Short-term forecasting

Unlike conventional energy plants, the output of a renewable power plant is as changeable as the weather. A wind farm can’t generate energy without a breeze, while cloud cover impacts a solar power plant’s generating capability.

Accurately anticipating weather conditions ensures plant owners and operators get the most out of their facilities. System operators need to know how much energy a renewable plant can deliver and traders strive to get the best price for every megawatt hour.

Predicting renewable energy production
Previously known as GH Forecaster, DNV GL's Short-term energy forecasting service is vital for effective management of your renewable assets. It provides accurate, up-to-date predictions of energy generation through in-depth, site-specific weather forecasting and our unparalleled understanding of renewable energy systems. 

Our highly skilled and diversely experienced team makes use of base weather data from the world's top weather models, downscaling and localizing them to produce the most accurate forecasts for your particular power plant. Through detailed analysis and computation, we then calculate the predicted energy output taking into account the number of machines at your site. Forecasts can be provided for any location across the globe.
