Our report, Insights into Australia’s growing two-way energy system, provides an overview of the evolving role that customer exports have within the electricity distribution networks in the National Electricity Market and the Northern Territory.
It analyses 2023-24 operational and performance data by 14 DNSPs, including: export customer numbers, battery penetration, export limits, capital and operational expenditure, timings of connection agreements and more.
Export service customers are those with consumer energy resources (CER), such as household rooftop solar and batteries, that are too small to be considered generators by the Australian Energy Market Operator (AEMO).
Key findings include:
- 10% of all electricity delivered by DNSPs was sourced from export customers in 2023–24.
- 27% of all network customers now use export services, up from 25% in 2022-23.
- 4% of customers now have batteries, with over 16% of new rooftop solar installations including a battery in 2023-24
- 76% of export customers have smart meters, up from 68% in 2022-23.
- The average static export limit applied to customers was 5.7 kVA, up from 5.5 kVA in 2022-23.
- 0.6% of customers were on static-zero export limits in 2023-24, a slight increase from 0.5% in 2022-23.
- 20% of customers experienced overvoltage in 2023-24, down from 30% in 2022-23.
- 4 DNSPs offered flexible export limits in 2023-24, following successful trials in 2022-23.
- All but two DNSPs offered customers a connection agreement for model standing offers within 3 days, on average.
- DNSPs continued to use only a small proportion (about 1%) of their total expenditure to provide export services throughout the year.
