Temporary power solutions using battery energy storage
Temporary power is essential for many industries. Construction sites, infrastructure projects, agricultural operations and outdoor events all require reliable electricity long before permanent grid connections are available. Traditionally, this has meant diesel generators.
Generators are effective, but they come with limitations. Fuel costs, maintenance requirements, emissions and noise can all create operational challenges, particularly on projects that run for months or even years.
Battery Energy Storage Systems (BESS) are increasingly being used to improve how temporary power systems operate. When integrated with generators, grid connections or renewable energy sources, they allow sites to deliver power more efficiently and with greater reliability.

BESS: What is temporary power?
Temporary power refers to electrical systems installed to support operations where permanent infrastructure is not yet available or where grid access is limited.
Common examples include:
- construction and infrastructure projects
- remote agricultural facilities
- temporary industrial operations
- outdoor events and festivals
- emergency or disaster response operations
These environments often require flexible power systems that can adapt as site requirements change.
BESS vs the traditional approach: diesel generators
For decades, diesel generators have been the default temporary power solution.
They are widely used because they are:
- portable
- reliable
- capable of delivering high power output
However, generator-only systems can create operational inefficiencies.
Generators often run continuously even when power demand is low. This can lead to:
- unnecessary fuel consumption
- increased servicing requirements
- higher operating costs
- excess noise during quiet periods
As industries face growing pressure to improve efficiency and reduce emissions, driven by evolving energy policy and decarbonisation targets from organisations such as the UK Department for Energy Security and Net Zero, many organisations are looking for better ways to manage temporary power.
How battery energy storage supports temporary power
Battery Energy Storage Systems allow sites to store electrical energy and release it when required.
Instead of relying entirely on a generator running continuously, a hybrid system can combine several energy sources, including:
- diesel generators
- grid connections
- solar power
- battery storage
In these systems, batteries act as an energy buffer. They supply power during low-demand periods and support generators during high demand.
This approach allows temporary power systems to operate more intelligently.
Key benefits of BESS for temporary power
A good microgrid does not necessarily remove the generator.
In many off-grid and temporary applications, the generator remains essential. The difference is that it becomes one part of a wider energy system rather than the whole solution.
That is an important distinction.
Generators are often at their best when they are properly loaded. The issue is that many sites do not consistently demand that level of power. So the generator can end up running inefficiently for long periods, burning fuel and producing emissions even when the actual load is relatively low.
In a microgrid, the generator can be used more intelligently.
It can start when the battery needs charging. It can support periods of high demand. It can provide backup when required. But it does not have to run constantly just because power is needed somewhere on site.
That is the shift. The question is no longer simply, “What generator do we need?”
It becomes, “How should the generator, battery storage and site loads work together?”
That is where the savings begin.
Temporary power use cases for battery storage
Battery storage is increasingly used across a wide range of temporary power applications.
Construction sites
Construction projects often require power before permanent infrastructure is installed. Hybrid battery systems can support equipment, lighting, site offices and temporary facilities.
Infrastructure and utilities projects
Projects such as roadworks, rail upgrades and utility installations often require temporary energy solutions that can operate reliably for extended periods.
Agriculture and rural operations
Temporary or seasonal agricultural operations may require power for irrigation, processing or refrigeration equipment.
Outdoor events
Events often require silent power during specific periods, particularly overnight in residential areas.
Battery storage can provide energy without running generators continuously.
Hybrid temporary power systems
The most effective temporary power solutions often combine battery storage with existing generation systems.
In a typical hybrid setup:
- The generator charges the battery when required.
- The battery supplies energy to site loads during lower demand periods.
- The generator starts automatically when higher power levels are needed.
This allows the system to deliver reliable power while reducing unnecessary generator operation.
Hybrid systems can also integrate renewable energy sources, creating more flexible and efficient temporary power solutions.
What to consider when deploying BESS for temporary power
Battery storage can provide significant benefits, but successful systems depend on proper design and integration.
Important factors include:
Site load profile
Understanding how energy demand changes throughout the day helps determine the appropriate system size.
Generator compatibility
Battery storage must integrate effectively with existing generators and power distribution systems.
Deployment environment
Temporary sites often operate in harsh conditions, so equipment must be designed for outdoor use and demanding environments.
System monitoring
Remote monitoring and energy management tools allow operators to track performance and optimise system operation.
BESS - A more intelligent approach to temporary power
Temporary power requirements are unlikely to disappear. Construction, infrastructure and agricultural operations will continue to rely on flexible energy systems.
What is changing is how those systems are designed.
Battery Energy Storage Systems allow temporary power setups to operate more efficiently, using generators only when necessary and integrating renewable energy where available.
For many organisations, hybrid power systems are becoming the practical next step in improving reliability, reducing costs and preparing for future energy demands.
