Società Elettrica Ponzese SpA is the company that carries out the production, distribution, measurement and sale of electricity in the Municipality of Ponza. Production is currently entrusted to a temporary power plant in Monte Pagliaro and to an emergency power plant located in Cala dell'Acqua in Le Forna.
The project under implementation is the creation of a definitive power plant which provides for the expansion of the electricity production capacity of the current temporary power plant with use of a share of production from renewable sources (Photovoltaic).
The new power plant, in addition to seeing the production capacity increased to 8,2 MW through diesel generators, provides for a rational use of part of the thermal energy contained in the engine cooling water and combustion gases. This recovery will be achieved by means of a Rankine cycle unit (ORC) combined with one of the new engines of the power plant or alternatively with two of the existing engines; the possibility of heat recovery through a battery of exchangers is also envisaged to make a significant amount of energy available to other public or private entrepreneurial subjects.
In addition, the complex of covering surfaces of the technical areas, combined with a photovoltaic field on the ground outside the power plant area, will allow the construction of a photovoltaic system of approximately 500 kW overall, integrated with an energy storage system.
A significant aspect of the new work is the integration of the electricity distribution network with charging stations for electric cars that can be used both by the fleet consisting of the work vehicles of SEP personnel, and for public use.
