JTM Energy
For over 30 years, JTM Energy has been a leading pioneer in battery powered technology, powering progress with dependable high-performance products.
Today we manufacture a range of battery energy storage systems — from compact single-phase units suitable for residential or light commercial applications, to industrial and construction-grade energy storage solutions; Designed to cut emissions, lower costs, and keep operations running.
Where We Power
Qualified & Certified Clean Energy Systems
Construction Sites
Construction Sites
Keep cranes, compounds, and tools running without noisy, fuel-hungry generators. Slash diesel consumption by reducing generator use by up to 85%.
Renewables Integration
Renewables Integration
Turn intermittent wind and solar into round-the-clock energy. Our storage captures every kilowatt, stabilises output, and makes renewables behave like baseload power.
Events & Temporary Power
Events & Temporary Power
From festivals to film sets, our mobile units deliver clean, quiet electricity where and when you need it — no fumes, no engine roar, just dependable power.
Commercial & Industrial Facilities
Commercial & Industrial Facilities
Reduce peak demand charges, safeguard operations against blackouts, and power critical loads with flexible, scalable battery storage tailored to your site.
EV Support
EV Support
Deploy fast-charging capacity without costly grid upgrades. Our systems act as on-site buffers, ensuring your EV charging hubs stay powered, even at peak demand.
Residential
Residential
Give homeowners energy independence with compact battery systems that store solar power, lower bills, and provide backup during outages.

Projects
Clancy Construction Scale Away!
Clancy Construction previously relied on three 200 kVA generators running 11 hours a day to power two tower cranes and a site compound. This approach was costly, noisy, and fuel-intensive.
Following the installation of our custom-built 160 kVA / 240 kWh containerised battery energy storage system, the site is now powered entirely from the container, 24 hours a day. Generator usage has been reduced to just one unit running for as little as two hours per day—a dramatic cut in fuel consumption, noise, and emissions.

Elliot Construction Scale Away!
Elliott Construction deployed a 90.120 unit to power both a crane and a small site compound for their residential development on Hill Street, Dublin. With the site located in an area surrounded on all sides by homes, maintaining quiet, low-impact operation was a key priority.
The system met the challenge: the project is power 24 hours a day with only two hours of generator use around lunchtime, ensuring minimal disruption to neighbours while keeping the site fully powered.
Resolute.
We delivered a custom-built 90KVA/180KWh battery energy storage system for a Resolute Engineering project at a sports complex in Co. Kildare, Ireland. The system integrates seamlessly with the client’s existing solar PV installation, along with a newly installed PV carport array.
This setup allows the facility to operate largely off-grid, charging the battery through solar generation and supplementing with low-cost nighttime electricity. The result is a highly efficient, sustainable, and cost-effective energy solution that significantly reduces reliance on the grid.
