Enery, an Austrian independent power producer, and LONGi, a Chinese solar technology manufacturer, have signed a strategic agreement for the development of 1.5 GW of solar and battery storage projects in Romania. The deal is positioned to support Romania’s renewable build-out across South-East Europe.
The cooperation covers projects scheduled for implementation between 2026 and 2027. LONGi Solar Europe is expected to provide roughly half of the equipment needed across Enery’s Romanian renewable portfolio.
Ogrezeni solar plant and battery storage details
A key element of the agreement is the Ogrezeni project. It combines a 761 MW solar power plant with a battery energy storage system exceeding 1 GWh. The facility is expected to reach commercial operation in 2027.
The Ogrezeni complex is projected to generate enough electricity to meet the annual needs of approximately 684,000 households. As part of the module supply, LONGi will deliver more than 1.1 million Hi-MO9 Back Contact solar modules for the project.
Module technology and operating-life claims
LONGi states that the Hi-MO9 Back Contact modules offer conversion efficiencies of up to 24.8%. The company also says the modules are designed to maintain performance over a 30-year operating life with limited degradation.
The Ogrezeni solar-plus-storage complex is expected to become one of the largest integrated renewable energy projects in Romania. The project structure links hybrid generation with battery storage intended to support grid flexibility and renewable integration.
Battery pairing trend for large-scale renewables
The agreement aligns with a broader market trend in which large-scale renewable developments are increasingly paired with battery storage systems. Developers use such combinations to improve energy delivery profiles and reduce curtailment risks.
Battery storage is also described as a way to capture greater value from electricity market volatility within these projects. In this context, Enery’s Romanian pipeline under the agreement includes both solar generation capacity and battery energy storage components.
