Battery energy storage system (BESS) integrator Fluence will use its AI-powered bidding optimisation software Mosaic for 3.64GWh of Akaysha Energy BESS in Australia.
The projects in the Akaysha portfolio, a developer backed by asset manager Blackrock, that will benefit from the partnership with Fluence include the 850MW/1,680MWh Waratah Super Battery, the 415MW/1,660MWh Orana BESS in New South Wales and the 150MW/300MWh Ulinda Park project in Queensland.

Mosaic, which has been utilised in other Australian BESS projects, such as a 100MW/200MWh Tilt Renewables BESS in Victoria and is regarded as the “most widely adopted bidding optimisation software on the National Electricity Market (NEM)”, harnesses AI to enable clean energy asset owners to increase revenue, minimise cost, and manage risk while maintaining compliance with wholesale electricity market rules.
Perhaps the most significant BESS to use Mosaic technology will be the Waratah Super Battery, a previously described ‘giant shock absorber’ system that will enhance reliability and resiliency across the NEM. The first stage of energisation was completed in early September.
One of the world’s biggest BESS assets to date, construction of Waratah Super Battery began in May 2023 and is scheduled to go into operation next August. Akaysha has in place a System Integrity Protection Scheme (SIPS) contract with transmission network provider Transgrid.
Through the partnership, Mosaic will help Akaysha deliver a project that operationally meets the New South Wales government’s needs and puts downward pressure on the cost of these services to the state’s consumers.
Fluence’s Mosaic technology helps assets operate ‘as profitably as possible’
Andrew Kelley, vice-president of APAC Digital at Fluence, exclusively told Energy-Storage.news that the Mosaic technology helps clean energy assets “operate as profitably as possible, even through challenging market conditions like negative prices and grid constraints”.
“Mosaic helps investors and asset owners scale up their portfolios of assets efficiently, without needing to hire extra traders to watch screens each time they commission a new asset. Mosaic takes care of the routine and labour-intensive aspects of energy trading, freeing energy traders up to focus on higher value activities,” Kelley added.
Indeed, the technology’s potential benefits have seen Mosaic’s usage across the NEM surge in recent years. Kelly explains that the technology has over five years of experience and 9GW of assets under management in the NEM, including 18 operational grid-scale BESS. Alongside the NEM in Australia, Mosaic is also used in the CAISO and ERCOT markets in the US.
Kelley stated that Mosaic improves market efficiency in the NEM by ensuring clean energy assets effectively respond to price signals and deliver necessary services at the appropriate times and locations.
“Mosaic interacts with the market by submitting bids directly to AEMO on behalf of market participants. The process automation that Mosaic delivers is critical in a fast-moving market like the NEM, which has 5-minute pricing and no gate closure. Trading a BESS in the NEM would be very challenging without an algorithmic price forecast, SOE planning, and rebidding tool like Mosaic to support human traders,” Kelley said.
