The Economic Regulation Authority has published the second annual report on Western Power’s progress against the final decision on Western Power’s fifth access arrangement (AA5).
As the AA5 review was undertaken during a period of significant change and uncertainty in the energy sector, our decision included areas of special focus for Western Power to progress and increased reporting requirements during the access arrangement period.
We are closely monitoring Western Power’s progress against the requirements of the access arrangement. This monitoring will help to inform preparations for the next access arrangement review (AA6).
This second annual progress report covers 2023/24. As most changes in the AA5 final decision did not come into effect until 1 July 2023, 2023/24 is the first full year for which the access arrangement period has applied.
The report includes data on revenue, expenditure, tariffs, reliability performance, safety and emissions.
