Tianjin Electric Power Construction – Heze 1000 kV Substation Project（96 units）

Project Overview

This project is part of a national key power infrastructure development—a 1000 kV UHV substation—with extremely high requirements for construction quality, delivery speed, and site image.

A total of 96 modular container building units were deployed to build an integrated modern office complex, including office areas, meeting rooms, and management spaces to support the entire project lifecycle.

With tight timelines and complex conditions, this project represents not just a temporary facility, but a comprehensive test of the contractor’s execution capabilities.

Location

The project is located in Heze City, Shandong Province, China, a key energy hub in East China, playing a vital role in regional power transmission and distribution.
