What is DEMAND?
Highest amount of electricity used during a specified interval – “peak load”
Measured in kw (kwh/hour)
Charged for highest in billing period
Why Charge for Demand?
Accounts for time-varying nature of customer loads (loads are not constant)
Higher demand requires larger utility facilities – wire, transformers, etc.
Allocates fixed costs fairly among customers
Rate Components
Distribution Charge
Transition Charge
Transmission Charge
Generation Charge
Shopping
With deregulation customers may buy their supply (Transmission & Generation) from a third party provider.
For a customer to reduce their bill their supplier’s cost must be less than the utility’s Price to Compare.
Price to Compare = Transmission kwh charge + Generation kwh charge
For Rate GS Medium, Price to Compare = $.01252 + .04869 = $.06121
Energy Conservation
&
Load Management
Energy conservation is reducing the amount of kwh you use (turning off lights)
Load management is reducing your demand (reducing equipment wattage, rescheduling uses)
For every 100 kwh reduced you save
100 x $0.06178 = $6.18
For every 1 kw reduced you save $6.96
