Spain's Solar Record Fails to Cut Average Electricity Bill 2026

Spain's record solar generation has not translated into lower electricity bills for the average PVPC consumer, whose monthly bill exceeded €104 in September. Photovoltaic energy led the country's power mix for the sixth consecutive month, according to FACUA-Consumidores en Acción, yet the regulated tariff bill climbed to €104.31, the highest in four years.

The paradox matters because PVPC, the regulated tariff, covers 8.2 million consumers—27.4% of all Spanish electricity users. Even as the cheapest technology dominates generation, inflation and market dynamics are pushing household costs upward.

What the FACUA Report Reveals About the Average Electricity Bill

FACUA's study shows the average PVPC user's bill rose nearly €40 in just five months, from around €65 in April to €104.31 in September. That represents a 28% increase compared with September 2025, when the same bill was €57.85, and a 7.9% jump from August's €96.65.

The last time bills were this high was 2022, during the energy crisis triggered by Russia's invasion of Ukraine, when the average PVPC bill reached €137.93. The current upward trend began in May and has continued without interruption.

To calculate these figures, FACUA uses a standard profile: a contracted capacity of 4.4 kW (same for peak and off-peak hours) and a monthly consumption of 366 kWh. This benchmark helps compare month-to-month changes and understand how price shifts affect typical households.

Why Solar Records Don't Automatically Lower Bills

Solar photovoltaic energy may be the cheapest source of electricity, but it does not set the final price paid by PVPC consumers. The regulated tariff is tied to the wholesale market, where prices are determined by the most expensive technology needed to meet demand—often natural gas or other fossil fuels.

This marginal pricing system means that even abundant solar power can coexist with high wholesale prices. Additionally, other cost components—such as network charges, taxes, and renewable subsidies—are included in the PVPC bill and can be influenced by inflation.

Seasonal factors also play a role. In September, solar output begins to decline from summer peaks, while demand may remain high due to cooling needs or economic activity. The combination of lower solar production and volatile gas prices can push wholesale prices up.

Key Takeaways for PVPC Consumers

• The average PVPC bill reached €104.31 in September, the highest since 2022.
• Bills have risen nearly €40 over five months, driven by inflation and market dynamics.
• Solar generation records do not directly translate into lower regulated tariffs.
• PVPC covers 8.2 million consumers, representing 27.4% of all Spanish electricity users.
• The upward trend started in May and shows no sign of reversing yet.

Who Is Affected and What to Watch Next

The 8.2 million PVPC consumers are directly exposed to these price swings. Unlike fixed-price contracts, the regulated tariff fluctuates with the wholesale market, making budgeting difficult. The increase is particularly painful for low-income households, which are more likely to be on the PVPC tariff. The background to this story is set out in Energy Utilities: latest articles.

Looking ahead, several factors could influence bills. If solar generation remains strong and gas prices stabilize, wholesale prices might ease. However, inflation in other components of the bill could offset any relief. Government interventions, such as tax cuts or subsidies, are also possible but not guaranteed.

Consumers should monitor monthly PVPC prices and consider whether a fixed-rate contract might offer more stability. Energy efficiency measures—such as shifting consumption to off-peak hours—can also help reduce costs.
