Green Energy
What we've been into lately
Greenbox is Grenergy’s StandAlone BESS platform, focused on aggregating utility-scale battery projects. To bring intelligence. To bring dynamism. To get the grid going
One of Europe's largest platforms
With a total pipeline exceeding 30 GWh of stand-alone battery storage, Greenbox is emerging as
one of the leading storage platforms in Europe. The company is advancing projects across its key
European markets: Poland (5 GWh in the pipeline), Romania (7 GWh), Germany (3 GWh), Italy (5.8
GWh), Spain (6 GWh) and the United Kingdom (4 GWh).
From storage to the grid
Benefits of energy storage systems
01
Instant flexibility
Batteries react in milliseconds to balance the grid’s supply and demand in real time.
02
Frequency and voltage stability
Keeping the grid at 50 Hz and maintaining stable voltage is essential. Batteries now act as the primary regulation system — a cleaner and faster alternative to fossil-based reserves.
03
Smoothing price volatility
Markets with high renewable penetration can be volatile. Batteries absorb excess energy and discharge it to the grid during peak demand and price spikes.
04
Zero-emission grid services
Historically, grid support relied on fossil fuels. Today, batteries do the job with zero emissions, offering a cleaner, faster, and more competitive solution.
Leading the way with energy storage solutions that offer a supply guarantee, powering security and ensuring a greener future
Inside the BESS storage system
Battery Rack
The battery rack in our Battery Energy Storage System (BESS) securely holds and organizes modules, ensuring alignment, easy installation, and maintenance. It also optimizes airflow for peak performance.
Lithium Ion Battery Pack
The powerhouse of our BESS is the lithium-ion battery pack. Comprising numerous individual lithium-ion cells, this pack stores and supplies electrical energy with exceptional efficiency. Renowned for their high energy density and long cycle life, these battery packs are perfectly suited for large-scale energy storage, ensuring reliable and sustained power supply whenever it’s needed most.
BMS (Battery management system)
The Battery Management System (BMS) monitors and controls the state of each battery cell, ensuring safe operation, preventing overheating, and managing charge levels. It is essential for maximizing battery life and maintaining ideal performance.
HVAC System
A heating, ventilation, and air conditioning system that maintains optimal temperatures for the operation of batteries and other sensitive equipment.
Fire Supression System
A fire protection system that detects and ensures safety in situations of overheating or fire risk.
AC
A type of electrical current where the magnitude and flow of electrons vary over time. BESS systems store energy as direct current, so they include inverters to convert the energy to alternating current, allowing its use in conventional applications and facilitating integration into the electrical grid.
Container
A modular structure designed to house all components of the energy storage system, providing physical protection and controlled conditions for its operation.
