Regulated electricity lines businesses provide information to us as part of their disclosure requirements. We then publish a summary and analysis of this information on our website.
The summary and analysis of disclosures is intended to promote greater understanding of the performance of individual regulated suppliers, their relative performance, and the changes in performance over time.
This information helps people to better understand how the sector is performing.
Financial information is a key part of the suite of disclosures that electricity distributors make publicly available. Following the first adjustments to distributors' revenue limits in 2015, we assessed the profitability of each distributor to help people better understand how the sector is performing.
In 2013 electricity distributors, for the first time, publicly disclosed self-assessments of the maturity of their asset management practices. These assessments use the asset management maturity assessment tool, or AMMAT.
