en.Wedoany.com Reported - Wärtsilä has announced that the 150MW/300MWh Bungama Battery Energy Storage System (BESS), developed for Revera Energy in South Australia, has entered commercial operation.
The project enhances South Australia's ability to manage record levels of renewable energy while supporting grid reliability in the National Electricity Market (NEM). The Bungama energy storage system can precisely respond to rapid grid fluctuations, including changes in solar and wind output. South Australia often operates with the world's highest levels of variable renewable energy generation, making advanced energy storage infrastructure critical for maintaining energy stability and reliability.
The first phase of the Bungama energy storage system completed its commissioning testing phase ahead of schedule and passed three consecutive Hold Point Tests rapidly. This enabled the project to transition smoothly from commissioning to full commercial operation as required by the Australian Energy Market Operator (AEMO). Hold Point Tests are part of AEMO's commissioning approval process, allowing new energy assets to progress in stages from limited operation to full commercial output, with each step verifying safe and reliable performance.
Revera CEO Daniel Kim stated that the Bungama BESS is a cornerstone asset in Revera's strategy to build the flexible infrastructure needed for Australia's clean energy future. He noted that collaboration with Wärtsilä and project partners demonstrates what effective teamwork can achieve in meeting the grid's high technical and safety standards.
Don Lee, Vice President of Global Operations for Wärtsilä Energy Storage, said that delivering the first phase of this energy storage system in one of the world's most dynamic renewable energy markets showcases what can be achieved with advanced technology and deep system collaboration. The project demonstrates how energy storage can be rapidly deployed to support regions at the forefront of the energy transition, helping stabilize the grid and providing safer, more reliable energy for local communities.
The core technology of the project is Wärtsilä Energy Storage's GridSolve Quantum High Energy (HE) technology, featuring an advanced safety architecture and high energy density design. The co-located site is coordinated by Wärtsilä's GEMS platform, which fine-tunes operations in real time and delivers fast frequency response with millisecond precision.
Wärtsilä worked closely with AEMO, transmission network service provider ElectraNet, and Balance of Plant (BOP) contractor Enerven to ensure safe transport, high-quality engineering, and a streamlined commissioning process in one of the world's most demanding grid environments.
