Nanjing – Resilient Infrastructure in Eastern China
Executive Summary
Nanjing is a strategic Tier 2 data center market for businesses requiring low-latency access to the massive Yangtze River Delta economic region. While not a primary interconnection hub, it provides a solid and often more cost-effective alternative to Shanghai for disaster recovery and regional application delivery. This market is ideal for companies prioritizing resilient infrastructure and proximity to one of China's core industrial and technological zones.
Nanjing: At A Glance
| Factor | Rating / Data | Notes |
|---|---|---|
| Global Connectivity Grade | B | Strong national and regional connectivity, but fewer international links than primary hubs. |
| Direct Cloud On-Ramps | 0 – as of September 2025 | Access is via private network extension to the primary hub in Shanghai. |
| Power Cost | US$0.08/kWh – as of Q2 2025 | Competitive pricing for a major industrial region, supporting cost-effective operations. |
| Disaster Risk | Low (3.0/10) – as of September 2025 | Primary risks are river flooding and cyclones, requiring standard facility-level mitigation. |
| Tax Incentives | No – as of September 2025 | The market does not currently offer specific tax subsidies for data centers. |
| Sales Tax | 13% VAT (standard rate) – as of September 2025 | Some goods and services may qualify for reduced rates of 9% or 6%. |
Network & Connectivity Ecosystem
Nanjing’s connectivity ecosystem is focused on serving the domestic market with high-capacity national backbones. It is a secondary market that relies on primary hubs like Shanghai for international and direct cloud access.
Carrier Density & Carrier Neutrality The market features 4 data centers from a single provider, as of September 2025. This indicates a concentrated market structure, with network diversity primarily available through major state-owned carriers. True carrier neutrality is limited, and most facilities are built-to-suit or anchored by a primary network provider.
Direct Cloud On-Ramps There are no direct cloud on-ramps within Nanjing's data centers, as of September 2025. All major public clouds, including AWS, Google Cloud (GCP), Microsoft Azure, and Alibaba Cloud, are accessed via dedicated network connections to facilities in Shanghai. Private network interconnects and wavelength services are the standard methods for achieving secure, low-latency hybrid cloud architectures.
Internet Exchange Points (IXPs) Public peering is not a significant feature of the Nanjing market. The majority of traffic exchange occurs privately between carriers or is routed through national exchanges located in major hubs like Beijing, Shanghai, and Guangzhou.
Bare Metal Bare metal server options are available in the region, typically provisioned from facilities in Shanghai to serve the broader Eastern China market. Providers such as Hivelocity offer dedicated server solutions that can connect back to infrastructure located in Nanjing.
Power Analysis
Average Cost Of Power The industrial electricity rate in Nanjing is approximately US$0.08/kWh, as of Q2 2025. This competitive power cost, combined with a stable grid, makes it an attractive location for workloads that are power-intensive but do not require the interconnection density of a Tier 1 market. The national energy mix is dominated by fossil fuels (~65%), with a growing share from renewables (~30%) and nuclear (~5%).
Power Grid Reliability As a major provincial capital and economic center, Nanjing benefits from a well-engineered and reliable power grid. Data centers are typically served by redundant power feeds from multiple substations, ensuring high levels of uptime for mission-critical operations.
Market Access, Business & Tax Climate
Proximity To Key Business Districts Nanjing's data centers serve a thriving local economy focused on electronics, petrochemicals, and automotive manufacturing. The city is also home to numerous universities and research institutions, driving demand for high-performance computing and data storage. Proximity allows these industries to leverage colocation for their core IT needs.
Regional Market Reach Located strategically within the Yangtze River Delta, Nanjing provides low-latency connectivity to over 150 million people. It is an effective point of presence for serving the populations of Jiangsu, Zhejiang, and Anhui provinces, making it a critical hub for content delivery and regional service platforms.
Tax Advantage For Data Centers There are no specific tax incentives for data center construction or operation in Nanjing. The primary financial advantage stems from lower operational costs, particularly for power and real estate, compared to nearby Shanghai.
Natural Disaster Risk
Nanjing has a low overall risk profile for natural disasters, with an INFORM Risk score of 3.0 out of 10, as of September 2025. While the overall threat is minimal, operators must plan for specific, high-impact regional hazards.
The most significant environmental risks include:
- River Flood: The city's location on the Yangtze River presents a notable risk of flooding, requiring careful site selection away from floodplains.
- Tropical Cyclone: Nanjing can be affected by the remnants of typhoons during the summer months, bringing high winds and heavy rainfall.
- Earthquake: The region has moderate seismic risk, making adherence to earthquake-resistant building codes essential for data center construction.
