The latest blackout that left thousands of homes and businesses without power on April 28 has triggered A series of changes in the operation of the Spanish electricity system are reflected in electricity bills. Despite warnings that the increase would be temporary, both regulated market and fixed-term contract users are experiencing an increase in amounts this summer.
La uncertainty The lack of clear explanations about the cause of the outage, along with the introduction of new terms on bills, leaves consumers in a defenseless situation, with no one responsible to complain to and facing higher bills in the coming months.
Why did the price of electricity go up after the blackout?
The key is in the "reinforced operation" that Red Eléctrica has launched after the April incidentIn order to guarantee supply stability and avoid another "energy zero," the grid operator has increased the weight of gas and nuclear energy in the energy mix, partially relegating renewable energy production. This decision, according to data from various consumer associations and industry spokespersons, has led to a significant increase in the cost of adjustment services, which previously had little impact and are now directly reflected in invoices.
The electricity employers' association Aelec and the Association of Independent Energy Marketers (ACIE) estimate that the security costs of the system, which were around 11 euros/MWh in April, have risen to 24 euros/MWh in May. According to Red Eléctrica, in just one month, technical restrictions have generated an approximate additional cost of 200 millones de euros, which are ultimately reflected in consumers and marketers.
Due, Families with PVPC rates have noticed the increase since May, as the price per megawatt hour rose from €18,4 in April to €29 in May. Those with fixed-price contracts have not been exempt either: many marketing companies have added the "System Adjustment Services" (SSAA) item to the bill or have communicated upward revisions, justifying them with this. "extraordinary event"Although the fine print usually grants the right to transfer these regulated expenses, a change in the contracted price is not always made official.
What measures have the electric companies taken?

According to different associations and portals specialized in energy saving, There are already marketing companies notifying increases to its customers and warning that the situation could be prolonged, given that Red Eléctrica has not confirmed how long the enhanced operating regime will last. The independent companies grouped in ACIE have also not received answers regarding when gas and hydroelectric power will cease to be prioritized in system management.
Major companies in the sector are proposing to the government that the nuclear power plant closure schedule be modified, arguing that continuing it could help stabilize the system and reduce price volatility. However, authorities insist that any changes must guarantee both security of supply and prevent skyrocketing costs for consumers.
How much has the bill gone up?
The impact on users' pockets is already palpable. According to the Organization of Consumers and Users (OCU), the average bill has increased between 5 and 8,5 euros per month per household since the blackout.The increased use of natural gas and new regulated items are driving up spending, and everything indicates that these additional costs could continue as long as the current cautious strategy in operating the system continues.
Furthermore, since January, the VAT on electricity has returned to 21%, following the end of extraordinary measures due to the energy crisis, which has contributed to higher bills in both the free and regulated markets.
Is there a way to avoid or reduce the impact?
Despite the difficulties, experts recommend review the conditions of the contracts and be aware of new billing concepts, especially during automatic renewal periods. Anti-fraud platforms like Zonox detect unexpected charges without sufficient communication from the companies.
Likewise, it is advised check the cheapest hours of the day When using high-consumption appliances (washing machine, dishwasher, air conditioner), concentrate their use during these periods, adjust the contracted power, avoid standby mode, and choose cold wash programs as measures to reduce costs. Don't forget to review your monthly bill in detail to detect possible overcharges.
How long is this situation expected to last?

For now, neither Red Eléctrica nor the Government have given a precise timeline for when the reinforced operation will end. Most experts predict that Extraordinary costs could continue for much of the summer, especially if demand remains high and fears of further blackouts persist. Uncertainty about the future of nuclear power plants and the debate over supply security also contribute to the possibility of prolonged changes in bills.
Consumers are facing new price increases, a changing regulatory environment, and the need to be better informed about the details of their contracts and bills. The combination of the April blackout, technical adjustments, and tax increases has tested both the patience and the wallets of many families, so it's advisable to be vigilant and compare options to avoid paying more than necessary.
