Renewable energy resources

The energy efficiency challenge is increasingly oriented towards a sustainable development. 
ENGIE Italia undertakes to use renewable energy sources, which range from solar, thermal and photovoltaic systems to the use of biomass. 
Sustainable, high energy efficiency solutions also requested by major national companies.

 

SOLAR AND PHOTOVOLTAIC SYSTEMS

The largest energy source.

 

Solar energy systems can produce heat or electricity continuously, eliminating the emission of pollutants into the environment.

These plants are chosen increasingly frequently both by public organizations and by small and large companies, but also by private buildings and residential condominiums.

In fact, solar energy ensures autonomy and considerable savings on production costs.

 

ENGIE Italia offers professional consulting on legislation and the possibility of access to economic incentives, so as to be able to offer the best solution for every customer’s energy requirement.

It analyses the surrounding area and the structure of the buildings, the installation and subsequent control and maintenance of the plants.

 

SOLAR THERMAL ENERGY

 

Converting solar energy to thermal energy without emitting pollutants and without using fossil fuels is possible using a solar thermal energy plant, available in two types:

 “forced circulation” (configuration indicated for the production of large quantities of hot water or heating): there is a hydraulic system regulated by a pump and an automatic temperature control system. The hot water storage tank is larger and positioned in a service area.

“natural circulation” (configuration indicated for the domestic production of hot water or heating): water flows in the pipes without any pumping systems. The storage tank is normally close to the solar panel, so as to guarantee maximum system efficiency.

 

PHOTOVOLTAIC SOLAR ENERGY

 

Converting solar energy into electricity for the home, without using any fuel.

Some specially treated materials have the ability to generate electricity if exposed to luminous radiation. This is due to the “photoelectric effect” exploited by the solar photovoltaic system to produce electricity.

 

Photovoltaic systems consist essentially of:

  • photovoltaic panels: made up of a semiconductor material (in general, mono or poly-crystalline silicon), capable of producing electricity from solar radiation;
  • inverters: to regulate the operation of the photovoltaic panels and convert direct current into alternating current (useful for powering electrical household appliances and feeding into the grid);
  • production meter;
  • local network trading meter: the energy produced by the plant and measured by the trading meter, but not consumed, is sent to the electrical grid to receive further incentives.

 

BIOMASS PLANTS

Energy from nature.

 

Obtaining energy from organic, plant and animal-derived materials is possible. Biomass is used as a fuel, directly for the production of energy o converted into Biogas, which can, in turn, be used as fuel.

Energy in complete harmony with nature, which, unlike oil-derived fuels such as methane and oil, limit waste and the emission of carbon dioxide into the atmosphere.

The most significant examples of cogeneration with woody biomass used by ENGIE Italia include the plants installed in the municipal districts of Rivarolo (TO) and Sedrina (BG).


 

SUCCESS STORY:
San Giovanni Addolorata Hospital

Photovoltaic canopies installed in the new hospital carpark: 792 photovoltaic panels covering a total surface area of 1,306.80 m2. An annual electricity production of 214,204 kWh.

A power corresponding to the energy requirement of the large radiology equipment present at the hospital, such as CAT and magnetic resonance imaging devices and linear accelerators.

The new plant will also provide power for the lifts and some of the internal lighting. An annual CO2 saving of 107,000 Kg, which is equivalent to taking about 100 cars off the road.
