A battery storage system made with second life EV batteries has been developed by carmaker Toyota and Japanese utility company Tokyo Electric Power.

The Australian government is funding grid inertia measurement trial at the Victorian Big Battery, aiming to develop real-time, accurate assessments of the status of the network.

Another serving of news in brief from around the world in energy storage.

A lithium-ion battery energy storage system (BESS) engineered to be installed underwater will be paired with small-scale wave energy converters in a trial supported by the US Department of Energy (DoE). 

A Tesla battery energy storage system (BESS) pilot project has gone into service at what is currently the world’s biggest single-site solar PV plant, Mohammed bin Rashid Al Maktoum Solar Park.

A five-year long project to trial the use of energy storage at community-scale in a Western Australian suburb achieved an 85% reduction in consumption of energy from the grid at peak times for participating households. 

Batteries will be mounted on electricity poles across the low voltage distribution network and aggregated as a virtual power plant (VPP), in a project which will trial their ability to integrate more renewable energy in two regions of Victoria, Australia. 

Batteries can offer a cost-effective option for upward and downward reserve to the UK grid, a project run by AI and automation tech firm Arenko with transmission network operator National Grid ESO has found.

Battery software company Arenko has teamed up with National Grid ESO to provide upward and downward reserve flexibility in a “first of its kind trial”.
