However , with these newer SiC-based solutions , there ’ s no need for such a ‘ smoke and mirrors ’ approach , as you know the 98.1 % figure is in true online mode .
Proof of significant savings
As you ’ d expect , ultra-high efficiency modular UPS such as Multi Power2 deliver cost , energy and carbon emissions savings when replacing old legacy monolithic UPS systems . But they also significantly outperform the currently available standard modular solutions too .
What follows are two actual TCO calculations provided to data centres in the process of upgrading their UPS . Comparison 1 outlines the savings as a result of replacing a monolithic 1MW N + 1 UPS system ( made up of 3 x 12 pulse 600kVA 0.9pf UPS ) with a 1,250kW Multi Power2 .
• Total annual energy cost saving = £ 95,759.65
• Overall total annual cost saving = £ 117,544.13
• Total annual CO 2 saving
= 148.7 tonnes
• Total 15-year cost saving = £ 2,353,655.21
• Total 15-year CO 2 saving
= 1702.8 tonnes
While Comparison 2 highlights the savings delivered by a 1,250kW Multi Power2 at 1MW load versus another manufacturer ’ s latest modular offering , with their system comprising 3 x 400kVA modular units .
• Total annual energy cost saving = £ 51,099.24
• Overall total annual cost saving = £ 53,839.91
• Total annual CO 2 saving
= 79.4 tonnes
• Total 15-year cost saving = £ 1,078,068.22
• Total 15-year CO 2 saving
= 908.7 tonnes
In addition to these substantial topline costs and carbon savings , SiC-based UPS offer data centre operators other benefits . In a traditional UPS , capacitors usually need replacing between service life years 5 – 7 , so over a typical 15- year lifespan you might be looking at swapping them out two or potentially three times .
However , the life-long components used in Multi Power2 mean it is realistic to go through the entire product lifespan without replacing the capacitors at all , a significant cost saving plus fewer end-of-life components that require recycling .
All in all , a typical data centre could save around £ 80,000 –£ 120,000 in maintenance costs over the lifespan of the UPS . This figure doesn ’ t even consider additional knock-on environmental benefits such as reducing the number of miles engineers will travel because of fewer required maintenance visits . �
