Equis Australia (Equis) has reached financial close and commenced construction on the Calala Battery Energy Storage System (BESS), a 250MW/500MWh BESS, located in Tamworth, New South Wales (NSW).
Calala BESS will be instrumental in supporting New South Wales’ renewable energy targets. With a power capacity of 250MW and an energy storage capacity of 500MWh, Calala BESS has enough power to supply electricity for up to 115,000 homes during peak periods.
Calala BESS is expected to be fully operational by 2027 and is located approximately 5.8km southeast of the Tamworth town centre.
Equis secured a $260 million non-recourse senior debt financing package from Westpac, Societe Generale, and Sumitomo Mitsui Banking Corporation for Calala BESS, marking the first merchant BESS debt financing in New South Wales and a significant milestone for NSW’s renewable energy transition.
Calala BESS is structured as two independent projects:
- A 100MW/200MWh portion underpinned by a long-term offtake agreement with Smartest Energy for 100% of its capacity.
- A 150MW/300MWh merchant BESS utilizing Autobidder, Tesla’s real-time trading and control platform. The Autobidder agreement includes a revenue share and a minimum revenue guarantee.
Calala BESS will contribute to diversifying the local economy, creating up to 170 jobs during construction and up to 7 jobs during operations. It will be connected to NSW’s electricity grid via an underground cable to the 330kV Tamworth Substation.
“The Calala BESS will be instrumental in supporting New South Wales’ renewable energy targets while also providing critical firming and frequency support services to the National Electricity Market (NEM), enabling greater integration of renewable energy for Australia.”
David Russell, Co-founder and Managing Director at Equis.
“Calala BESS has contracted Tesla to provide 138 Tesla Megapacks, Consolidated Power Projects (CPP) to deliver the engineering, procurement, and construction (EPC) of the balance of plant, and Transgrid to complete the connection into the Tamworth Substation. We’re proud to be delivering the project in partnership with experienced and highly regarded counterparties, each with a proven track record of delivering complex infrastructure projects on time and within budget across Australia.”
Mahesh Reddy, Managing Director and Head of Equis Australia.
Equis’ experienced in-house planning and communications team has been engaging with the Tamworth community since 2022, which has been crucial for the project’s success.
“Our experienced in-house planning and communications team are committed to thorough and transparent community engagement. This approach is reflected in our team’s ability to secure development approval for our projects at an average of 5 months, which is significantly faster than the industry average. These are our fundamental principles that guide our community engagement so that we invest in renewable assets that will support Australians and local communities for generations to come.”
Mahesh Reddy, Managing Director and Head of Equis Australia.
Through a Voluntary Planning Agreement (VPA), Calala BESS will contribute $2.0 million to the Tamworth Regional Council, and Equis will continue to work closely with the council throughout the entire asset lifecycle to develop initiatives that will support the Tamworth community.
