SunCast 902: Why Most Grid-Scale Batteries (BESS) Underperform - And How to Fix It Before It Costs Millions
Battery storage is scaling fast.
But scaling portfolios exposes weaknesses most owners never see coming.
As projects move from single sites to gigawatt-hour fleets, many IPPs discover something uncomfortable: they have dashboards - but not decision-grade visibility.
In this Episode, Lennart Hinrichs, EVP and General Manager of the Americas at TWAICE, explains what actually changes once batteries begin operating at scale.
We discuss:
- Why state of charge (SOC) is foundational — but insufficient
- How LFP chemistry complicates measurement more than most assume
- What derating really does to revenue and dispatch confidence
- Why overbuild can mask deeper performance issues
- What actually causes most battery fires (and what doesn’t)
- How data transparency reshapes warranty disputes and financial risk
This isn’t a founder story.
It’s a practical conversation for asset owners, operators, and performance engineers who want fewer surprises over the life of their storage assets.
If you operate or finance battery projects, this episode will sharpen how you think about KPIs, safety, and operational confidence.
