The electricity bill continues to cause headaches for millions of Spaniards. After a year marked by unexpected price increases, blackouts, and price volatility that has left families reeling. Add to this the heat waves and an unstable international context, electric bill It is once again emerging as one of the main household expenses, testing the resilience of household economies and the patience of users.
During 2025, the electricity bill has experienced strong variations, reaching an average increase of 12% in June, according to data from the OCU. The causes are multiple: from the impact of extraordinary events such as the national blackout in April, to structural factors such as the drop in renewable generation and a demand surge due to high temperatures. All of this has a direct impact on the family budget, with the monthly bill exceeding 67 euros on average in homes with regulated tariffs (PVPC), and also with effects on those with contracts in the free market.
The impact of the blackout and rising prices
The blackout last April left its mark on the electricity bill.. Although supply was quickly restored, the impact on costs has persisted for months. According to the OCU and other observers, wholesale market prices They shot up to 72,6 euros/MWh in June, compared to just €19,13/MWh the previous month. This jump, a 279% increase, has meant that typical households with an average contracted power saw their bills rise from €60,44 to €67,43 in just one month. Users of both regulated tariffs and the free market have felt the impact, turning the bill into a daily problem that erodes annual savings.
There is no single person responsible for this price increase.Following the blackout, renewable energy generation—especially wind and hydroelectric—dropped sharply, forcing greater reliance on more expensive and polluting energy technologies. Furthermore, the stifling heat of June and the early arrival of the first heat wave of the summer caused a notable spike in consumption, especially due to the use of air conditioning. This combination has led to skyrocketing electricity bills just when the burden on household budgets is most needed.
The electricity bill, well above that of our European neighbors
Spanish industry bears a much higher electricity bill than its European competitors.According to the latest barometer from the Association of Companies with Large Energy Consumption (AEGE), the cost for an electro-intensive industry in Spain is 172% higher than in France and 48% higher than in Germany. This is mainly due to the fact that Spanish customers face additional costs such as adjustment services, tolls, and lower compensation for CO emissions.2 compared to their European counterparts. This difference not only penalizes competitiveness but also indirectly impacts the end consumer.
Extreme heat and electricity bills: the effects of climate change
Climate change is multiplying household energy costsA recent report by the consulting firm Raisin reveals that the increase in heat waves in Spain has caused annual household spending on air conditioning to double, from €130 to €260. Nationally, this represents an additional cost of about 2.500 million euros per year Only through the use of air conditioning systems. Air conditioning has ceased to be a luxury and has become a basic necessity, especially when maximum temperatures exceed 40 degrees and minimum temperatures never drop below 25 degrees.
How to save on your electricity bill?
In a market with increasingly volatile prices, comparing rates and adjusting consumption is key.. According to the OCU, the annual difference between choosing the best and worst rate can reach 500 euros in a typical year. It is advisable to take advantage of the cheapest hours During the day (usually at night and on weekends) for intensive use of household appliances, such as the washing machine or dishwasher. Keeping the air conditioning temperature at around 26°C helps reduce consumption by up to 7% for every degree raised.
The regulated market (PVPC) has reformed its calculation system, gradually incorporating medium- and long-term prices to smooth out daily fluctuations and encourage efficient energy use. By 2025, 40% of the regulated tariff price will be based on the futures market. Furthermore, it is important to review the contracted power, use LED bulbs, keep appliances in efficient mode, and unplug standby devices.
There are also programs and aids, such as the Electric Social Bonus, which offer temporary discounts of up to 65% for severely vulnerable consumers. Regularly reviewing the terms and conditions and seeking advice on the available options can result in significant savings on your bill.
