Steadysun supports EDT ENGIE to predict Tahiti solar farms power variability and avoid blackouts

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.
French Polynesia produces currently more than 35% of its electricity from renewable energies and aims to reach 75% in 2030. The issue of the solar energy variability, identified as a constraint in the energy transition, represents a management challenge in order to maximize the penetration of solar energy in the Tahitian grid.

Integration of a Large-scale Photovoltaic Power Plant into a Central American Network

As in all regions well exposed to the sun, photovoltaic energy is expanding in Central America. As it is the case here for this 60 MW plant, large-scale projects are currently being connected to the network. On January 22, 2018 sunny weather was forecasted by all the meteorological models used by our steadyMet solution.  None…

Trading : A Portfolio of Photovoltaic Solar Plants in Italy

If we consider the same prevision quality, the size and compositions of a portfolio have an impact on the gaps between planned and actual power generation. The case of September, 7th 2017 related to a portfolio of about 20 plants illustrates this point.  This is a rather chaotic day from a meteorological perspective. Here, the…

Solar Energy Forecasting Used to Manage a Solar PV Plant with Storage in an Insular Grid

In the Martinique Island (French oversea territory in the Caribbean), the grid stability can be seriously affected by the variability of the solar PV production. The larger-scale integration of this energy, will go with the addition of storage capacities and an adapted management system which integrates forecasts of the solar production over several time scales.…
