Why Pramac Battery Banks Are the Future of Temporary Power in Ireland
With fuel prices continuing to rise across Ireland, many businesses are looking for smarter and more cost-effective ways to power construction sites, events, and remote projects. Traditionally, diesel generators have been the go-to solution for temporary power — but modern battery technology is changing the industry.
Battery energy storage systems such as those developed by Pramac are quickly becoming a powerful alternative to traditional generators, helping companies significantly reduce fuel costs, noise, and emissions while maintaining reliable power on site.
At MW Hire Group, we are seeing a growing demand for battery power solutions like the Pramac LX series battery banks, particularly for construction projects, outdoor events, and off-grid operations.
What Is a Pramac Battery Bank?
A Pramac battery bank is a mobile Battery Energy Storage System (BESS) designed to store energy and deliver reliable power when and where it is needed. These systems can operate in three main ways:
- Standalone power supply
- Hybrid operation with a diesel generator
- Integration with renewable energy such as solar
The stored energy can be distributed whenever power is required, making it an efficient solution for temporary power needs.
For example, systems like the Pramac LX 45/80 LFP provide approximately 45 kVA of continuous output with up to 75 kW peak power, making them suitable for demanding applications including construction equipment, site cabins, lighting, and events.
The Rising Cost of Fuel in Ireland
Fuel prices have become a significant operational expense for businesses relying on diesel generators.
A typical diesel generator can consume 10–20 litres of diesel per hour, depending on the load and generator size. On projects that run generators for long hours — such as construction sites, festivals, or remote infrastructure works — fuel costs can quickly escalate.
Battery storage solutions provide a way to dramatically reduce generator run time and fuel usage.
How Battery Banks Reduce Fuel Consumption
Battery banks work by storing power and supplying it during periods of low demand, meaning the diesel generator does not need to run continuously.
In hybrid setups, the system automatically manages power demand:
- When demand is low → the battery supplies the power
- When the battery runs low → the generator starts to recharge it
This significantly reduces generator operating hours.
Hybrid battery systems can reduce fuel consumption by around 50% while also cutting CO₂ emissions during operation.
Example Fuel Cost Savings
To understand the potential savings, consider a typical scenario:
Traditional Diesel Generator
- Generator consumption: ~15 litres/hour
- Diesel cost: ~€1.80 per litre (example average)
- 12 hours of operation per day
Daily fuel usage:
15 litres × 12 hours = 180 litres
Daily fuel cost:
180 litres × €1.80 = €324 per day
Monthly cost (20 working days):
€6,480 per month
Hybrid Battery + Generator System
With a battery bank managing the load, generator runtime may be reduced by approximately 50%.
New fuel usage:
90 litres per day
New daily cost:
€162 per day
Monthly cost:
€3,240 per month
Potential savings:
Over €3,000 per month in fuel alone
This does not even include additional savings from reduced maintenance, servicing, and generator wear.
Additional Benefits of Pramac Battery Banks
1. Silent Operation
Battery banks operate almost silently, making them ideal for:
- Events and festivals
- Film and TV production
- Urban construction projects
- Night operations
This eliminates the noise issues associated with diesel generators.
2. Reduced Emissions
Battery power produces zero emissions during operation, helping companies reduce their environmental impact and meet sustainability targets.
3. Lower Maintenance Costs
Because generators run far less frequently in hybrid setups:
- Oil changes are reduced
- Engine wear is minimised
- Service intervals are extended
This significantly lowers long-term operating costs.
4. Reliable Power for Multiple Applications
Battery energy storage systems are ideal for:
- Construction sites
- Outdoor events and festivals
- Film and TV production
- Remote infrastructure projects
- Emergency backup power
- Off-grid applications
Their flexibility allows them to provide clean, reliable power anywhere.
The Future of Temporary Power
The power generation industry is rapidly moving toward hybrid and battery solutions. Businesses are realising that relying solely on diesel generators is becoming both expensive and environmentally challenging.
Battery energy storage systems provide a practical way to:
- Reduce fuel costs
- Lower emissions
- Improve efficiency
- Deliver reliable power
For many applications, battery banks are no longer just an alternative — they are becoming the preferred solution.
