The Aldoga solar farm is a 380MW solar photovoltaic (PV) project developed by ACCIONA Energía in Queensland, Australia.
Construction work on the facility commenced in April 2024, and it was completed in April 2025, seven months ahead of schedule.

The solar farm achieved full commissioning and began commercial operations in December 2025. The project entailed an investment of A$670m ($445m).
At the height of construction, the project employed up to 350 people. In the operational phase, it supports around 15 full-time positions.
Aldoga solar farm can generate sufficient electricity to meet the annual needs of almost 185,000 homes. The solar farm is expected to have an operational life of 30 years.
The project is expected to avoid roughly 934,000 tonnes of carbon dioxide emissions each year, which is equivalent to removing 360,000 combustion vehicles from the roads.
Aldoga solar farm location
The Aldoga solar farm is located about 20km north‑west of Gladstone in the foothills of Mount Larcom in central Queensland.
The solar PV facility occupies land inside the Gladstone State Development Area, established by the Coordinator‑General, on parcels prepared by Economic Development Queensland (EDQ).
The EDQ initiative is designed to revitalise underused state land, creating local jobs and supporting economic growth.
Project development background
In April 2018, EDQ selected ACCIONA through a competitive procurement process to develop and operate the Aldoga solar farm under a 30-year land lease agreement.
The Queensland Coordinator-General approved the initial development application for a 250MW project in May 2019.
In November 2020, ACCIONA submitted a State Development Application Material Change of Use to the Coordinator-General at the Department of State Development, Tourism and Innovation to enable a larger solar farm using additional land, increasing proposed capacity from 250MW AC to 480MW.
The Queensland Government approved a Material Change of Use application to expand the Aldoga solar farm in July 2021.
Aldoga solar farm details
The Aldoga solar farm development spans an area of 1,137 hectares and is fitted with up to 818,144 bifacial double-glass mono solar modules installed on Nextracker XTR single-axis trackers.
Each panel, around 4m high, tracks the horizontal movement of the sun to optimise renewable energy production.
A system of above-ground cabling connects each panel while an underground cable network links the panels to a power conversion unit, which converts the power to electricity for transmission.
The project is equipped with 81 transformer substations with INGECON SUN 3Power C Series inverters.
The solar farm is connected to the National Electricity Market via the Powerlink Larcom Creek Station.
Power purchase agreement
In October 2023, the state-owned energy firm Stanwell entered into a 15-year power purchase agreement with ACCIONA Energía to acquire all output from the Aldoga solar farm.
Project financing
In March 2025, ACCIONA Energía arranged an A$453m syndicated loan to finance the construction of the Aldoga solar project.
The financing was obtained through Cesce, the Spanish export credit agency, under its green investment framework.
The facility was provided by four banks: Banco Santander, BNP Paribas, ING and JP Morgan.
Banco Santander acted as Cesce’s agent while ING served as the environmental, social and governance coordinator.
Contractors involved
The solar panels for the Aldoga solar project were procured from JA Solar. These panels were manufactured in China.
Nextracker supplied the Nextracker XTR single-axis trackers and collaborated with Australian tube and pipe manufacturer Orrcon Steel to manufacture critical components for the trackers.
Pilecom, a local solar energy system service, implemented the Nextracker XTR single-axis trackers.
In May 2024, ACCIONA Energía appointed Ingeteam to provide the power-conversion and control equipment for the project. Ingeteam supplied 81 power stations incorporating 157 INGECON SUN 3Power C series central PV inverters.
GenusPlus Group was engaged by ACCIONA Energía to design and build the 275kV substation for the project.
All Energy Contracting was involved in civil works, mechanical installations and related works while Enertis Applus+ carried out solar quality assurance and quality control services on the bifacial photovoltaic modules of the Aldoga solar farm.
