We offer a lease plan to all customers with no upfront investment. The contract period is usually ten years long and completely maintenance-free for you.
After the lease period, the unit is your property. You can choose whether to continue the plan or to enjoy the unit in another way for many years to come.
Sounds pretty cost-efficient, right? By harnessing the power of each Cactos One to support the national electricity grid at critical times, we unlock revenue-generating potential. This reduces the cost of ownership for our customers.
*Applies to our Fifty and All in plans.
What does supporting the electricity grid mean?
The electricity network must always balance the supply and demand (namely production and consumption) of electricity. The frequency of the AC network is a measure of the balance of production and consumption, and when the network is balanced (i.e. consumption and production are balanced), the frequency is 50 Hz.
Consumption naturally varies throughout any given day and with the increased penetration of renewable energy production in the overall energy mix, the variability in production is increasing. When there is more production than consumption, the frequency rises above 50 Hz. and when there is insufficient production, the frequency falls below 50 Hz. The Transmission System Operator (TSO), for example Fingrid in Finland, is responsible for managing this balance and it procures grid services, which are also known as ancillary services, from the market in order to ensure balance of the overall network can be maintained.
When the frequency decreases, participants in the grid services market provide power (i.e. supply) to the grid and when the frequency increases, participants in the grid services market provide load (i.e. demand). The operation of the grid services market and availability of sufficient capacity are essential for the overall resilience and uninterrupted operation of the electricity grid.
Each Cactos One unit participates in the grid services market and thus supports the safe operation and resilience of the electricity grid. The revenues from participation in the grid service market can be used to fund our customers' Cactos One system, and furthermore increases the utilization rate of the system.
How does the Cactos One system participate in the grid services market?
The Cactos Spine cloud control system strives to find the most economically beneficial operation for each Cactos One system at any given time of the day. On some occasions the operation is purely time/load shifting, whilst sometimes it is purely grid services. Most often, it is a combination of each. The goal of the Cactos Spine is to maximize the financial benefit of each unit's total power and capacity.
It should be noted that equalization of peak consumption and back up power functionality are always available to our clients, regardless of the participation in grid services or time shifting operations.
How does participation in the Grid Services market benefit Cactos' customers?
Cactos One systems participate in the grid services market in their given jurisdiction/region. The customer can choose who bears the risk exposure to the grid services market revenues, which vary from day to day and month to month. This can be Cactos, the customer themselves or shared between both the customer and Cactos.
There are three contract options, with the only difference between them being the distribution of the income generated from the grid services market.
The customer can choose whether the grid services market income will go to the customer or to Cactos, or whether it will be divided in half between the parties. The price of the contract is determined by the contract model. Participating in the grid services market therefore benefits the customer in any case, either in the form of a cheaper lease rate or as direct income.
How much income can be expected from the grid services market?
The yield is determined by the given grid services market, which is a marketplace maintained by the Transmission System Operator. Information on realized prices can be found on your local Transmission System Operator’s website (e.g Fingrid, Tennet etc. depending on jurisdiction).
Why does Cactos offer three different price structures / contract options and what is the difference between them?
Many of our customers have advised that they have previously considered participating in the reserve markets as part of their evaluation of the benefits of energy storage solutions. However, participation has lagged, for example due to the complexity of the technical requirements required for participation.
Cactos opens participation in this market to everyone. We operate each unit and bear the responsibility for such on behalf of the customer. In this regard, we offer three different contract models, with the only difference being related to how the revenues obtained from the grid services market are distributed? This determines the size of the fixed monthly payment.
