Romania is expanding Black Sea gas and utility-scale renewables, including a planned 8 bcm-a-year plateau at Neptun Deep and a 612 MWh battery project. The combination of domestic production, flexible generation, storage and cross-border transmission is building the ingredients for a regional energy hub.
Gas projects target higher output
Carlyle and the European Bank for Reconstruction and Development (EBRD) agreed to sell Black Sea Oil & Gas (BSOG), operator of the Midia gas project in the Black Sea, to Mazarine Energy. BSOG’s Midia project produces around 1 bcm of gas a year, equivalent to roughly 10–12% of Romanian demand.
OMV Petrom and Romgaz are developing Neptun Deep, which holds around 100 bcm of recoverable gas. The project is designed to produce about 8 bcm a year for close to a decade, with first gas targeted for the first half of 2027 and development costs of around €4 billion. At full output, it could almost double Romanian gas production and create export capacity for neighbouring markets.
Solar and storage add capacity
Nofar connected a 74 MW solar project in Romania. OMV Petrom and Renovatio also brought three solar parks with a combined gross capacity of about 130 MW into commercial operation.
ENNA Solar agreed to acquire a hybrid project combining 166 MW of solar capacity and 612 MWh of battery storage. Construction is targeted to start from Q1 2027, with operations expected to begin in Q1 2028.
Regional role and execution risks
Domestic gas can provide flexible generation and export optionality, while solar and battery energy storage systems can reduce fuel burn and add balancing resources. Romania is one of the few South-East European markets where gas and renewable growth are happening simultaneously, creating both competition and complementarity in power-sector investment.
The development pipeline also includes flexible thermal capacity and cross-border transmission. Execution risk, grid integration and Black Sea infrastructure security are identified as the main constraints on Romania’s energy development.
