Earth Venture Capital's Roadmap for De-Risking SMR Deployment in Southeast Asia sets out four overlapping phases across roughly five years: Foundational Design (Years 0–2), Institutional Mobilization (Years 1–2), Bankability & Market Structuring (Years 2–4), and Pilot Deployment (Years 3–5). The framework exists because SMR programmes in the region fail on sequencing more often than on ambition — governments routinely attempt financing structures before licensing pathways exist, or announce targets before regulatory capacity has been built.
Why sequence is the whole problem
Southeast Asia has no operating commercial nuclear plants today, and its governments are focused on securing overseas collaboration to de-risk first projects. Meanwhile the demand driver is not waiting: data centers are built in three to four years, while grid expansion and new generation take considerably longer.
The temptation under that pressure is to skip steps. It does not work.
Rully Hidayatullah of the ASEAN Centre for Energy identified the failure mode directly: "technology readiness alone will not determine SMR feasibility. It needs more than just technical know-how or innovative design but understanding the bigger picture and working together toward solutions that fit national needs and agenda."
This roadmap orders the work so that each phase creates the preconditions for the next.
Phase 1 — Foundational Design (Years 0–2)
Objective: establish the legal, technical and human basis for a nuclear programme before committing to any technology or site.
Engage the IAEA for legal and safety benchmarking.
Develop a vendor-neutral technology assessment framework.
Conduct siting, grid, waste and emergency planning studies.
Build domestic regulatory and workforce capacity.
Vendor neutrality deserves emphasis, because the pressure to abandon it arrives early and from well-resourced directions. A neutral assessment approach — not favouring one country's technology over another — is what ensures the selected SMR is genuinely the most suitable match for a specific national grid, and it materially strengthens the public-acceptance case later.
Domestic capability is the harder half of this phase.
Elina Charatsidou of KTH Royal Institute of Technology was unambiguous: "Southeast Asian countries can strengthen their nuclear capacity by working with experts from Europe or other experienced regions. Sustainable nuclear development requires not just imported technology, but also local know-how to manage and operate it independently. Without this foundation, even well-funded nuclear programs face significant risks and public resistance."
Thailand offers a working example, having begun strengthening nuclear-related education and workforce development through university programmes, research partnerships and technical training aligned with its long-term Power Development Plan.
Phase 2 — Institutional Mobilization (Years 1–2)
Objective: convert intent into published national commitments and testable regulatory processes.
Reactivate or update the national nuclear roadmap (as Vietnam did in late 2024).
Publish indicative SMR targets in the Power Development Plan or energy roadmap.
Launch regulatory pilots or sandbox licensing pathways (as Indonesia has via BRIN/BAPETEN initiatives).
Publication is the point. An indicative target in a national plan is what allows a developer to justify business-development spend and an investor to begin diligence. Without it, every conversation stays hypothetical.
Vietnam's trajectory illustrates the phase well: after an eight-year pause, it formally decided in late 2024 to resume nuclear power planning, including the previously shelved Ninh Thuận 1 and 2 projects, with policymakers explicitly stating that SMR technologies will also be evaluated as part of the longer-term energy mix. In June 2025, Prime Minister Phạm Minh Chính visited Blykalla's labs at KTH Royal Institute of Technology, calling on Swedish partners to collaborate on safe, clean, reliable nuclear solutions.
Vietnam's updated national energy resolutions also encourage private-sector participation in advanced energy technologies including SMRs. Notably, policymakers acknowledge the technology's early stage: given the lack of fully commercial reference projects globally, SMR-specific incentive mechanisms cannot yet be defined, and support mechanisms will be submitted to the National Assembly once commercial viability and suitability for Vietnamese conditions are demonstrated. That is a realistic posture, not a hesitant one.
Phase 3 — Bankability & Market Structuring (Years 2–4)
Objective: build the commercial and contractual machinery that makes a first project financeable.
Enable DPPA / private offtake for industrial and data center loads.
Define tariff structures recognising firm baseload value.
Clarify nuclear liability, licensing timelines and risk allocation.
Prepare standardized contracting frameworks.
This is where most programmes stall, because each item requires legislative or regulatory action rather than announcement. It is also the phase with the highest leverage on final electricity cost — small reductions in the weighted average cost of capital, through sovereign guarantees or DFI participation, move LCOE more than marginal CAPEX reductions do.
Tariff design carries particular weight. Matt Loszak of Aalo Atomics argues tariff structures should reward firm, high-availability power delivered behind the meter rather than forcing SMRs to compete on a merchant basis against intermittent renewables.
Fanny Widepalm of Blykalla adds an access point that is easy to overlook in drafting: "it is beneficial if the potential financing scheme is open to any actor, not only utilities – to enable advanced SMRs to access the financing."
Vietnam has already moved on the DPPA element, allowing electricity buyers in industrial parks, high-tech agricultural zones and commercial developments to contract power directly from generators, with prices negotiated bilaterally whether delivered via private lines or the national grid.
Standardized contracting is the quiet multiplier. Aalo Atomics emphasises standardized project documentation, a common term sheet across projects, and regional vendor-qualification programmes built on a "certify once, use everywhere" principle — reducing transaction friction, shortening negotiation cycles, and enabling replication across multiple provinces and markets.
Phase 4 — Pilot Deployment (Years 3–5)
Objective: get a first unit built under conditions that make the second one easier.
Secure Government Anchor Offtake to floor early demand.
Establish a National De-Risking / Blended Finance Fund (Singapore's model being the regional reference).
Prioritise co-location with AI-driven data centers.
Government anchor offtake solves a specific early-phase problem: while a data center campus is still ramping, unused capacity undermines project economics. A state utility absorbing excess supply provides a revenue floor, lowering the cost of capital and accelerating financial close.
On blended finance, Singapore's Green Investments Partnership — through which the Monetary Authority of Singapore raised US$510 million in 2025 for "marginally bankable" green infrastructure — is structurally instructive, though it is worth stating plainly that nuclear and SMRs are not currently listed as eligible sectors. The relevance is architectural: tiered risk tranching, public–private co-investment and long-term infrastructure financing are precisely what investors identify as necessary for SMR deployment. Andrew Wong of TRIREC noted that while Singapore is unlikely to host reactors given its risk appetite and safety considerations, it could serve as the financial architect of nuclear deployment in Southeast Asia.
Co-location with AI data centers closes the loop the roadmap opened. These are large, creditworthy customers capable of committing to the long-term offtake that multi-decade nuclear economics require — the anchor loads that make bankable first deployments possible.
The two things the SMR deployment roadmap Southeast Asia cannot schedule
Public trust does not have a phase. It runs across all four.
As Rully Hidayatullah put it: "Public engagement shall be continuous, from pre-licensing through construction, operation, and decommissioning… The community engagement shall be treated as an ongoing, foundational element, not a short-term PR effort."
There is proven practice to draw on.
Elina Charatsidou points to Sweden, where regulators and waste-management institutions — the Swedish Radiation Safety Authority and SKB — have maintained open communication on nuclear waste safety and storage: "Through consistent public engagement updates, Sweden has been able to gain public acceptance for geological repositories, a significant challenge many other countries are still facing."
Blykalla's Andreas Törnblom finds engagement most effective when technical concepts are explained in everyday language and connected to concrete community benefits — stable electricity prices, industrial investment, job creation. Aalo's US practice runs parallel: open houses with VR walk-throughs, on-site environmental kiosks displaying real-time radiation dose, water use and noise data, and formal mutual-aid agreements with local first responders.
Fleet economics do not arrive on schedule either — they arrive with volume. Blykalla's critical constraint is fuel: securing HALEU access and fabrication capacity only becomes economically viable when tied to a multi-unit fleet rather than a single first-of-a-kind plant. A roadmap that ends at one pilot has not finished the job. Cost competitiveness requires fleet-scale planning from the start.
Why Earth VC built this
Earth Venture Capital is a deep-tech venture firm investing in the science and engineering behind the climate transition. We have backed next-generation nuclear directly since 2024, with positions in Aalo Atomics (United States) and Blykalla (Sweden) — two of the most closely watched advanced reactor developers globally.
This roadmap synthesises 15 in-depth interviews with policymakers, regulators, investors, data center operators and SMR developers across Southeast Asia, alongside what we observe from the capital side of first-of-a-kind nuclear.
As our founding partners wrote in the report's foreword: "If Southeast Asia is to remain sovereign in the digital era, it must be powered by energy that is clean, abundant, and unwavering."
