Battery Energy Storage for Low-Carbon AI Data Centres: How MPMC HBD-A Systems Work With Generators and Solar

AI data centres combine very high power density with demanding uptime targets and ambitious carbon commitments. Battery energy storage helps on all three fronts: it responds in milliseconds to protect critical loads, shifts solar energy into the evening, reduces peak demand and lets standby generators run less often. MPMC's HBD-A Series is engineered for this role, and because MPMC also builds the high-end containerised generator sets used in data centres, it can design storage and generation as one coordinated system.

Four Roles for Storage in a Low-Carbon Data Centre

UPS-Level Response and Ride-Through

Integrated with the generator array, HBD-A storage provides UPS-level millisecond response, supporting critical loads instantly while generators start and synchronise. Its grid-forming, VSG and black start capabilities let the battery establish and stabilise site power independently, and on-grid/off-grid switching is supported on every model, with seamless switching available as an option.

For AI clusters whose power draw can change quickly as workloads ramp up and down, this fast response helps hold voltage and frequency steady for IT and cooling equipment.

Peak Shaving, Grid Services and Solar Shifting

The EMS charges the battery at off-peak times and discharges it during peak demand, lowering the maximum kW drawn from the grid, while frequency regulation capability allows participation in grid services where markets permit. Paired with rooftop or campus PV, HBD-A stores surplus midday solar and releases it later, raising the share of renewable energy in the facility's supply. DC-coupled HBD-DC 410 and HBD-DC 5000 models suit large solar-plus-storage installations.

Less Generator Running Time

By covering short events and peaks from storage, HBD-A reduces reliance on standby generator running time while maintaining zero-downtime availability, cutting fuel use and emissions from routine operation.

Engineered for High-Density Critical Sites

HBD-A systems use LFP 314Ah cells rated for 8,000 cycles at 90% depth of discharge, liquid cooling on every model, IP67 battery packs within an IP54 system and CE-certified aerosol fire protection, operating from -20°C to +55°C. The largest unit, the HBD-1000-2000, delivers 1,125 kW from 2,170 kWh. In the 8 MWh system MPMC delivered to Europe, each HBD-1000-2000A uses a dual-PCS parallel architecture with 45 CATL LFP battery packs and nine high-voltage cabinets in a full-weld 20HQ container with C4 coating, ceramic-based aerogel insulation and IP55 protection. Safety features include aerosol suppression in every pack, smoke, temperature and humidity alarms, and BMS-EMS linkage with automatic power cut and remote alarm.

Storage and Generation From One Supplier

MPMC's data-centre generator set references include a 3 MW MTU-powered installation and the 12 MW Changhang Power Station in the UAE and 36 MW of backup power in the US. Its self-developed SCADA coordinates generator sets, storage and PV with real-time monitoring, automated reports, ten years of data retention, an SL3-level cybersecurity framework and Starlink satellite backup communication.

The same platform can monitor generator sets, HBD-A storage and solar arrays across multiple sites with hierarchical account management, giving operators of several data centres a single view of their energy assets. Remote diagnostics and on-site commissioning by MPMC engineers support each installation from start-up onwards.
