Apr 13, 2023 · The ACT will take another big step towards securing electricity supply reliability as energy markets decarbonise with a deal to build a $400 million battery energy storage system
Aug 20, 2025 · Canberra, AUSTRALIA – 6 November 2024 – Global energy storage specialist, Eku Energy today announced reaching Financial Close for its Williamsdale Battery Energy
Jul 9, 2024 · On 13 February, when freak winds brought down a transmission line in Victoria and shut down the state''s largest power station, a fleet of electric cars plugged into a charger in
Nov 22, 2024 · The large-scale 250megawatts (MW) battery will store enough renewable energy to power one-third of Canberra for two hours during peak demand, providing long-term energy
Nov 22, 2024 · Positioned within the Evoenergy distribution network, the start of construction is a significant milestone for the ACT''s commitment to a net-zero future. The large-scale
The battery will also provide a range of energy and essential system security services. In exchange, the Territory will provide Eku Energy with fixed quarterly payments over a period of 15 years. The Big Canberra Battery project is delivering an ecosystem of batteries at different scales.
With the capacity to store enough renewable energy to power one-third of Canberra for two hours during peak demand periods, the project is a crucial component of the ACT government’s Big Canberra Battery initiative. Eku Energy has established an innovative revenue swap arrangement with the ACT government, ensuring mutual benefits for both parties.
This 250-megawatt (MW), 500 megawatt-hour (MWh) battery energy storage system (BESS) is part of the Big Canberra Battery project and can store enough renewable energy to power one-third of Canberra for two hours during peak demand periods. The BESS will cost between $300 and $400 million and will be developed, built, and operated by Eku Energy.
Batteries can store excess renewable energy to be used at later times of higher demand - thereby extending the benefit of renewable energy into the evenings. It will increase the renewable energy hosting capacity across the ACT enabling more Canberrans to access the benefits of renewables.
Released 13/04/2023 The ACT Government is future-proofing Canberra’s energy supply by expanding its renewable energy storage with a new partnership with global specialist energy storage business, Eku Energy, launched by Macquarie’s Green Investment Group.
The Williamsdale battery energy storage system (BESS) will deploy Tesla Energy’s Megapack technology and will connect to Evoenergy’s electricity distribution network. The facility will be installed south of Canberra to provide fast-acting frequency control and ancillary services to the grid.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
