Queensland’s energy landscape is set for a significant boost with Spanish utility Naturgy Energy Group SA announcing a substantial investment exceeding AUD$489 million in a new large-scale solar farm and battery energy storage system (BESS) on the Fraser Coast. The project, confirmed on 16 July 2026, will integrate 330 megawatts (MW) of solar generation capacity with a 180 MW battery storage system, targeting full operation by 2028.
This major infrastructure development underscores the accelerating pace of renewable energy deployment in Australia, particularly in Queensland, as the nation moves to decarbonise its electricity grid. Construction for the Fraser Coast project is already underway, marking a critical milestone for the state’s renewable energy targets.
Project Details and Strategic Importance
The Naturgy project is designed to deliver 330 MW of solar power, complemented by a substantial 180 MW battery energy storage system. This hybrid approach is crucial for enhancing grid stability and ensuring a reliable power supply, even when the sun isn’t shining. The company has secured a 10-year power purchase agreement (PPA) for the electricity generated, providing long-term revenue visibility, though the off-taker has not been disclosed.
Queensland has been actively pursuing large-scale renewable projects to meet its ambitious energy targets. Projects like the Fraser Coast development are integral to supporting the Queensland SuperGrid, which aims to connect renewable energy generators to demand centres across the state. The integration of significant battery storage capacity alongside solar generation allows for better management of peak demand and more efficient use of renewable energy.
“Australia’s federal government has expanded its National Renewable Energy Priority List by adding 11 new generation and battery storage projects… These projects were identified in partnership with state and territory governments to accelerate planning and environmental approval procedures for renewable energy infrastructure considered nationally significant.”
This project adds to a growing pipeline of large-scale battery storage capacity across Australia, with the federal government actively supporting such developments. Australia now ranks third worldwide for both residential and utility-scale battery storage, trailing only China and the United States, following the commissioning of 4.4 GW of battery capacity in the year to March 2026.
Broader Impact on Australia’s Energy Transition
The investment by Naturgy reflects global confidence in Australia’s renewable energy market and its potential for large-scale solar and storage integration. The Australian Energy Market Operator (AEMO) projects that solar generation and battery storage will dominate the new capacity needed to achieve a least-cost pathway to 2050, with total generation and storage capacity reaching 308 GW. This includes a forecast for dispatchable storage capacity from batteries, virtual power plants (VPP), and pumped hydro to increase eleven-fold from 6 GW to 64 GW by 2050.
While large-scale projects like Naturgy’s are vital, the decentralised growth of rooftop solar continues to be a defining feature of the Australian energy landscape. Over 40% of Australian homes now have rooftop solar, contributing significantly to the country’s overall solar capacity. The increasing abundance of midday solar power has led to lower wholesale electricity prices, and in some instances, near-zero or negative prices, highlighting the need for effective storage solutions and demand management strategies.
For households considering their own energy transition, understanding the role of batteries is becoming increasingly important. Large-scale battery projects contribute to grid stability, which indirectly benefits all consumers, while home batteries offer direct savings by enabling greater self-consumption of solar power.

The federal Cheaper Home Batteries program continues to offer upfront discounts, with the rebate amount reducing every six months from May 2026.
This trend towards increased storage, both grid-scale and behind-the-meter, is critical as solar feed-in tariffs (FiTs) continue to decline across many parts of Australia. Effective 1 July 2026, several major retailers, including EnergyAustralia and AGL, reduced or entirely removed FiTs for some contracts, making self-consumption and battery storage more financially attractive for solar owners.

Naturgy’s AUD$489 million investment signifies a robust commitment to Queensland’s renewable energy future and strengthens Australia’s position as a leader in global energy transition efforts. The project is expected to create jobs during its construction phase and contribute long-term to the state’s energy security and environmental goals.
