P-ZERØ
Know what your wind and solar sites will deliver, before they deliver it.
P-ZERØ combines high-resolution weather forecasts with each plant’s own history to predict generation, with an honest range around every number.

Illustrative data for a 100 MW wind site.
Forecast horizons
- Intraday
- Rolling updates through the day for dispatch and balancing.
- Day-ahead
- Hourly or finer forecasts for scheduling and market bids.
- Week-ahead
- A longer view for maintenance planning and contract management.
What goes in
- High-resolution weather
- Downscaled forecasts at 90 m and 5 minute resolution through our partnership with Meteomatics.
- Your plant’s history
- SCADA and metering data train a model for each site, so it learns how your turbines and panels actually behave.
- Availability and curtailment
- Planned outages and curtailment are folded in, so the forecast reflects what the plant can export.
What comes out
P10, P50 and P90 forecasts for every site, delivered by API, scheduled file or dashboard. The range tells your traders and grid operators how much to trust each hour, not just what to expect.
The same data drives asset management: compare expected against actual output to spot underperforming turbines and inverters early. Typical accuracy figures to be added.
Weather data from Meteomatics
Since 2024, FALX has partnered with Meteomatics, whose weather API provides 90 m spatial and 5 minute temporal resolution across Africa.
