China continues to amaze the world with the pace of deploying advanced technologies in critical infrastructure. In the city of Hefei, the administrative center of Anhui Province, the country's first demonstration electrical substation, built entirely around quantum solutions, has begun operation. The Houdian facility, designed for 220 kV voltage, was commissioned back in November 2024, but only now have the impressive details of its technical equipment become known.

This is not just a pilot project, but a full-fledged technology testing ground. The substation integrates 85 in-house developed quantum devices, divided into 18 categories. They cover three key areas: ultra-precise sensing, secure communication channels, and high-performance computing.

Houdian's Technological Arsenal

Engineers applied a comprehensive approach to address the problems faced by traditional power grids. Here are the main components of the system:

  • Diamond quantum sensors — provide monitoring of current fluctuations with unprecedented accuracy.
  • Quantum dot sensors — continuously analyze the gas environment in control cabinets, identifying risks of cable fires and partial discharges at an early stage.
  • Quantum lidar — scans the atmosphere within a 15-kilometer radius, forecasting weather risks for power lines.
  • Quantum position sensors — detect changes in the magnetic field at a level of 1/10,000 of Earth's indicator, allowing control over the alignment of power line supports.
  • Quantum cryptography — all data exchange is protected by fiber-optic quantum communication and 5G+ quantum standard encryption, making interception of facility control virtually impossible.
  • Quantum computing — power flow calculations are performed by the Origin Wukong quantum computer, paving the way for real-time modeling of large-scale power grids.

The implementation of such technologies is not a tribute to fashion, but a harsh necessity. Modern grids, overloaded with renewable energy and complex power electronics, can no longer cope with the load. They lack monitoring accuracy, response speed, and security levels. As noted by Tian Teng, an engineer at the Digitalization Institute of State Grid Anhui Electric Power, the new system detects equipment defects much faster, reducing operating costs.

The results are impressive: over a year of operation, the error in electricity measurement was reduced by more than 500,000 kWh. This is not just a number — it is proof that quantum technologies are moving from laboratories into the real sector of the economy.

My view: This project is an important signal for the entire industry. China is not just experimenting, but creating a benchmark standard for modernizing energy systems. Houdian's success could accelerate the global race for quantum superiority in infrastructure sectors, where the stakes are immeasurably higher than in the financial sector.
