As the UK and Ireland accelerate towards lower-emission operations and more sustainable construction practices, battery energy storage is rapidly becoming one of the key technologies supporting the transition. One Irish company attracting growing attention across the UK market is JTM Energy, a Wicklow-based manufacturer with more than 30 years’ experience in advanced battery solutions.

Originally recognised for supplying high-output jump starters for heavy-duty vehicles, buses and rail applications, alongside EV roadside rescue systems and specialist battery products, JTM Energy is now rapidly expanding its Battery Energy Storage System (BESS) offering for both off-grid and on-grid applications.

All systems are designed, assembled, and tested in-house at the company’s facility in Rathnew, County Wicklow, giving customers confidence in quality, technical support, and long-term reliability.

For construction companies, transport operators, logistics firms, and infrastructure providers facing increasing pressure to reduce emissions and fuel consumption, the benefits are immediate and measurable.

When integrated with diesel generators, JTM Energy’s BESS solutions can reduce generator running times by up to 80%, significantly lowering fuel costs, maintenance requirements, carbon emissions, and site noise. On construction sites — where generators often operate continuously at inefficient loads — the savings can be substantial. With rising HVO fuel costs, stricter sustainability targets, and growing pressure to reduce noise pollution, battery storage is quickly becoming an essential part of modern site operations.

JTM recently invited a prospective client to a customer site in Dublin where one of its systems was supplying silent power to a large construction compound. During the visit, the customer explained that fuel consumption had been reduced by approximately 1,000 litres per week. The prospective client immediately recognised the scale of the savings, estimating a reduction of more than €1,500 per week in HVO fuel costs alone.

Examples like this are increasingly raising questions about whether UK public sector and infrastructure projects should begin mandating the use of battery energy storage systems on sites wherever practical — reducing emissions while also delivering major operational savings and quieter working environments.

Alongside its hardware offering, JTM Energy has developed proprietary energy management software that provides real-time monitoring and analytics through on-unit displays and remote dashboards. Combined with 24/7 monitoring support and flexible Energy Storage as a Service (ESaaS) options, the company is now targeting significant growth across the UK and European markets.

For businesses seeking practical, scalable energy storage solutions, JTM Energy is helping reshape the future of sustainable transport, construction, and infrastructure.
