Micro inline hydro turbines for aqueducts

Among the various cases of application of off-grid electrical production systems in which FGS Energie Alternative is specialized, there are particular situations when it's extremely convenient or even obligatory for reasons of distance to keep the equipment isolated from the network.

In the aqueducts in mountain areas generally the sources or the first water treatment plants are located on the territory where the availability of water allows, with the consequence that these structures are found in narrow gorges or ravines, small valleys, very frequently unreachable even to wheeled vehicles, where a maintenance worker can only arrive on foot.

In these cases the electric current of the network is obviously absent for various reasons, first of all the fact that generally, and at least in the past, no particular electrical equipment was needed at the source.

In recent years, however, for various regulations and control needs, even on these sites it's necessary to do a series of operations that require electricity, such as water treatment, or simply

transmission of monitoring data such as levels, chemical data, etc.

The simplest solution often used is to apply a small photovoltaic system with an accumulation system, which however often proves to be unreliable, above all because in these sites we have problems of vegetation and very narrow horizon, if we are inside valleys. As a consequence, the accumulation batteries suffer, due to the irregular charge, involving frequent maintenance and instability of the system.

In these cases, FGS Energie Alternative proposes a range of micro-turbines suitable for the production of electricity, directly or with accumulation systems, necessary for these users.

Let's see for example an application of a micro turbine in line with the aqueduct.

FGS wall mounted systems in Mini-Grids

The Global Scenario:

Until a few years ago, mini-grids were considered as a solution to take advantage of the energy produced from renewable sources in small communities or in small groups of users.

This concept has been increasingly extended over the years to reach far more important applications in terms of the amount of energy used and thus satisfying requests from small and medium-sized companies.

The IRENA (International Renewable Energy Agency) has estimated that about 1 billion people in the world do not have access to the electricity grid and yet another billion have access that is not reliable and durable for the users.

In order to obtain universal access to electricity by 2030, IRENA has always estimated that investments in this regard are now about half of what would be needed and that 60% of the installed systems, to achieve this goal, must be Off -Grid (ie not connected to the national electricity grid).

In a recent report ("International Outlook Renewable Mini-Grid") the agency also states:

"Increasingly, technological innovations for hardware and software find their way to commercialization by allowing large-scale distribution of renewable mini-grids. We are seeing improvements in production technology, but the real changes we have to expect are those in the areas of communication, control, and energy storage technologies. "


But what does "Mini-Grid" mean properly?


A Mini-Grid (or mini-network) involves the coexistence of multiple users connected to each other and to one or more sources of generation (which can exploit both renewable and non-renewable sources such as diesel generators).

Here's how we build your FGS Storage systems. Today Leaving for Tanzania, Trento, Campania ...

At FGS Alternative Energies we are keen to put our name on the work that will become your energy system.

This is because we know that every customer has his own personal challenges, and FGS Energie Alternative likes to be next to the customer to achieve the desired energy goals.

Customization: is what FGS Energie Alternative srl allows to do with your system.

This is also thanks to their modularity, which makes it possible to expand them, both in the design phase or later.

A forefront Micro Hydroelectric plant

The small system for capturing water that has been realized.


One of our company philosophies is to be always on the lookout for technically advanced solutions, thanks to our study and experimentation.

We have created a micro hydroelectric plant, off grid, with particularly advanced technical solutions in every component of the system.

The construction site was a small farm adjacent to a valley called precisely "valley of the mills", where historically there were some milling buildings in the waterfall, which exploited a small mountain stream.

The request in this case was to be able to generate electricity using the water head, in a plant however disconnected from the grid, without then placing and selling energy, practically in complete self-consumption.

After an inspection we noticed:

- A water head, thanks to the presence of two waterfalls, between the location of the intake and the position of the turbine, of 56 meters.

- A variable water flow rate during the year, unfortunately we could use only about 2-3 liters per second with our concession.

That's Incredible ... our renewable energy is indispensable even in the desert for the oil industry!

That's Incredible ... our renewable energy is indispensable even in the desert for the oil industry!

FGS Energie Alternative deals with the design and supply of island systems, providing standard systems or systems  with specific customer characteristics. In this case, a major customer in the Oil & Gas sector had to make autonomous oil-pumping micro-stations with cathodic protection located in isolated areas in the United Arab Emirates.
We have supplied systems that we have designed and tested according to the restrictive requests of the customer who wanted to test the systems in the oven at high temperatures to simulate the most arduous working conditions.
Also this time we pushed our services a little further and the customer found in us the flexibility and the competence to reach the perfect solution for his problem!
