Coulomb Solutions, Inc. Launches ReadyGrid, a Dedicated Mobile Energy Storage Company
The New company brings CSI's commercial vehicle electrification expertise to rapidly deployable power solutions ranging from 233 kWh to 5 MWh
LIVERMORE, Calif., Oct. 27, 2026 /PRNewswire/ -- Coulomb Solutions, Inc. (CSI) today announced the launch of ReadyGrid, a dedicated mobile energy storage company created to deliver best-in-class products and services addressing some of its customers' most demanding power challenges.
Effective November 1st, CSI will transition all its Mobile Battery Energy Storage System (BESS) activities to ReadyGrid, including engineering, product development, purchasing, manufacturing, sales, distribution, service and warranty. The creation of CSI's new dedicated organization brings these capabilities together under one brand with a singular focus: developing, delivering and supporting rapidly deployable power solutions that solve real-world energy and infrastructure challenges.
CSI has established itself as a leading provider of electrification components for the North American commercial vehicle market, providing advanced high-voltage battery systems, low-voltage batteries and electrification components through its strategic partnership with CATL, the world's largest battery manufacturer. More recently, over the past two years, CSI has applied that expertise to a new challenge: delivering substantial electrical capacity where permanent grid infrastructure is unavailable, constrained, delayed or uneconomical.
ReadyGrid was formed specifically to take that capability to the next level. The company has developed a portfolio of rugged, rapidly deployable energy storage systems ranging from approximately 233 kWh to 5 MWh, addressing applications including high-power commercial EV charging, demand response, grid resiliency, data centers and other high-load facilities, construction and remote operations, peak shaving, entertainment and sporting events, and emergency or temporary power.
Creating ReadyGrid gives this business the dedicated people, resources and focus to solve our customers' toughest power challenges and scale rapidly," said David Mazaika, CEO of Coulomb Solutions, Inc. "We see an enormous and growing need for electrical power that can be deployed wherever and whenever it is needed. We have developed outstanding products, built expertise and, through our partnership with CATL, have access to world-class battery technology and supply."
The launch comes as the global market for mobile energy storage is projected to expand significantly. According to research from Astute Analytica reported by Yahoo Finance in January 2026, the global Mobile Energy Storage System market is projected to grow from approximately $7.57 billion in 2025 to $34.03 billion by 2035, representing a 16.22% compound annual growth rate from 2026 through 2035. Systems below 3 MWh represent the largest capacity segment at more than 39.31% of the global market, while the United States accounts for more than 75% of the North American market.
ReadyGrid, is a wholly owned subsidiary of CSI. ReadyGrid combines advanced mobile battery energy storage technology with intelligent software, telematics, and real-time data monitoring. The .ai domain reflects our ongoing commitment to smarter, data-driven energy solutions, supporting applications ranging from mobile power and EV charging to the rapidly growing demands of AI data centers. ReadyGrid's initial product portfolio will span approximately 233 kWh to 5 MWh, led by its next-generation 2.3 MWh Mobile BESS. The flagship product combines approximately 2.3 MWh of energy storage with an integrated 1 MW power conversion system, providing both 480VAC power and up to 1 MW bidirectional Megawatt Charging System (MCS) capability for high-power commercial vehicle and equipment charging. Engineered for frequent transport and rapid deployment, the 2.3 MWh system has been evaluated for compliance with applicable UL 9540 requirements and incorporates commercial vehicle-grade LFP battery technology from CATL. The result is a rugged, high-capacity power platform that can be deployed quickly wherever sufficient grid infrastructure is unavailable, constrained or cannot be delivered fast enough.
Unlike conventional stationary BESS installations, all ReadyGrid systems are engineered specifically for frequent transport and repeated deployment. They incorporate commercial vehicle-grade, long-life LFP battery technology, integrated thermal management and ruggedized system architecture designed for demanding mobile applications.
ReadyGrid will be led by Greg Laudermilch, Vice President of Sales and Marketing, who joined the organization specifically to build and grow the Mobile BESS business after 25 years leading Caterpillar's global heavy equipment and electrification efforts. Laudermilch will lead the company's commercial strategy and market development as ReadyGrid expands across fleet, industrial, utility, infrastructure and temporary-power applications.
Greg Laudermilch, VP of Sales says, "With ReadyGrid's portfolio of mobile BESS, energy is no longer a constraint. Customers now have the full autonomy to manage their energy and power needs on their terms.
