SteadySat

Solar forecasts for the coming hours

ABOUT

Forecast based on satellite data for intraday solar forecasting needs

Combined with weather forecasts, satellite imagery allows the evolution of the cloud cover and the production profile to be refined for the coming hours. This module uses satellite images gathered up to 6 times per hour. Using fine modeling and artificial intelligence, the energy production for the coming hours is forecasted with better accuracy compared to the SteadyMet product to anticipate fluctuations and risks of intermittence in a more efficient way.

KEY BENEFITS

WORLDWIDE COVERAGE

Thanks to the combination of imageries coming from five geostationary satellites.

FAST AND EASY TO INSTALL

No material needed.

ACCURACY IMPROVEMENT

Compared to forecasts relying on meteorological models thanks to higher spatial resolution and update frequencies.

TAILORED OUTPUTS

In terms of update frequency, granularity and format.

CUSTOMERS NEEDS

This product is tailored to meet your solar business needs. It is particularly suitable for the optimization of storage dispatch and intraday trading markets.

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 OPERATORS


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

SMART CITIES


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

EPC & PLANT OPERATIONS


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

METHODOLOGY

SteadySat compiles live images from 5 geostationary satellites (step 1) and processes them (estimation of motion vector and application on the last available image) to estimate the clouds position for the next few hours. This cloud position is used to forecast the irradiance (step 2). The satellite imagery also allows us to estimate the global horizontal irradiance at acquisition time (10 to 15 minutes).

Forecasts 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.
