Data Center Decommissioning: How to Sell Electrical Equipment

2024-08-20 · 10 min read · Data Centers

A guide for data center operators on maximizing the value of electrical equipment during decommissioning — transformers, UPS, switchgear, PDUs, and generators.

The Data Center Decommissioning Opportunity

Data center decommissioning has become increasingly common as companies migrate to cloud services, consolidate facilities, or upgrade to newer infrastructure. When a data center is decommissioned, the electrical infrastructure — which often represents 30-40% of the original construction cost — can be sold on the surplus market for significant returns.

A typical 5 MW data center contains $2-5 million worth of electrical equipment at replacement cost. Even at surplus market prices, this equipment can generate $400,000 to $1.5 million in recovery value — money that would otherwise be lost to scrap or demolition.

Electrical Equipment Found in Data Centers

Transformers

Data centers typically have multiple transformers:

Utility transformers (2,500 - 10,000 KVA) — Step down utility voltage to building distribution voltage
UPS input/output transformers (500 - 3,000 KVA) — Isolate and condition power for UPS systems
PDU transformers (75 - 500 KVA) — Step down voltage for server rack distribution

Typical value: $5,000 - $75,000 per transformer depending on size and condition

Uninterruptible Power Supplies (UPS)

UPS systems are among the most valuable equipment in a data center:

Static UPS (200 - 2,000 KVA) — Eaton, Vertiv/Liebert, Schneider/APC, Mitsubishi
Rotary UPS (500 - 3,000 KVA) — Hitec, Piller, Hitzinger

Typical value: $10,000 - $150,000 per unit depending on manufacturer, capacity, and age

Switchgear and Switchboards

Main switchgear — 480V or medium-voltage main distribution
Automatic transfer switches (ATS) — Critical for redundancy
Static transfer switches (STS) — High-speed transfer between power sources
Paralleling switchgear — For generator paralleling

Typical value: $5,000 - $100,000+ per assembly

Power Distribution Units (PDUs)

Floor-standing PDUs — Large units that distribute power to rows of racks
Rack-mount PDUs — Smaller units mounted in server racks
Remote power panels (RPPs) — Branch circuit distribution

Typical value: $1,000 - $25,000 per floor-standing PDU

Generators

Diesel generators (500 - 3,000 KW) — Caterpillar, Cummins, MTU
Natural gas generators — Less common but growing in data centers

Typical value: $20,000 - $300,000+ per generator depending on size and hours

Cooling Infrastructure

While not strictly electrical, cooling equipment has significant value:

Chillers (200 - 2,000 tons)
CRAC/CRAH units
Cooling towers

Maximizing Recovery Value

Start Planning Early

The biggest mistake in data center decommissioning is waiting too long to engage equipment buyers. Ideally, contact buyers 3-6 months before decommissioning begins. This allows time for:

Detailed inventory and assessment
Market research for optimal pricing
Coordinated removal scheduling
Proper testing while equipment is still energized

Keep Equipment Energized

Equipment that can be demonstrated as operational commands 20-40% higher prices than de-energized equipment that cannot be tested. If possible, keep electrical systems energized until the buyer can perform testing.

Maintain Documentation

Gather and organize:

Original equipment specifications
Maintenance records
Test reports
One-line diagrams
As-built drawings

Sell Complete Systems

A complete UPS system (UPS + batteries + bypass + transformer) is worth more than individual components sold separately. Similarly, complete switchgear lineups command premium prices.

Consider Timing

The data center equipment market fluctuates based on supply and demand. If multiple large decommissioning projects hit the market simultaneously, prices can drop. Your buyer can advise on optimal timing.

The Removal Process for Data Centers

Data center equipment removal requires specialized expertise:

Phase 1: Assessment (1-2 weeks)

Detailed inventory of all equipment
Access route planning
Rigging requirements assessment
Scheduling coordination

Phase 2: Preparation (1-2 weeks)

Equipment de-energization
Disconnection of all utilities
Removal of obstacles and access preparation

Phase 3: Removal (2-6 weeks)

Systematic removal starting with smallest/lightest items
Heavy equipment removal (transformers, generators, switchgear)
Loading and transportation
Site cleanup

Safety Considerations

Data center electrical equipment operates at lethal voltages. Professional removal requires:

Licensed electricians for disconnection
Certified riggers for heavy lifts
Proper lockout/tagout procedures
Arc flash protection
Confined space protocols (for some equipment locations)
