From Saint Lucia to Dominica, Nevis, Grenada and Jamaica, the region is moving from renewable-energy ambition toward infrastructure that could redefine energy security and disaster resilience.
For Caribbean nations accustomed to hurricanes, flooding, landslides and prolonged power disruptions, the transition to renewable energy is becoming about much more than cutting carbon emissions. It is increasingly about resilience.
Across the region, governments are looking beneath volcanic mountains, harnessing sunlight and wind, investing in battery storage and modernizing electricity networks in an effort to reduce dependence on imported fossil fuels.
The approaches differ, but the objective is increasingly shared: build energy systems capable of keeping Caribbean economies and communities functioning when the next major disruption arrives.
From geothermal exploration in Saint Lucia, Nevis and Grenada, to Dominica’s newly operational geothermal plant and Jamaica’s large-scale renewable-energy and battery-storage plans, the Caribbean’s energy transition is moving from policy aspiration into physical infrastructure.
The more important question, however, is whether these investments will translate into real resilience for Caribbean people.
LOOKING BENEATH THE SURFACE
Saint Lucia is testing whether the heat beneath its volcanic landscape can become part of the island’s energy future. The Government’s Renewable Energy Sector Development Project (RESDP) is designed to establish the viability of the country’s geothermal resource and create an enabling environment for future clean-energy investment.
Exploratory work focuses on Fond St. Jacques, Belle Plaine and Saltibus, with the programme involving three exploratory geothermal wells. The Government has also undertaken environmental and social assessment work and community consultations around the proposed activities.
For Saint Lucia, the attraction is straightforward.
A commercially viable geothermal resource could provide a source of locally generated, firm renewable electricity while reducing exposure to imported fossil-fuel prices. But exploration is only the beginning.
The drilling programme must establish whether the resource is sufficiently productive and commercially viable to support future electricity generation. That uncertainty makes the current phase particularly important: Saint Lucia is not yet celebrating geothermal power; it is gathering the evidence required to determine whether geothermal power can become a pillar of its energy system.
The process also demonstrates another principle central to a successful energy transition: communities must be part of the conversation.
WHEN RESILIENCE BECOMES INFRASTRUCTURE
Dominica perhaps offers the clearest example of the relationship between disaster experience and renewable-energy ambition. Hurricane Maria in 2017 devastated the island’s infrastructure and exposed the vulnerability of its electricity system.
Years of geothermal exploration followed, eventually leading to the development of a 10-megawatt geothermal power plant at Laudat. That project reached a historic milestone in July 2026, when commercial operations commenced. Ormat Technologies, the plant’s developer and operator under a 25-year power-purchase arrangement, confirmed the start of commercial operations in its 2026 second-quarter results.
The plant is designed to provide reliable, baseload renewable electricity to Dominica’s national grid.
The project is also connected to broader grid-strengthening efforts. World Bank project documentation details new and upgraded transmission infrastructure associated with evacuating the geothermal plant’s 10 MW output, including underground cabling.
That distinction is important.
A renewable generator is only as resilient as the infrastructure carrying its electricity.
Dominica’s experience therefore illustrates the broader lesson of the Caribbean energy transition: clean generation and resilient transmission must advance together.
FROM RESOURCE TO ENERGY INDEPENDENCE
Nevis is taking geothermal development to another stage. In May 2026, the Nevis Island Administration confirmed that a contract had been signed with Iceland Drilling for geothermal production-well drilling.
The programme calls for up to two production wells and one injection well, with the proposed geothermal plant expected to have a capacity of approximately 30 MW — more than the island’s current domestic electricity demand. Drilling is scheduled to begin in September 2026, with completion expected in the second half of 2027.
The potential significance is considerable for a small island. If the resource proves commercially viable, Nevis could move substantially closer to energy independence while creating an indigenous source of electricity.
But geothermal development carries significant exploration and financial risk. As Nevis Premier Mark Brantley has acknowledged, the drilling itself is the riskier stage because the success of the resource must first be demonstrated.
Nevis is therefore not yet at the finish line.
It is drilling toward the possibility of a different energy future.
DIVERSIFYING THE ENERGY MIX
Grenada is also pursuing geothermal resources while simultaneously exploring other renewable-energy technologies.
Government climate-planning documentation identifies Plaisance and Tricolor as geothermal development sites, with approximately 15 MW of geothermal potential identified and exploratory drilling planned.
But geothermal is only one part of Grenada’s strategy.
The country is also advancing a major solar-and-storage initiative at Maurice Bishop International Airport. Project documentation describes three solar plants with combined capacity of 15.1 MW, alongside a 10.6 MW / 21.2 MWh battery energy storage system and associated transmission and substation improvements.
This combination is significant. Geothermal can potentially provide firm generation, while solar can add daytime renewable production and batteries can store electricity for use when renewable output fluctuates.
Together, these technologies illustrate a broader regional shift toward diversified renewable-energy systems rather than dependence on a single technology.
BRINGING RENEWABLES TO SCALE
Jamaica demonstrates how the energy transition looks when applied across a much larger electricity system.
The country is pursuing a target of 50% renewable electricity generation by 2030. Its planning framework identifies wind, solar and battery energy storage as dominant resources in the preferred implementation pathway, alongside transmission upgrades needed to integrate substantially more variable renewable generation.
In 2026, Jamaica’s renewable-energy procurement ambitions expanded further, with the planned tender increasing to 300 MW of renewable generation paired with 150 MW of battery storage.
The storage component is particularly important.
Solar and wind output naturally fluctuates. Batteries can help absorb excess generation and return electricity to the system when renewable production falls or demand increases.
This is where Jamaica’s experience offers a lesson for the wider Caribbean:
The renewable-energy transition is also a grid-modernization challenge.
Installing solar panels and wind turbines is only part of the equation. Transmission systems, substations, storage, forecasting, regulation and consumer participation must evolve alongside generation.
THE REAL TEST: RESILIENCE FOR WHOM?
Across these countries, the technology and investment are encouraging. But technology alone does not equal resilience.
The ultimate test is what happens when a hurricane approaches.
Can a hospital maintain essential services?
Can an emergency shelter remain powered?
Can telecommunications continue operating?
Can water systems function?
Can businesses reopen faster?
And, perhaps most importantly, can ordinary households afford the electricity produced by the new energy system?
A Caribbean energy transition that reduces fossil-fuel dependence but leaves vulnerable households behind would be incomplete. Likewise, a country can install renewable generation and still experience widespread outages if its transmission and distribution infrastructure remains vulnerable to extreme weather.
Resilience therefore requires more than replacing diesel generation with geothermal or solar power.
It requires resilient energy ecosystems.
FIVE ISLANDS. DIFFERENT PATHS. ONE REGIONAL CHALLENGE.
The experiences of Saint Lucia, Dominica, Nevis, Grenada and Jamaica demonstrate that there is no single Caribbean pathway to renewable energy.
Saint Lucia is investigating whether geothermal resources can support future generation.
Dominica has crossed an important threshold, with its 10 MW geothermal plant now in commercial operation.
Nevis is preparing to drill production and injection wells for a proposed 30 MW geothermal facility.
Grenada is combining geothermal exploration with solar and battery storage.
Jamaica is pursuing renewable generation at utility scale while building the storage and grid capacity necessary to integrate it.
The technologies differ.
The scale differs.
The financing challenges differ.
Yet the strategic objective is increasingly the same:
greater energy security, reduced dependence on imported fossil fuels and stronger resilience against climate and economic shocks.
For Caribbean states, renewable energy is therefore no longer simply an environmental issue.
It is an economic issue.
It is an energy-security issue.
It is an infrastructure issue.
And increasingly, it is a disaster-preparedness issue.
The Caribbean has spent decades learning how vulnerable its infrastructure can become when a major storm strikes. The emerging renewable-energy transition offers an opportunity to change that equation.
The question now is whether governments, utilities, investors and communities can move quickly enough — and equitably enough — to ensure that the clean-energy future being built today is strong enough to withstand the storms of tomorrow.
