What we do

With a team made of qualified specialists in different areas, Exalto delivers studies and researches in the energy field, from land planning to experimenting innovative solutions.  

In case of existing factories, Exalto analyzes production processes through energy audits in order to highlight ways to reduce energy consumptions and introduce innovative technologies.

Exalto can act as an Esco in finding ways to minimize Energy consumptions, promote energy savings measures and trade White Certificates.

Exalto supports AzzeroCO2 (LINK) in designing integrated Platforms of the National RECALL program for the management and treatment of vegetable byproducts.

Exalto is also working on studies and researches in the energy field, from land management to innovative technologies experimentation like tank-integrated solar thermal panels and plasma torches.

Exalto can help developers design new buildings that minimize energy consumptions toward a zero emission goal.

For developers of new industrial areas we can provide design of the best solar technologies and of district heating and cooling combined with cogeneration plants or very high efficiency technologies.

Exalto provides energy audits with different levels of accuracy and can also grant energy certification of buildings.

Exalto designs and installs PV systems on rooftops, also by replacing asbestos covers.

We are also interested in renting the right of surface to use the rooftops of buildings with solar projects by paying a yearly fee for 20 years or also a one time full payment covering all 20 years. 

Exalto works with AzzeroCO2 for the “Provincia eternit free” program, that aims to substitute asbestos covers with BIPV plants.

Exalto, as an EPC, installs biomass cogeneration systems and is also working on the vegetable oil supply chain through the Eubioil consortium. 

Biofuel-run engines – endothermic cogeneration engines running with vegetable oil (i.e. rapeseed, palm or sunflower oil) or other liquid biomass. Our main proposal focuses on 1 MWe size with nautical-derived engines, especially suitable to work with vegetable oil. Usually the efficiency of these engines is about 83% (38% electricity and 45% thermal energy) with 17% of losses.

Electricity is fed into the network, while heat can be sold to nearby users. The motors used are common Diesel engines, adapted to work with vegetable oil.

Exalto grants to those customers interested to buy the complete pack (plant, oil and O&M) the possibility to get fuel at a fixed price

Solid biomass-run engines – in this case the typical Rankine cycle is used in its simple form (steam, or bio-fluid).

Solid biomass, both woodchips and other pre-treated raw materials, are burnt in a heater and the steam produced starts a turbine combined with an alternator. Heat is recovered in many ways: exhausted smoke, condensation, and spills.

The best size is always 1 MWe, granted by the combination of a steam generator with a condensation turbine when the priority is for the electricity production, with a counter-pression turbine when the priority is the production of thermal energy. Some balancing is possible with spills. Exalto also proposes 3.5 and 10 MWe plants.

For smaller sizes (200 kWe – 1 MWe) it is possible to combine a regular oil heater and an ORC (Organic Rankine Cycle).

Eubioil consortium – it is a consortium founded by Exalto and Seada – dedicated to the activities of vegetable oil production, self-production, purchase, supply, distribution, sale and division through the consortium associates.

The consortium associates are finishing the installation of 20 MW of several small size generation plants with an yearly expected consumption of 40.000 tons starting from June 2011.

The goal of the consortium is the creation of a Purchasing Group for the supply of pure vegetable oil for electricity generation, granted by the tracing system valid for the Italian Authorities. 

Futhermore, the consortium allows the creation of companies for rapeseed cultivation in Romania. In summer 2011 10000 hectares will be cultivated.

The installation of renewable Energy plants on land needs a special care in order to grant a correct landscape integration and to avoid negative interactions with agriculture.

Exalto’s approach aims to integrate the installation of PV plants with sustainable agriculture.

Concentration PV for agriculture renaissance in Southern Italy

In many areas of Southern Italy that are abandoned or with high risk of abandonment PV may represent an interesting way to restart cultivation. We aim to build PV trackers spaced enough to allow agriculture production. In this way it’s possible to increase the added value of the cultivations, increase jobs and reduce land abandonment, all thanks to solar revenues. In fact, CPV revenues allow to pay for larger than usual fields and to pay for the extra agriculture costs.

Exalto is working the the French-German company Soitec Solar in order to develop a series of plants on Apulia and Sicily.

The program “High efficient concentrators tracking solar systems in Sicily and Apulia to improve agriculture production” has been endorsed by the European Commission's Sustainable Energy Europe Campaign as an Official Partner.

Cogeneration CPV plants

Exalto proposes innovative solar solutions with combined heat&power generation useful for touristic or industrial sites which need heating or cooling in Southern Italy.

Exalto develops small wind turbine projects (from 20 to 200 kW), solar thermal systems, biomass heaters, geothermal heating sysyems as well as LEDs.
