This city generates electricity for the entire
region and is therefore known as "the city of energy". When
saltpeter exportation in Chile was at its highest point, Tocopilla was especially significant as an export point. Nowadays, even when the saltpeter is not so profitable, Tocopilla is still home of companies focused on its extraction. Its position along the coast allows it to have an active fishing activity, that along with the mining activity are the main resources. It is a fishing port, with
fishmeal and canned fish factories. Through its port the copper from
Chuquicamata and saltpeter from El Toco are exported. Tocopilla has
metallurgic,
chemical and nitrate treatment industries, along with the former 276 MW
coal power plant. A 660 MWh
grid battery was built at the site in 2025. Due to these activities, Tocopilla is a
dormitory city, since many people work outside the city. Two other important sports are volleyball, with relative success at school and federated level. == In media ==
