Carnarvon Energy Storage Trials

Horizon Power is conducting a cutting-edge energy storage trial at the Mungullah Power Station in Carnarvon.

As part of achieving this broader objective, Horizon Power is conducting a cutting-edge trial over the next 12 months into the benefits of two 1,000 kilowatt batteries housed in two 40 foot containers at the Mungullah Power Station in Carnarvon to explore ways of meeting energy demand at a lower cost.

The batteries will be tested to see if they are capable of rapidly providing energy in the event of a spike in demand or one of the generators at the power station stops running, potentially saving hundreds of thousands of dollars a year in fuel and maintenance costs that would otherwise be used to provide spinning reserve by traditional means.

The batteries were provided by Chinese company, Tianjin Lishen Battery Joint-Stock Company Limited (Lishen), which won an open tender last year. If the trial is successful, Horizon Power will purchase the batteries at the end of the 12 month trial period.

The trial will include testing the batteries in a range of operating modes including spinning reserve, peak shifting and simulation of hosting capacity. The trials are expected to give Horizon Power more information about how it can better support renewable energy installed in Carnarvon with this additional energy storage, however the battery installation will not automatically result in an increase in hosting capacity.

The trial will also enable Horizon Power to access the latest technology of a large-scale battery at a competitive cost, and will gain experience and knowledge in using this equipment in an operating microgrid.

Horizon Power has Australia's largest portfolio of remote microgrids, or isolated power systems, and is exploring ways of incorporating new technologies such as battery storage and new devices which may allow more renewables to be installed. When Horizon Power built the Mungullah Power Station it committed to incorporating renewable energy into this station. The trial is the first step in meeting that commitment.
