About Us
About JTM Energy
At JTM Energy, we believe the future of power lies in storing it. Based in Rathnew, Co. Wicklow, we design and manufacture advanced battery energy storage systems that give people and businesses the freedom to use clean energy on their own terms.
Our solutions capture renewable power from wind and solar and make it available when it matters most — cutting costs, reducing carbon emissions, and ensuring reliable electricity around the clock.
For off-grid applications that have traditionally relied on diesel generators — such as construction sites — our systems deliver a cleaner, quieter, and far more efficient alternative, reducing generator use by up to 85% and slashing diesel consumption.
Our Story
Customers include Dublin Bus and Iarnród Éireann. The jump starters and a range of accessories are available to buy from jumpstarters.ie.
We Innovate to Differentiate!
JTM made global headlines in 2011 with the world’s first roadside EV rescue pack — delivering emergency top-up power to drivers who run out of charge and used by the AA and ESB eCars. While public charging networks reduced the need for roadside rescue, the technology is gaining renewed interested from construction companies needing on-site EV charging solutions. The mobile EV rescue pack was energy storage on wheels — a breakthrough that paved the way for the advanced battery systems we manufacture today.
Made in Ireland, Built to Last
Every JTM Energy system is built in-house at our Wicklow facility. By keeping design, assembly, and testing under one roof, we ensure the highest standards of quality and safety. Our enclosures are compact but powerful, our monitoring technology is cutting-edge, and our systems are engineered to withstand the demands of real-world use.
