It achieves its objective, the Ministerial Decree of 5 July "Incentives for energy from photovoltaic sources": one year after its enactment, the data show the reduction of the costs of the incentive system and the increase in the contribution of small plants to the total energy produced.
In response to the need to cut the famous pension positions, the average consideration recognized in 2012 for plants that entered into operation under the fifth Energy Account falls to 0.15 euros. Those who have been most damaged and managed to re-enter the Fourth Account, have instead been granted an average incentive almost double (0.27 euros). The great pioneers of the First Energy Account, on the other hand, received more than three times as much (0.51 euros), for each kWh produced.
But the profile of the average investment also changes; of all plants operating under the Fifth Energy Account, as many as 97.6% have a power of less than 20 kW. They covered 29.1% of the energy produced in 2012 by plants incentivized with the Fifth Energy Account. For plants authorized by previous incentive plans, the percentages of electricity generation by lower power plants are much lower: 12.7% for the Fourth Account, 13.7% for the Third, 18.0% for the First.
As you imagined, the stricter rules and lower remuneration discouraged the most: the additional power installed in 2012 stops at 3,437 MW, when a year earlier it was almost three times. Of these only 448 MW come from plants authorized under the Fifth Energy Account.
However slowed down, electricity production from a photovoltaic source still reaches 17,489 GWh in 2012. It is also thanks to this huge availability that, according to the GME report, the import flows of electricity have decreased, a certain convergence of the price between the hour groups has been facilitated, more in line with European standards and a reduction in puns in real terms has been achieved.
