Spain and Portugal: When Solar Power Is Free on Certain Days

A fascinating phenomenon is taking place in Europe in 2026. In some countries, solar power generates so much energy that electricity literally becomes free—or even costs less than nothing. This is the case in Spain and Portugal. These two countries are thus undergoing a true energy revolution from which the rest of the world can learn valuable lessons.

What is a negative electricity price?

This is a phenomenon that occurs when energy production far exceeds consumption. Electricity producers no longer know what to do with their surplus—so they’re willing to pay consumers to absorb it. In other words, electricity is so abundant that it has no market value at that precise moment.

Record figures in 2026

According to a report published on April 20, 2026, in PV Magazine, based on data from the analysis firm Montel, Spain recorded 397 hours of negative prices between January and March 2026—a figure well above the 48 hours recorded during the same period in 2015. Portugal recorded 222 hours of negative prices during the same period.

Why are Spain and Portugal particularly affected? Both of these countries have invested heavily in renewable energy in recent years. Spain, in particular, has developed massive solar farms in its sunniest regions—Andalusia, Extremadura, and Castile. As a result, on certain spring days with plenty of sunshine and low demand, solar power plants generate far more electricity than the country can consume.

What does this teach us about Gabon?

This European phenomenon illustrates a fundamental truth: Solar energy is an abundant source of energy when given the means to expand. Gabon, with its tropical sunshine—which far exceeds that of Spain—has even greater potential.

The difference is that Gabon does not yet have a surplus problem—on the contrary, millions of Gabonese still lack reliable electricity. That is exactly why every installation WOW2000 account. Our solar panels enable every Gabonese family and business to generate its own energy—clean, free, and inexhaustible.

Battery storage: the key to preventing waste. In Spain, excess energy is often wasted due to a lack of sufficient storage capacity. That is why WOW2000 always recommends pairing your panels with a lithium battery — to store every watt generated and use it when you need it.
