2 x Residential Lifts and fluorescent utility lighting operating as “inductive loads” with a resultant power factor in the order of 0.72 - this is bad!

A 75 KVAr Power Factor Correction (PFC) unit was installed to correct the load. This resulted in a power factor of approximately 0.99 - this is really good!

Daily demand reduced by approximately 25%, with an immediate reduction in electricity costs of approximately $2,000 per year

Cost: $4,000

Payback: 24 months

This is but one of several initiatives undertaken by Nexus over a 12-month period.
