IBERIAN PENINSULA — Spanish households saved an average of €10 per month on electricity bills in 2026 due to an expansion of wind and solar power capacity between 2022 and 2026. This expansion insulated them from rising natural gas prices.

Natural gas influenced wholesale electricity prices in Spain 52% of the time in 2021. By the first five months of 2026, this dropped to 9% of the time. Electricity prices in Spain showed minimal correlation with increased natural gas prices in 2026. Chris Rosslowe, an energy analyst, said: "We just had a 60% rise in gas prices and electricity bills in Spain basically haven't reacted – they actually got a bit cheaper in April. That's a clear and obvious contrast to the previous gas crisis, when electricity bills were climbing immediately."

Wind and solar power generated 33% of Spain's electricity in 2021. This share increased to 42% by 2025. Household electricity bills in Spain would have cost 19% more if pricing had remained linked to natural gas at 2021 levels. An analysis used electricity market data from March and April 2026 and modeled household costs using a regulated tariff applicable to approximately one-third of Spanish residences. The analysis included balancing costs for generation fluctuations but excluded grid infrastructure upgrades.

Mar Reguant, an energy economist, said: "There is no question that Spain and Portugal are greatly benefiting from their early transition. The Iberian peninsula has a privileged position and has acted smartly." Gas-fired power plants in Spain establish wholesale electricity prices during specific high-demand hours. Diego García Gusano, an energy researcher, said: "Spain is less exposed to gas shocks than other countries, but it is not immune. The bet on renewables is very sound, but much more is needed to make that bet structural and not circumstantial." Frequent periods of very low wholesale electricity prices are reducing financial incentives for new renewable energy investments in Spain. Additionally, limited deployment of energy storage and inflexible electricity consumption patterns reduce the grid's capacity to absorb surplus renewable generation.
