In 2019 ESI worked as EPC for the revamping of a photovoltaic power plant of 24,4 MWp in the area of Viterbo, in the so - called district Sugarella.

The plant, already existing and in function for 7 years, registered serious problems both on the functioning and the sustainability.
ESI has carried out the revamping of the PV modules, tracker and the low voltage distribution line.

The renovated power plant is characterized by an increase of the production thanks to the installation of a totally electrical mono-axial tracker, with the elimination of hydraulic oil.
