Grids & Integration

Australia’s largest battery with grid-forming inverter capabilities is set to go ahead with energy major AGL announcing a final investment decision on a 500 MW, two-hour duration battery being developed in the New South Wales Hunter Valley.

Smart metering services provider Intellihub is seeking to develop digital infrastructure that will enable the orchestration of more than 150,000 otherwise scattered consumer energy generation and storage devices, helping to create more than 510 MW of flexible energy demand.

Electric vehicle charging in Australia and New Zealand has been given a boost with fund manager Pacific Equity Partners acquiring a majority stake in Australian electric vehicle charging solutions provider EVSE to the tune of $250 million (USD 167 million). The partnership also involves PEP-backed smart metering specialist Intellihub.

The New South Wales government has released the design of a proposed new plan that would give Australia’s energy ministers the power to direct coal-fired and other generators to continue operations if the capacity is deemed necessary to maintain grid reliability and security.

Western Australian government-owned utility Synergy’s plan to build a 500 MW/2,000 MWh battery energy storage system in the state’s southwest to improve system security and support increased renewable energy generation in the main grid has been given the tick of approval by planning authorities.

A “major influx” of new renewable generation and storage capacity is poised to connect to Australia’s main grid with the energy market operator revealing almost 150 projects representing more than 31 GW of new capacity are in the application and pre-registration stages.

Australia’s largest electricity transmission project has hit a snag with a major union alleging transmission line workers delivering the New South Wales stretch of the $2 billion-plus (USD 1.32 billion) Project EnergyConnect electricity interconnector have been working in unsafe and non-compliant conditions.

Victorian network operator AusNet has commenced construction of a transmission network upgrade that is expected to reduce generation constraints and improve network stability in the state’s southwest, unlocking 1.5 GW of additional renewable energy generation capacity.

Redback Technologies has announced inverters certified as compliant with Queensland’s dynamic connections for energy exports. This enables homeowners to export energy back into the grid at a flexible rate so that energy output is only limited in roughly 2% of the time when excess power from PV installations would overwhelm the grid.

Through a co-funding deal with Victoria’s newly revived SEC, Equis Development has reached financial close and begun construction on phase 1 of its giant 1.2 GW Melbourne Renewable Energy Hub. Plans for the hub, which includes gigawatt hours of storage, seem to have shifted somewhat, with phase 1 now three independent batteries of 200 MW with either two- or four-hours of storage.
