BW ESS, a battery energy storage developer, has completed the purchase of the Yanco battery energy storage system from ACEnergy, an Australia-based renewable energy developer. The project, located in the Riverina region of New South Wales, is rated at 250 MW and 1,000 MWh of storage capacity.

Project Details and Timeline

The Yanco BESS is described as a ready-to-build project, meaning the development groundwork has already been completed ahead of construction. BW ESS has indicated plans to bring the facility online by 2028, positioning the project within Australia's growing pipeline of large-scale storage infrastructure intended to support grid stability as the country transitions away from fossil fuel generation.

Transaction Background

The seller, ACEnergy, is an Australian renewable energy developer that had advanced the Yanco project to a stage suitable for acquisition by an infrastructure-focused buyer. The Riverina region of New South Wales, where the project is sited, has emerged as an area of interest for energy storage investment given its proximity to transmission infrastructure and renewable energy zones in the state.

Strategic Context

Large-scale battery storage projects of this scale — combining significant power output with four-hour duration capability — are increasingly central to efforts by grid operators and developers to firm up variable renewable generation across Australia's National Electricity Market. A 1,000 MWh facility at 250 MW represents one of the larger storage projects in the New South Wales development pipeline. BW ESS's acquisition signals continued international investor interest in the Australian storage sector, where policy frameworks and capacity market mechanisms have drawn capital from developers and infrastructure funds seeking long-duration, grid-connected assets.
