US-Ecuador Nuclear Energy Cooperation Agreement Signed — Civilian Power and Research

Agreement Framework

The United States and Ecuador signed a bilateral nuclear energy cooperation agreement (commonly known as a "123 Agreement" under US law) establishing the legal framework for civilian nuclear technology transfer, training, and project development. The agreement was published in Ecuador's Official Register following diplomatic exchanges in Washington.

Parameter	Detail
Agreement type	Bilateral nuclear energy cooperation (123 Agreement framework)
Parties	United States — Ecuador
Scope	Civilian nuclear power generation and research
Military/weapons	Explicitly excluded
Status	Signed; implementation framework pending
Legal basis (US)	Section 123 of the Atomic Energy Act of 1954

Energy Deficit Context

The agreement's timing is directly linked to Ecuador's structural energy crisis, which reached critical intensity in 2024:

Energy Metric	Value
Installed capacity	~8,800 MW
Hydroelectric share	~75%
Thermal share	~20%
Renewable (non-hydro)	~5%
Peak demand (2025)	~4,800 MW
2024 deficit	Up to 1,500 MW during drought
Estimated economic cost (2024)	$3-4 billion
Blackout hours (2024 peak)	Up to 14 hours/day in some provinces

Ecuador's ~75% dependence on hydroelectric generation makes the grid critically vulnerable to drought cycles, which are intensifying due to climate change and El Niño variability. The 2024 crisis — which saw rolling blackouts of up to 14 hours per day in some provinces — exposed the urgent need for baseload generation that does not depend on rainfall.

Nuclear Energy Potential

Nuclear energy represents a long-term diversification option for Ecuador's energy matrix, though deployment is realistically a 10-15 year horizon:

Nuclear Option	Capacity	Timeline	Estimated Cost
Small Modular Reactor (SMR)	50-300 MW per unit	2035-2040	$1-3 billion per unit
Research reactor	1-10 MW	2030-2033	$50-200 million
Full-scale conventional	1,000+ MW	2040+	$8-15 billion

Small Modular Reactors (SMRs) — the most likely near-term application — are being developed by several US companies including NuScale Power, TerraPower (Bill Gates-backed), and X-energy. SMRs offer several advantages for Ecuador's context:

• Scalable deployment — units of 50-300 MW match Ecuador's grid capacity
• Smaller footprint — suitable for geographic constraints
• Baseload reliability — operates independently of weather and hydrology
• Lower upfront capital — compared to conventional nuclear plants

Cooperation Components

The agreement is expected to cover multiple cooperation tracks:

Power Generation Track

• Feasibility studies for nuclear power plant siting
• Technology assessment and vendor selection support
• Regulatory framework development (nuclear safety authority)
• Grid integration analysis
• Workforce training and university programs

Research Track

• Medical isotope production for cancer treatment
• Agricultural applications (food irradiation, pest control)
• Materials science and industrial applications
• Academic partnerships with Ecuadorian universities
• Comisión Ecuatoriana de Energía Atómica (CEEA) capacity building

Strategic Partnership Context

The nuclear agreement slots into an expanding US-Ecuador strategic partnership that has deepened significantly under the Noboa administration:

Agreement	Date	Domain
Security cooperation	Ongoing since 2023	Counter-narcotics, military equipment, intelligence sharing
Reciprocal trade agreement	March 13, 2026	Tariff elimination, mineral exports, agriculture
Nuclear energy cooperation	March-April 2026	Civilian power and research
Mining cooperation	2025	Critical minerals supply chain (copper, lithium)

The US has strategic interest in Ecuador's nuclear pathway for several reasons:

• Counter Chinese influence — China's CGN and Russia's Rosatom have been expanding nuclear cooperation in Latin America (Argentina, Brazil, Bolivia)
• Critical minerals — nuclear cooperation strengthens the broader US-Ecuador minerals partnership, particularly around copper and rare earth supply chains
• Regional security — energy stability in Ecuador reduces migration pressure and strengthens a key allied government

Regional Comparison

Ecuador would be entering nuclear energy at a relatively early stage compared to regional peers:

Country	Nuclear Status	Capacity
Argentina	Operating (3 reactors)	1,641 MW
Brazil	Operating (2 reactors)	1,884 MW
Mexico	Operating (2 reactors)	1,552 MW
Chile	Research reactor only	N/A
Colombia	Research reactor only	N/A
Ecuador	No reactors; cooperation agreement signed	N/A

What to Watch

• Feasibility study commissioning — the first concrete deliverable under the agreement; US Department of Energy or national laboratory involvement (likely Idaho National Laboratory or Oak Ridge) would signal serious implementation intent
• Regulatory framework — Ecuador currently lacks a nuclear regulatory authority; establishing one is a prerequisite for any reactor deployment and will require legislative action in the National Assembly
• SMR vendor engagement — whether NuScale, TerraPower, or X-energy conduct preliminary site assessments in Ecuador; NuScale's recent certification by the US Nuclear Regulatory Commission makes it the frontrunner for export
• CEEA capacity — the Comisión Ecuatoriana de Energía Atómica's institutional capacity will need significant expansion; training pipelines with US universities will be an early indicator
• Financing structure — nuclear projects require sovereign-backed financing or multilateral guarantees; the US International Development Finance Corporation (DFC) and Export-Import Bank could play catalytic roles
• Political continuity — nuclear energy projects span multiple presidential terms; the agreement's durability will depend on whether it survives potential political transitions
