Pacific Energy has been awarded a contract by Territory Generation to deliver utility-scale battery energy storage systems (BESS) with a total capacity of 33.5MW/81MWh across the Alice Springs and Darwin-Katherine power systems in Australia’s Northern Territory. The contract is the next phase of Territory Generation’s Battery Energy Storage System Program, which aims to enhance grid stability and enable higher solar penetration in the region’s isolated power networks.
Pacific Energy will be responsible for the full scope of work, including the design, manufacture, supply, installation and integration of the BESS at Territory Generation’s power stations in Alice Springs and Katherine, supported by a 10-year service agreement from its local Darwin-based team established in 2022. The BESS will provide essential frequency and voltage control services for both power systems. In Alice Springs, it will also enable energy shifting to support system stability and capacity management during peak and minimum demand periods, addressing challenges in isolated grids with growing renewable penetration.
Pacific Energy CEO Mike Hall stated that the contract reflects the Northern Territory’s renewable energy ambitions and the company’s expanding capabilities in complex grid infrastructure. He added that the project marks an exciting new chapter for the company in the region and its long-term partnership with Territory Generation, describing it as a vote of confidence in Pacific Energy’s ability to deliver large-scale, resilient grid-stabilising solutions.
The projects will be delivered in collaboration with key technology partners, including ABB for inverter systems and Chinese battery manufacturer Narada for battery supply. They build on Pacific Energy’s prior work supporting Territory Generation, including programming and integration for the first 35MW/35MWh Darwin-Katherine BESS with grid-forming inverters. The contract extends Pacific Energy’s track record in delivering renewable energy and storage solutions for isolated Australian power systems.
The company previously delivered Australia’s first off-grid solar-plus-storage plant (26MW, including a 3MW/6MWh BESS) to power Tronox’s Atlas-Campaspe mine in New South Wales, and completed a 61MW solar-wind hybrid installation with a 13MW grid-forming BESS for a Western Australian gold mine last year.
