Romania recorded one of Southeast Europe’s strongest supply-side performances in Week 42, meeting a sharp rise in power consumption while reducing net electricity imports. Consumption climbed 9.13% to 983.54 GWh, among the region’s largest increases. Unlike Serbia, Romania did not rely primarily on imports to cover the additional demand.
Wind and solar generation rose 50% to 343.73 GWh, with wind output more than doubling. Hydroelectric production increased 12.72% to 168.93 GWh. Thermal generation grew 19.82% to 368.48 GWh as both coal- and gas-fired plants produced more electricity.
With output rising across these sources, Romania reduced net electricity imports by 59.06% to 77.57 GWh, despite higher domestic consumption. Wholesale electricity prices nevertheless increased 9.72% to €240.51/MWh. Stronger local generation therefore coincided with a continued rise in prices.
Domestic supply strengthened as regional prices rose
Romania’s Week 42 balance highlights the difference between physical energy security and market pricing. A country can depend less on imported electricity while still facing high wholesale prices when neighbouring markets, fuel costs and marginal generation remain expensive. In Romania, prices remained linked to tight conditions in Hungary, Serbia and Bulgaria, as well as elevated European gas costs.
For investors, Romania’s diversified generation fleet provides a useful model. Wind output rose sharply, hydro added flexible production, and thermal plants increased generation when required. Together, these sources enabled the power system to absorb stronger consumption without a proportionate rise in cross-border dependence.
That diversification is likely to become more valuable as renewable penetration increases. Romania is adding substantial wind and solar capacity, but Week 42 showed that renewable output is only one part of the system requirement. Reservoir hydro, gas generation, batteries, transmission infrastructure and demand flexibility are needed to turn variable generation into dependable supply.
Storage and regional trade implications
The high-price environment also improves the potential economics of storage. At average weekly prices of approximately €240/MWh, significant differences between low- and high-price hours can create attractive arbitrage opportunities. Storage may also reduce the need to dispatch more expensive thermal units during peak hours.
Romania’s lower import requirement has strategic significance for the wider Balkans. When Romania needs fewer imports, electricity that might otherwise flow to the country remains potentially available to neighbouring systems. Strong Romanian generation can also create additional export potential when renewable conditions are favourable.
Week 42 reinforced Romania’s growing role as both a major national electricity market and a regional balancing force. Its investment case is increasingly focused not only on adding renewable megawatts, but also on building a generation and flexibility portfolio that can support domestic security and regional electricity trade.
