Is the EMS supplied by the container manufacturer?

The container control layer is, but the market optimization layer is typically independent — this allows the aggregator to be changed without replacing hardware.

Does it work without an internet connection?

Yes. Local strategies such as peak shaving and import limiting operate autonomously; loss of connectivity only limits market-facing functions.

Who has access to the data?

The investor has full access to operational data. Service access is role-based and logged.

EMS — energy management system in a BESS installation

Short answer

The EMS decides when the storage system charges and discharges, and it is responsible for 100% of the installation's revenue. Standard integration includes Modbus TCP, IEC 61850, and an API to the aggregator's system.

Peak shaving based on measurement at the connection point
Arbitrage based on TGE price forecasts and the balancing market
Maintaining regulation bandwidth for aFRR / mFRR
Prioritizing the capacity obligation over other revenue streams

Integration with the surrounding environment

The EMS exchanges data with the BMS, PCS, revenue meters, fire safety system, and the investor's overarching control system. Protocols: Modbus TCP, IEC 61850, DNP3, REST API.

Reporting and warranty settlement

EMS data forms the basis for the annual capacity test and for settling capacity and availability guarantees under the LTSA. History is retained locally and in the cloud for a minimum of 10 years.
