Do you trust mobile battery storage systems to provide reliable power when the electrical grid fails?
Coulomb Solutions, Inc. has officially launched ReadyGrid, a wholly owned subsidiary designed to manage its mobile battery energy storage system portfolio. This strategic move aims to address power challenges in locations where permanent grid infrastructure remains unavailable.
Why it matters
The transition allows Coulomb Solutions to sharpen its focus on mobile power delivery by separating it from its broader commercial operations. ReadyGrid will specifically target regions facing power constraints that cannot be serviced by existing utility infrastructure.
ReadyGrid develops mobile systems with capacities ranging from 233 kWh to 5 MWh. The flagship unit features 2.3 MWh of storage paired with a 1 MW power conversion system utilizing CATL LFP battery technology.

Roadmap
The formation of ReadyGrid aligns with a broader industry trajectory toward portable power infrastructure as the global mobile energy storage market prepares for 16.22% annual growth through 2035. This move positions the firm to compete as a specialized provider within a sector increasingly vital for grid-constrained environments.
Customers requiring reliable power in areas lacking grid access can expect more specialized, ruggedized mobile storage units from the new subsidiary. Businesses operating in logistics or remote construction will gain access to improved fleet-grade power conversion and telematics.
The takeaway
The move to separate mobile energy storage into a standalone business reflects the growing necessity of flexible power as grid limitations become more prevalent. Companies should prioritize evaluating portable storage capabilities to mitigate potential operational downtime caused by energy constraints.
