PT used to be very energy dependent due to not having much local fossil fuel. They had to import most of it. Simultaneously, they have a lot of sun, a lot of wind, and the tide. Also turns out it’s warm so they don’t need all that much power. So yeah, renewables are optimal for them in this specific scenario. That’s definitely a positive thing.

It’s good PR but I just find it relevant to point out that it’s not necessarily an “example” beyond that. But yeah, they are getting cheaper. They’re just particularly cheap for a country with great weather and wind with low consumption.
