3 Mobile Battery Energy Storage Trends from Bauma 2025 

At Bauma 2025, the world’s largest construction trade show, the conversation around energy storage pushed past traditional limits and revealed new mobile battery energy storage trends. Temporary power challenges are evolving—and so are the solutions. POWR2 was proud to showcase the POWRBANK line of mobile Battery Energy Storage Systems (BESS) in Munich this year, but even more exciting were the forward-thinking ideas we heard from contractors, developers, and project managers around the world. 

Here are three new use cases where mobile BESS is changing the way companies power their work: 

1. Solar-Powered BESS for Off-Grid Construction

A European company is using industrial and utility-scale solar plants to charge modular BESS units, then deploying them at remote construction sites to deliver clean, efficient energy. Once deployed, the power is sold to contractors and end-users for lighting, equipment, and site operations. This model enables off-grid construction projects to finish on time and within budget, all while meeting sustainability goals. 

2. Electrified Jobsites: Mobile Charging Hubs for BEM 
With electric heavy machinery becoming increasingly popular, mobile BESS units are stepping in as flexible charging solutions on jobsites. Instead of transporting equipment off-site for charging, contractors can now recharge battery electric machinery (BEM) on-site with a pre-charged BESS unit—saving time, simplifying logistics, and keeping operations emissions-free. 

3. Powering High-Speed Rail Development 
High-speed rail corridors often start in areas far from utility infrastructure. Mobile BESS is proving invaluable during both the construction and commissioning stages—powering everything from heavy equipment to critical system checks, long before substations and overhead lines are activated. 

Meeting the Moment with Mobile Battery Energy Storage

These emerging mobile battery energy storage trends from Bauma reinforce that mobile BESS is more than a backup plan. It’s a forward-thinking solution for a more efficient, sustainable future. At POWR2, we’re excited to work with the companies who are building the future, today.
