Reuniwatt is excited to announce its participation in the World Future Energy Summit (WFES) 2025 in Abu Dhabi, where the focus will be on the critical importance of solar and wind forecasts for utility-scale projects. Committing to Wind and Solar The United Arab Emirates (UAE) is making significant strides in renewable energy, with ambitious goals set to double its clean energy capacity as part
Under the sun of Reunion Island, a small tech startup named Reuniwatt was born fifteen years ago, driven by a vision to harness the power of solar energy and mitigate the dependency on fossil fuels. Reuniwatt was founded during a period when the population was growing and energy consumption on the island was escalating rapidly. The island had set ambitious goals for renewable energy,
Forecasts allow grid operators to take pre-emptive actions to maintain stability, especially during rapid changes in renewable generation or significant weather events. Wind and solar forecasts play a crucial role in the effective operation and management of wind and solar farms. By forecasting wind speed, direction and patterns, Reuniwatt helps the operators to anticipate the wind farm’s power output, aiding in efficient energy planning
