7 Feed-in Tariff
7.1 Feed-in Tariff system and incentive tariffs
Further to the Ministerial Decree DM dated 19/02/2007,
who erects a PV installation connected to the network
and without energy storage systems can obtain “incentive
tariffs”, defined according to the peak power of the
installation and to the type of architectural integration
(Table 7.1).
The Feed-in Tariff consists in the remuneration for the
produced energy and not in the incentive of the capital
necessary to the erection of the PV plant (Initial Capital
Cost).
The tariffs, which are paid out unchanged for a period
of over 20 years 1 , are applied to the whole energy produced
by the plant, independently of the use that the
user is going to make of such production: sale or selfconsumption.
With subsequent decrees (starting from
2009) the Ministries of Economic Development and of
the Environment and the Safeguard of the Territory and
of the Sea shall update the incentive tariffs for installations
erected after 2010.

The maximum power for which incentives can be provided
is 1200 MW with a “moratorium period” of 14 months (24
months for public bodies) as from the date of achievement
of the power limit for which incentives can be obtained.
For the PV installations which will be put into service after
such “moratorium period” however, incentive tariffs can
be provided, but these tariffs are not accumulative with
green certificates and with white certificates (Energy Efficiency
Credits) and shall not be granted for installations
erected for law obligations (311/2006) and put into service
after 31st December 2010.
1 The financial cover for incentive tariffs is guaranteed by the compulsory drawing in
support of the renewable sources present since 1991 in all the electricity bills of all the
energy distribution authorities.
The “basic” incentive tariff can be increased by 5% in
particular non-cumulative cases:
• for installations with peak power higher than 3kW non
integrated, whose owner self-consumes at least 70%
of the produced energy;
• for installations whose owner is either a public/accredited
school or a public structure;
• for installations integrated in buildings, houses, building
structures for agricultural uses in replacement of
Ethernet covering or including asbestos;
• for installations whose public subjects are local bodies with
resident population not exceeding 5000 inhabitants.
The PV installations, for which local bodies are responsible,
can be included in the typology of integrated
installations, not depending on the real architectural
configurations of the plant.
In addition to the incentive, the subject responsible for
the plant can count on a further economical advantage
deriving from:
• power delivery to the grid;
• own self-consumption (partial or total cover);
• Net Metering with the grid (for installations with power
up to 200kW).
With the financial act of 2008, as from January 1st, 2009
for the granting of the building permission for new buildings,
the erection of plants for the production of electrical
energy from renewable sources must be provided, so that
a power production not lower than 1kW for each house
unit shall be guaranteed, technical feasibility permitting.
As regards industrial buildings, with size not lower than
100 m 2 , the minimum power production is 5 kW.
Besides, the net metering system is extended to all the
plants supplied by renewable sources with annual average
power not exceeding 200 kW.
