Solar and wind power plant forecasting

Weather forecasting for solar and wind power plant operations is crucial for many stakeholders involved in renewable energy.

Power plant operators and producers need to accurately forecast the volume of energy their plants will produce in the coming minutes, hours and days, in order to sell the electricity produced to grid managers.

Increase economic benefits

Accurate power forecasts lead to reduced imbalance charges and penalties. Therefore, wind and solar forecasting for plant operations gives a good visibility regarding the resources that will be available in the next minutes, hours and days.

Integrate more variable energy sources

Integrating forecasting into the process of committing generation units helps operators moderate the uncertainty linked to wind and solar power generation.

Improve system reliability

Scheduling and planning using forecasting help avoid costs and the lack of efficiency due to unnecessary starts and stops of diesel and thermal generators.

Power forecasting for innovative solar and wind installations

Solar and wind energy production forecasts

Forecasting is essential for innovative utility-scale solar and wind power projects to optimize grid integration and stability. Accurate weather predictions are crucial for onshore and offshore wind farms. Bifacial PV modules, capturing sunlight on both sides, benefit from precise forecasts to maximize efficiency. Moreover, floating PV systems on water also need accurate forecasts to enhance performance. Trackers for PV modules require reliable predictions to follow the sun effectively. Furthermore, solar thermal power plants and CSP systems depend on accurate forecasting for managing thermal storage and power generation.
