On Friday at 11:39 a.m., commercial solar output, excluding prosumers, reached 2,048 MW, while demand stood at slightly over 6,000 MW, Romanian media reported, citing data from the country’s transmission system operator, Transelectrica. The previous record, of 1,866 MW, was reported on June 16, 2025, at 12:33 p.m.
Although solar output is generally higher in summer, sunny winter days can create excellent conditions for photovoltaic generation, as panels do not lose efficiency from overheating and snow reflects additional light.
Transelectrica did not take prosumers into account, but had they been included, the figure would likely have been around 4,000 MW, according to Profit.ro.
With prosumers, solar would have covered about two thirds of demand
At the end of November 2025, there were nearly 290,000 prosumers in Romania, totaling 3.35 GW, according to the Romanian Energy Regulatory Authority (ANRE). For its part, the Romanian Photovoltaic Industry Association (RPIA) said that the country’s overall solar power capacity exceeded 7 GW in 2025.
At the time when solar production hit the 2,048 MW record, electricity output from nuclear energy and fossil fuels totaled around 1,300 MW.
On Romania’s day-ahead market, three hourly intervals with negative prices were recorded on Saturday, for the first time this year.
The increase in installed capacity is likely to lead to more intervals with negative prices
The increase in installed renewable capacity is likely to lead to a record number of days with hourly intervals of negative prices this year, Profit.ro noted.
