UK Power Networks Secondary Site Utilisation
Listed in ukpowernetworks
Introduction This dataset shows the utilisation band of our secondary sites across our three networks, over 1 April 2024 to 31 March 2025.
Description
This dataset is a redacted version of an annual regulatory submission to Ofgem. The data consists of a single utilisation value over a year for each of UK Power Networks secondary substation.
This dataset is redacted in that any secondary sites with five or less customers will not be included to protect privacy. This dataset is a mixture of actual utilisation data and analytics based on transformer profile. The utilisation bands do not indicate contractually committed capacity e.g. capacity on our network may be unused now but expected to be used by a connection in a future year, recent acceptances which will be covered in next year's data.

Methodological Approach UK Power Networks worked with other DNOs and the Energy Networks Association (ENA), to agree a methodology to calculating transformer utilisation. It considered the following: Transformer rating; Current peak loading; Year demand growth; Year ahead peak demand; and Utilisation calculation.
Quality Control Statement This dataset is provided "as is". Assurance Statement The Open Data Team and DSO Network Strategy Team worked to ensure data accuracy and consistency.
