Overview

Neoen is a long-term owner and operator of its assets, described as one of the world's leading producers of exclusively renewable energy. In Australia it has been accelerating the energy transition for over a decade, contributing over 5 GW of renewable energy assets representing an investment of more than $9 billion, and has recently launched operations in New Zealand.

History

Neoen has been accelerating Australia's energy transition for over a decade. By August 2023 it had reached 3.3 GW of capacity in operation or under construction in Australia, consisting of 2 GW of generation capacity evenly split between solar and wind farms and 1.3 GW / 2.8 GWh of battery storage, and had invested more than AUD 4 billion. In July 2022, its 150 MW / 193.5 MWh Hornsdale Power Reserve in South Australia secured approval from AEMO to deliver inertia services, becoming the first big battery in the world to deliver grid-scale inertia services. In October 2024, its Collie Battery Stage 1 in Western Australia, a 219 MW / 877 MWh battery, began operating and delivering grid reliability services under contract with AEMO. The company has recently launched operations in New Zealand and intends to continue expanding its growth in this region.
