Reuniwatt is a young and innovative French company settled in Reunion Island, a region recognized as one of the world's Renewable Energies laboratory.

This French start-up develops services for renewable energy operators. Its creativity and innovation were recently rewarded by several prizes (2013 "Creation-Development" award during the National Contest for Innovative Technologies, 2013 Tremplin PME INNOV'ECO prize, 2012 NETVA award, 2011 "Emerging" prize during the National Contest for Innovative Technologies) thanks to its unique solution for Photovoltaic Production Forecasting: Soleka.

Soleka is a decision-making tool, intended to ease the introduction of renewable energies in the energy mix as it will enable to forecast the production of solar power plants at three time scales:
• 1 day ahead forecasting in order to convey to the distribution network operators the next day’s production capacity enabling them to plan their means of production.
• 4 hours ahead, or intra-day forecasting which allows the photovoltaic electricity storage operators to confirm or invalidate their production commitments without risking penalties.
• 30 minutes ahead, or shortcasting which enables the electricity suppliers to securely provide their energy and to optimize their means of production inside the grid.

Soleka is a solution that can be used by all the smart-grid key stakeholders (TSOs, DSOs, energy suppliers, power system and component manufacturers, electricity service providers, grid regulators...).
