France – current electrical power: variable 5kW to 10kW for construction sites.
As part of a cost-cutting initiative, a large French civil engineering firm wishes to power the living accommodation at its sites using electricity while reducing its environmental impact.
. By selecting GELEC Energy, the firm has been able to meet its 2 objectives:
1- Economic: very significant cost reductions (fuel consumption reduced by 65%). Cogeneration enables heat produced by the generating set’s engine to be recovered at no cost in order to supply the central heating system and produce hot water for personal hygiene.
2- Environmental: lower impact on the environment thanks to a hybrid solution combining photovoltaic power, energy storage, a generating set running on crude vegetable oil and CHP.
Photovoltaic plant producing power of 5 kWc extendable to 10 kWc,
+ 20 kVA PPO technology genset,
+ diesel fuel and PPO tanks for the genset,
+ 46 kWh OPzV power bloc,
+ 24 kVA bidirectional inverters,
+ CHP system with 2 X 1000-litre tanks,
+ All-in-one 20ft ISO container.
The photovoltaic plant is installed on the ground. The generating set, energy storage and power electrics are containerised.
The optimised sizing of the installation gives a cost of €0.30 per kWh produced, cogeneration included, against €0.50 for a generating set alone.

What are the reasons behind the new HPOD model?
“Mobile power is in ever increasing demand but is not really covered by our current range. Popular among artisans, market traders, food trucks and, more generally, for any activity requiring electricity at remote sites. Small petrol-powered generating sets are typically used with very high fuel consumption and very limited life cycle. Our Design & Engineering Department has been actively working on product specifications combining mobility, weight and performance, notably in terms of autonomy.”

What is the HPOD M3 ?
“The HPOD M3 comes in the form of a traditional “flycase” mounted on large castor wheels. Fitted with side handles, the HPOD M3 is easy to handle. Its dimensions of 50x50x50cm form a cube that is easy to store, even in a car boot. It delivers power of 3 kVA with customisable autonomy: it offers 2.5 kWh of storage (or 5 kWh with an additional rack). The two versions are offered with AGM maintenance-free batteries. There is also a lithium version with a 4 kWh battery offering even greater autonomy.”

So lithium is featuring for the very first time?
“Indeed. Lithium is very interesting technology thanks to its high discharge rate and longer useful life than lead-based technology. Finally, its weight is a real bonus in the field of mobile power.”

What are the strong points of the HPOD M3?
“As with all HPODs, it delivers clean and silent electricity. It doesn’t need any fuel or maintenance. It emits no noise or smell, nor does it leak. Fully electric, it can be recharged from the mains, via solar energy or using a generating set. It is fitted with earth leakage protection and integrated sockets. The HPOD is also ideal for town centre locations and protected areas where the use of generating sets is prohibited.”

Is this system more expensive than a portable generating set?
“The initial investment is admittedly higher, but you have to take into account all the costs associated with using a small portable generating set: oil, petrol, maintenance and replacing the genset. The cost of the HPOD M3 is written off very quickly. All the more so as the battery lifespan is around 20 years. Savings will be made in the short term.”

When will the HPOD M3 become available?
“It already is. Orders can be placed now with delivery in 5 weeks.”
