Energy Storage for Commercial Renewable Integration
The Energy Storage for Commercial Renewable Integration (ESCRI) project is examining the role of medium to large scale (5-30MW) energy storage in the integration of renewable energy into the South Australian electricity system.

South Australia has one of the highest usages of renewable energy in the world. Most of this generation is from wind and solar, which is intermittent. The impact of this intermittency becomes more pronounced as conventional generation decreases. Careful integration between these elements within the network is required to ensure stable and reliable power is delivered to consumers under all conditions.
Batteries, flywheels and even compressed air systems can assist networks overcome issues such as peak demand management and can even potentially offset upgrading network components. The inclusion of such energy storage has been studied at a high level by the South Australian Government, which found that it may be a commercial prospect.
This project has evaluated and reported on the potential of an energy storage asset to take advantage of energy from the significant overnight generation at AGL’s South Australian wind farms. The report has outlined the technical, commercial and regulatory issues involved with energy storage system deployment.
Electranet have addressed how the proposed storage system would interact with the electricity networks rules and regulations. Worley Parsons are leading technology selection, along with developing technical specifications, timeline and costs estimates.
The study examined the potential of energy storage to:
- support the National Electricity Market with frequency control services and black-start capability for fossil power stations;
- provide value to ElectraNet’s transmission network through peak load management and/or deferral of potential transmission capital upgrades; and
- allow increased use of renewable generation within the network.
The ESCRI project will be the first time that utility scale non-hydro storage has been assessed in Australia.
The ESCRI project will provide a business case that determines if energy storage is a commercial prospect for integrating intermittent renewable energy into the electricity grid.
If successful, storage could become standard in new renewable energy installations, increasing their competitiveness and potentially leading to more deployment of renewables.
