Producers of electricity from systems with a capacity of up to 20 kW and 200 kW, can make use of net metering (Scambio sul posto). This options can be used as an alternative to the feed-in tariff 'Tariffa Omnicomprensiva' and for the sale of electricity on the free market or on the market regulated by "ritiro dedicato".

Net metering does not result in direct payments and is based on the balance of energy fed in and consumed (Art. 1,2 ARG/elt 74/08). This mechanism grants the owners of these systems payments equal to the difference between the value of the electricity fed in (with PV systems the energy fed in during the day) and the value of the electricity consumed in a different period.

If more energy is fed in than is consumed, this positive balance can compensate for a possible negative balance in subsequent years (Art. 5 ARG/elt 74/08). Generators who feed in more electricity than they consume do not receive any payment under the net metering scheme. If they feed in less than they consume, the additional electricity consumed will be invoiced (Art. 5 par. 6 ARG/elt 74/08).
