Collective self-consumption to increase incentives for photovoltaics
[ad_1]
Panels on the roof of the condominium and collective self-consumption. For those planning Superbonus interventions, installing a photovoltaic system is still convenient, even if the deduction rate is reduced to 90%, and the advantage increases significantly if you decide to opt for collective self-consumption. A sort of mini energy community at the level of the building, with a much more streamlined activation procedure, since it is reserved only for the inhabitants of the building, the possibility of collecting the incentives and selling what is not consumed. To know all the advantages of a configuration of this type of intervention of this type, Enea provides a RECON, a new tool for evaluating costs and benefits for collective self-production.

Incentive and free sale
According to current rules, self-consumers of renewable energy must be in the same building, in the same building, or condominium, or in any case nearby. This type of plant does not constitute a normal commercial activity, for which there is no form of taxation on the energy produced and consumed directly, and in addition it is possible to access the Superbonus as a driven intervention. The tax bonus is applied to the cost of the system up to a power of 20 kW, while for the additional portion (always in any case within the ceiling of 200 kW) the deduction equal to 50 percent of the expenses is due up to a maximum amount of 96,000 euros referring to the entire plant. The decree on the CERs currently under consultation confirms the incentive of 100 euros/MWh for condominium self-consumption and the supply for a period of 20 years if the share of shared energy is equal to or greater than 70% of the energy produced. In this case, the residual amount of energy can be freely sold by the producer. If consumption is lower, however, the incentive is reduced.

The simulator for convenience calculations
To find out the actual convenience of shared solar at the condominium level, Enea is making available a new simulator, RECON (Renewable Energy Community ecoNOmic simulator – Tool for the economic evaluation of Renewable Energy Communities). It is a web application created by ENEA and aimed at supporting preliminary energy, economic and financial assessments for the creation of renewable energy communities (CERs) or self-consumers of renewable energy. RECON can be used for free upon registration.
Consumption data
On the basis of a limited set of inputs – information on the building-plant, electricity consumption obtained from the bill, characteristics of the RES production plant and some economic-financial parameters – RECON carries out an energy and economic analysis for the evaluation of the investment, considering different forms of financing, eligible tax deductions and incentives. In the event that the electricity consumption from the bill is not available, the simulator estimates them on the basis of ad hoc implemented algorithms considering separately the contribution of the single end use (driving power and lighting, heating, cooling, DHW production).
