State Grid Jinhua Power Supply Company recently completed construction work at the 110-kilovolt Litian Substation in Jinhua, Zhejiang province, to support power line relocation for the Jinhua railway hub expansion and reconstruction project, the company said.

The work, carried out ahead of the summer electricity peak, is expected to strengthen local grid reliability and support the construction of key municipal infrastructure in Jinhua.

As high temperatures arrive and electricity demand rises, the company is making full use of the pre-summer construction window to accelerate a group of key urban power grid projects. The projects are designed to optimize the local grid structure, ease supply bottlenecks and improve the city's peak-load response capacity.

In 2026, the company plans to put 22 key grid projects of 110 kV and above into operation before the summer peak. Once completed, they will add 2.48 million kilovolt-amperes of transformer capacity and 192.2 kilometers of new power lines, according to the company.

So far, five projects have been completed and put into service, while the remaining 17 are being advanced under detailed schedules to ensure timely commissioning, it said.

Among the projects, the bay expansion project at the 220-kV Tangya Substation has entered operation, providing additional power capacity for industrial chains related to new energy vehicles and supporting local industrial upgrading.

The projects are expected to improve regional grid connectivity, reinforce weak links and strengthen load-carrying capacity, ensuring reliable power supply for residents and local industries during the summer peak, the company said.
