Battery energy storage (BESS)
Batteries that work alongside your park.
We develop battery energy storage systems for power producers and industrial consumers — including solutions connected through the existing transformer substation, with no consumption from the grid.
What it includes
What a storage project covers
- Measurements at the connection point and analysis of the grid connection
- Sizing of the battery and the power conversion system (PCS)
- Hybrid PCS: a single inverter for the panels and the battery
- A dedicated solar field for charging the battery
- A separate meter for the energy sold on the free market
- Design, construction, commissioning and maintenance
What you get
What the owner and the system gain
Existing connection, new capacity
Storage uses the connections and transformers that are already built.
The fixed tariff stays
In the proposed scheme the existing park keeps its eligible producer status, while the new installation sells on the free market.
Concrete projects
Five storage projects of about 5 MWh each at eligible producers and 70 MW / 140 MWh at CET-Nord, in development.
Frequently asked questions
Short answers
Can a battery be installed at a park with eligible producer status?
Current regulation does not clearly provide for a battery connected to the same transformer as an eligible producer. Together with the ECOENERGETICA Association and ANRE we are working to improve the regulation. The proposed solution: one transformer, two regimes — the park remains an eligible producer, while the new installation sells on the free market through a separate meter.
What is a hybrid PCS?
A power conversion system that uses a single inverter for both the solar panels and the battery.
