What moved
Record low river levels across Europe are forcing nuclear plants offline for cooling; power supply tightness is lifting European electricity and gas prices as thermal generation backstops.
The market transmission
Nuclear outages drive demand for substitution generation. Gas-fired plants are the marginal source across most of Europe, so thermal power shortages lift TTF prices directly. Electricity in turn lifts industrial input costs and inflation expectations. The supply tightness is near-term and structural while the heat persists, which is weeks.
What would change this
The tightness is real but not yet a supply emergency: Europe retains LNG import capacity and can draw on storage. The risk is not blackout but sustained price elevation in power and gas. Coal plants and hydro upside exist but coal is constrained by emissions policy and hydro by the same drought driving the nuclear crisis.
