Law 19,657 establishes regulatory frameworks for geothermal exploration and exploitation, as well as standards for concession allocation and tenders.
The Ministry of Energy is responsible for the application, control and enforcement of geothermal regulation frameworks and the management of auction and bidding processes. Public bidding for concession granting occurs every two to three years and is open to every Chilean person or corporate body organised under Chilean laws. The legislation regulates the relationships between the government and concession holders, landowners, mining properties or water exploitation rights when exploiting geothermal energy.
In order to attract international investment in the geothermal energy sector, the Chilean government has enhanced the financial incentives contained in Law 19,657.
