For Jamaica, SMRs are merely opportunistic Nuclear Imaginings Untethered from Geography and Electrical Reality

There is a curious phenomenon that periodically appears in Jamaican public policy.

A difficult national problem emerges. The hard work of institutional reform, technical competence, disciplined maintenance, and long-term planning remains unfinished. Yet instead of addressing those fundamentals, influential voices become captivated by a grand technological solution promising to leapfrog reality.

The latest manifestation is the renewed enthusiasm for Small Modular Reactors (SMRs). The proposition is presented as visionary. It is marketed as modern. It is wrapped in the language of innovation, energy security, and economic transformation.

Yet when examined through the lenses of engineering, geography, economics, and operational reality, the SMR proposition for Jamaica begins to resemble something quite different: opportunistic nuclear imagining.

The June 5 island-wide blackout should have made this immediately obvious. That event was not fundamentally about inadequate generation capacity. Jamaica did not suddenly run out of fuel. Nor did the country suffer from an inability to produce electricity.

Instead, the blackout exposed deep vulnerabilities within a highly interconnected system. Transmission infrastructure, protection systems, control mechanisms, operational procedures, redundancy, recovery capability, and institutional resilience all came under scrutiny. Those are precisely the attributes that would need to function at exceptionally high levels if Jamaica were to operate a nuclear facility safely and economically.

The electrical grid, let alone a nuclear power plant, does not respond to speeches. It responds to engineering. It responds to highly trained operators, disciplined maintenance regimes, robust backup systems, sophisticated emergency planning, and institutions capable of performing consistently twenty-four hours a day, seven days a week, year after year.

Nuclear technology does not forgive mediocrity. That reality alone should inject a measure of humility into the current conversation.

Yet the problem runs much deeper. The SMR proposition is increasingly detached from Jamaica’s geographical and infrastructural scale.

Nuclear power emerged in large continental economies characterized by vast electrical systems, extensive industrial demand, significant engineering workforces, and massive populations over which multi-billion-dollar costs could be distributed. Jamaica possesses none of these characteristics. We are a small island developing state of fewer than three million people operating an entirely isolated electrical grid.

Proponents argue that SMRs are explicitly designed for smaller footprints, scaling down to outputs between 50 and 300 megawatts (MW). But this argument crumbles under basic electrical engineering realities.

Jamaica’s peak system demand typically hovers around a mere 600 to 650 MW. In an isolated grid, no single generating unit should exceed 10% to 15% of total system demand. If a single 150 MW or 300 MW nuclear unit trips unexpectedly—as units inevitably do—the sudden drop would instantaneously destabilize the entire network. Because we have no neighboring continental grid capable of absorbing sudden surpluses or providing large-scale wheeling support during major disturbances, the introduction of a standard SMR would create a persistent, systemic risk of catastrophic grid collapse.

Furthermore, the economic case demonstrating that SMRs would outperform rapidly advancing renewable alternatives combined with modern storage is non-existent. While international data shows utility-scale solar and wind costs continuing to plummet globally, the international evidence for nuclear capital flight points in the opposite direction.

What exists today is not a mature, globally demonstrated industry delivering electricity at scale and competitive prices. What exists is a collection of ambitious proposals, delayed pilot projects, and highly optimistic forecasts.

Consider the global bellwether for commercial SMR development: the NuScale Power project in Utah, USA. Before its outright cancellation due to a lack of utility buyers, estimated target prices for its power skyrocketed by over 50%, climbing to an astronomical $89 per megawatt-hour (MWh), even after factoring in billions in US government subsidies. For a nation like Jamaica, lacking established domestic nuclear supply chains, a nuclear regulatory ecosystem, or an existing workforce experienced in commercial radiation operations, our real-world levelized cost of electricity (LCOE) for nuclear would be prohibitively higher.

Jamaica should not be asked to become an experimental proving ground for unproven technologies still struggling to establish commercial viability in much larger and wealthier nations. There is no practical, costed domestic solution for long-term spent fuel management, nor is there a balance sheet in our public utilities capable of absorbing the inevitable multi-year construction cost overruns typical of nuclear projects.

Nor should policymakers overlook another inconvenient geographical fact. Jamaica sits within a highly seismically active region influenced by major fault systems, including the Enriquillo–Plantain Garden Fault Zone. Earthquakes are not theoretical possibilities in our part of the world; they are historical realities. Likewise, Category 4 and 5 hurricanes are not occasional anomalies; they are recurring features of Caribbean life.

Any serious discussion of nuclear deployment must therefore contend not merely with reactor containment design, but with the staggering costs of specialised seismic reinforcement, robust evacuation planning across constrained island corridors, emergency response capacity, hardened communications resilience, sovereign security requirements, and unprecedented insurance premiums. These are not peripheral issues. They are central, cost-heavy liabilities.

Yet the public discussion often proceeds as though the installation of an SMR would somehow solve Jamaica’s energy challenges by itself. It would not.

A reactor cannot compensate for weak institutions. It cannot repair fragile governance. It cannot substitute for a rigorous engineering culture. It cannot create operational discipline where such discipline does not already exist. It cannot magically transform a vulnerable transmission grid into a resilient one. In fact, the opposite is true: introducing a highly complex, brittle nuclear asset into an electrical ecosystem still struggling with basic transmission resilience would sharply increase systemic vulnerability rather than reduce it.

There is a more practical, proven path forward. Jamaica possesses abundant solar resources and significant wind potential. We possess clear, quantifiable opportunities for biomass, biogas, mini-hydroelectric systems, distributed generation, and modern utility-scale storage technologies.

For decades, Jamaican innovators demonstrated the genuine possibilities of renewable energy systems rooted in local realities rather than imported fantasies. The pioneering work of ENERPLAN and Verde Siempre explored biomass, biogas, agro-energy systems, and integrated renewable solutions long before sustainability became a fashionable buzzword. Their achievements earned international recognition, including a coveted Rockefeller Foundation award for innovation in underutilized renewable resources.

Those efforts were not exercises in abstract imagination. They were grounded in Jamaican geography, Jamaican agriculture, Jamaican engineering, and Jamaican realities.

That distinction is crucial. The future belongs not to whatever technology sounds most impressive at international conferences or generates the most glossy headlines. The future belongs to technologies that are technically appropriate, economically viable, operationally manageable, and geographically sensible.

Jamaica does not need energy fantasies. It needs energy resilience.

The lesson of June 5 is therefore not that Jamaica requires a nuclear reactor. The lesson is that Jamaica requires a stronger electrical network, stronger institutions, stronger technical capacity, and stronger operational discipline. Until those fundamentals are mastered, SMRs remain what they increasingly appear to be: not an energy strategy, but an opportunistic nuclear imagining untethered from geography and electrical reality.
