The current condition of the energy grid is one of the limiting factors of the energy transition. SmartGrid is here to solve that. Founded in 2019 by Kees Koolen, founder and former CEO of Booking.com, SmartGrid is a subsidiary of Koolen Industries.

SmartGrid offers energy storage systems for industrial and mobile applications, based on the principles of Lithium Iron Phosphate (LiFePO4) batteries. Sizes can vary up to several MW per hour, supplied both as standard container solutions and as customer-specific solutions. All solutions are engineered and built in The Netherlands.

SmartGrid’s design makes it possible to make an autonomous link with clean energy production and existing electricity networks in a simple way, in order to supply energy on AC and DC in the various application areas via (temporary) storage. Through our in-house developed software and thorough system integration set-up, our customers can use the energy systems for, among other things, energy trading, peak shaving, load balancing, DC and AC micro grid, and back-up power.
