Battery storage is getting cheaper, but the data used to trade and operate it may be badly wrong. When forecasts miss, penalties stack, warranties get messy, and returns can quietly unravel.

My guest is Ash Vats of 3E, who works on battery intelligence for utility-scale assets. We look at the gap between what a battery management system reports and what the hardware can actually deliver - a gap with direct consequences for grid reliability, revenue and asset life.

We examine why some battery sites show faults before day one, how state-of-charge estimates can be materially wrong, and why operators - not traders alone - need to shape commercial decisions. We also unpack what changes when owners, asset managers and traders stop working from three different versions of the same asset.

Listen now to understand what is really limiting battery storage returns, and how better operational intelligence can recover capacity, reduce commercial risk and improve long-term performance.
