The Maryvale Solar Farm, combining a 172 MW solar PV installation with a 172 MW / 372 MWh battery energy storage system, has secured a long-term energy service agreement in NSW’s fourth tender under its Electricity Infrastructure Roadmap. This project supports the state’s ongoing transition away from coal-fired power.
New Projects Awarded in Aussie State’s Energy Roadmap
The projects were selected during the fourth round of the state’s Electricity Infrastructure Roadmap, a tender launched last November to contract 3,000 GWh of new generation capacity. Only two projects were chosen, and both will receive Long-Term Energy Service Agreements (LTESAs) that protect them from future price risks.

AEMO Services, the NSW Consumer Trustee responsible for the tenders, confirmed the selected projects include a wind farm nearing commissioning and a hybrid solar project with a battery energy storage component.
“Alongside the four long-duration storage infrastructure projects that have also received support, significant strides are being made in advancing NSW’s forthcoming energy system,” said AEMO Services’ executive general manager, Nevenka Codevelle.
“These two projects are valuable additions to an already robust pipeline of supported projects throughout NSW,” she said. “However, it’s evident that securing additional investments, potentially at or near record levels through 2030 and beyond, is crucial to achieving our targets and ensuring a dependable supply of cleaner, more affordable electricity for NSW consumers.”
Gentari Renewables Australia to Develop the Solar Farm
The first project is the Maryvale Solar Farm and Battery Energy Storage System, set to be developed by Gentari Renewables Australia, a subsidiary of Malaysia’s state-owned energy company, Petronas. The project, located near Wellington, is scheduled to begin operations by 2028.
The second project selected is Iberdrola’s 140 MW Flyers Creek Wind Farm. Developed by the Spanish renewable energy company, this wind farm has already completed construction and is set to commence operations this year.
NSW Plans 12 GW Renewable Generation and 2 GW Storage
As New South Wales transitions away from coal-fired power, the state is driving private-sector investment to install at least 12 GW of new renewable energy capacity and 2 GW of long-duration storage. To put this in context, the state’s third Long-Term Energy Service Agreements (LTESAs) tender allocated 750 MW for wind and solar projects and 524 MW for long-duration energy storage—all slated to be operational by 2028.
Gentari Renewables’ Maryvale Solar Project marks a key milestone in this transition. Backed by a long-term energy agreement, the project underscores NSW’s commitment to reducing its dependence on coal and building a cleaner, more sustainable energy future. With its expanding renewable generation and storage capacity, the state is on track to meet its ambitious energy goals and create a greener, more resilient electricity system.
