Several mainstream media outlets in Europe have speculated that solar energy may have caused the massive blackout in Spain on April 28, but Spanish Prime Minister Pedro
Since he took power in 2018, energy developers have built solar parks, proved that power generation had attractive returns and pulled in capital from yield-hungry investors.
Last week, the Spanish government and Spanish grid operator Red Electrica released lengthy reports on the blackout that affected the Iberian Peninsula on April 28, 2025,
Immediately after, virtually all of Spain''s electricity generation tripped offline. One of the theories floating around is that things went wrong because the grid diverged from its normal...
REE [the Spanish grid operator] said it had identified two incidents of power generation loss, probably from solar plants, in Spain''s southwest that caused instability in the
Spain is one of the first countries to deploy large-scale solar photovoltaics, and is the world leader in concentrated solar power (CSP) production. Spain is also one of the European countries
At 12.33 pm, the Spanish power grid experienced a loss of generation in the south-west of the country. Most likely, these were solar power plants, but the operator is not sure yet.

At exactly 12:33:30, a cascading failure disconnected the grids of Spain and Portugal from the wider European electricity system, plunging millions into darkness. We now
By analysing minute-by minute data, we can pinpoint the moment where it all went wrong for Spain''s power grid.
At 12.33 pm, the Spanish power grid experienced a loss of generation in the south-west of the country. Most likely, these were solar power plants, but the operator is not sure yet.

The operator presented the following course of events. At 12.33 pm, the Spanish power grid experienced a loss of generation in the south-west of the country. Most likely, these were solar power plants, but the operator is not sure yet. Indeed, most of Spain's solar generation is located in the south-west of the country.

This situation had been repeated throughout the month, as in Spain the combined capacity of solar and wind energy can, given the right conditions, cover the country’s entire electricity demand during the brightest hours in the middle of the day.
Since 2010, Spain has been the world's leader in concentrated solar power (CSP). Spain is leapfrogged by Italy during 2011 following a later solar boom there to lose its position as the world's second largest installer of solar PV.
But due to oversights or overconfidence, they say Spain has not adapted to its reliance on solar energy. Prices and demand are too low. Its grid and use of battery storage are behind the times. In a country that is a test case for renewables, the solar boom appears to have gone too far, too fast.
In 2008 the Spanish government committed to achieving a target of 12% of primary energy from renewable energy by 2010 and by 2020 expected the installed solar generating capacity of 10 GW. Since 2010, Spain has been the world's leader in concentrated solar power (CSP).
