en.Wedoany.com Reported - Dominica Electricity Services Ltd. (DOMLEC) noted that although the geothermal power plant is still in commissioning, its power generation has begun to reduce the national electricity costs and diesel consumption. Against the backdrop of global fuel price fluctuations, this update plays a positive role in alleviating user dissatisfaction caused by power outages during commissioning.

The latest data shows that renewable energy now accounts for 51% of Dominica's energy consumption, with geothermal power contributing 26%. This has reduced the share of diesel power generation from 70% to 49%. Overall, despite rising fuel costs from January to April 2026, total electricity generation costs have declined.

As the commissioning of the geothermal power plant progresses, it is expected that more geothermal power will further reduce diesel usage. DOMLEC explained that electricity rates have been discounted during the commissioning period. When the Commercial Operations Date (COD) is announced, geothermal power will be sold at higher commercial rates, but even so, its cost remains far lower than that of the power mix without geothermal energy.

According to the latest update in April 2026, Dominica's 10 MW geothermal power plant has entered the final stage of commissioning. The development of this plant has gone through a long cycle, and its eventual transition to commercial operation is a positive signal for improving Dominica's energy security, while also providing a reference for similar projects in the Caribbean region.
