Qinhuai Data Center Integrated Energy Station 110kV Substation Project
Project Background
The Qinhuai Data Center Integrated Energy Station 110kV Substation Project is located in Dananxinbao Village, Donghuayuan Town, Huailai County, Hebei Province. Developed by Hebei Qinhuai Data Co., Ltd., this substation serves the Qinhuai data center cluster and represents a key infrastructure component of China's strategic "East Data, West Computing" initiative — a national project to optimize data center distribution by relocating computing resources from eastern population centers to western regions with abundant renewable energy.
Challenges Faced
Mission-Critical Reliability Requirements
Data center operations demand the highest levels of electrical reliability:
Zero-tolerance for power interruptions that could affect thousands of servers and cloud services
Strict voltage stability requirements to protect sensitive IT equipment
Redundant power paths required to ensure continuous operation during maintenance or faults
Compliance with Tier III/IV data center standards for availability
Integration with Complex Energy Systems
As an "integrated energy station," the substation needed to interface with multiple energy sources:
Coordination with potential renewable energy inputs (solar, wind) feeding the data center
Backup power systems including diesel generators and UPS installations
Cooling system power demands requiring precise load management
Smart grid integration for demand response and peak shaving capabilities
Regulatory and Timeline Pressures
The project operated under significant external constraints:
Part of a national strategic initiative with visibility at the highest government levels
Multiple approval phases (pre-construction and post-approval public notices)
Coordination required across multiple stakeholders including grid operators, data center operators, and local authorities
Fixed construction timeline tied to broader data center rollout schedules
Customized Solution Highlights – 110kV/10kV Substation & Distribution System
Pushen Electric provided a comprehensive medium-voltage power distribution solution specifically engineered for the demanding requirements of hyperscale data center operations:
110kV/10kV Main Substation: A conventional indoor/outdoor 110kV substation designed to step down grid voltage to 10kV for distribution within the data center campus. The design incorporated N+1 redundancy configurations for critical components, ensuring no single point of failure could interrupt power supply to the data center loads.
Intelligent Protection & Automation System: Advanced relay protection and automation systems featuring microprocessor-based protection relays with communication capabilities for integration with the data center's building management system. Real-time monitoring of voltage, current, power quality, and equipment health enables predictive maintenance and rapid fault response.
Project Outcomes
Successful Regulatory Approval
The substation design successfully navigated the multi-phase approval process, receiving construction plan approval on May 9, 2026. The project's compliance with national standards and local planning requirements enabled smooth progression from design to construction phase.
Supporting National Computing Infrastructure
Upon completion, this substation will provide the reliable electrical foundation for the Qinhuai data center cluster — a critical node in China's "East Data, West Computing" initiative. The facility will enable the processing and storage of massive datasets while leveraging the region's favorable climate for natural cooling and access to renewable energy sources.
Model for Data Center Power Infrastructure
The project demonstrates how customized medium-voltage substation solutions can meet the unique demands of hyperscale data centers — combining high reliability, intelligent monitoring, and seamless integration with complex energy systems. The design approach and technical solutions developed for this project provide a template for similar facilities across China's expanding data center infrastructure.
