Market Overview

An increase in power consumption across the globe is anticipated to drive the demand for mobile ESS during the forecast period. These standalone power devices utilize renewable energy sources for power generation. The mobile energy storage system, or mobile ESS, is capable of enhancing energy resilience in response to severe weather events and associated outage conditions.

Mobile ESS can be self-mobile electric vehicles (light-duty vehicles, vans, or buses) or towable (towable or transportable via semi-trailer truck). Different battery technologies are available in mobile ESS. However, Li-based technology is largely preferred due to its better performance and suitability. Applications of mobile ESS are rising in commercial, industrial, and residential sectors across the globe. Increase in demand for electricity and rise in investments in renewable sources are expected to fuel the demand for the product.

Analysts' Viewpoint on the Global Mobile Energy Storage Systems Market
Mobile energy storage systems can be effectively used during crisis as well as to fulfill demands from residential and commercial spaces. They have been used in EV charging stations, distant construction sites, or outdoor events. It offers economic advantages over stationary storage systems.

Such systems are reliable, cost-efficient, and resilient and they help reduce environmental impacts. Governing bodies are setting the stage for grid-scale deployment by working on an appropriate regulatory framework. The thrust for electric mobility utilizing modern and reliable energy storage would significantly reduce the country's dependency on imported fossil fuels and energy storage system (ESS). Key players in the global market are focusing on R&D in mobile energy storage to increase their global footprint.

Recent Developments in Mobile Energy Storage Systems Market

• In 2025, Jupiter Electric Mobility (JEM), besides mobility, also forayed into mobile energy storage by introducing their own 10 ft and 20 ft containerized battery energy storage systems (BESS) with modular capacities ranging from 241 kWh to 3 MWh for commercial, industrial, and off-grid power applications. These units, completely designed and made in-house, are aimed at diesel generator replacement, solar energy arbitrage, C&I backup, and mobile ESS scenarios. JEM also revealed its 2028 plans to increase its yearly production capacity from 1 GWh to 5 GWh and to export units to Africa, thereby lending a hand to India's clean energy goals.

• In 2025, Volvo Group went public with the PU2000 Battery Energy Storage System, a move that signified a shift from conventional transport manufacturing to integrated energy solutions. The PU2000, made in Sweden, is an intelligent, secure, and cost-effective energy BESS platform that can be deployed flexibly in commercial and industrial operations. It includes smooth integration with Volvo's energy management software, state-of-the-art safety systems such as liquid cooling and fire suppression, and features for peak shaving and load shifting.

• In 2025, Fluence Energy revealed its first domestically manufactured grid-scale energy storage systems delivered in the U.S. The milestone marks a strategic shift toward increasing local production as the company faces robust demand for flexible storage in utility and commercial applications.
