Eight questions and answers on the new norms of the electrical self-consumption

Ocho preguntas y respuestas sobre las nuevas normas del autoconsumo eléctrico



The government gave this Friday a green light to royal decree which regulates the administrative, technical and economic conditions of self-consumption of electric power in Spain, after repealing the sun tax in October. Until now, a citizen who had put an installation in his house could pour the excess energy into the network, but he did not charge it, unless he became almost an entrepreneur. The new regulations aim to encourage neighborhood communities, business parks, university campuses or other users to place their facilities in order to produce and consume their own energy.

According to sources of the sector, the prices of the facilities go from 4,500 euros for a house that puts in its terrace a photovoltaic system of 3 kilowatts, up to 6,000 euros for a single-family house. Both facilities can be amortized in about seven years, although the useful life is about 25 years. One of the main novelties is that if you end up depositing the excess energy to the system, the marketing company will compensate it in the electricity bill for the following month. It must be remembered that in the receipt of electricity, 40% corresponds to energy consumption and 60% corresponds to transport, distribution and taxes. From now on, up to 100% of the first game can be compensated. Today, there are no batteries so powerful to accumulate energy in the home, with which the surplus must be deposited necessarily in the network.

In addition, the new royal decree seeks to promote self-consumption shared among different urbanizations depending on which has for example better guidance, to obtain better solar energy, and proximity consumption.


How is it compensated?

Until now, if the self-consumer wanted to obtain financial compensation for the energy that was injected into the network, it should be constituted legally as an energy producer, carrying out the procedures and tax declarations that the law required. With the royal decree approved yesterday, the energy marketer will compensate the user for the surplus energy in each monthly invoice.


Who can benefit?

This mechanism is applicable for installations with a power not exceeding 100 kilowatts (kW) and provided that electricity is produced from renewable energy. The financial compensation can reach up to 100% of the energy
consumed by the user in that month.






How will the shared self-consumption be?

The royal decree opens the door for a consumer to take advantage of the surplus of his neighbor and coparticipate self-consumption, if this is not consuming its proportional share of energy.


What procedures are reduced?

The new standard reduces administrative procedures for all users. In the case of small self-consumers (installations of up to 15 kW or up to 100 kW, in case of self-consumption without surpluses), they are reduced to a single management: notify the installation of an electricity production plant to the city or autonomous community. The state registry will be powered by the information sent by the regional administrations. In addition, for installations with less than 100 kW in low voltage, administrations will collect information from the data of the installation's electrotechnical certificate.


How does the new standard classify consumers?

Until now, there was only one possibility: individual self-consumption connected to an internal network. With the new standard, the figure of collective self-consumption is consecrated, in such a way that several consumers can be associated to the same generation plant. This reality will boost self-consumption in communities of owners or between companies and industries located in the same location.


How will the citizen know the steps for processing?






The Institute for Energy Diversification and Saving (IDAE) is already working on a processing guide that will be available in the coming weeks. For installations of up to 15 kW there is no need for paperwork with the electrical distributor, but it is sufficient that the professional who carries out the installation registers it with the energy or industry departments of the autonomous community. The community will notify the distribution company that the installation has been made.


How do you know which is the best option?

From the approval of this royal decree, the electric companies will design and offer new products to consumers in this direction. The first thing is to compare different options and see which one is the most suitable for each consumer based on their electrical profile, meters of the roof of their home ... Once the company that is going to do the installation is selected, it is most likely that this company is in charge of all the procedures before the Administration.


How will the maximum savings be achieved?

In order to achieve maximum savings, it will be necessary to try to match consumption to electricity generation. However, thanks to the compensation mechanisms, you can take advantage of even the energy that is spilled at times when you are not at home. It is advisable to have a maintenance service contracted. Regulated marketers will be obliged to make the compensation simplified, that is, to compensate for the energy that is left over some hours of the day, with what is lacking in others. The free market are not required to offer that option, but customers can always change.
