L'ONS réduit pour la première fois la production des petites centrales de 1 GW

L'opérateur national du réseau a ordonné dimanche une réduction de 1 GW auprès des petits générateurs après avoir déjà diminué la production des grandes centrales.

L'ONS a activé son plan de réduction d'urgence dimanche (7), limitant la production de 10h à 14h pour les centrales de plus de 5 MW. La mesure a atteint 1 GW, soit l'équivalent de la consommation d'environ 500 000 foyers, et marque la première fois que l'opérateur suspend les petits générateurs. Dans le Nord-Est, les coupures ont atteint 11 GW dimanche et 15 GW samedi. La capacité de micro et mini-génération distribuée dépasse déjà les 44 GW à l'échelle nationale, augmentant les risques de surcharge lors des journées à faible demande. Les associations du secteur réclament des mesures incitatives pour le stockage via des batteries et des tarifs variables selon l'heure. L'Aneel a autorisé la suspension des petites centrales en 2025 après les avertissements de l'ONS concernant les risques pour le système.
