An off-grid hybrid power project under development in Australia is to be supported by a battery energy storage system.

The Coober Pedy Renewable Hybrid Power Project, located in a small mining town in South Australia, is being developed by off-grid power provider Energy Developments Ltd (EDL) and supported by an A$18.5m grant from the Australian Renewable Energy Agency (ARENA).

When completed, the installation will combine power generation from diesel gensets with solar and wind.

According to the project plan, the existing 3.9 MW diesel-fired power station is to be upgraded in order to integrate a 1 MW solar array as well as 4 MW of wind power.

In addition, EDL has now ordered a 1 MW containerized battery energy storage system (BESS) from Toshiba for integration into the project. According to Toshiba, the BESS will provide contingency support to maintain power system frequency stability when the gensets are not operating, and may also provide energy storage or load on demand when the gensets are being run in ‘droop’ mode. The BESS may also be used to allow for block shifting of excess renewable energy, the firm said.

EDL aims to eventually replicate the project at other off-grid locations in Australia.
