Concentrated solar is still coming down in price and being built in China and its ability to store the energy until dusk made it a good choice anywhere that had bright sunshine even after PV got cheap.
At least until batteries got cheap too.
Now it's super niche.
Also, some quick calculations based on the average yearly generation and estimated PPA suggests that it generated electricity worth roughly the same amount as the big scary number in the headline.
Presumably the PPA was set up pay for the construction plus profit over some timescale. Paying it off after 10 years isn't great but it's not bad either.
