MELBOURNE, May 7 (Reuters) - Dozens of companies from 10 countries are vying with Elon Musk's Tesla Inc to install Australia's largest grid-scale battery to help keep the lights on in the country's most wind-dependent state.
The South Australian state government said it had received 90 expressions of interest to set up battery storage by December with about 100 megawatts of capacity for one hour.
Most submissions have been by Australia-based developers in tandem with international energy storage manufacturers, but there have also been numerous other proposals that remain under the radar.
The state government has not yet set a date for when it will announce the results of the tender. Market leader Samsung SDI's batteries could be used by more than one of the bidders. Some of the others in the running are:
- Tesla Inc. Boss Elon Musk in March offered to install $25 million worth of battery storage within 100 days, and offered it for free if he missed the target.
- South Korea's LG Chem, partner undisclosed
- Zen Energy using batteries from U.S. firm Greensmith
- Privately owned Lyon Group with U.S. power company AES Corp
- Carnegie Clean Energy, Lend Lease Corp with Samsung SDI batteries
- Equis Energy, founded by bankers who worked for Macquarie Group's Korea infrastructure fund. Plans to build two solar power plants in Australia.
- redT Energy, vanadium energy storage machine maker working with an undisclosed partner
- Adelaide-based 1414 Degrees has put forward an alternative proposal for a long term grid scale project and is awaiting feedback, its executive chairman Kevin Moriarty told Reuters.
