Question 1 of 10
Alternative Generation & Storage
An ice-storage system will shift 150 kW of chiller demand off-peak in each of six summer months (demand charge $18/kW-month). It moves 200,000 kWh/yr of chiller energy from on-peak ($0.14/kWh) to off-peak ($0.07/kWh), but ice-making needs 15% more kWh than the chiller energy it replaces. Determine the annual cost savings.
