One of the Caribbean’s most anticipated clean energy development projects has reached a pivotal turning point, as the Nevis Geothermal Project wraps up the final major pre-mobilization milestone: a full independent inspection of its custom drilling rig taking place at an Icelandic facility.
The update was shared by Nevis Premier and Nevis Island Administration (NIA) Energy Minister Mark Brantley during his monthly press briefing on August 25, one day ahead of the official project announcement. Brantley confirmed that the rig inspection, being held from August 24 to 28 at the Iceland Drilling Company’s operations site, is the last required step before the heavy equipment can be shipped to the Caribbean island.
“The final pre-condition for mobilization of the drill rig to Nevis is an inspection of that drill rig, and that inspection is currently underway in Iceland,” Brantley told reporters.
The third-party assessment is being carried out by Scotia Drilling Consultants, a United Kingdom-based firm with specialized expertise in drilling rig safety and performance verification. Inspectors are conducting thorough reviews of the Drillmec HH-300 “Týr” rig’s structural integrity, mechanical systems, operational functionality, and core safety protocols. To oversee the inspection process and coordinate with international geothermal and engineering specialists, Nevis Electricity Company Limited (NEVLEC) General Manager Nelson Ald Stapleton and Project Coordinator Naftalie Errar have traveled to Iceland to be on-site for the assessment.
Once the inspection is completed and passed, Brantley noted, all preliminary requirements will be fulfilled to advance the project to its next critical phase: transporting the 272-metric-tonne drilling rig to Nevis. The massive rig is slated to drill five exploratory and production geothermal wells at the project’s Hamilton site, located on Nevis’ northern coast.
While international teams wrap up the rig inspection in Iceland, on-the-ground preparations have already begun at the Hamilton site in Nevis to welcome the equipment and prepare for drilling to start. Brantley confirmed that soil testing and pre-construction technical assessments launched the same week as the inspection, laying the groundwork for the well pad — the reinforced concrete foundation that will support the heavy drill rig during operations. Civil construction work for the well pad will be completed by Icelandic engineering firm COWI, with project supervision provided by Iceland Drilling, Brantley added.
The development of the geothermal wells is the core component of the broader Nevis Geothermal Project, a long-planned initiative designed to unlock Nevis’ abundant underground geothermal reserves for utility-scale electricity generation. The end goal is the construction of a 30-megawatt geothermal power plant that will produce zero-emission, renewable baseload electricity for the entire Federation of St. Kitts and Nevis. Once operational, the plant is expected to drastically cut the country’s reliance on costly, carbon-intensive imported fossil fuels, while significantly strengthening the nation’s long-term energy security.
The project is led by the NIA, with NEVLEC acting as the main executing agency, and receives full backing from the Federal Government of St. Kitts and Nevis. Brantley disclosed that the NIA has already disbursed approximately US$6 million to Iceland Drilling to keep project preparations moving forward on schedule.
Beyond benefiting St. Kitts and Nevis, Brantley highlighted that the project has drawn growing interest from neighboring Caribbean nations, signaling its potential to reshape regional clean energy access. He confirmed that the leader of Sint Maarten will visit Nevis in the coming weeks to hold discussions about the island’s geothermal development, including the possibility of Sint Maarten importing carbon-free electricity generated from Nevis’ geothermal resources in the future.
Brantley closed his briefing by expressing gratitude to all stakeholders involved in advancing the project, specifically recognizing NEVLEC, Stapleton, and Scotia Drilling Consultants for their work and technical expertise during the inspection phase. He also reaffirmed the critical role of the partnership between the NIA and the federal government in moving the project toward full commercial operation, extending public thanks to Prime Minister Terrance Drew for his continued collaboration.
“I never speak about this project without referencing the participation of the Federal Government and to say again my gratitude to Prime Minister Hon. Dr. Terrance Drew for his partnership on seeking to bring this particular project to commercialization for the benefit of all the people of St. Kitts and Nevis,” Brantley said.
