Solar and Battery Owners Face Losses from Proposed Network Tariff Changes
Renewable energy advocates are sounding alarms over plans to modify fixed network costs in electricity bills, warning that such changes could significantly harm many Australian consumers. Those with solar and battery systems, as well as low-income households that utilise minimal electricity, are particularly likely to feel the impact.
The Australian Energy Market Commission (AEMC) has suggested adjusting electricity network tariffs to increase the fixed costs component. This proposal was outlined in a draft review published last December as part of broader reforms in energy pricing.
Understanding Network Tariffs
Network tariffs consist of both fixed and variable costs associated with connecting to the electricity distribution grid. These fees are charged to electricity retailers, who subsequently pass them on to consumers, often composing up to half of the total bill.
The AEMC contends that transitioning to dynamic pricing has benefited some consumers, particularly those who invest in solar energy and adapt their usage based on price signals. However, it has also adversely affected those who cannot modify their usage, such as renters and high-energy users, leading the AEMC to propose a higher fixed tariff that would charge every customer the same fee regardless of their usage levels. They argue this change would help balance the billing structure.
Opposition to the Proposed Changes
Despite these justifications, a recent wave of feedback on the draft review has shown substantial resistance to the suggested reforms, with critics stating this approach could have “serious and far-reaching consequences” for households and overall energy equity.
David McElrea, Chief Advocacy Officer of the Smart Energy Council (SEC), expressed the council’s strong disapproval, indicating that households making efforts to reduce energy costs and emissions would see their initiatives undermined, as a greater proportion of their bills would no longer reflect their actual usage.
In a separate statement, Solar Citizens raised concerns that increasing fixed charges would place undue pressure on households that use little grid electricity, ultimately benefiting the electricity distributors while penalising consumers. CEO Heidi Lee Douglas pointed out that those most affected would be solar and battery owners, as well as energy-efficient households, single-person residences, and apartment dwellers striving to lower their energy expenses amidst rising costs of living.
Impact on Consumers
Research from Green Energy Markets indicates that households equipped with solar systems and batteries could see their annual electricity costs rise by an estimated $400 to $700 due to these proposed changes. GEM analyst Tristan Edis provided an incisive critique, labelling the AEMC’s tariff proposal as a “Robin Hood scheme in reverse.”
Edis highlighted that low-income households tend to consume significantly less electricity compared to their higher-income counterparts, which means the AEMC’s plan could worsen the financial situation for these vulnerable consumers by raising their bills by $127 to $217 depending on their respective networks.
Industry Voices Opposing the Reform
Notable opposition has also come from Tesla, the American electric vehicle and energy firm, which previously stated that static network tariffs represent an outdated model that hinders innovation and consumer engagement. Emily Gadaleta, a senior energy policy advisor at Tesla, remarked that while they back the principles of retail competition and regulation, the current frameworks do not serve the interests of consumers in a future rich in renewable energy.
In a subsequent submission in December 2024, Gadaleta pointed out that Australians are already investing in sustainable solutions to benefit from the energy transition. However, frustrations arise when market regulations do not acknowledge these investments fairly.
Next Steps and Timeline
The AEMC is requesting written submissions regarding the draft document by 13 February 2026. The feedback received will shape final recommendations, which are expected to be released in a report during the second quarter of 2026.
