In early 2025, frequent negative electricity prices swept across Europe. According to the latest analysis by AleaSoft Energy Forecasting, Portugal and Spain recorded the lowest hourly prices in history at the end of March. As April progressed—particularly during the Easter weekend—major European electricity markets repeatedly experienced zero or negative electricity prices.
This trend indicates a growing share of renewable energy generation and its associated challenges. When the grid cannot absorb surplus renewable electricity, utilities essentially pay consumers to use the excess power.
All Swatten energy storage products now support the Dynamic Pricing Mode to address these market shifts.
Our advanced cloud-based EMS system powers this feature and connects through our proprietary WiFi logger, with no additional hardware required, such as an energy hub. By accessing real-time electricity pricing data and user-defined buy/sell thresholds, the system automatically generates optimal operation strategies for the inverter and seamlessly adjusts its behaviour to match market conditions.
Swatten's Dynamic Pricing Mode automatically charges your system when electricity is cheap or even negative and discharges it when prices are high. This allows you to save on electricity bills and potentially generate profits with no extra hardware or complicated setup needed—just smarter energy working effortlessly.
Three Key Benefits
1. Peak-valley arbitrage driven by real-time grid pricing
When prices spike, the system discharges to the grid to generate revenue. When prices fall, especially during negative pricing events, it draws electricity from the grid for storage, effectively "earning while charging."
2. Better integration of renewables through price-based optimization
Electricity price volatility mirrors the fluctuations in renewable energy supply. Dynamic Pricing Mode enables energy storage systems to "go with the flow," charging and discharging in sync with the market. This stabilises the grid and helps accommodate more solar PV and wind energy into the system.
3. AI-powered optimization for smarter profit-making
The Swatten system continuously monitors real-time electricity prices to adjust energy flow by leveraging big data and AI algorithms. This software-driven intelligence means the system doesn't just store energy; it actively participates in the energy market to maximise value.
Conclusion
When combined with dynamic pricing strategies, Swatten's energy storage systems can increase renewable energy penetration to over 80%, supporting a more sustainable grid.
With AI-driven energy dispatch, system trading efficiency improves by up to 15%, significantly shortening the return-on-investment period for end users.
