GE to supply 100 MW/300 MWh battery for South Australia solar farm

One of the big PV projects in the South Australian pipeline has named its energy storage supplier. The Solar River Project has selected Paris-headquartered GE Renewable Energy to supply and integrate a 100MW/300MWh big battery alongside a 200 MW PV plant.

In a release on Thursday, GE said its 100 MW, three-hour battery storage system, delivering almost 300 MWh storage capacity, is capable of transferring up to 400 MWh of electricity per day. If built fast enough, the battery will overtake the title of the largest battery system on the Australian grid from the 100 MW/129 MWh Hornsdale Power Reserve. Other even bigger batteries have already been announced, for South Australia in particular.

“The award of the battery to General Electric is another major milestone for the project,” said Solar River Project CEO Jason May. “General Electric brings a cutting-edge technology to South Australia, by delivering huge energy transfer capacity with an intelligent operating system.”

As one of the largest batteries in the Southern Hemisphere, the system will allow the PV plant to deliver firm generation and assist in smoothing peaks. It will contribute to a more stable South Australian grid which is, as GE puts it, characterized by “one of the peakiest loads in the world”.

Prakash Chandra, Renewable Hybrids CEO at GE Renewable Energy, described the Solar River project as a flagship for the renewable energy industry and for GE’s role in building out renewable hybrid plants. “Hybrid solutions have become a reality, driven by the demand for reliable and dispatchable renewable energy, which we can integrate using our proprietary controls technology to optimize asset and customer outcomes,” he said.

The Solar River Project received development approval in June last year and is intended to see the first electricity generated in early 2021. The $450 million project is being developed by former Investec banker Jason May and lawyer Richard Winter near Robertstown.

It was originally announced as a 100% privately funded development with a 60/40 merchant/PPA structure. However, this changed earlier this year when Solar River inked a 15-year offtake deal with Alinta Energy for 75% of its output.

The project is likely to double its PV and battery capacity provided the proposed high-voltage transmission line to Victoria goes ahead. The connection to Victoria would be added to the proposed $1.5 billion electricity interconnector between Robertstown in SA and Wagga Wagga in NSW.

While the  final determination on SA-NSW interconnector is expected sometime before the end of the year, with the proposal now in the latter stages of its Regulatory Investment Test for Transmission (RIT-T), projects have been queuing on both sides of the proposed transmission line. The biggest among them was unveiled last week by French renewable development giant Neoen, comprising 1200 MW of wind, 600 MW of solar and 900 MW of battery storage. The developer said the second and third phases of the Goyder South’s construction can only commence once the interconnector is operational.
