The cost of electricity in Italy has gradually increased over the past five years to an average price of €0.20 / kWh, a significant cost for both industry and trade.

This increase is mainly due to factors not directly related to the actual price of electricity production (such as network service, taxes and general costs) and it is highly unlikely that in the medium to long term we will see a reversal of the trend as growing independent consumption will lead to a further influence of such factors.

A photovoltaic system designed to meet the customer’s consumption profile allows a reduction in the average cost of electricity to €0.14 / kWh in areas of central and southern Italy and €0.15 / kWh in areas of northern Italy, fixed for the next 25 years.

Enerqos boasts a constructive experience of over 130 MW of photovoltaic, for most of which today it carries out maintenance activities (ordinary and extraordinary) and performance monitoring.

Enerqos’ proposal

  • Design and implementation of a photovoltaic system optimized to meet the electricity consumption profile of the customer
  • Support in obtaining bank financing
  • Monitoring and maintenance service for the photovoltaic system

Benefits for the customer

  • Immediate reduction in energy costs and increase in company competitiveness
  • Protection against future increases in the cost of electricity
  • Medium to long term support from trusted and highly qualified partner
  • Improvement in the customer’s ‘green’ image

Priority areas

  • Full week daytime industrial production
  • Commercial businesses (department stores, outlets, car showrooms)
  • Office buildings
  • Hospitals, care homes

*PVGIS data (http://re.jrc.ec.europa.eu/pvgis/) considering:

  • UAn optimal inclination
  • Azimuth of 0°
  • System efficiency of 82%

** the regime of “net metering”, regulated by Resolution ARG / elt 74/08, is a specific way to improve electricity consumption which allows the possessor of a photovoltaic system to achieve consumption by putting self-produced electricity into the grid which is not directly self-consumed but is subsequently withdrawn at a different time from that in which the production took place.
