ACEN Australia’s Stubbo Solar Becomes First LTESA-Backed Project to Reach Full Commercial Operation

ACEN Australia’s Stubbo Solar project has officially reached full commercial operation, becoming the first solar generator backed by a Long-Term Energy Service Agreement (LTESA) to do so and marking a major milestone in New South Wales’ clean energy transition.

Built ahead of the formal launch of the Central-West Orana Renewable Energy Zone (REZ), Stubbo Solar spans two policy periods and now stands as one of Australia’s largest solar developments. The AUS $760 million, 520 MWdc (400 MWac) project was celebrated at an onsite ceremony attended by New South Wales Minister for Climate Change, Energy, the Environment and Heritage Penny Sharpe, alongside Ayala Corporation President and CEO and ACEN Chairman Cezar “Bong” Consing, ACEN President and CEO Eric Francia, and ACEN Australia Executive Chairman Jose Maria Zabaleta.

The milestone underscores ACEN Australia’s growing role in accelerating large-scale renewable energy deployment across the state and the country. “Stubbo Solar reinforces ACEN’s long-term commitment to Australia’s clean energy future. This milestone highlights how clear policy and strong partnerships can unlock large-scale renewable investments. It also reflects the dedication of our ACEN Australia team and partners whose collaboration and hard work turned this project into a powerful example of what’s possible in the energy transition,” said ACEN Australia Executive Chairman Jose Maria Zabaleta.
