inflation and the consequent disproportionate rise in the price of electricity has caused many companies to search for options to save on their bills. In this sense, the shared self-consumption It is presented as an efficient solution, especially since December, when Royal Decree 244/2019 was approved, which regulates the administrative, technical and economic conditions of self-consumption of electricity and which, in addition, allows it to be done in medium voltage line supply points.
For its part, iSiMAR, a furniture manufacturing and design company from Navarra, was clear that they needed to switch to self-consumption, not only because of what it meant for economic levelbut because it is also an important emission savings that translate into a benefit for the environment.
For the installation project of 1,352 panels with a total power of 600 kW and a cost of almost 400,000 euros, iSiMAR decided to rely on the experience of Contigo Energía, a Spanish company specializing in the installation of photovoltaic self-consumption, who has been by their side since The principle is offering advice and carrying out all the necessary procedures, and that is that this installation has a novel peculiarity: the company will sell the surplus to other companies in the area.
The idea arose when the Contigo Energía team saw that the area available to the company to carry out the photovoltaic installation was greater than what they needed for optimal annual consumption, so they were asked to sell the energy they did not need.
“My partner and I have always had a great interest in clean energy and the benefits it provides” said Eduardo Ruíz de Velasco, partner at Isismar “The decision we made to install solar panels in all our facilities has allowed us to considerably reduce costs energetic. We are also happy to be able to share surplus energy with our neighbors.”
At first, as the surplus could not be compensated because it was more than 100 kW, and exceeded the limit allowed at that time (prior to the approval of RD 244/2019), they were proposed as a solution to sell the surplus to the grid.
Rethink the project
But in December, after the approval of the Royal Decree on self-consumption that changed everything, they were proposed to rethink the project and sell the surplus surrounding companies, since in addition to the savings that the installation represents for iSiMAR (between 30% and 40%), we must add the profit it obtains from the sale of the surplus.
In this sense, the Navarrese company, the sole investor in the facility and, therefore, owner, has been in charge of contacting and individually agreeing on the conditions with neighboring companies, that will save between 10% and 20% on your bill, in addition to lowering the price of your kWh.
In addition, the installation will generate about 824,000 kW/h, which is equivalent compared to the electrical mix to about 226 tons of CO₂ per year.
“We are very satisfied with our work with iSiMAR” said Jorge González Cortés, president of Contigo Energía “The project is one more example of the future of energy consumption and the multiple benefits it brings, both in terms of energy cost and for the environment.”
The only legal condition for this model is that all participating companies must belong to the same marketer. Something very easy in this case, since the parent company of Contigo Energía is Gesternova Energía, which has sold electricity exclusively from 100% renewable sources since 2005. In addition to billing, the energy company is in charge of assigning energy coefficients to each of the companies participating in the distribution, in addition to taking care of all the necessary steps so that iSiMAR can sell the surplus.
