The storage unit has an installed capacity of 24 MWh - (6MW x 4h) and it was built by Monsson as integrator, according to its own design, in a unique concept utilizing in-house developed know-how.

The project represents the first stage of in total 216 MWh storage unit to be installed until end of the year at the same location. The concept is modular and suitable for large scale applications.

The Monsson energy storage facilities are developed special for harsh climate conditions, utilizing the latest technologies in monitoring and safety systems for that kind of products.

The controlling software created by Monsson is useful both for electricity storage operation and for the electricity trading.

The Lithium Ion batteries are locally produced by the Romanian company Prime Batteries Technology. The storage unit is charged with energy produced by the Wind Farm, by the 35 MW PV project under construction, named Gălbiori 2, which will be grid connected end of 2024 and from the national grid when there is no wind or sun.

The control of the hybrid project is fully automatic, without local operational staff and the software is developed by Monsson.

"The investment was done on equity with the goal to prove the idea of increasing the renewable energy penetration in national grids, through renewable energy hybridization concept, consisting of photovoltaic, wind and storage. The hybridization with storage is reducing the volatility of renewable energy helping also balancing of the National Energetic System. The storage of renewables will lead in the end to reducing electricity bills for end consumers. With this project we are testing the functionality of the battery to demonstrate the immediate benefits of storage facilities attached to renewable energy sources. We want to promote such solutions both in Romania and across Europe," said Sebastian Enache, Monsson, member of the Board.

“The energy transition towards renewable needs to be done in a sustainable way. Volatility is a problem that needs to be addressed and resolved, as much as possible at the source. Company Prime took its role as solution supplier since 2016. In the market we are seen as battery producers but our main buiness is Lithium Ion battery solutions. And this is how us and Monsson found common ground, because their extensive experience in renewable energy that led to projects as this one”, explained Vicențiu Ciobanu, CEO Prime Batteries Technology.

Present for over 17 years in the renewable energy market in Romania, Monsson has become the leading supplier of projects electricity from renewable sources, with a portfolio of over 5GW of wind and photovoltaic projects. The company provides turnkey services for Design, Development, Construction and Operation of renewable energy projects and energy storage solutions.

Prime Batteries is the local leader in Lithium Ion battery manufacturing. The company has a lithium-ion battery production capacity of 2.3GWh/year in Bucharest, being vertically integrated including the production of Li-ion cells. In 2023 the company has produced more than 65 MWh of batteries for the Romanian market, mostly in renewable energy applications.
