SteadyMet

Solar forecasts for the coming days

ABOUT

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

SteadyMet provides weather and solar production forecasts up to 15 days ahead. This product combines several sources of Numerical Weather Predictions (NWP) data with physical models and artificial intelligence.

SteadyMet can be configured at very high resolution using the Weather Research and Forecasting (WRF) model, providing highly accurate forecasts at local scale. Steadysun is able to implement and optimize this model anywhere in the world to meet the need of high-quality day-ahead forecasts.

KEY BENEFITS

WORLDWIDE COVERAGE

Thanks to a large number of global and regional NWP data from several weather services.

BEST-IN-CLASS SOLUTION

An approach combining ensemble predictions from the leading weather models, real-time on-site measurements and cutting-edge technologies to offer accurate probabilistic forecasts.

RELEVANT FOR MICROCLIMATES

An in-house regional model at very high spatio-temporel resolution, providing realistic and precise forecasts in areas where local effects are significant and public regional weather models are not available

TAILORED OUTPUTS

In terms of weather parameters, update frequency, granularity and format.

CUSTOMERS NEEDS

Our solutions are tailored to meet your solar business needs.

Renewable energy trading & Portfolio management


Solar and wind portfolio production forecasts to sell electricity at the best price on energy market (SPOT), and to minimize the cost of imbalance penalties.

GRID MANAGEMENT


Solar and wind forecasts to reduce spinning reserve, and avoid grid instability.

SMART GRIDS & SMART CITIES


Solar, Wind and Load forecast to define the best control strategy and maximize self-consumption.

PLANT OPERATIONS


Products and services for solar plant operators allowing you to maximize the profitability of your plants.

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.
