BEIJING, June 6 (Xinhua) -- The expanded Tianjin South 1,000 kV ultra high voltage (UHV) substation in north China's Tianjin Municipality was put into operation on June 4.
As a pivotal hub of the North China Grid under State Grid, this substation is tasked with allocating clean energy across the Beijing-Tianjin-Hebei-Shandong region. Following an 18-months expansion, its power transmission capacity has doubled, enabling Tianjin's capability of receiving electricity from external sources to over 40 billion kWh annually. This upgrade injects strong momentum into regional energy structure transformation and the realization of China's dual carbon goals.
The substation expansion project, an important initiative under China's 14th Five-Year Plan for power sector development, commenced in December 2023. It involved installing two new 3,000 MVA main transformers, and boosting substation land-use efficiency by 30 percent while enhancing intelligent upgrading of facilities.
State Grid Tianjin Electric Power Company plans to leverage the Tianjin South 1,000 kV UHV substation as a benchmark for accelerating development of the Tianjin North 1,000 kV UHV substation. This effort will support the broader ambition of expediting the establishment of the Beijing-Tianjin-Hebei UHV transmission network, so as to promote regional coordinated development and accelerate the region's progress toward carbon peak goals.
To date, over one third of Tianjin's electricity supply originates from external sources, with green power constituting 35 percent of this external supply.
