Geothermal Plant Clears Final Reliability Test, Commercial Operations Near

A significant milestone has been reached in Dominica’s journey toward cleaner and more sustainable electricity generation.

The country’s geothermal power plant has successfully completed its reliability testing, clearing one of the final technical requirements before entering commercial operation. According to the Independent Regulatory Commission (IRC), this long-awaited achievement means the Commercial Operation Date (COD) is expected to be reached very soon, potentially before the end of July 2026.

Executive Director Justinn Kase described the successful completion of the reliability test as encouraging news for the country’s electricity sector. Reliability testing is designed to confirm that a generating facility can operate consistently and safely over an extended period before it officially begins supplying electricity under commercial arrangements.

Once commercial operation begins, the geothermal plant will start supplying electricity under the agreed Power Purchase Agreement (PPA), allowing the contracted tariff for geothermal energy to take effect. This marks the transition from project development and testing to regular electricity generation as part of Dominica’s national energy mix.

For the IRC, however, commercial operation is not the end of the process. Kase explained that the Commission will closely monitor the performance of the geothermal facility during its first three months of operation, paying particular attention to how the introduction of geothermal generation affects electricity costs for consumers.

That monitoring exercise will provide valuable information on the practical impact of the project once electricity is being supplied under normal operating conditions. Rather than relying on projections alone, the Commission intends to assess actual performance and examine how the new source of generation influences customer bills over time.

The successful completion of reliability testing represents years of planning, engineering, construction and technical evaluation. As Dominica prepares for commercial geothermal generation, the project moves from promise to implementation, opening a new chapter in the country’s transition toward renewable energy.

The IRC says it will continue providing updates as commercial operation begins and as its monitoring programme progresses, ensuring consumers remain informed about developments within the electricity sector and their potential impact on the cost of power.
