5 Things you need to know before selecting your temporary power supply

Regardless of why you need a temporary power supply (emergency power, maintenance projects, commisioning projects, peakshaving, greenfield development off grid...), every project has unique specifications.  These are crucial to select the best temporary power solution for you.

It is crucial to know how much your power demand fluctuates over time.  This will largely be determined by the reason you need the temporary power supply.

• When you need back-up power for a production facility; the power flucuations will most likely be caused by either production shifts or the specific processes in your operations.  These can vary greatly.
• On the other hand, commisioning projects usually require high varations in power.

Diesel driven power modules are an efficient power source when running at full load.  When your power demand is stable, select the power module that is the best fit for your maximum power requirement.

On the other hand, flucuations will cause a power module to run at partial load; greatly decreasing efficiency of the temporary power solution.  When your power demand varies over time; make sure to check alternative set-ups, such as a hybrid power plant.

When your site is connected to the grid; you might only need power at specific times to balance a temporary power shortage or expected power downtime.  Contact a specialist to optimize your available grid and a temporary independent power supply for the most efficient solution.

Any power source can be potentially hazardous.  When installing a temporary power supply, make sure your supplier is well equipped and trained to handle this in a proper way - so you can enjoy a safe supply of power.  Look for ISO certification for official validation.

Consider the location where the temporary power plant needs to be installed. 

• What is the maximum footprint for the temporary installation?  You supplier should be able to share a detailed plan.  Keep in mind installation and decommissioning also require space.   
• Access on the site: your operation might be critically protected, requiring high security clearance to access the site.  Some installations require regular maintenance intervals -  meaning more frequent site visits are required.  When access is an issue; ask your supplier for the most optimal solution.
• Is the site easy to reach?  Whether remote, in rought terrain or even offshore; make sure you select a supplier that can easy and quickly reach your operation.
• Impact on site: make sure to specify any requirement whether it comes to noise, heat, ... or any other impact the temporary installation might have.

Stage V, T4F, zero emission zones, noise restrictions in urban areas... every site has to take into account the local legislations during the project preparation stage.  CO2 emission might be the most obvious restriction; but there are many more eg:

• Local electric standards on equipment and installations (cablings, earthing, etc,...)
  
• Safety
• CO2 Emissions
• Noise levels
• Ground pollution
• ...
