BarcelonaThey knew in depth how the electricity market in Spain works and took advantage of its own "safety mechanisms" to defraud it. The fraud exceeds 61 million euros, according to Red Eléctrica's calculations, and there are 93 affected companies that are now trying to obtain compensation to recover the money they lost with this deception. The National Court will try this network between October and November, which operated from Barcelona and Madrid and was supervised from the Sarrià office where the businessman Esteban Roig worked, whom the Prosecutor's Office identifies as the director of the entire structure and requests that he be sentenced to sixteen years in prison. Sixteen more people are also accused, who could face sentences of between nine and six years depending on their degree of involvement.

As the Prosecutor's Office states in its indictment, the accused opened at least thirteen energy marketing companies and allegedly organized themselves not to pay producers for the energy that they themselves charged to final consumers. The deceptions began in 2012 and were uncovered at the end of 2017, when the main accused was arrested and spent a year in provisional prison. Among the most affected energy producers are Endesa with 19.83 million, Naturgy (7.29 million) and Repsol (4.84 million).

They took advantage of the system's own operation: since electrical energy cannot be stored, marketers usually buy from producers the amount they anticipate they will need to cover customer demand, but if at any time they need more than anticipated, it can be covered with "adjustments" or "deviations" that were the key to this millionaire fraud. Normally, these adjustments account for less than 10% of the energy ultimately supplied to end users, and sometimes they force producers to increase production. Due to the way the system works, it is not possible to know which marketer specifically is responsible for this energy that had to be produced in excess until about eight months have passed. Meanwhile, marketers can invoice customers for everything they have supplied thanks to the meters.

This pause of a few months was the loophole for fraud, according to the prosecutor. Non-payment to producers entailed an investigation by the National Commission of Markets and Competition (CNMC) that would end with the company being disqualified and expelled from the state electricity system, but in any case, the non-payment would have already harmed not only the producers: the unpaid "deviations" end up being passed on to the final price of energy, so that the final consumer ends up bearing them.

Hide the money

The first step was to create the trading companies and quickly attract customers by offering very low prices. At the same time, this forced more and more "diversions" and an increase in energy production. Once this first period of customer acquisition was over, they began to reduce the amount of energy they bought each day. They reached the point of buying only 5% of what their customers would request, so the amount of energy the end user paid for grew, but the system never collected.

Although Red Eléctrica warned of the non-payments and the CNMC investigated and disqualified the companies involved, the network was prepared to evade these sanctions with a complex corporate structure, according to the indictment. Thirteen trading companies are being investigated in the case, but many more were involved in the network. According to the Prosecutor's Office, about forty, including management companies and shell companies. They themselves diverted customers to a new company, also related to the network, when the first one was about to be disqualified. Furthermore, part of the funds obtained by the thirteen trading companies were transferred to other companies linked to the network to hide them, some administered by the accused themselves.

The trading companies' operations center was in Madrid, but the network also had other companies based in Barcelona. From the Catalan capital, they operated in different commercial sectors and were fed by funds from the illicit sale of energy. In fact, the headquarters in a building in the Sarrià neighborhood was the "link between the fraudulent trading companies and the rest of the organization, which gave an appearance of legality to the executed activities," explains the prosecutor.
