AI won’t save a battery portfolio built on bad data

Battery energy storage systems (BESS) are growing faster than the teams managing them. In 2020, Hornsdale Power Reserve was the largest lithium-ion battery installation in the world at 194 MWh. In 2025, the Edwards & Sanborn solar and BESS project clocked in at 3.2 GWh. That’s more than 16 times the capacity, in just five years.
Much of that growth traces back to the volatility renewables bring to the grid. Solar and wind push prices around, create curtailment, and open the arbitrage spreads that batteries exist to capture. Rising data center demand is adding to the pull on new generation, but the core driver is the intermittency itself.
Whatever the energy mix, the batteries being installed are not there only as insurance against downtime. They are commercial assets, measured in real time against contracts that may already be out of date. More capacity, built faster, means more sites per manager, and more places for a silent data error to hide.
The expertise needed to manage systems at this scale is scarce, and AI is being offered as a tool to help stretched portfolio managers keep on top of both maintenance and markets. But the most useful thing AI can do is not produce more analysis — it is to reduce the distance between a developing problem and the person who needs to know about it. And it only works if your data is accurate in the first place.

ACCURE helps companies reduce risk, improve performance, and maximize the business value of battery energy storage. Our predictive analytics solution simplifies the complexity of battery data to make batteries safer, more reliable, and more sustainable. By combining cutting-edge artificial intelligence with deep expert knowledge of batteries, we bring a new level of clarity to energy storage. Today, we support customers worldwide, helping optimize the performance and safety of their battery systems.
ACCURE Battery Intelligence pairs an award-winning battery analytics platform with hands-on performance engineering for grid-scale battery storage. The platform combines artificial intelligence with physics-based battery models to give owners and operators an independent, cell-level view of their assets, and ACCURE's performance engineers work alongside clients to act on it: capturing the revenue their assets were built to deliver, lowering operating costs and mitigating risk. Founded by battery researchers from RWTH Aachen University, ACCURE is the assurance and outperformance layer for grid-scale BESS, supporting more than 24 GWh of capacity worldwide. We work with battery owners and operators, and the insurers and financial institutions that back them, across Asia-Pacific, Europe, Latin America and North America.
