Improving site energy efficiency: predicting power needs

Home Promo Graphic


For rental operators and end users alike, Hybrid Power Systems are now a well established tool to save fuel, and reduce CO2, localised pollution and noise.  However, power supply is only part of the equation on site.

The key to maximising the benefit of using Firefly’s Cygnus® Hybrid Power System is improving energy efficiency on site. This is not always easy to do when lights and heaters are left on overnight, windows and doors are propped open – whilst the heating is running.

Switching to energy efficient consumers such as LED lights; retro-fitting timers, PIRs and thermostats; improving cabin insulation and encouraging staff to be more aware can help. But it’s not always possible to do this, and even if it is – there is always more to be done.

Firefly’s Timed Distribution Unit provides the site mangers with the confidence that energy efficiency and CO2 reduction objectives can be achieved. The TDU takes the guess work out of saving energy and helps service providers and users predict power requirements more accurately. In a typical site set up, that uses a diesel generator and Cygnus® Hybrid Power System, the TDU increases the overall savings on site by eliminating the supply of energy to unused consumers. Overnight loads are kept to an absolute minimum by using the user defined timer function in the TDU. Each of the six 32A single phase outputs can be individually controlled to create a finely tuned power distribution set up.

In the event that work patterns change, the TDU is easily re-programmed via an in-built TFT touch screen. Alternatively the manual over-ride function means that temporary extensions to work hours can be met, without requiring any re-programming. Critically the time limit on the manual over-ride ensures that power supply is automatically controlled, ensuring energy efficiencies are still achieved.

TDU is the smart way to improve energy savings and a must have addition to temporary power installations on site.
