Interruptions Incentive Scheme

Introduction

The dataset provides detailed information about UK Power Networks' unplanned fault reporting under the Ofgem Interruptions Incentive Scheme (IIS).

It includes key characteristics such as:

• Date/time fault start/end
• Number of customers affected
• Restoration stages
• Cause and main equipment involved
• Status of fault in terms of its exclusion from the IIS scheme due to it being a one-off /severe weather fault

More information about the IIS can be found on Ofgem's website or this document: RIIO-ED2 Regulatory Instructions and Guidance – Interruptions

Methodological Approach

• Source: IIS returns post application of Ofgem decision one status of fault in terms of its exclusion from the IIS scheme due to it being a one-off /severe weather fault
• Manipulation: Includes all rows from unplanned fault reporting IIS returns with calculation of CI/CML removed, leaving source data only i.e. no calculated fields
