Battery Energy Storage System (BESS) store large amounts of energy in high-voltage batteries and are integrated with advanced electronics, cooling systems, and safety controls. Because of this complexity, relocation requires specialized procedures to protect both personnel and equipment. Two of the most critical stages in this process are the safe power-down and disconnection of the system and the rigging and transport phase. Each of these steps must be performed with precision to ensure that the system is relocated without damage and can be safely recommissioned at its new location.
Safe Power-Down and Disconnection
Before any physical work can begin, the BESS must be completely de-energized. This step is essential because the system stores energy at voltages and currents that can be extremely hazardous if not handled properly. Our team begins by coordinating with the facility’s operations staff and reviewing all manufacturer-specific shutdown procedures. Each BESS model has its own sequence for shutting down components in the correct order, and following that order is necessary to prevent equipment damage and safety risks.
The first part of this process involves shutting down the Battery Management System (BMS), which is the control center for the entire storage unit. The BMS monitors battery health, manages charging and discharging cycles, and ensures cell balancing. Powering down the BMS halts all energy transfer and isolates the battery banks from the inverter and the grid connection. After the BMS is shut down, we follow lockout/tagout (LOTO) procedures on all electrical circuits to ensure there is no chance of accidental re-energization during the move.
Cooling systems are then addressed. Many BESS units are equipped with liquid cooling or forced-air systems to maintain battery temperature within safe limits. We drain, disconnect, and cap liquid cooling lines to prevent leaks during transport, and we secure fans or other moving parts to avoid vibration damage. Communications cabling is also disconnected and labeled for accurate reconnection later. This includes network lines to the control room, sensors, and monitoring devices.
We also address the system’s fire suppression components. BESS units often include integrated fire suppression systems such as gas-based extinguishing agents or heat detection sensors. These must be powered down and depressurized or disconnected as per the manufacturer’s instructions. All steps are documented with photographs and detailed notes to ensure that reinstallation is efficient and accurate.
In addition to mechanical and electrical disconnection, we take extra care with any residual charge in the system. Even after shutdown, high-voltage capacitors or partially charged battery modules can retain energy. Using appropriate testing equipment, we verify that all circuits are fully discharged before proceeding with handling. This attention to detail ensures both safety and compliance with industry best practices and regulatory requirements.
Rigging and Transport
Once the BESS has been safely powered down and fully disconnected, we move to the rigging stage. This is where heavy equipment handling expertise becomes critical. BESS units can vary in size, but containerized systems often weigh tens of thousands of pounds. Their weight distribution is not always uniform, as internal battery racks, cooling systems, and inverters may be positioned unevenly. This makes understanding the load center and rigging points essential to a safe lift.
Our rigging process begins with identifying the approved lifting points on the enclosure or frame. These points are designed by the manufacturer to bear the weight of the unit without distorting or damaging its structure. We never attempt to lift from unapproved areas, as this can cause frame warping or internal component misalignment. Depending on the site conditions, we may use cranes, hydraulic gantries, or high-capacity forklifts to perform the lift.
If the BESS is a modular design with separate battery enclosures, inverter units, and cooling skids, each module is lifted and moved individually. This modular approach can reduce lifting weights, simplify transport, and make it easier to maneuver equipment through restricted areas. Each module is secured to prevent internal shifting—battery racks, for example, must be braced or locked into place so they do not move and damage wiring during transit.
For on-site relocations within the same facility, we may use specialized air skates or heavy-duty machine skates to move the BESS across the floor. Air skates use compressed air to float the load slightly above the floor surface, reducing friction and the risk of damage to flooring. For moves between facilities or over longer distances, we use lowboy trailers or multi-axle heavy-haul trucks to handle the load safely. Before transport, we use vibration-dampening mounts or blocking to protect sensitive electronics from shock loads on the road.
Securing the load is a critical part of the transport process. Tie-down straps, chains, and blocking are used in accordance with Department of Transportation (DOT) requirements, and the system is inspected before departure to confirm it is stable. Oversized loads may require permits, escorts, and route surveys to ensure bridges, turns, and clearances can accommodate the equipment. We coordinate these logistics in advance to prevent delays and reduce risks during transit.
When moving large, containerized BESS units, environmental protection measures are also considered. We may cover vents and access panels to keep out dust, moisture, and debris. If weather conditions are poor, we use protective tarping or shrink wrap to shield the equipment during transport. These precautions help ensure that the system arrives in the same condition it left.
Equipment Handling and Safety Precautions
Handling BESS equipment requires strict adherence to safety procedures at all times. High-voltage battery modules and associated electronics can be damaged by improper handling, so our team uses rigging gear that is rated well above the expected loads and inspects it before every lift. Lifting is done slowly and steadily to avoid sudden movements that could shift the load or strain lifting points.
Because of the potential fire risk associated with lithium-ion batteries, even when powered down, we maintain fire extinguishers rated for electrical and lithium battery fires on-site during the move. Our team is trained in recognizing the signs of thermal runaway and knows the emergency steps to take if an incident occurs.
We also coordinate closely with the facility’s electrical engineers and safety officers to ensure that every stage of the move meets both the manufacturer’s guidelines and local safety codes. This collaboration is essential to avoid damaging costly equipment or creating hazards that could delay commissioning at the new location.
Documentation for Reinstallation
Throughout both the disconnection and rigging stages, we create detailed documentation to streamline reinstallation. Every cable, pipe, and connection is labeled, and photographs are taken from multiple angles. This record ensures that once the system is in its new location, our team can reconnect and recommission it quickly and accurately.
We also track every piece of equipment moved, including auxiliary systems like HVAC units, transformers, and switchgear that are part of the BESS installation. By keeping a detailed equipment log, we make sure nothing is misplaced or overlooked during reassembly.
