EDT ENGIE is deploying a Steadysun solar energy forecasting solution on the Tahiti island to predict solar variability in the very short term (30 minutes) and then enable to ensure the island’s power network stability.

The project consists in installing a network of eight sky imagers that will acquire local cloud information by taking hemispherical pictures at a high frequency (up to 15 seconds). Each sky imager is equipped with a pyranometer measuring the solar irradiance as well as a temperature sensor. The combination of the images and the local weather measurements are processed in our SteadyEye cutting-edge forecasting service.

Used in conjunction with our forecasting products SteadySat and SteadyMet, this solution will enable to forecast the state of the cloud cover for the very short-term, along with the solar plants production. This will allow for the grid operator to anticipate coming PV production drops and then compensate by switching on a thermal unit to guarantee the power grid stability.
