• [ ] I have tested my parser changes locally with poetry run test_parser "zone_key"

By the way, one of the reasons I opened https://github.com/electricitymaps/electricitymaps-contrib/issues/2883 is IIRC that the current source for Bolivia originally didn't separate wind from solar and lumped biomass with thermal. I'm not sure if there's still some biomass included with thermal (biogas perhaps? Or I'm making it up), but with the more extensive data now also offered by the current source, the main advantage would be the ability to distinguish between the various types of thermal generation. The IEA says Bolivian thermal generation is almost entirely natural gas, though.

Edit: the price data is also interesting

@Nil-Cipher, do you remember what's missing from making this ready for review? We'd like to either get it done and merged, or close the PR for now :)
