Durch die Satellitenbilder können die Entwicklung der Wolkendecke und das Ertragsprofil für die kommenden Stunden in Verbindung mit den Wettervorhersagen verfeinert werden. Das Modul verwendet Satellitenbilder, die ein bis vier Mal pro Stunde abgefragt werden. Dank einer Feinmodellierung und hochentwickelten mathematischen Algorithmen wird der Energieertrag der kommenden Stunden mit einer gesteigerten Fähigkeit zur Abschätzung von Schwankungen und Unterbrechungsrisiken vorhergesagt.

Durch dieses Angebot kann beispielsweise der Bedarf an zusätzlicher Wärmeenergie in einem Energiemix mit hohem Solarenergieanteil moduliert werden. Ergebnis – die Reduzierung der Betriebskosten und eine bessere CO2-Bilanz.

The solar forecast service SteadySat was developed in response to intra-day forecasting needs (up to 6 hours in advance) and is intended primarily for network operators (TSOs and DSOs), but also for electricity producers, traders or suppliers. This production forecast service allows in particular to:

> Manage the injection gap recorded during the day compared to the previous day’s announcement, and reduce associated costs (penalties, risks);

> Set up and operate a storage system associated with a solar power plant;

> Efficiently exploit solar resources in an island environment or in non-interconnected areas, while reducing the use of fossil fuel energy;

> Manage the hybridization of a fossil fuel off-grid power plant using solar power to reduce the average cost per MWh locally produced;

> Manage a micro-grid network operating multiple power assets to maximize the use of the solar resource.

Coupled to weather forecast (SteadyMet), satellite imagery allows more accurate evaluation of cloud cover evolution and production profile over the coming hours. This module uses satellite images collected 1-4 times per hour. Through detailed modelling and advanced mathematical algorithms, energy production is predicted over the following hours with increased capability for assessing fluctuation risks and intermittency.
