ACEN Australia's recent financial report reveals a significant 87% generation boost in the first quarter, primarily attributed to the successful integration of the Stubbo Solar project and the ongoing expansion of the New England Solar PV plant. This achievement is notable, considering the challenges posed by a 6% decline in average wholesale prices and the impact of Stubbo's commercial operations on the company's earnings.
The Stubbo Solar project, located in the Central-West Orana Renewable Energy Zone, is a groundbreaking initiative. It's the first solar facility in Australia to be supported by a Long-Term Energy Service Agreement (LTESA) and is expected to generate a substantial 900GWh of renewable energy annually. This project's success is further solidified by ACEN Australia's commitment to recycling one million solar modules over its lifecycle, showcasing an advanced approach to end-of-life management for utility-scale solar installations.
The New England Solar project, which began operations in March 2023 with an initial 400MW capacity, is now being expanded to 720MW. A 200MW/400MWh battery energy storage system (BESS) is being co-located at the site, supplied by Energy Vault and featuring grid-forming inverters. This BESS is 87% complete and is expected to be fully operational by mid-2026, providing system strength and network security services.
The New England project's success is partly attributed to reduced curtailment, which has been linked to the growing number of large-scale battery storage systems in NSW providing a price floor during daytime hours, according to Australian Energy Market Operator (AEMO) assessments. New England also avoided much of the network curtailment that affected solar PV plants in the southern parts of the state due to grid capacity constraints.
Despite the growth in generation, ACEN noted that results reflected lower merchant prices and higher depreciation and interest expenses following Stubbo's commercial operations. The company's earnings grew 59% to P994 million, at a slower rate than generation and revenues, largely due to growing depreciation and interest costs associated with the completed project.
ACEN Australia's contracted capacity stood at 33% in Q1 2026, down from 38% in Q1 2025, as the completion and ramp-up of Stubbo increased available output ahead of contracting. The company has stated its objective is to steadily increase contracted capacity now that Stubbo is fully operational.
In conclusion, ACEN Australia's impressive generation boost in the first quarter is a testament to the successful integration of the Stubbo Solar project and the ongoing expansion of the New England Solar PV plant. Despite challenges, the company's commitment to renewable energy and advanced end-of-life management strategies positions it as a leader in the Australian energy sector.
