Exploring Dominica’s Geothermal Resources

Exploring Dominica’s Geothermal Resources reveals the island’s immense potential for sustainable energy production. Dominica, often called the Nature Island of the Caribbean, sits within the Lesser Antilles Volcanic Arc, making it one of the most geothermally active locations in the region. Scientific assessments suggest the island has the capacity to generate at least 120 megawatts (MW) of geothermal electricity—far exceeding its current energy demands. This abundant resource positions Dominica as a regional leader in renewable energy, with the potential to achieve energy independence and export electricity to neighboring Caribbean nations such as Guadeloupe and Martinique.
Geothermal Resources Exploration and Early Studies
Interest in Dominica’s geothermal potential dates back several decades. Studies conducted in the Wotten Waven Geothermal Resource Area under the Interreg III B Program of the European Union in 2008 confirmed the high-temperature geothermal reservoir in the Roseau Valley. This led to exploratory drilling efforts, further solidifying the feasibility of large-scale geothermal energy production.
Recognizing the importance of this resource, the Dominica Governmentlaunched comprehensive surveys to assess the viability of harnessing geothermal energy for national consumption and potential export.
Dominica Geothermal Development Company (DGDC)
In December 2016, the Dominica Geothermal Development Company (DGDC) Ltd. was established to spearhead the island’s geothermal initiatives. This state-owned entity is responsible for managing all aspects of geothermal exploration, development, and implementation. Its primary mission is to increase the use of renewable energy in Dominica, thereby providing cheaper and more reliable electricity to its citizens while reducing dependence on imported fossil fuels.
The Laudat Geothermal Power Plant
One of the most significant milestones in Dominica’s geothermal energy journey is the development of a 10-megawatt (MW) geothermal power plant in Laudat, a village in the Roseau Valley. This project, currently in its construction phase, aims to:
- Reduce electricity costs for residents and businesses.
- Lower carbon emissions by replacing diesel-based power generation.
- Improve energy security and independence by tapping into a locally available, renewable energy source.
The power plant will generate enough energy to supply approximately 23,000 homes, contributing to Dominica’s goal of becoming the world’s first-climate resilient nation.
Financial Backing and International Partnerships
The Dominica Geothermal Development Project has attracted substantial financial and technical support from several international organizations:
- Caribbean Development Bank (CDB) – Approved a USD 34.8 million loan in December 2024 to finance the plant’s construction.
- European Union Latin America Investment Facility (LACIF) – Provided EUR 2 million in technical assistance for exploratory drilling and feasibility studies.
- Ormat Technologies Inc. – Signed an agreement in December 2023 to finance, construct, and operate the Laudat geothermal plant for 25 years before transferring ownership to the Government of Dominica.
These collaborations ensure the successful implementation of the project, positioning Dominica as a leader in Caribbean renewable energy.
Environmental and Economic Impact on Dominica
Harnessing geothermal energy provides significant benefits to Dominica:
- Carbon Reduction – Replacing fossil fuels with geothermal power will significantly reduce greenhouse gas emissions.
- Lower Electricity Bills – Renewable energy production will drive down energy costs, benefiting businesses and consumers.
- Job Creation – The project has already created employment opportunities in construction, engineering, and maintenance.
Challenges and Future Outlook
Despite the promising developments, Dominica’s geothermal sector faces challenges such as:
- Technical difficulties related to deep drilling in volcanic terrain.
- Environmental concerns related to the impact on local ecosystems.
- High initial costs of infrastructure development.
However, with ongoing government support and international investment, Dominica remains on track to become a regional renewable energy hub. Future plans include expanding geothermal capacity and developing an undersea cable to export electricity to nearby islands.
Dominica’s Geothermal Future
Exploring Dominica’s geothermal resources has unlocked a pathway to sustainable energy, economic growth, and environmental resilience. With continued commitment to renewable energy development, Dominica is well-positioned to lead the Caribbean in green energy transformation, ensuring a cleaner, more sustainable future for its citizens and the region.
