Motor Oil Renewable Energy (MORE) has commissioned the Stalpu 2 hybrid power plant in Romania, marking the company’s first renewable-energy investment outside Greece and its first project combining solar generation with battery storage technology.
The facility integrates a 63 MW solar photovoltaic plant with a battery energy storage system (BESS) featuring 10 MW of power capacity and 21 MWh of storage capacity. The combination of renewable generation and storage allows the project to retain part of its electricity output and release it during periods of higher demand, improving grid flexibility, operational efficiency, and system stability.
MORE expects the Stalpu 2 hybrid project to generate approximately 76 GWh of electricity annually, enough to supply around 32,000 households. The company estimates that the renewable facility will help reduce more than 26,000 tonnes of CO₂ emissions each year, supporting Romania’s decarbonisation objectives and the wider energy transition in Southeast Europe.
The commissioning of Stalpu 2 represents a major milestone for MORE’s international expansion strategy, as it marks the company’s entry into the Romanian renewable-energy market and its first step beyond Greece. The project also highlights the growing importance of hybrid renewable assets, where solar generation and storage are combined to address intermittency challenges and create additional value in increasingly flexible electricity markets.
With renewable capacity expanding across the region, projects such as Stalpu 2 demonstrate the shift toward a new generation of energy investments focused not only on producing clean electricity, but also on improving market integration, grid resilience, and long-term energy security.
