Spain’s Power Bill: Renewables vs. Germany, the Truth

A message attributes to renewables paying less for power than Germany

Spain’s electricity bill has become the star argument for those defending the renewable rollout. A viral message on social media claims Spain pays nearly three times less than Germany or Italy for power, even with the hike caused by the war in Iran, presenting it as the system’s lifebuoy. This figure has reignited a long-standing debate: does the renewable mix truly lower the bill, or does the credit belong elsewhere? In the context of a European energy crisis marked by the closure of the Strait of Hormuz, the data serves both to defend and question the model.

What the data says and what it hides

The starting message is clear: with renewables, Spain withstands the blow better than its neighbors. Some attribute this to hydropower, not solar or wind. A recurring analysis notes that this has been a particularly rainy year with full reservoirs, which has pulled down wholesale prices. The trick, according to this reading, is lumping together very different technologies and presenting the result as merit for the whole.

In response, official arguments insist that the renewable rollout is what makes the difference and that gas for electricity generation will disappear. Planning targets 80% renewables by 2030 with massive battery storage. It is a promise with a date, and promises with dates are what eventually get paid.

The scam is the model, not the technology

The sharpest argument does not attack the panels, but the system built around them. They were installed with premiums and subsidies paid by everyone’s bill, creating the famous tariff deficit. They were given absolute dispatch priority; they enter the grid no matter what, even if combined-cycle plants that were already paid for must be shut down. This distorts the wholesale market and raises costs during certain hours.

The defense of the model responds that the cost of newly installed solar in large plants is around 30-35 €/MWh, with room to not utilize some hours. The problem is not the cost of generation, but who pays for the infrastructure and how it is distributed.

Winter still belongs to gas

Here the analysis stalls. Current batteries, with an average of 3.3 hours of backup, cover summer and part of spring and autumn. Not winter. Hydropower is already at its limit, and wind depends on the breeze. Anyone trinc December data knows: more gas. The question is how much and at what price.

Nuclear vs. panels: the clash of land occupation

The other front is territorial. Panels occupy 0.2% of the territory, according to one side, with photovoltaic plants being points on the map. The other side speaks of 47,000 hectares of agricultural land and 15,000 of deforested or burned forests for windmills, versus 1,200 hectares sufficient for nuclear to produce double the energy stably. The complete calculation, broken down by technology and surface area, reveals a surprising difference.

International comparisons also appear: some European countries are planning or building nuclear, even Denmark considering removing the ban. And the German case is used as a warning: it closed nuclear and thermal plants, relied on Russian gas, and when that gas disappeared, they were left stranded.

What still does not add up

With these differentials, industrial migration should be massive toward Spain. It remains marginal. No one fully explains why the bill drops and companies do not arrive in the same proportion.
