SINEXCEL Supports 7.5MW/15MWh Battery Energy Storage Project in Romania
In a significant move to bolster Europe’s energy infrastructure, SINEXCEL is supporting the deployment of a 7.5MW/15.04MWh battery energy storage system (BESS) in Curtea de ArgeÈ™, Romania. This utility-scale project marks another expansion of SINEXCEL’s footprint in the European market, highlighting the growing importance of energy storage in ensuring grid stability and enabling advanced energy trading strategies.
Enhancing Grid Flexibility Through Price Arbitrage in Romania battery storage
The primary objective of this state-of-the-art facility is to engage in price arbitrage. This strategy involves charging the batteries when electricity prices are low—typically during periods of high renewable energy generation—and discharging the stored energy back into the grid when demand and prices are high.
By doing so, the project not only optimizes energy trading but also provides crucial services to the grid. It enhances responsiveness to fluctuations in supply and demand, improves overall operational efficiency, and supports a more flexible, market-oriented approach to energy management. This capability is essential for integrating intermittent renewable sources like wind and solar power seamlessly into the national grid.
Advanced Technology at the Core of Romania battery storage
The project is built around SINEXCEL’s advanced 1250kW Power Conversion Systems (PCS). These systems are the core technology responsible for the bidirectional flow of energy, converting DC power from the batteries to AC power for the grid and back again with maximum efficiency.
A key advantage of SINEXCEL’s solution is its scalable and flexible architecture. The PCS units can be integrated into various medium-voltage station configurations to meet diverse project requirements, including:
- 20ft MV station: 2.5MW/3.15MW
- 40ft MV station: 5MW/6.25MW
- 40ft MV station: up to 9.45MW/10MW
This modular design simplifies the installation process, reduces lifecycle costs, and allows developers to efficiently scale capacity as needed, making it an ideal solution for large-scale energy projects.
Project Development and Timeline for Romania battery storage
The project was developed by Energy Solar NRG SRL and successfully secured non-recourse financing from DHB Bank in February 2025. The facility is on track for full commissioning and grid connection by September 30, 2026.
SINEXCEL’s involvement underscores its reputation as a trusted partner in the global energy sector. Founded in 2007, the company specializes in energy storage, EV charging, and power quality solutions. With a proven track record of over 5,000 deployments worldwide, representing more than 15GW/40GWh of installed capacity, SINEXCEL continues to drive innovation in energy technology alongside industry leaders.
This project in Romania is a testament to the critical role that battery energy storage will play in the future of energy, creating a more resilient, efficient, and sustainable power grid for generations to come.
