Your internet connection earns money while you sleep
Our trading algorithms leverage price fluctuations in the spot, intraday, and balancing markets to maximize the returns from your battery facility, wind turbine, or commercial plant — fully automated, around the clock.
Meganet VPP Platform
LiveThe algorithms that find the best price
Our VPP and EMS platform continuously monitors the markets and automatically shifts energy to where the value is highest.
-
AI-powered price optimization
The algorithms predict price fluctuations and place bids automatically.
-
Multi-market optimization
The flexibility is continuously allocated to the most valuable market.
-
Risk management
Built-in safety margins protect the plant's service life and warranties.
Three markets, one strategy
Spot market
Buy low, sell high — based on day-ahead prices from Nord Pool.
Intraday
Fine-tuning positions close to the operating hour for additional returns.
Balancing market
Participation in system services when it is more valuable than pure arbitrage.
The price fluctuations that drive the arbitrage
How to get started
Potential analysis
We are assessing your grid connection capacity and historical prices to identify the specific earnings potential.
Dimensioning
We determine the optimal battery size in relation to your grid connection and expected trading patterns.
Installation
Our own electricians will handle the connection of the battery to the existing power supply.
Automated operations
From then on, our algorithms trade around the clock, without you having to monitor the market.
Passive grid connection vs. spot price optimization
A passive grid connection does not in itself take advantage of price fluctuations in the electricity market.

2 MW wind turbine + battery — what does that mean in practice?
Example based on a 2 MW / 4.63 MWh battery system connected to an existing 2 MW wind turbine in DK1.
Prerequisites
Result
Based on actual wind and spot data (DK1, Apr.–Jul. 2025), annualized. Gross total before operations, service, tariffs, and tax — not a guarantee of future returns.
What can spot market arbitrage provide for your facility?
The battery charges when the spot price is low and discharges when the price is high. The default values below are based on actual system prices and a completed backtest against historical DK1 spot prices, showing a system that is already profitable with a short payback period. Please feel free to adjust the assumptions for your own system.
The calculation is indicative and based on actual installation costs and a completed backtest of a battery system against historical DK1 spot prices (Energy Data Service, Apr.–Jul. 2025). Contact us for a specific calculation for your facility.
Good to know about arbitrage and spot optimization
How high is the risk involved in arbitrage trading?
Our algorithms operate within predetermined safety margins that protect battery life and warranties, ensuring the trading strategy never compromises the facility's technical limits.
Does extra cycling affect battery life?
The arbitrage cycles are incorporated into the facility's overall load plan, and the algorithms balance trade value against the permitted cycle load so that the facility's warranty is not adversely affected.
Can arbitrage and spot optimization be combined with ancillary services?
Yes. Our EMS continuously allocates capacity between FCR, aFRR, mFRR, and arbitrage, depending on what provides the most value at any given time.
What is the difference between spot and intraday trading?
The spot market determines prices the day before the operating hour, while the intraday market makes it possible to fine-tune positions closer to the actual operating hour, when new information becomes available.
Should I monitor or manage the trade myself?
No. Our trading algorithms monitor and trade automatically 24/7 — you do not need to track the prices or place bids yourselves.
Why is there a difference in prices in DK1 and DK2?
The two price areas are affected by different transmission links and market conditions, which can lead to significant hour-by-hour price differences — something our algorithms take into account. See the full explanation of the DK1/DK2 division under System Services.
What does it require from my existing grid connection?
We are evaluating your grid connection capacity and historical consumption patterns to determine the optimal battery size to install.
Can I use my existing wind turbine for this?
Yes. A battery is connected to the same grid connection as the wind turbine, so excess production can be stored and sold when the price is highest, instead of being curtailed. See the case above for a concrete example with a 2 MW wind turbine.
How quickly does the system pay for itself?
It depends on your specific grid connection, historical prices, and system size. Use the ROI calculator above for an initial estimate, or contact us for a detailed calculation based on your actual data.
Who owns the battery?
As with our other solutions, you can choose full ownership, co-ownership with Meganet, or an operating agreement where we own the facility and you receive a share of the earnings.
How many full cycles do you expect per year?
In the actual wind turbine case, the activity corresponds to approximately 386 equivalent charge/discharge cycles per year — well below the battery's technical limit, so the warranty is not affected.
What is the efficiency of a battery in arbitrage operation?
Typically around 95% for both charging and discharging, corresponding to a total round-trip efficiency of approx. 90% — this is factored into all business case figures on this page.
