Valent targets battery projects in Australia

Valent Energy plans to invest over A$2bn ($1.32bn) to develop and operate almost 1.6GW of utility-scale battery energy storage systems (BESS) across Australia, with the first projects coming on line by the end of 2025.

The company, a new joint venture between Asian private equity firm Gaw Capital Partners and Singapore-based BW Group, has seven battery and one solar photovoltaic (PV) projects, with three of the planned storage systems fully approved and finalising contracts to start construction.

The 240MW Mornington unit in Victoria is expected to become operational by the third quarter of 2025. It will be followed by the 250MW Pine Lodge project in the same state and the 120MW Apsley system in New South Wales (NSW), Valent told Argus on 25 January.

Three other BESS projects — the 225MW Gould Creek in South Australia and the 200MW Tamworth and 120MW Armidale units in NSW — are expected to secure connection approvals during 2025. A 550MW solar PV and 400MW storage project in Merriwa in NSW could come on line in 2028, with a final investment decision projected for 2026.

All planned batteries will have two-hour storage capacity, although some of them might get upsized, Valent told Argus. This will take the whole portfolio to a combined storage capacity above 3.2GWh.

The project pipeline comes mostly from Australian renewable energy firm Maoneng, in which Gaw Capital Partners acquired a majority stake in the end of 2022. BW Group will be involved in the joint venture through its subsidiary BW Energy Storage Systems, which has a portfolio of more than 1.5GW of batteries in the UK and Nordic countries.

"With the rollout of substantial government policy to support battery projects, and the record periods of negative prices during daytime solar floods, the moment could not be timelier to build large-scale batteries," said Valent chairman Oliver Yates, a former chief executive of Australian government agency Clean Energy Finance.

Investments in BESS projects have been increasing rapidly in Australia and are expected to receive a further boost from the federal government's Capacity Investment Scheme.

Average electricity generation from batteries in the National Electricity Market — which covers east Australia — increased by 21MW from a year earlier to 47MW in the fourth quarter of 2023, the Australian Energy Market Operator (Aemo) said in its Quarterly Energy Dynamics Q4 2023 report.

"Due to the increased occurrence of negative prices throughout the quarter, as part of their energy arbitrage earnings, batteries received higher payments for charging during negative priced intervals," Aemo said.
