Axpo, Switzerland’s largest power producer and a leading international energy trader, manages a renewable portfolio totaling several gigawatts across the globe. For its European portfolio, the team relies on Meteomatics’ power forecasts based on EURO1k to sharpen day-ahead and intraday trading. This unique model diversification has proven decisive, reducing balancing costs and allowing for stronger weather-driven decision-making across the team.

Business Value

Model Differentiation as a Trading Advantage

In energy trading, staying ahead means more than just watching the weather, it means understanding it better than anyone else. Most traders rely on the same blend of weather models, and that often leads to the same conclusions. Axpo wanted to break away from that pattern.

EURO1k, Meteomatics’ proprietary model, brings a fresh perspective, adding a layer of insight others don’t see. Built specifically for the complex terrain and weather systems of Europe, it runs at 1-kilometer spatial resolution, with forecasts every 15 minutes and model updates every hour, delivering sharper and faster insights than standard models.

By continuously backtesting forecast performance across markets and technologies, the team identifies where EURO1k-based power forecasts perform best and uses those insights to guide both day-ahead and intraday bids. It’s all about using the right forecast, at the right time.

We use EURO1k strategically to achieve better trading conditions and lower costs.

EURO1k’s fast update cycle is especially valuable for intraday trading, where conditions can shift in minutes. Each refresh delivers a new high-precision signal, helping Axpo anticipate change and secure stronger market positions.

EURO1k’s high-resolution forecasts provide a unique market signal, offering traders an edge in day-ahead trading decisions. In this example, we can see that while other models didn’t capture the timing and magnitude of the wind ramp, EURO1k tracked the real production more closely.

Operational Impact

Flexibility That Scales

Axpo’s portfolio is constantly expanding, with assets spread across several countries. With the Meteomatics Weather API, the team can pull up forecasts tailored to the exact location of each asset, from regional PV installations to wind farms or even selected points of interest correlated with market signals.

This flexibility enables traders to act fast, basing decisions on granular, real-time insights.

We can easily place points on the map, select solar panel types, set capacities, and get forecasts that match our setup. We even look at specific weather parameters that tend to move prices. That helps us trade smarter.

All of this is integrated directly via API into Axpo’s internal systems, allowing analysts to focus entirely on performance, not processing.

Risk and Resilience

Integrating Weather Alerts for Prevention

Weather doesn’t just affect prices. It can cause real damage if you're not prepared. That’s why Axpo is now exploring how Meteomatics’ data can support early warnings for events like high winds or icing. Though these events are rare, they can trigger hundreds of thousands in losses if not anticipated.

These alerts are like insurance. If we can avoid even one costly event per year, the value is clear.

Customer Success

A Human Touch Behind the Forecast

For Axpo, success with Meteomatics is also about knowing how to make the most of weather forecasts.

We do more than just deliver numbers. Our team of meteorologists and Axpo’s dedicated customer success manager are always on hand to help interpret results and fine-tune configurations. Whether it's digging into model performance, correlating parameters with market signals, or preparing for extreme events, this ongoing exchange turns data into confident decisions.

This close collaboration has become a key part of Axpo’s trading workflow. It ensures that every forecast truly pays off.

We’re not meteorologists, but Meteomatics helps us think like them. Our regular conversations help us make better use of the data and get more out of it.
