Distribution utilities shine a spotlight on resilience
In February, six distribution network service providers (DNSPs) across New South Wales, the Australian Capital Territory, Tasmania, and Northern Territory published a collaboration paper on network resilience. The aim of the paper was to seek views on how best to support communities in tackling the resilience challenges the networks were likely to face over the next 10 years.
The paper highlights that, while Australian DNSPs have improved their System Average Interruption Duration Index performance, there is an increasing trend in the number and scale of major event days that are excluded from reported reliability performance. The paper was particularly geared to seeking ideas in advance of the timetable for developing plans for the next regulatory control period, which will determine revenues for all six DNSPs from 2024-2029. The DNSPs will use the feedback to help inform their approach to the next regulatory period and beyond.
Western Power publishes five-year investment plans – On February 1, Western Power, which owns and operates the distribution grid for Western Australia, released its application for investment required to deliver services to customers over the next five years.
A number of themes are driving Western Power’s proposed investment, including maintaining overall network reliability but improving underperforming hotspots, modernizing protection, ensuring control and visibility of network operation and performance, and supporting more renewable connections. Overall, its proposals would result in a reduction of company revenues, but at the same time distribution capital expenditure is expected to rise by 34%.
The Economic Regulation Authority will now review Western Power’s proposals, which will be subject to public consultation. A final decision is due in March 2023.
