Energy storage | Hithium milestones
Among projects recently reported by China- based stationary battery manufacturer Hithium were a 140 MWh facility in Meizhou City, Guangdong, and a 200 MWh installation in Heze City, Shandong, both employing LFP (lithium iron phosphate) battery technology.
For Meizhou City, Hithium served as core supplier to China Southern Power Grid Company. It was that company’s first 100+ MWh level standalone energy storage project. Hithium describes the facility as a “demonstration project“ and “the world’s first
to be fully supplied with immersion liquid- cooling energy storage”, making it a “milestone application of Hithium’s safer, more efficient liquid-cooling technology.”
Construction took just four months, from start to a trial operation.
The Heze City installation consists of 198 MWh of LFP battery storage plus 2 MWh of VRB (vanadium redox). To meet “continuing demand from large-scale energy storage projects”, Hithium says it is expanding its production capacity to 70 GWh per year by the end of 2023.

Wärtsilä and AGL complete 250 MW battery in Australia
Wärtsilä and AGL Energy report completion of construction at the Torrens Island grid scale battery energy storage system (ESS) in South Australia. The 250 MW/250 MWh lithium–ion ESS installed at Torrens is the second- largest operational battery in Australia, after the Victorian Big Battery, 300 MW/450 MWh (but soon to be dwarfed by the Waratah Super battery under construction in New South Wales, 850 MW/1680 MWh). The Torrens Island battery system will operate in grid-following mode, transitioning to grid-forming mode (virtual synchronous generation – VSG) later. This “groundbreaking feature”, says Wärtsilä, means it the largest energy storage installation to date capable of operating in VSG mode, enabling fast response times and future-proofing operations for the Torrens Island facility. The battery
system is supported by Wärtsilä’s advanced GEMS power plant controller.
AGL chief executive officer, Damien Nicks said, “This is a significant milestone in AGL’s
transition journey as we continue to accelerate the build out of up to 12 GW of renewable and firming capacity by 2035, playing our part in Australia’s energy transition…This battery was constructed within 18 months – a great example of what can be achieved when government, regulators and the private sector are all working together.”

Delta’s new LFP battery targets MW-scale market
Delta has announced the launch of an outdoor LFP (lithium-iron-phosphate) battery system specifically designed for MW level energy storage applications. The offering, says Delta, addresses the urgent need for grid ancillary services, solar plus storage, and backup power assurance. The lithium-iron battery system is provided pre-assembled with battery modules, power, and control equipment. It complies with IEEE 693 seismic certification and IEC 60721-3-2 transportation standards, facilitating transportation by truck and eliminating the need for multiple shipments and on-site battery assembly, thereby reducing the risk of project
delays due to weather conditions at outdoor construction sites, asserts Delta. “As energy storage systems become increasingly familiar in the market, efficiency and safety are growing concerns for owners,” says Paul Ai, Delta’s senior director of energy system solutions business department. “The newly launched LFP battery system features compartmentalised design, fire-resistant casing, variable frequency energy-saving air conditioning, cooling systems, and sensors. It incorporates multi-layer safety protection and management, aligns with international safety regulations, and meets battery protection

requirements, effectively reducing the risk of accidents.
“Delta understands the challenges and risks involved in MW-scale energy storage system deployment. This battery system not only addresses on-site installation issues but also enhances the overall system’s safety, ensuring smooth operation from design and construction to maintenance.”
The Torrens Island ESS is the latest Wärtsilä project in support of Australia’s decarbonisation goals. The company has previously supplied a 211 MW balancing power plant for AGL, the Barker Inlet power station, also located on Torrens Island (see photograph, left). In addition, Wärtsilä is delivering a 460 MW/920 MWh battery, in partnership with Origin, at the Eraring coal-fired power plant power site to support grid security and reliability in New South Wales.
