The Romanian government announced on Saturday that it has approved a series of emergency measures to increase water levels in the River Danube. The move is intended to facilitate the cooling of the Cernavoda nuclear power plant, which has been forced to halt operations due to record-low river levels.
The Cernavoda facility, operated by state-owned Nuclearelectrica, provides a portion of Romania's electricity, but its second reactor was scheduled for shutdown after the first was previously closed due to water scarcity. The Romanian government declared a month-long state of emergency for August 2026 after a significant decline in national power production.
To address the shortage, the National Committee for Emergency Situations approved emergency dredging of the Danube near the power plant. Additionally, workers will construct a groyne—a rigid hydraulic structure—along the Old Danube channel to divert water toward the plant's cooling system intakes. High-capacity pumps will also be deployed to maintain necessary water levels if current conditions persist.
Beginning Saturday, the hydro plant operator Hidroelectrica started a five-day release of water from reservoirs located on the River Olt. This release is designed to supplement the flow of the Danube and generate additional electricity during the ongoing energy shortage.
For residents and businesses in Romania, the concrete day-to-day change is a heightened risk to energy stability during the state of emergency. While specific changes to monthly utility bills or immediate price hikes were not reported, the government's mobilization of high-capacity pumps and emergency construction highlights the urgency of maintaining the cooling systems required for nuclear safety and generation. These measures are expected to be active throughout the remainder of August, with the specific reservoir releases from the River Olt scheduled for a five-day period starting Saturday.
The situation sets a precedent for how climate-related river fluctuations can disrupt national energy security and necessitate multi-agency interventions involving nuclear, hydro, and emergency management sectors. The knock-on effects include the depletion of water reserves in the River Olt reservoirs to stabilize the Danube, potentially affecting future hydro-generation capacity. The next steps involve monitoring the effectiveness of the dredging and groyne construction, with the state of emergency currently set to last through the end of August 2026.
