Romania has completed the first phase of the Gura Ialomiței battery storage project in Ialomița County. The newly commissioned installation adds 150 MW of power capacity and 300 MWh of storage. Electrogrup said the facility is among the largest operational battery energy storage systems in the country.
Project developers and next-phase timeline
The project was developed by Electrogrup, part of the E-INFRA group. Electrogrup confirmed that work on the next development phase will start without delay following commissioning. The company said the expanded installation is expected to provide additional grid flexibility as Romania increases its renewable generation.
Electrogrup linked the storage buildout to the integration of wind and solar into Romania’s electricity system. The company said the project supports balancing needs as renewable output grows. The statement also positioned the site as part of a broader expansion of battery storage capacity.
Construction schedule, partners and grid connection
Construction of the first phase took seven months, according to Electrogrup. The work was completed despite challenging winter conditions and a tight implementation schedule. The facility was developed in partnership with Aukera Energy.
Connection to the national transmission network was carried out in coordination with system operator Transelectrica. Electrogrup said this arrangement supported smooth integration into Romania’s high-voltage infrastructure.
Portfolio impact and completed storage projects
Electrogrup described commissioning at Gura Ialomiței as another milestone in its energy storage portfolio. With this project, the company said it has delivered more than 1 GWh of installed battery storage capacity across Romania. It also stated that Gura Ialomiței is the sixth completed storage project in its portfolio to date.
The company said battery storage can help manage variability associated with increasing wind and solar generation. It described a role for storing electricity during periods of high production and releasing it during peak consumption.
Second-phase preparations for expanded deployment
Preparations for a second phase are already underway, Electrogrup said. The company indicated that the project is expected to become a more significant element of Romania’s energy transition strategy. It also cited long-term efforts to modernize the power sector and strengthen energy security.
