Naturgy to Build 330MW Solar and 180MW Storage in Queensland, Australia

en.Wedoany.com Reported - Spanish energy group Naturgy Energy Group announced on July 16 that it will invest over €300 million (approximately $344 million) in Queensland, Australia, to build a hybrid renewable energy complex comprising a 330 MW solar power plant and a 180 MW battery energy storage system. The project aims to enhance the stability and long-term energy security of Queensland's power grid through the synergy of storage and generation.

The core function of the facility is to utilize the 180 MW battery energy storage system to absorb excess electricity during peak solar output and rapidly release it during peak demand periods, achieving near real-time supply-demand balance. This configuration helps smooth out fluctuations in solar output caused by cloud cover or day-night cycles, alleviating the pressure of the "duck curve" on the grid. Additionally, the battery inverters can provide frequency and voltage support functions, maintaining stable grid operating conditions during periods of high renewable energy penetration. During high-load periods such as evenings, stored electricity can be dispatched to reduce the risk of supply shortages, and by minimizing curtailment and alleviating grid congestion, it enhances overall operational efficiency.

Naturgy stated that upon completion, the project will add reliable renewable energy capacity to Queensland, supporting the state's clean energy goals. By converting variable solar power into dispatchable resources, the project helps the power system recover more quickly after disturbances, reduces extreme price volatility in the wholesale market, and provides a more stable foundation for grid planning. During the construction phase, the project is expected to create jobs and strengthen local infrastructure, while after commissioning, it will help reduce reliance on short-term backup generation, solidifying Queensland's position as a primary destination for solar investment.
