Sydney’s Renewable Energy Potential

A think tank has proposed that Sydney could transform into a self-sufficient energy city by taking charge of its electricity consumption and production, creating a large renewable energy zone. This innovative approach would position Sydney as the first Australian city to shift from relying on power from regional areas to generating and utilising its energy locally.

The initiative would address the imbalance where regional areas bear the burden of renewable energy production while cities enjoy the advantages. According to the ‘Sydney as a Renewable Energy Zone’ report, the city accounts for nearly half of the state’s total energy demand.

Unlocking Rooftop Solar Potential

If every residential, commercial, and industrial rooftop in metropolitan Sydney were equipped with solar panels, the city could generate up to 21 megawatts of electricity, meeting up to 75 per cent of its energy requirements. Notably, industrial warehouse rooftops could produce over 500 per cent of their electricity needs.

A Vision for a Sustainable Energy City

The report envisions a future where Sydney operates as an almost self-contained energy hub, integrating rooftop solar panels with various battery systems, including home, community, and industrial-scale batteries. These would be coordinated through virtual power plants, leveraging the city’s existing energy distribution networks for collective benefit.

Consulting firm Arup’s Kate West highlighted the pivotal role of cities in driving the energy transition, emphasising the need for coordinated efforts to maximise benefits and cost savings for consumers.

Despite the potential, only a third of Sydney residents currently have solar panels, leaving many excluded from the advantages. Sam Kernaghan from the Committee for Sydney stressed the importance of leadership and collaboration across government levels, regulatory bodies, and industries to facilitate a widespread transition to affordable rooftop solar and storage.

Empowering Communities for Energy Independence

City councils and smaller urban areas have been exploring ways to enhance their energy independence, with some already taking steps to secure their energy needs. The report suggests that Sydney must build on existing state policies to incorporate solar panels and electric vehicle chargers in apartment buildings to advance its journey towards self-sufficiency.

Looking to Illawarra’s urban renewable energy zone as a model, Sydney could explore innovative approaches to integrate consumer energy resources, community batteries, electric vehicles, and industrial requirements.

Efforts to engage all residents, including renters and low-income households, are crucial. The report advocates for community batteries, virtual power plants, and minimum energy standards for rental properties to ensure inclusivity and accessibility.

Driving Sustainable Solutions

The proposal includes community-ownership models for batteries, sub-district-level energy zones linked to local substations, and incentives to accelerate the adoption of solar and battery systems. By embracing these strategies, Sydney could pave the way for a more sustainable and resilient energy future.

As the city navigates towards greater energy independence, collaboration, innovation, and inclusivity will be key to realising a greener and more efficient energy landscape for all Sydneysiders.
