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 as support for Romania’s role among the fastest-growing renewable energy markets in South-East Europe. The agreement covers project development within a timeframe for implementation between 2026 and 2027.
Under the cooperation, LONGi Solar Europe is expected to supply roughly half of the equipment needed across Enery’s Romanian renewable energy portfolio. The agreement includes a specific focus on the Ogrezeni project as a central element of the partnership.
Ogrezeni solar plant and battery storage details
The Ogrezeni project combines a 761 MW solar power plant with a battery energy storage system exceeding 1 GWh. The facility is expected to enter commercial operation in 2027. It is projected to generate enough electricity to meet the annual needs of approximately 684,000 households.
As part of the contract, LONGi will deliver more than 1.1 million Hi-MO9 Back Contact solar modules for the Ogrezeni development. The company states that the modules have conversion efficiencies of up to 24.8%. LONGi also says the technology is designed to maintain strong performance over a 30-year operating life with limited degradation.
Hybrid generation and storage pairing in regional renewables
The Ogrezeni solar-plus-storage complex is expected to become one of the largest integrated renewable energy projects in Romania. The project is described as supporting grid flexibility and renewable integration through hybrid generation and storage assets. It is also linked to long-term energy security across the region.
The agreement aligns with a broader market trend in which large-scale renewable developments are increasingly paired with battery storage systems. Such pairings are aimed at improving energy delivery profiles and reducing curtailment risks. They are also intended to capture greater value from electricity market volatility.
