Electricity customers across Dominica are seeing lower power bills for July 2026 as geothermal energy begins delivering tangible savings through a reduced fuel surcharge, according to Dominica Electricity Services Ltd. (DOMLEC).
The utility said in a Facebook post that customers in every billing category should notice a reduction in their July bills, provided their electricity consumption has not changed significantly. The savings follow the integration of geothermal energy into Dominica’s electricity generation mix, which has lowered the fuel surcharge applied to customers’ bills.
According to DOMLEC, domestic customers using 100 kilowatt-hours (kWh) of electricity are expected to save about $24, while those consuming 250 kWh should see savings of approximately $61. Commercial customers using 500 kWh are expected to save around $122, while a business consuming 2,416 kWh could save about $589.
Larger consumers are also expected to benefit. Hotels using 8,609 kWh could see bill reductions of about $2,098, while industrial customers consuming 14,402 kWh are projected to save approximately $3,509.
DOMLEC said the examples represent savings of between 17 and 18 percent compared with what customers would have paid had geothermal energy not been available.
The company described the reduced fuel surcharge as another step toward a cleaner, more reliable and more secure energy future for Dominica, noting that renewable sources now account for approximately 68 percent of the country’s electricity generation. That progress, it said, moves the island closer to its national goal of achieving 100 percent renewable electricity generation by 2030.
DOMLEC thanked the Government of Dominica, through the Dominica Geothermal Development Company (DGDC), for its investment in the geothermal project, describing it as transformational for the country’s energy sector.
The utility also highlighted Dominica’s commissioning of the 10-megawatt geothermal power plant in 2026 as a major milestone in the country’s renewable energy transition. In the cover story of the June 2026 edition of CARILEC’s CE Industry Journal, DOMLEC Chief Executive Officer Dwayne Cenac and DGDC Chief Executive Officer Fred John said Dominica has become the first independent Caribbean nation to integrate geothermal energy into its national electricity grid, positioning the country as a regional leader in renewable energy development.
According to the article, the geothermal facility was developed by the DGDC with support from the Government of Dominica and international development partners and is expected to significantly reduce the country’s dependence on imported diesel fuel. Together with hydroelectric generation, geothermal energy is projected to supply about 60 percent of Dominica’s electricity needs, strengthening energy security while helping to stabilize electricity costs for consumers.
Cenac and John explained that DOMLEC is responsible for managing and operating the transmission infrastructure linking the geothermal plant, the island’s hydroelectric stations and the national electricity grid. They noted that the system is supported by a 6-megawatt/6-megawatt-hour Battery Energy Storage System, which enhances grid stability, improves resilience and allows for greater integration of renewable energy sources.
The article further noted that the geothermal project delivers benefits beyond lower electricity bills. It is expected to improve Dominica’s energy independence, reduce greenhouse gas emissions, enhance resilience against volatile global fuel prices and create new opportunities for economic growth and investment, while advancing the country’s vision of achieving 100 percent renewable electricity generation and building a more sustainable future for generations to come.
