Power Up Connect has introduced the MBESS 90 kWh, recognized as the world's first International Fire Code compliant Mobile Battery Energy Storage System. This milestone represents the result of a three-year collaboration between Power Up Connect and Dominion Energy and was officially unveiled at CES 2025 in Las Vegas, Nevada. Currently, the MBESS 90 kWh is the only MBESS to achieve UL 9540 listing and is now available for commercial purchase.
The MBESS 90 kWh (patent pending) has a 30 kW maximum output built to be the ultimate dispatchable mobile energy solution, designed to meet energy needs anywhere, anytime, in any conditions. It is light enough, at under 5,000 pounds, to be towed by even mid-sized SUVs and can be safely deployed throughout communities due to its UL9540 and UL9540A certification. It includes 1,100 watts of solar panels which can be expanded to 15,000 watts with an additional solar array for battery charging for fully off grid deployments. Combine that with the capability to daisy chain up to ten units for a combined 900 kWh of capacity and the possible applications are endless. And due to its range of output options it can be used to power anything from a standard 120 VAC appliance to electric vehicle charging. "We built the MBESS 90 kWh to meet the highest standards. From safety, to reliability, to mobility, we know that people will be relying on our system to get them the energy they need in places where there are no other options. It has to work, and our MBESS system delivers," stated Scott Calhoun, COO and President of Power Up Connect.
Dominion Energy, one of the largest utilities in the US, sponsored the development of the MBESS 90 kWh to further diversify emergency response capabilities and meet energy needs, especially in those moments when energy is least accessible. The technology has the potential to provide quiet, mobile, emission free energy for industries ranging from festivals to food trucks, weddings to remote work sites, even powering remote location filming and outdoor entertainment.
"The UL certification has been the key to ensuring that our corporate customers can use this system in public settings. That's what your fire marshals and permitting offices are looking for to approve a battery system of this size as the energy solution for those types of deployments," explained Mwamburi Mkaya, MBESS 90 kWh project director. "Before this system, it's been the wild west out there in the battery world. There are several options available, but all of them were developed before any standards were in place. Our partnership with Dominion Energy gave us the insight to develop a system that meets the highest safety standards and can be deployed in almost any industry that requires mobile energy."
The MBESS 90 kWh is the cornerstone of the Power Up Connect mobile energy lineup. It will be manufactured in the US at the Power Up Connect facility in Baltimore, Maryland and is available now.

Technology group Wärtsilä has successfully completed large-scale testing of its proprietary Active Ignition Mitigation System (AIMS). AIMS is engineered to mitigate potential flammable gas build-up during an abnormal thermal scenario within battery energy storage systems (BESS). With this milestone, Wärtsilä becomes one of the first BESS integrators to demonstrate the effectiveness of an integrated explosion control system.
In July, Wärtsilä conducted a series of three rigorous full-system tests in the United States. Each test simulated worst-case thermal runaway scenarios within Wärtsilä’s Quantum2 containerised BESS enclosure. During the tests, a flammable gas blend, representative of UL 9540A CATL 306Ah cell-level testing, was released at multiple internal locations over a two-minute period. The tests were witnessed by a major US-based utility, a fire alarm vendor, and a third-party consultant. Across all three tests, AIMS successfully prevented uncontrolled deflagrations and structural deformations, allowing the Quantum2 system to remain fully intact with no compromise to enclosure integrity. The tests validated the system’s ability to maintain safety and functionality under extreme conditions.
“AIMS is more than just a technical upgrade – it represents a paradigm shift in energy storage safety,” said Mishaal SyedNaveed, Product Manager, Fire Protection at Wärtsilä Energy Storage. “We believe true safety starts well before gases build up as a result of thermal runaway. With AIMS, we are pioneering technology to help our customers manage BESS risks before they escalate.”
Advancing beyond reactive containment, Wärtsilä’s AIMS technology takes a pioneering approach by deliberately igniting flammable gases before they accumulate. AIMS uses sparker systems in combination with door-mounted deflagration panels to safely ignite flammable gases at the earliest stage of a thermal event. This early intervention prevents significant off-gas build-up and reduces the likelihood of deflagration panel activation.
“This test is a first-of-its-kind in the industry, and a powerful testament to the leadership of our fire safety experts,” said Tamara De Gruyter, President of Wärtsilä Energy Storage and Executive Vice President at Wärtsilä. “We’re not only rethinking how storage systems are built, we’re also actively collaborating with first responders, emergency personnel, customers, consultants, and other stakeholders to engineer a robust system and best equip our partners to act when it matters most.”
During the testing, Wärtsilä collected visual, temperature, static and dynamic pressure, and UV/IR data, which will be used to continue the company’s commitment to energy storage innovation and community safety. These rigorous tests and industry-leading safety investments align with Wärtsilä’s ongoing effort to not only meet, but exceed, evolving safety and regulatory standards. The company partners with its customers to offer integrated support across its products and lifecycles to ensure full compliance across global markets.
