First 25MW of Lake Bonney battery should be coming online after the end of the March. That's a little over 11 % of Lake Bonney capacity.
To look at how that might affect overall performance
2018 production sold from LB complex was 348 GWh out of 380 GWh of production. Roughly 91.6% efficiency. Additional 11% capacity should cover all that.
LB provided ~40% of production sold so an additional 8.4% capacity equates to additional ~3.36% on the top line of 2018 numbers.
