Xiashang Tianjin Ninghe Dongjituo 100MW Wind Farm

July 11, 2025

Overview

Xiashang Tianjin Ninghe Dongjituo 100MW Wind Farm, a key 2023 renewable project in Tianjin, operates 32×3.2MW turbines with annual output of 230 GWh. Located in Bohai Bay’s salt-fog zone (C4 corrosivity) and winter lows of -25°C, it complied with NB/T 10688-2021 for prefab substations. SH Power, as the sole enclosure supplier, delivered 35kV switchgear (incoming/collector cabinets) and prefabricated cabins, enabling full-capacity grid connection in June 2024—setting Tianjin’s record for fastest construction (11 months).
