Preparatory work is now ongoing for a geothermal exploration drilling campaign in Grenada with target locations around Mount Saint Catherine.
Key preparatory work has been completed for an expanded geothermal drilling campaign in Grenada that aims to determine the viability of geothermal power generation. The plan is now to drill wider wells using directional drilling technology instead of the originally planned slim hole wells. With the upgraded drilling scope, the project timeline has now extended to 2028.
Geothermal drilling will be done at Mount St. Catherine, in the north of the island. Previously announced drilling plans have indicated prospective locations at Plaisance, St. John and Tricolar, St. Patrick, though it is unclear if these are the same locations being targeted under the current strategy.
The project is designed to provide the Government of Grenada with the technical evidence required to determine whether to proceed with the development of a geothermal power plant. Subject to favourable results, the next phase is expected to involve a competitive tender process to attract private sector investment for construction and operation.
“The results of this drilling phase will determine geothermal energy’s role in Grenada’s long-term energy future,” said Prime Minister of Grenada, Hon. Dickon Mitchell.
“We are committed to the pursuit of local pathways to energy security, reduced dependence on imported fuels, and enhanced economic opportunities for our people.”
So far, a dedicated Project Management Unit has been established to oversee the drilling campaign. The environmental and social impact assessments, as well as land acquisition, have been completed. Engineering designs and procurement are also at an advanced stage, with technical support provided by the Government of New Zealand.
The new phase is backed by a GBP 10 million contribution from the UK’s Foreign, Commonwealth & Development Office (FCDO) made in 2025. It builds on the Caribbean Development Bank’s earlier approval of USD 9.4 million in 2023 for the Grenada Geothermal Drilling Project, with financial support from partners including the Inter-American Development Bank, the Global Environment Facility, the European Union, and the Government of Italy.
