Saudi renewable-energy developer Altaaqa Renewables has secured regulatory approval for two solar-plus-storage projects in Romania, advancing a combined 63 MW of photovoltaic capacity in the Dobrogea region and adding approximately 80 MWh of battery energy storage.
The Cuza Voda 1 and Cuza Voda 2 projects have reached ready-to-build status following approval by Romania’s energy regulator, ANRE. Construction is expected to start in the first quarter of 2027, with both developments targeting commercial operation by the end of 2028.
The larger Cuza Voda 2 project will comprise 34.7 MW of solar capacity alongside an 11.29 MW/45.13 MWh battery storage system. The installation is designed to combine photovoltaic generation with flexible electricity storage, allowing part of the energy produced during periods of strong sunshine to be delivered later.
Cuza Voda 1 will add a further 28.3 MW of photovoltaic capacity and an 8.94 MW/35.1 MWh battery system. Together, the two projects will provide 20.23 MW of battery discharge capacity and approximately 80.23 MWh of storage, strengthening their ability to manage electricity delivery across different market periods.
The integrated storage systems are intended to shift part of daytime solar production into later hours, helping the projects manage grid deliveries and potentially capture higher wholesale electricity prices when market conditions are favourable. Battery storage can also provide greater operational flexibility as solar generation fluctuates and intraday price differences become more pronounced.
The developments reflect a broader shift in Romania’s renewable-energy investment pipeline, where new solar projects are increasingly being developed alongside battery storage rather than as stand-alone photovoltaic facilities. As installed solar capacity expands, the ability to manage output timing is becoming more important for both project economics and integration into the electricity system.
For developers, combining solar generation with storage can create additional options for managing market exposure, although the commercial benefits depend on electricity price spreads, battery efficiency, degradation, grid access and operating costs. The configuration and duration of each battery must therefore be assessed against the specific revenue opportunities available to the project.
With construction planned for 2027 and commercial operation targeted for 2028, Cuza Voda 1 and Cuza Voda 2 will add to Romania’s emerging portfolio of hybrid renewable-energy assets. Their development illustrates how battery integration is becoming an increasingly important part of solar project design as developers seek greater flexibility in a more variable electricity market.
