Thousands of households affected by the massive power outage that hit Spain and the Iberian Peninsula on April 28, 2025 may be entitled to compensation on their electricity bills, but many customers say they still have not seen any discount applied months later.
Consumer association FACUA has now launched a campaign encouraging affected users to formally claim the money they believe electricity distributors should already have credited automatically.
The organisation argues that Spanish regulations require compensation when power cuts exceed certain service quality limits and says some consumers could also claim additional compensation if companies fail to respond within the legal deadline.
For many households that spent hours without electricity during the blackout, the issue is now turning into a battle over who should pay for the disruption and whether electricity companies are complying with their obligations.
Who can claim compensation after the Spain blackout
According to FACUA, the campaign is aimed at electricity customers who lost supply during the major blackout and have not received any reduction on their bill linked to the interruption.
The claims are directed at electricity distributors rather than energy suppliers. In Spain, the distributor is the company responsible for maintaining and operating the electricity network in each area.
FACUA says the compensation system is already covered under Spanish legislation.
The association points to Royal Decree 1955/2000, which establishes that distributors must apply discounts when electricity supply continuity standards are not met.
The regulation also makes clear that distributors remain responsible for quality indicators linked to their networks, even if they later try to recover costs from other operators involved in the incident.
FACUA argues that many customers should not have needed to request the discounts manually because the reductions were supposed to appear automatically once service thresholds were exceeded.
The organisation has already filed complaints with Spain’s National Commission on Markets and Competition against several distributors including i-DE Iberdrola, UFD Naturgy, e-Distribución, Viesgo Distribución and E-redes.
How much money households could receive
The compensation amount is not fixed and depends on several factors including the contracted electricity capacity, the length of the outage, the type of area where the property is located and the customer’s tariff conditions.
FACUA explains that the calculation uses the contracted kilowatt capacity multiplied by five times the average annual electricity price per kilowatt hour consumed.
That figure is then adjusted according to the number of hours without electricity, although the formula deducts a certain number of hours depending on whether the property is located in an urban, semi urban or rural area.
The association provided an example using a household with 4.4 kilowatts contracted, 12 hours without power and an average electricity price of €0.1491 per kilowatt hour.
According to FACUA’s calculation, that household would be entitled to around €22.96 before taxes, rising to approximately €25.38 once taxes are included.
For some customers the final amount could be higher or lower depending on their individual situation and the duration of the outage in their area.
While the compensation itself may not seem huge for every household, FACUA argues the principle matters because service interruptions affected large parts of Spain and disrupted daily life for millions of people.
Why some households could claim an additional €30
FACUA says there may also be another layer of compensation available in certain cases.
According to the organisation, if the distributor fails to answer the customer’s complaint within five working days, users with contracts below 15 kilowatts may be entitled to additional compensation.
The amount established under the regulation is €30.050605 or 10 per cent of the first full electricity bill, depending on which figure applies.
That possibility has drawn fresh attention because many customers claim they still have not received clear explanations from electricity companies regarding the blackout and possible compensation.
FACUA has published a template letter that consumers can complete and send directly to their distributor. The document asks the company to confirm whether the outage was officially recorded for supply quality purposes, whether the legal service limits were exceeded and whether compensation will be included on the next bill.
Consumers are also asked to include personal details, identification information, their supply contract reference and the CUPS code linked to the affected property.
The blackout is still raising questions months later
The April 2025 outage became one of the most disruptive electricity incidents affecting Spain in recent years.
Beyond the immediate chaos caused by the loss of power, the blackout has continued generating political, regulatory and consumer pressure as questions remain over responsibility, infrastructure resilience and compensation. For affected households, however, the issue has now become much more practical.
Many simply want to know whether they are legally owed money and how to claim it. And with FACUA now publicly encouraging consumers to take action, electricity distributors could soon face a wave of new complaints from customers checking their bills more closely than before.
