In a word
So Flex’hy is the first virtual local hydro/intermittent-renewables power plant operated in real time.
The mass arrival of uncontrollable energy sources (solar and wind) onto the electrical grid can disrupt the essential balance between supply and demand. This gives rise to increasingly complex grid management and a greater need for flexibility and storage.
At the heart of the commune of Durance, in the Région Sud, the So Flex’hy project showcases the synergy between hydro, solar and wind renewable energy production. This virtual local plant harnesses the flexibility of hydroelectric reservoirs, which take over wind or solar energy production whenever clouds gather, or winds drop. The flexibility of hydropower is therefore supporting the integration of regional renewable energies by limiting grid overload and by contributing to a balanced power system.
These new income-generating services are opening new opportunities for hydropower. The project is easily transferrable to existing hydropower plants in France (and abroad) without resorting to substantial investment, through the implementation of a distance control platform such as the one developed by EDF Store & Forecast.
Why is this a game changer ?
- 40 times +
- Région Sud has set itself a target of rolling-out 40 times more solar power by 2050, relative to installed power as at end 2019.
- € 6M/yr
- Maximum saving for grid operators within the scope of the So Flex’hy project in the commune of Durance.
- 4,5 GW
- Of hydropower in France, the flexible nature of which can be further optimised by using a platform such as So Flex’hy.
