What is shared self-consumption? And why not in industrial parks?
Today in Enertika’s blog we will talk about what is shared self-consumption. How can different users or organizations take advantage of it? Does it only apply to communities of neighbors or are there more? What type is best suited to your needs? We will answer all these questions and more below.
What is shared self-consumption and how it works in short
To begin with, what is shared self-consumption? It is one of our favorite models of photovoltaic self-consumption because of its richness of possibilities and advantages, and above all because it still has a lot of potential to exploit.
It consists of an energy system that allows several participants to consume energy from the same photovoltaic installation. In fact, more than one solar plant can supply electricity to consumers.
However, there are a number of requirements that must be met in order to implement shared self-consumption: the power distribution must be at low voltage. The users must be within a maximum distance of 500 meters from the installation and must be registered under the same cadastral reference.
Who can benefit from collective self-consumption?
Although the first example that comes to mind when we think of collective self-consumption are the communities of neighbors, it exists beyond this consumption group. Obviously, neighborhood communities are ideal in terms of meeting the requirements, especially in terms of low voltage distribution. But now we will focus on other users that can benefit from collective self-consumption: industrial parks.
The energy transition is imminent in industry to meet the objectives of the Paris Agreement and Agenda 2030. Most of all, because otherwise they will be penalized. Shared industrial photovoltaic self-consumption is a very interesting option, as it allows industrial estate warehouses to take advantage of the energy that other companies do not use according to their consumption schedule.
Types of collective self-consumption: which one is best
As we have repeated on several occasions, there are no better or worse self-consumption systems, what we must take into account is which ones are best suited to your needs. And if you want to know more about the different modalities, click to read the previous blog.
Collective self-consumption without surplus
The photovoltaic installation does not feed into the grid, i.e. the surplus energy does not go to the grid. This is why this modality can be considered the installation of energy storage batteries. Ownership of the solar plant is shared among all the users or organizations that enter into the agreement.
Collective self-consumption with surpluses not subject to compensation
The users agree that the surplus (energy not consumed) is sold to the market. In this case, however, ownership of the photovoltaic installation belongs to the producer and an essential requirement is that the solar plant must have an installed capacity of more than 100 kWh.
Collective self-consumption with surpluses with compensation
The last modality to be considered is shared self-consumption with surpluses. The supplier will see that the energy not used is compensated in the bill at the end of the month. And it is a prerequisite that the installed power is less than 100 kWh.
Our success story: Rubí Brilla
Finally, we would like to share with you one of our success stories: the first shared self-consumption system in an industrial in Spain. It is a project promoted by the Rubí City Council and its program Rubí Brilla. The initiative was born from the following premise: Rubí has the largest industrial concentration in Catalonia after the Zona Franca, which produces 40% of the city’s emissions.
Different companies in the city joined the photovoltaic self-consumption when the project started, and today more industry is still joining. Initiatives such as this demonstrate the real potential of shared self-consumption beyond the neighborhood communities. If you want to know more, click here to see the full article.
