Transmission network is next for Dominica’s geothermal project

Dominica Geothermal Development Company is now welcoming proposals and bids for the next step in developing the country’s first geothermal plant.

The Dominica Geothermal Development Company (DGDC) has issued a call for Expressions of Interest (EOI) for work on developing the transmission network in line with the geothermal project in Roseau Valley, Dominica, ThinkGeoEnergy reported.

Contractors are needed for the design, supply, and installation of four substations, and the “design, supply, and installation of new 69 kV overhead, 33 kV underground, and 11 kV transmission lines connecting DGPP to the existing Fond Cole switching substation.”

The World Bank funds a part of the geothermal project, and procurement of contracts will be determined via the World Bank’s standards on Procurement Regulations.

All interested companies are encouraged to contact DGDC through Rita Destouches-Edmund, Finance and HR Manager, at

Aside from the World Bank, Dominica’s Citizenship by Investment (CBI) Programme also funds the geothermal project.

The CBI programme has been essential in building back a better Dominica post-Typhoon Erika and Hurricane Maria, with thousands of climate-resilient residential buildings and other important infrastructure built in partnership with MMC Development Ltd., a private developing company that has been working closely with the government for several years. MMC Development Ltd. is also the company in charge of developing the country’s ambitious international airport.

DGDC has also reported the successful testing of RV-P2, the geothermal plant’s second well, and a proposal to develop an industrial-scale green hydrogen complex is already in the works.

Dominica’s geothermal plant is estimated to be completed in 18 months, with 23,000 houses expected to benefit from the renewable energy.

The size of the project is between 20MW to 250MW with a potential to expand. With an expected production of 27,000t to 30,000t per year of green hydrogen and 150t to 160t per year of green ammonia, the plant also aims to cater to international market.
