5 improvements of the new Guidelines for self-generation
The past April 2019, within the change in Guidelines and Regulations commonly known as «Ley de autoconsumo» or «Impuesto del sol» (Self generation Law or Sun tax), the Govern bid for a long term plan to propel the Energy Transition.
It is possible to sum them up and simplify the 5 key points as follows.
Tax cancellation (for energy generated by solar PV systems)
«The consumed energy from renewable sources», as the Regulation states, «will be free from all kind of charge and toll».
To propel the adoption of electricity from photovoltaic systems, the Govern decided to cancel the tax charging the energy produced by this sort generators at domestic and Small and Medium Enterprises level.
At the same time, this step intends to trigger the generation of electricity from renewable sources, which currently is between 25% and 30% in the whole electricity production balance. So that this induces to reduce the contaminating source dependence (in Spain, 14% of production comes from coal plants, 22% from nuclear, 12% from co-generated and finally 11% from combined cycle).
Exceeding production sale
In the new legal framework, despite of not being fully broken down in details, it is possible to 2 self generation models: with or without surplus.
The first, all the generated energy is used to respond to generator’s own needs and none of that is to be injected to the Energy Grid.
The second case is that the exceeding amount of energy – as that generated, but not yet consumed by domestic appliance, for instance – can be stored in battery if available, otherwise ingested back to the Grid. The consequence is that the generator benefits from its sale (at the price that he negotiates with the Utility Firm) and this is to be reflected into a lower bill. The highest extent will be a «zero-balance», as he will be invoiced by 0€ to be paid, as the generation compensation balanced the consumed counterpart.
Energy Community and end users
The new Regulation admits the solar PV installation in houses or combo building. This measure is relevant, for the fact that it was estimated that 2 out of 3 people in Spain live in apartment.
This implies that the neighborhood can agree to share the energy generated from the installation, accordingly with a fix percentage among the parties.
To reach an agreement among neighbors, it suffices to get one third of the landlords, on the condition that it represents at least of the quota, as defined in artículo 17 la de Ley de Propiedad Horizontal.
The most venial consequence is that the aesthetics of the cities will change, whilst the deepest one is spreading of culture of a more sustainable collective consumption. This is the most impactful and meaningful aspects to be taken in consideration, apart from the economic reasons.
Then it matters to ask yourself what sources the electricity you use was generated from, and what are your consumption habits: The Utility Firms never answered to clearly and with details.
On top of that, the amount you need to pay in your energy bill corresponds to the cumulative provision of energy, accordingly with the hourly ranges of tariffs agreed in the contract between parties.
Moreover, you will not receive any details of the amount of energy you consumed on July 14th, for instance. The Utility Firm is not prepared yet to satisfy this clarification request, but from now on it is a right of any consumer to ask for it and to pretend an answer back, in order to be able to adopt any kind of sustainable measure in using resources.
Installed power system
The approval of Real Decreto 15/2018 determines a before and an after between the admitted installed power in a generation system: until then, it was not possible that micro generation ones had had a peak power greater than the contracted one with the Utility Firm. In Spain, from April 2019, the only limit is the surface available on the rooftop.
The new Guidelines states that new generation system installers are «not obliged to obtain permission of access and connection» either for self consumption installation without surplus and «for those with a production inferior to 15 kW located on urban areas compliant with the services requested by the Urban Regulation».
For this reason, the formality is reduced to installation certificate for solar PV system and to acknowledge the Community and the Distributor or the Utility Firm.
Nevertheless, it was declined the obligation to install a second meters only for energy generation, except for collective ones.
The last but not the least, you don’t need to certify any work to install solar PV, unless the installation infringes any security level. This will be the duty of any installer.
