Romania is facing continued pressure on electricity supply costs as both Cernavoda nuclear units remain offline without a firm restart timetable. The situation is increasing reliance on hydro, thermal generation and renewables. Despite the nuclear outage, the electricity system has remained stable.
Hidroelectrica has increased production during peak-demand periods. Energy Complex Oltenia continues to supply power despite ageing equipment and technical constraints. Wind and solar generation have also contributed to covering the shortfall.
Grid balance and approvals for additional capacity
Transelectrica and the National Energy Dispatch Centre have maintained system balance. The regulator ANRE has accelerated final approvals for additional generating capacity. These measures have supported continued stability in the power system.
Sensitive period and risk of higher prices
Energy Ministry State Secretary Cristian Busoi identified the coming 10 days as particularly sensitive. A prolonged shutdown would increase the risk of higher electricity prices in the months ahead. Officials are preparing for the possibility of elevated prices through winter and into spring 2027.
Expensive European gas adds to that exposure. Replacing nuclear output with fuel-sensitive generation can raise supply costs even when sufficient capacity remains available. The decisive variable is the restart schedule, with every extension prolonging dependence on replacement generation and external supply.
