performance Assurance Framework document (PAFD) is the document at the heart of the regime and sets out the responsibilities of the PAC, PAFA and CDSP.

It also includes the ways in which the PAC can incentivise the industry to improve performance including Performance Assurance Techniques.
