Every C&I storage system produces a continuous stream of operational data — quarter-hour power and energy, cell-level voltages and temperatures, state of charge and health, alarms and events. That data is not a by-product of the asset; it is an asset in its own right. It is the evidence base for your warranty claims, the input to your revenue settlement, the audit trail for your insurer and your investor, and the foundation for any future participation in capacity markets, flexibility services or a virtual power plant. An owner who treats data as something that lives in the vendor’s cloud is giving away an asset and calling it a convenience.
In the Netherlands, Germany and Belgium, what the asset earns — or is charged — is increasingly settled on time-granular data. The Dutch congestion contracts behind large batteries, the Belgian capacity tariff that charges by peak capacity, and Germany’s evolving net-tariff regime all hinge on metered, time-stamped data. If that data lives only in the vendor’s platform and cannot be exported in a standard format, then the owner cannot independently verify what they are being paid, or charged, and cannot arbitrate a settlement dispute. Ownership of the data is ownership of the economics. Require raw, timestamped export in an open format, on demand, with no per-export fee.
A virtual power plant aggregates many small assets into one tradable resource. Your storage system can only be aggregated if its data can be streamed, securely, to a third-party aggregator — which means the data interface must be open, not locked to the vendor’s own platform. A vendor that controls the only API to your asset controls whether you can ever participate in a VPP, and on whose terms. Locking the data is a quiet way of locking the future revenue.
When the asset underperforms and you claim on the warranty, the claim is won or lost on data. The vendor will want the operating history; so will your insurer. If the data was never exported, or was only in the vendor’s platform where it could not be independently inspected, you have lost the ability to prove your case. The warranty is only as strong as the data that can substantiate it — which is the same lesson as the O&M guide: a warranty without the data to enforce it is a warranty without teeth.
Own it — the contract must state the owner owns the operational data, not a licence to view it. Export it — require raw, timestamped, open-format export on demand, and test that export before signature, not after. Never let it live only in the vendor’s cloud — mirror the data to your own storage continuously, so that contract termination, insolvency or a platform shutdown does not take your history with it. A storage asset is a fifteen-year commitment; the data should live as long as the asset does, and it should live with you.
