Fire Protection & Suppression System
Our BESS integrates a multi-layer fire protection system combining liquid cooling, early detection, and aerosol suppression to minimize thermal risks and prevent fire propagation.
With real-time smoke and temperature monitoring, potential hazards are detected at an early stage, enabling fast system response and effective fire suppression to ensure asset safety and system reliability.
Smoke Detection
High-sensitivity detection identifies early smoke generation at the cell level and triggers immediate system response before flame formation.
Temperature Monitoring
Real-time tracking of temperature rise and hotspot detection enables early risk prediction and targeted cooling intervention.
Aerosol Fire Suppression
Aerosol agents rapidly suppress flames and interrupt combustion reactions, preventing re-ignition without causing secondary damage.

BESS Energy Storage EPC Solution-FAQs
What Is EPC for BESS?
EPC for BESS refers to turnkey project delivery services for Battery Energy Storage Systems. A BESS EPC contractor integrates battery systems, PCS, transformers, EMS, BMS, fire protection systems, and grid connection infrastructure into a complete and operational energy storage solution.
What Is the Difference Between EPC and EPCM?
EPC contractors take full responsibility for delivering a completed project at an agreed price and schedule. EPCM (Engineering, Procurement, and Construction Management) contractors provide project management and technical oversight, while the project owner signs contracts directly with suppliers and construction companies. EPC generally offers lower project risk, while EPCM provides greater flexibility and control.
What Does EPC Mean in Energy Storage Systems?
EPC stands for Engineering, Procurement, and Construction. In energy storage systems, EPC services cover the entire project lifecycle, from feasibility studies and system design to equipment sourcing, site construction, grid connection, and final commissioning.
How Much Does a Battery Energy Storage System EPC Cost?
The EPC cost of a BESS project depends on factors such as project size, battery technology, site conditions, grid connection requirements, and local labor costs. EPC expenses typically include engineering design, civil works, electrical installation, commissioning, permitting support, and project management. Larger utility-scale projects generally achieve lower EPC costs per MWh due to economies of scale.
