Romania could fully shut its sole Cernavodă nuclear plant as Danube cooling water drops, threatening power supply, Nuclearelectrica stock, and the Romanian leu.
Nuclearelectrica (SNN) operates the Cernavodă plant, which faces shutdown due to critically low Danube water levels used for cooling. The closure halts its revenue-generating operations, directly hitting earnings. The article reports the imminent risk, triggering a sell-off in SNN shares.
The Cernavodă plant has two reactors totaling about 1,300 MW. A full shutdown would eliminate all output, which accounts for roughly 100% of SNN's electricity generation revenue.
After a sharp drop, key support levels on the Bucharest Stock Exchange include the 200-day moving average and prior support from Q3 2025 lows.
The shutdown of Romania's primary nuclear plant is likely to increase demand for imported energy, widening the current account deficit and putting depreciation pressure on the leu. The article underscores a sudden negative supply shock for the economy. Markets may sell RON, pushing EUR/RON higher.
EUR/RON trades in a managed float around 4.95-5.00. A break above 5.05 could signal strong depreciation pressure.
It raises the cost of energy imports, potentially widening the trade deficit and reducing foreign confidence, leading to leu selling against the euro.
The BET index includes Nuclearelectrica (SNN) as a significant component. As SNN shares sell off on news of the nuclear plant shutdown, the index faces downside pressure. The article highlights systemic risk to Romania's energy sector, dampening investor sentiment broadly.
Nuclearelectrica typically represents around 10-15% of the BET index. Its decline can materially move the index.
Analyst valuations remain mixed; however, the shutdown risk introduces heightened uncertainty that could compress P/E multiples across Romanian equities.
Romania's Cernavodă nuclear plant, which supplies about 20% of the country's electricity, faces shutdown within days due to critically low water levels on the Danube used for cooling. The closure would force Romania to import power or ramp up fossil fuel generation, straining the energy grid and pressuring the leu. Nuclearelectrica shares (SNN) tumbled on the news, dragging the Bucharest index lower.
Low water levels in the Danube River, which provides cooling water for the Cernavodă plant, have dropped below the minimum required for safe operations, forcing a potential shutdown within days.
The Cernavodă plant supplies about 20% of the country's electricity.
The shutdown pressures Romania's energy independence, could raise electricity prices, weaken the leu, and increase reliance on imported natural gas or power.
