Average time to connect to the network: Electricity distribution (RIIO-ED1)


Source: RIIO Electricity Distribution annual report 2017-18.

Information correct as of: March 2019

This chart is an indicator of network operator performance on connections to the electricity distribution network. It shows the average time to connect (TTC) for single service low voltage (LVSSA) connections and small project demand (LVSSB) connections. It compares these to the targets set in 2013.

 Average time to connect to the distribution network: At-a-glance summary

  • Since last year, the average time to connect (TTC) has improved; however, in 2017-18 six out of the fourteen DNOs did not meet the TTC targets we set.
  • Average TTC across LVSSA (Single service LV connection) was lowest for Western Power Distribution and was lowest for Electricity North West Ltd across LVSSB (Small project demand connection (LV)). The average TTC across both connections types was highest for Scottish Power Energy Networks.

Relevance and further info

Under RIIO, each company has to deliver a range of outputs, which they are required to report on each year. This chart provides us with an indicator of network performance against connections.


Each year, network companies must report on their performance under the RIIO-ED1 price control. Our review of their submissions and supporting information informs our annual publications on network company performance.
