Gentari, a market leader in lean energy solutions, began work on the Maryvale Solar & Energy Storage project (Project Maryvale). The groundbreaking of Project Maryvale is an important step towards the provision of stable, low-carbon energy to New South Wales (NSW).
Project Maryvale is a next-generation hybrid renewable energy power plant that combines a 243 MWp solar installation with a 172 MW/409 MWh battery energy storage system (BESS). Once operational, the facility is expected to provide up to 172 MW of dispatchable clean electricity, sufficient to power approximately 82,000 homes each year, while reducing up to 615,000 tonnes of carbon emissions annually. During peak construction, the project is projected to create up to 360 jobs and support opportunities throughout the regional supply chain.
“Project Maryvale represents our commitment to accelerating Australia’s energy transition with reliable, dispatchable renewable energy,” said Claire Elkin, Head of Gentari Australia. “As one of the first large-scale DC-coupled solar and storage projects in the country it embodies our ambition to deliver clean energy solutions at scale while supporting grid resilience.”
Secured under NSW’s Electricity Infrastructure Roadmap
The project secured a Long-Term Energy Service Agreement (LTESA) under the NSW Government’s Electricity Infrastructure Roadmap. Managed by ASL as NSW Consumer Trustee, the LTESA offers financial security through an energy price floor option, lowering project risk and enabling financing.
Positioned strategically within the NSW Government’s priority location for accelerated development of renewable energy, the Central-West Orana Renewable Energy Zone (REZ), the site is advantaged by quality solar resources and infrastructure to support large-scale generation.
Maximising the Value of Green Energy
The Maryvale Solar & Energy Storage system will make the grid more efficient and stable by providing dispatchable renewable power, smoothing its solar output, and providing power during peak demand periods. The system is also capable of offering necessary ancillary services that are important for ensuring grid reliability, making the BESS a strategic resource for energy supply and grid performance.
Leading Deployment of DC-Coupled Hybrid Solutions
Project Maryvale is one of Australia’s largest DC-coupled solar and battery hybrid projects under development. By enabling solar power to charge the BESS directly, the DC-coupled design facilitates smoother, scheduled delivery of electricity and also optimises the efficiency of renewable energy integration.
Social Impact and Local Engagement
Gentari is committed to delivering long-term value to the local Maryvale community. Initiatives involve creating a community benefit fund, investing in workforce and industry training, and investing in regional infrastructure and housing projects in partnership with local authorities.
Reaching out to First Nations communities, local firms, educational institutions, and government partners strives to achieve inclusive engagement and develop partnerships based on trust, transparency, and mutual benefit.
Project Maryvale adds to Gentari’s Australian clean energy portfolio, which now totals 814 MW of solar and solar hybrid projects installed or under construction nationwide. PCL Construction’s Solar Division is the EPC contractor, and PV modules and the BESS system are purchased directly from Tier 1 suppliers: Trinasolar for solar modules and Contemporary Amperex Technology Australia Pty Ltd for BESS. Notice to Proceed was issued in January 2025, and the construction is in progress.
