## Grid-scale battery energy storage

### Nevado

### A modular battery storage system

Nevado is a high-power, liquid-cooled battery energy storage system designed for grid-scale projects. It is built to operate reliably even in the most demanding conditions.

Three variants are available, starting from over 2 MW of power and over 4 MWh of capacity per unit. By combining multiple units, the system scales up to 50 MWh.

System capacity: 4–50 MWh

System power: 2–25 MW

### Completed projects

##### 14.2 MWh battery storage system at NTRN Energy Park

Our customer Enetron acquired a 5.5 MW / 14.2 MWh battery storage system for their NTRN Energy Park 01 site in Kiiminki. The system consists of two Cactos Nevado units and participates in Fingrid's reserve markets as well as wholesale electricity markets.

Total system power: 5.5 MW

Participates in FCR-N, FCR-D, and aFRR reserve markets, and intraday and day-ahead wholesale markets.

##### 10.3 MWh battery storage system in Kuhmoinen

We delivered a 10.3 MWh battery storage system to our customer Rando Grid in Kuhmoinen. The system automatically participates in both reserve markets and wholesale electricity markets, supporting grid stability and efficient energy use.

## How to get started

1. **Assessment**
   The project begins with an assessment of the site and grid connection possibilities, as well as the project goals.

2. **Permits**
   Battery storage projects typically require at least a construction permit. The process depends on the municipality and local zoning.

3. **Delivery**
   Cactos delivers, installs, and commissions the battery storage system.

4. **Operation**
   Once the project is complete, the system participates in electricity markets. Cactos operates and maintains the battery storage system.

## FAQ

### Which markets does a Cactos battery storage system participate in?

In Finland, Cactos battery storage systems participate in Nord Pool intraday and day-ahead markets, Fingrid's reserve markets (FCR-N, FCR-D, aFRR).

### What is the customer's responsibility in the project?

The customer is responsible for permitting, civil works and foundations, and the grid connection. For Nevado systems, the transformer and transformer substation are always included in Cactos' scope of delivery.
