15 May How to get the most from your power bill
Are you getting the most from your power bill?
Sure, your power bill tells you what you need to pay, but it also gives you a wealth of other information if you know where to look.
Your cost of power depends on and is driven by the structure of the power system (fixed and variable costs), combined with the structure of the business (mostly regulated), that creates specific savings opportunities.

Charge determinants based on the facility’s peak demand, in the same hours when the system demand is at its peak, and during other non-peak and off-peak hours, create an opportunity to reduce costs by managing and reducing facility peaks, and by avoiding consumption during system peak periods.
For many businesses, better identifying and managing consumption around system peaks and around individual facility and portfolio peaks is the key driver of cost savings.
Every kilowatt of peak demand counts.
