Forecasts are crucial in optimizing renewable power plants with predictive controls. Solcast’s forecasts, and the resulting decisions we make with them, are front and center for our operators.
As far as we know, there's no provider that can provide a more accurate forecast.
Adding Solcast's weather data in our hydrogen storage systems improved our control strategy that responds well to weather patterns.
On top of our sophisticated solar modelling, Solcast's accurate data has elevated what we already have and allowed us to expand to new geographies.
Solcast's "Estimated Actuals" closes the gap for our owned and third-party solar portfolios.
Accurate real-time and forecasted weather data is crucial for assessing plant performance and maximizing the value of clean energy assets.
