We have the know-how to combine many different technologies in challenging applications.
We can develop specific solutions for every particular need, thanks to our ten years’ experience in different sectors such as photovoltaic systems, wind power plants, mini-grid systems and storage systems.
The design choices can have different combinations.
The integration phase of the various components chosen, such as inverters and batteries, is of fundamental importance. This phase requires a careful evaluation of possible technical solutions on the market that may be compatible with each other.
ESI has developed solid relationships with the suppliers of the various technologies, which allow us to offer the customer the most economically advantageous solution not only from a technological but also a constructive point of view.
- Extreme flexibility both as regards the energy source and the storage system
- Specific solutions for every particular need
- Important track record on Off-Grid and Mini-Grid systems, which allows participation in the most important international tenders
- Flexible solutions for each specific need = high competence in niche markets
Mini-grid, Off-Grid, Hybrid
Whether it’s a village, a hospital, a school or a company, we can find the best technical solution to light up your community.
As System Integrator, we have acquired an important international track record on mini-grid, off-grid and hybrid systems, which allows us to participate in the most important international tenders. This plant technology, typically composed of a photovoltaic field, a storage system and a diesel unit, is applied in remote areas where there is no power grid or, if available, of poor reliability.
In mini-grid systems, the photovoltaic plant feeds during the day both the village and the batteries, which then provide the necessary energy for the night.
We also design off-grid solutions where there is a need for primary goods, such as drinking water, in absence of a power grid.
Hybrid systems differ in the presence of the grid. The system is designed and built meeting the needs of the site.
In the last 5 years, we realized 6 mini-grids in developing countries and other 2 have been recently awarded in DRC and Burundi.
We have developed solutions using the most interesting storage technologies available on the market, from lithium ions to vanadium flow batteries, exploring the capabilities of each technology.
As the power from renewable sources in energy production rises, storage for frequency regulation and load management on medium and high voltage lines becomes increasingly important.
The main world utilities that manage the electricity grids in different countries have started a program of experimentation across the whole territory in order to optimize the peaks of the grid.
For renewable energy plants, in particular photovoltaic and wind plants, large storage systems are essential for the management of direct sales of energy on the market.
As System Integrator, we make different plants talk to each other.
The aim is the creation of a functional structure that exploits the potential of power plants, creating additional functionalities for the entire system.
