SteadyMet

Solar forecasts for the coming days

ABOUT

Forecasts based on meteorological models for day-ahead solar forecasting needs

SteadyMet provides day-ahead solar forecasts up to the next 15 days. The product optimally combines several meteorological models and optimizes their output by leveraging measurement data from solar plants and by using artificial intelligence technologies.

Among the Numerical Weather Prediction (NWP) used by SteadyMet, it is worth highlighting the use of the Weather Research and Forecasting (WRF) model. It is a free regional meteorological model that can be configured at very high resolution, thus providing highly accurate forecasts at local levels.

Forecast D+3, over the whole of Germany for TSO and traders

36 hours Forecast, for a region in Italy (1,450MW)

METHODOLOGY

SteadyMet is based on an optimal combination of several Numerical Weather Prediction (NWP) models. These models simulate the evolution of the atmosphere (step 2) from initial atmospheric conditions estimated by assimilation of meteorological observation data over a global or local granularity (step 1). For this purpose, the area of ​​calculation is divided into a three-dimensional grid with more or less large mesh. 

Weather model’s outputs of interest (solar radiation, temperature, wind, etc.) are then optimized (step 3), by using production/irradiance observations, to take into account local phenomena, and by leveraging artificial intelligence technologies.

Ready-to-use forecasts, in a customized format, are then disseminated (step 4) through our proprietary web interface, csv files delivered via (S)FTP platforms or API.
