Professional clean energy geek, very average amateur surfer.

Part-time host on the Transmission podcast (down under).

I write about grid-scale batteries and energy markets - longer content on LI, video on YouTube and both on Modo Energy’s terminal.

The state of BESS offtakes in the NEM: Tolls, revenue swaps and PPAs - Research | Modo Energy
Offtake contracts such as virtual tolls provide stable returns for BESS in the volatile NEM. This helps to manage risk and get debt financing.

Although if we add in what's installed but still commissioning in the NEM you do get an extra 2.2 GW and 5.7 GWh which maybe does get you there!

Great article Keira - arbitrage is definitely dominating for big batteries now.

On Australia overtaking the UK, do you have the numbers for this? For commercially operating BESS we have the NEM behind GB, and adding WEM only gets you so far.

But expect this to all change in the next 6-12 months!
