Comment on Renewables supply 71% of Portugal’s electricity in 2024, led by solar

I am talking about feed-in from home users, which would work largely without storage if it was allowed to feed the excess into the grid during the day (like it is posdible in most other EU countries).

But due to bureocratic hurdles this is basically not allowed in Portugal and the thus required in-home batteries are largely unaffordable by the relatively low income households here.

I think that was the case before but changed last year. I know people who sell the excess during the day. Not sure if you are from Portugal but here is a link in Portuguese adene.pt/venda-do-excedente-no-autoconsumo-simpli…

  Thanks for the link. I’ll have a closer look at this.

Where is even coming from when there is no sun?

  No sun in Portugal? Maybe in rainy Porto.

    There are those things called nights, clouds and shorter winter days 🤷‍♂️

    There is also such things as other power sources and demand variations 🤷‍♂️ Very few people run their electric stoves at 2am.
    
    Look, this is not rocket science. It works well in other EU countries. No one claimed that PV could cover 100% of the electricity demand without storage.

    Portugal has a huge installed base of hydro-generation, some of which is capable of being used to store excess energy (by pumping it up to the upper basin of the dam for later use in generation).
    
    The mix of lots of hours of sunlight, the country being not so hot that solar panels suffer from lower efficiency due to heat and hydro-generation which can be used for storing excess power produced for use later, makes the country pretty much optimal for solar generation.
    
    No, the reason for the crap legislation can probably be found in the deep incestuous relationship between the two main political parties and the largest power generation company of the country alongside Portugal being one of the most corrupt countries in the EU.

  Portugal is so sunny that Lisbon is literally the city of Europe with the most hours of sunlight per year.
