Customer interruptions and minutes lost: Electricity distribution (RIIO-ED1)

Chart

Javascript is required to render chart Customer interruptions and minutes lost: Electricity distribution (RIIO-ED1).

This chart is an indicator of the reliability and availability of the electricity distribution network. It shows the number of interruptions experienced by customers and the average length of interruptions.

We update this chart on an annual basis. Click the ‘more information’ tab above for a summary of the latest trends, details of how to interpret the figures and for information on methodology.

More information

Relevance and further information

Distribution network operators invest in their network to increase reliability and resilience against severe weather and to protect the network from the effects of climate change.
We incentivise distribution network operators to improve the reliability on their network, penalising underperformance and rewarding those who beat their targets.

Methodology

We set annual targets for customer interruptions and customer minutes lost. Each year distribution network operators must report on their performance under the RIIO-ED1 price control. This allows us to assess if targets have been met and to reward or penalise network operators appropriately.
