The world’s first agrivoltaïc power plant
Located in the western Pyrenes, the Nidolères estate has been a family-owned wine-growing estate for 8 generations with a vineyard spreading over 32 Ha.
The Escudié family uses sustainable agriculture methods i.e. a reduced use of pesticides.
The agrivoltaic system has been built over new vines located on a former 7,5 Ha wine paddock which was disused in 1992 and was never replanted again due to a lack of satisfactory solution.
Wine-growing region enjoying a dedicated Protection Designations of Origin (PDO) since 2017. The region produces excellent wines despite low yield: <40hl/Ha. The vineyards are directly threatened due to climate changes and increasingly severe droughts to the point where the decline of farm land is the highest in the region.
Climate change most identified effects are
- Early maturity of grapes:
– Increase of sugar levels and therefore of alcohol level
– Development of flavor precursors and therefore modification of the taste of wine
– Drop of wine acidity
- Increased need of water in a context where, due to less efficient precipitations, there is a need for irrigation systems,
- Increased temperatures and sunshine modify the balance of flavors in wine.
Objectives Of Agrivoltaism For The Nidolères Estate
- Boost the vineyard,
- Produce more acidic and better balanced white and red wines,
- Multiply by two the value of wine under agrivoltaic systems thanks to improved quality and a controlled alcohol level,
- Consolidate the estate by restoring profitability and by making it more resilient to climate changes in order to pass it on to the next Escudié generation.

Height of the agricultural structure
– 20% reduction in water consumption on the plot,
– Improvement of organoleptic qualities: +13% anthocyanins and between 9 and 14% acidity,
– During the heat waves of summer 2019, a decrease in growth arrest, a reduction in leaf burns.
