Malaysia's clean energy solutions provider Gentari marked the groundbreaking of the Maryvale solar and energy storage project last Wednesday, representing a key milestone in delivering reliable, low-carbon energy for New South Wales (NSW). The project is a next-generation hybrid renewable energy facility that integrates a 243 MWp solar installation with a 172 MW/409 MWh battery energy storage system (BESS).

Project Specifications and Capacity

Once operational, the Maryvale facility can deliver up to 172 MW of dispatchable clean electricity, enough to power around 82,000 homes annually. The project will help avoid up to 615,000 tons of carbon emissions each year. Project Maryvale stands as one of the largest direct current-coupled solar and battery hybrid projects under construction and represents a significant step forward in the integration of renewable energy and storage technologies.

The DC-coupled solar and storage configuration allows the project to maximize excess solar generation by directly charging the BESS while delivering smoother, scheduled generation. The system will support reliable renewable energy by enhancing grid stability and efficiency, offering dispatchable renewable energy by firming its own solar output and dispatching it into the grid when it is most needed. Additionally, the system can provide essential ancillary services, which are critical for maintaining grid stability.

Economic Impact and Employment

At the peak of construction, the project is expected to create up to 360 jobs and unlock local opportunities across the regional supply chain. Project Maryvale was awarded a long-term energy service agreement (LTESA) under the New South Wales government's Electricity Infrastructure Roadmap. Administered by ASL as the NSW Consumer Trustee, the LTESA provides financial certainty through an option of an energy price floor. This mechanism helps to de-risk the project and facilitate financing.

Strategic Location and Grid Integration

The project is strategically located within the Central-West Orana REZ – one of the priority zones identified by the NSW Government to accelerate renewable energy development. This region offers strong solar resources and is designed to accommodate large-scale generation and supporting infrastructure. The Maryvale solar and energy storage system will support reliable renewable energy by enhancing grid stability and efficiency.

The BESS functionalities position it as an asset not only for project economics but for overall grid resilience. As one of the first large-scale DC-coupled solar and storage projects in the country, it embodies Gentari's ambition to deliver clean energy solutions at scale while supporting grid resilience.

Construction Timeline and Contractors

Notice to proceed on the construction of this project was given in January 2025 and construction on site is now underway. The project is being delivered by PCL Construction's Solar Division, appointed as the EPC contractor. The PV modules and BESS system are being free-issued through direct procurement from Tier 1 suppliers — Trinasolar for the solar modules and Contemporary Amperex Technology Australia Pty Ltd, a globally recognized original equipment manufacturer (OEM), for the BESS.

Community Engagement and Benefits

Gentari is committed to delivering lasting value to the local Maryvale community. This includes establishing a community benefit fund, investing in workforce and industry capability development, and supporting regional infrastructure and housing initiatives in collaboration with local authorities. Through ongoing engagement with First Nations communities, local businesses, education providers, and government stakeholders, Gentari aims to foster inclusive participation and build long-term partnerships based on trust, openness, and shared benefit.

Portfolio Expansion

Project Maryvale adds to Gentari's clean energy portfolio in Australia, which now includes 814 MW of solar and solar hybrid projects installed and under construction across the country. Claire Elkin, Head of Gentari Australia, stated that "Project Maryvale represents our commitment to accelerating Australia's energy transition with reliable, dispatchable renewable energy. 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."
