Electrical ProposalElectrical Proposal

Electrical Proposal: Existing Electrical Proposal: Existing System OverviewSystem Overview

• Radial system to distribute power from the utility

• 13.2 KV stepped down to 480/277V by (2) 2500kVA transformers by CNBC owned substation unit

• Transformers feed a 4000A switchboard in the basement of the CNBC building

• Backed by generator set of (2) 2,000 kW, 480Y/277V each

• Technical equipment backed by (2) power-tied 1000kVA static UPS with 13 minute battery back-up

Electrical Proposal:Electrical Proposal:

• Compare reliability between a static UPS and a rotary UPS

• Add another 2000kW Generator to pick up load dropped by pre-programmed ATSs

Electrical Proposal: UPS Electrical Proposal: UPS Reliability Study (Static vs. Reliability Study (Static vs.

Rotary)Rotary)• Performance analysis

• Reliability• Maintenance

• Impact on mechanical loads

• Cooling• Exhaust

• Cost Comparison

Electrical Proposal: Electrical Proposal: Generator AdditionGenerator Addition

• Original Design Intent: • (2) Paralleling 2000kW generators, where (1)

2000kW can carry full load of the building

• Actual Power Consumption: • 2,964 kW (From Energy Utility Data)• Results in almost 1000kW of load to be

dropped by ATSs

• Solution: • Add a third generator to pick up the loads

dropped
