en.Wedoany.com Reported - Akaysha Energy's Orana battery energy storage system in New South Wales, Australia, has reached full output of 415 MW/1660 MWh and has begun dispatching in the Australian National Electricity Market.

The four-hour storage facility is located in the Central-West Orana Renewable Energy Zone near Wellington, New South Wales, adjacent to TransGrid's 330 kV regional substation.

The project's revenue structure adopts a hybrid model: 200 MW of capacity is tied to EnergyAustralia through a 12-year virtual transmission agreement, a synthetic arrangement where EnergyAustralia assumes the financial risk of dispatch decisions while Akaysha retains market registration and actual operational control; the remaining 215 MW of capacity is co-optimized in the energy and frequency control ancillary services of the Australian National Electricity Market.

Akaysha Energy, owned by BlackRock, operates multiple large-scale battery projects in Australia and has international development experience through its parent company. The virtual transmission structure of the Orana project—where approximately half of the asset's capacity is locked in through contracts and the remainder is exposed to the electricity market—is becoming a reference model for financing large-scale battery energy storage systems in Australia. Akaysha is currently promoting this model internationally, having announced a 500 MW, 2 GWh energy storage project in Germany earlier this year.
