district resistance to electricity to save 30% on the bill – CVBJ

Created under the concept of self-consumption, town halls or cooperatives create communities to develop projects that guarantee cheaper and green energy.

Energy Community in Realengo (Alicante) .EM

El Realengo is a train station in Crevillente (Alicante) which recorded 307 inhabitants and 65 houses. Everyone will pay between 20% and 30% less on their November electricity bill. The reason is that they are part of an energy community or, in other words, they have gone from mere consumers to producers and managers of their own electricity. It is the concept of a figure which proliferates in Europe and which arrived in force in Spain where, according to the Institute for Diversification and Energy Savings (IDAE), An energy community is an entity made up of partners (neighbors, SMEs or even municipalities) “based on open, voluntary, autonomous and controlled participation by partners located near their own renewable energy projects”.

In Europe, there are 1,800 self-consumption communities in Germany, 700 in Denmark and 500 in the Netherlands. In Spain there is already a around thirty projects in progress, a third of which is in the Valencian Community, although no national legislation has yet been developed to protect them beyond the European directives on renewable energies and electricity markets.

The community can be constituted promoted by a town hall, by neighborhood communities or even by companies from the same industrial zone. The only limit is that collective self-consumption facilities are located in a radius of 500 meters. The estimated savings are between 20 and 40% because the electricity distribution networks are not used, which reduces costs and taxes, and during the day the produced energy is consumed. At night, the option is to use the kilowatts that have been stored in batteries. Due to their high cost, there are some communities that choose to install them and others that go online. Although most communities size their photovoltaic installations for their consumption, surpluses can be produced to cover the needs of families in the municipality in a situation of energy poverty or be sold to third parties.

The energy community of Crevillente is called Comptem, is the first collective self-consumption cell. It is promoted by the city council itself and the Enercoop group, whose origin is the Cooperativa Elctrica Benfica San Francisco de Ass, which was born in 1925 to create a distribution network that would supply the textile sector for the production of rugs. when companies do not consider it profitable to shed light on a city which now has 30,000 inhabitants, 95% members. Like Enercoop, it is a distributor and marketer, but also a producer of 30% of the energy the municipality needs, through its photovoltaic and hydraulic installations. Light is cheaper there.

In El Realengo, they took another step. In a municipal land where there are sports and recreational facilities, they have installed a roof of 600 square meters of solar panels with a capacity of 180,000 kWh per year, which will cover 50% of the energy needs of the station. In addition, Comptem is part of an experimental project combining collective self-consumption technology and medium-scale energy storage, the Merlon project, which has a contribution of 300,000 euros out of the 400,000 investments made. The rest of the cost is borne by the members of the cooperative, allocating a percentage of the rebate they receive on their invoice to depreciation of the infrastructure. In other cases, such as the community promoted by the City of Abenjar (Ciudad Real) and RenoWa, a contribution of five euros is paid to become a member and benefit from savings estimated at around 40%.

The idea of ​​Enercoop is to be able to launch three new communities before the end of 2021, with the use of public (schools, medical offices, municipal offices, etc.) or private roofs, by weaving “bee panels” with the aim of than in 2030 “50% of the municipality’s energy is produced in the community”, they explain from the cooperative.

Saving the bill isn’t just a concern of families. Particularly serious is the increase in electricity prices for industries, which are also beginning to explore the benefits of energy communities.

The Safor Professional Association (AES) and the Federation of Professional Associations of La Safor (FAES), both with their headquarters in Ganda (Valencia) created the Polgono Alcodar Energy Community, one of the first initiatives in Spain to implement this model of collective self-consumption of renewable energies in an industrial area. The objective is to design a global strategy for the entire industrial zone, which brings together more than 200 companies, with the participation of all those who wish. In total, it is expected to reach an installed capacity of 8.8 MW, which is the largest project of this type currently underway in Spain.

To do this, they have the participation of Sapiens Energy, Valencian cooperative expert in this model of collective self-consumption, which has already promoted five energy community projects in municipalities in the province of Valencia, which maintains six others in progress and which advises municipalities wishing to promote them.

One of their collaborations goes beyond urban supply needs. As in the case of industrial zones, Sapiens Energa has gone further and with Transicin Energtica Solar (Tranesol) promote the figure of the Community of agrovoltaic or agro-photovoltaic renewable energies, a model that makes it possible to make agriculture or electricity. farming compatible with the establishment of a renewable energy production plant.

The first project, Picassent Solar, to be built at the end of 2021, consists of recovering the soil from a pig farm that had not operated for 40 years to install 11,000 square meters of plates in height, with up to 4 meters in height. in certain areas, so that tropical fruits can be planted underneath. With this installation, farmers and some 500 users – households and SMEs – who are within a coverage radius of 50 kilometers around the installation will be supplied, in addition, a reduction of 1,920 tonnes of CO2 emitted into the atmosphere. will be carried out.

These investments in the Valencian Community, which have been multiplied by seven in just one year, have been made possible thanks to the aid promoted by the Valencian Institute for the Competitiveness of Enterprises (IVACE) which reaches two million euros and which receives a new impetus with European funds.
