“In April, the government gave the green light to the royal decree regulating the conditions for self-consumption of electrical energy, after repealing the sun tax in October.

Until this moment, a citizen who had installed solar panels in his house could pour the surplus energy into the network, but he did not charge for it, unless he became almost a businessman. With this new framework, the idea was to encourage residents to install their own installations in order to produce and consume their own energy, and it seems that this objective is being achieved, as pointed out by Univergy, one of the companies that is promoting self-consumption installations in the province: “An investment of between 4,000 and 6,000 euros in a house allows savings of between 30% and 40% on the electricity bill”, explains Juan Felipe Pérez, Univergy’s commercial director, who calculates the amortization of the investment in an average of six years.
The new legislative framework has acted as a catalyst for new projects and the president of Univergy, Ignacio Blanco, assures that the installation of solar panels is growing exponentially throughout the country and that Palencia is not exempt from this trend. However, this increase in the number of households producing their own energy will not affect the large clean plant projects that will be installed in Spain after the decarbonization and the announced closure of the nuclear plants. “The data that are predicted indicate that between 200 and 400 megawatts will be generated over the next nine years by self-consumption facilities. Large plants can generate 500 megawatts. Self-consumption will be a trickle-down that will allow families to save, but this model will not replace large projects,” explains Blanco.
The big problem with self-consumption solar installations lies in the impossibility of generating energy at night. The lack of a sustainable technology in the economic aspect that allows accumulating the energy of the day to be used at night makes installations with batteries unviable. “The batteries that are now on the market have a price that makes their installation unviable. They are dropping by 20% a year and are only being installed in isolated areas, without electricity lines. The price will go down and that will be the next step in this world, which is in continuous evolution,” stresses the president of Univergy, which plans to bring self-consumption to 6,000 Spanish homes in 2020.
