Nuclear expansion execution risk: Dukovany project faces potential cost overruns (reference Olkiluoto, Flamanville delays), construction timeline slippage beyond 2036 target COD, and vendor technology risk if selecting unproven SMR designs versus proven PWR technology
Coal asset stranding: 4+ GW coal fleet faces accelerated retirement pressure from EU carbon pricing (€80-100/tonne by 2030 estimates) and tightening emissions standards, requiring write-downs and replacement capacity investments while losing dispatchable backup for renewables
Renewable integration challenges: Adding 3+ GW intermittent solar/wind without adequate storage or grid flexibility creates curtailment risk, negative pricing exposure during high-generation periods, and potential grid stability issues requiring costly ancillary services
Decentralized generation erosion: Rooftop solar adoption and corporate PPAs with independent renewable developers bypass ČEZ's distribution network and reduce retail customer base, particularly in commercial segment where self-generation economics improve
Cross-border competition: German and Polish utilities expanding into Czech market with competitive retail offers and renewable development, pressuring market share in liberalized segments outside distribution monopoly
Nuclear decommissioning liabilities: €4-5 billion present value of future decommissioning costs for existing reactors creates long-tail obligation, with funding adequacy dependent on investment returns in segregated funds
Capital intensity of transition: €15+ billion investment program through 2030 (nuclear, renewables, grid) strains free cash flow, potentially forcing dividend cuts from current 60-80% payout or equity dilution if debt capacity exhausted
