As reported by Energy-Storage.news last week, Tesla’s energy division gross margin declined 19% in the second quarter of 2026; however, Tesla deployed 13.5GWh of its utility-scale Megapack and Powerwall residential systems across Q2, which was its second-highest quarterly deployment on record.
When combined, Stages 1 and 2 will deliver a 454MW/1,814MWh asset at the Goyder site, adjacent to ElectraNet’s Bundey Substation.
Both stages are supported by 15-year capacity contracts awarded through South Australia’s inaugural Firm Energy Reliability Mechanism (FERM) tender.
Indeed, South Australia’s first FERM tender awarded agreements to six battery storage projects totalling 1,334MW/5,336MWh in May 2026, with Neoen securing two of the six FERMAs, one for each stage of Goyder Battery, each carrying a committed power output of 75MW and 600MWh of storage capacity, against a combined nameplate of 400MW/1,600MWh.
The mechanism requires projects to provide 8-hour dispatchable capacity during periods of system stress, targeting operational dates of November 2028.
