AJ Brand battery storage: 2,204 MWh contracted in Romania — NRG-IA

Four major hybrid projects underway — AJ Brand delivers 2,204 MWh of battery storage Romanian company AJ Brand is currently delivering 2,204 MWh of battery energy storage system (BESS) capacity across four major utility-scale projects in Romania, scheduled for energization in the second quarter of 2027. This massive storage volume is integrated into hybrid solar-plus-storage and wind-plus-storage parks, as reported by local economic outlets e-nergia and Economica.net based on company social media updates. The contracted projects, which target a total capacity of approximately 2,400 MWh, represent a major leap forward for the national energy infrastructure. These storage systems will connect directly to the transmission and distribution grids, offering enhanced flexibility for intermittent renewable energy generation. Integrating such volumes will help mitigate grid congestion, an increasingly urgent issue as new green capacities come online. The development of these BESS projects by a local partner highlights the growing capability of Romanian engineering, procurement, and construction (EPC) firms in a market previously dominated by international giants. AJ Brand is thus cementing its position as a key energy technology integrator in the region, demonstrating the technical capacity to manage utility-scale storage projects of hundreds of megawatt-hours. The rapid expansion of renewables and the critical need for grid balancing The urgent need for utility-scale storage in Romania is driven by the rapid build-out of new solar and wind farms, which frequently cause congestion on the national grid managed by Transelectrica. Without adequate storage capacity, excess power generated during peak solar hours cannot be safely absorbed by the transmission system, leading to forced curtailment for operators. Furthermore, extreme price volatility on the Bucharest spot market (day-ahead market) managed by OPCOM, where negative prices during midday hours have become a common reality, incentivizes private developers to co-locate batteries with their generation assets. This hybrid configuration allows developers to avoid selling electricity at rock-bottom or negative prices, storing it instead for evening hours when demand and prices peak. Flattening the price curve and reducing imbalance risks for the power system Integrating over 2,200 MWh of storage capacity by 2027 will directly support grid frequency stabilization and help lower system service costs, which are ultimately borne by end-consumers on their bills. Batteries allow cheap daytime power to be stored and discharged when demand and prices peak, reducing the need to fire up expensive gas or coal power plants. For renewable energy developers, these battery systems drastically reduce exposure to high imbalance costs. Instead of paying penalties for deviations between forecasted and actual generation, wind and solar operators can leverage BESS to deliver exactly the volume of power committed to the grid, thereby securing their cash flows. The 2027 commissioning deadline and supply chain bottlenecks All four projects in AJ Brand's portfolio are slated for energization by the second quarter of 2027, according to reports from e-nergia and Economica.net . This tight timeline of roughly one year puts considerable pressure on global supply chains for lithium-ion battery cells, at a time when global demand for stationary storage is at record highs. The rapid pace of installation will also hinge on the speed of permitting and connection approvals from Transelectrica and regional distribution system operators. Grid connection delays remain the primary administrative risk to the timely completion of these mega-storage projects in Romania beyond the 2027 target.
