Earn by supporting the grid

As renewable energy gets more common, the electricity grid needs more flexibility to stay balanced. With Cactos, you automatically participate in ancillary service markets run by your local transmission system operator, helping to stabilize the grid.

This also means additional income for you. In 2023 and 2024, revenue from ancillary service market participation has at least covered our customers’ cost of leasing a Cactos system.

Cactos Spine handles everything automatically, ensuring your system is always working for you.

The compensation is determined by the ancillary services market. The amount depends on factors such as your Cactos energy storage system's size, market prices, and the number of hours you offer reserve capacity. Currently, participation is available in Finland. Contact us to learn more about your country's status.

FAQ

Olipa kiinteistösi millainen tahansa, jokainen päivä energiamaailmassa on erilainen. Alla kerrotut hyödyt auttavat sinua suunnistamaan sähköverkossa säästäen samalla aikaa, energiaa ja rahaa. Ja vieläpä automaattisesti, sillä asiakkaana sinut ei tarvitse puuttua järjestelmän toimintaan, Cactos Spine tekee sen sinun puolestasi.

What kind of product guarantee does Cactos have?

Cactos offers a full warranty on the equipment it manufactures for the entire leasing period. The warranty covers both labour and necessary spare parts.

How do I know how many units I need?

The amount of capacity to be installed depends on a number of factors such as the size of the electrical connection at the installation site, the characteristics of the potential PV system and other factors related to electricity consumption. Our experts will always design the optimal package together with the customer, taking into account the various factors that affect the sizing of the system.

How much capacity is there in one Cactos unit?

The capacity of Cactos units depends on the model. 

The smallest Cactos unit, Cardo, has a battery capacity of 130 kWh and a power of 45 kW. Cactos Fero and its outdoor sibling Steno have a battery capacity of 215 kWh and a power of 92 kW.

Of our outdoor units, Cactos Yavia has a battery capacity of 430 kWh and a power of 184 kW, Mylo has a battery capacity of 520 kWh and a power of 260 kW, and Nevado has a battery capacity of 4 180 kWh and a power of 2 195 kVA.

Cactos units can be installed in parallel as needed, achieving greater storage capacity and power. For example, a system of ten Cactos Mylo units would result in a total battery capacity of 5.2 MWh and a power of 2.6 MW.
