Dominica’s Geothermal Features

Dominica’s Geothermal Features have enabled the construction of a Geothermal Power Plant. The Island’s geothermal features are vital to its natural landscape and contribute to its unique ecological and geological characteristics. They are primarily concentrated in the Roseau Valley, known for its significant geothermal activity.

Key Geothermal Sites

• Boiling Lake: One of the most prominent geothermal features, the Boiling Lake is the second-largest hot spring in the world. Located in the Valley of Desolation within Morne Trois Pitons National Park, the lake’s water temperature near the edges ranges between 82-92°C and is constantly boiling due to volcanic activity beneath.
• Valley of Desolation: This area is characterized by its steaming vents, boiling mud pools, and colourful mineral deposits, providing a stark contrast to the lush vegetation found elsewhere in the park. The Valley of Desolation is a dramatic display of ongoing volcanic processes.
• Titou Gorge: Known for its warm water heated by geothermal activity, Titou Gorge offers visitors a unique swimming experience through a series of natural “rooms” and ponds formed by high cliff walls​.

Geothermal Energy Development

Dominica has been actively developing its geothermal resources for over a decade, focusing on reducing its reliance on diesel-generated electricity. The island’s geothermal potential is estimated to exceed 500 MW, making it the largest in the Caribbean. The primary project in the Wotten Waven and Laudat areas aim to harness this energy to meet domestic needs and potentially export electricity to neighbouring islands such as Guadeloupe and Martinique.

Geothermal Energy Projects

The Dominica Geothermal Development Company (DGDC) has been at the forefront of developing geothermal energy on the island. The first phase involves the construction of a 7 MW geothermal power plant in Laudat, supported by various international partners, including the World Bank, UK’s DFID, and the Clean Technology Fund. This project aims to provide a stable and renewable source of electricity, reducing the island’s reliance on imported diesel.

Environmental and Economic Impact

Harnessing geothermal energy is expected to have significant environmental and economic benefits for Dominica. It will reduce greenhouse gas emissions, lower electricity costs, and promote energy security. Additionally, the development of geothermal resources is seen as a catalyst for economic growth, attracting investment and creating jobs in the renewable energy sector.

Dominica’s geothermal features highlight the island’s volcanic origins and represent a promising future in sustainable energy development. These initiatives underscore the island’s commitment to responsibly harnessing natural resources while preserving its unique ecological heritage.
