Energy Management Energy Use: Energy Supply: & Building Set-up Supplier Operations Tariff Staff Schemes & Incentives Management Penalties
Reducing Supply Costs… 1. Electricity Consumption (kWh) Alternative suppliers � Alternative tariffs � Discounts for electronic billing � Night Saver � Consult your supplier
2. Maximum Import Capacity (KVA) 75 KVA * 62 days @ €0.072 = €334.80 20KVA * 62 days @ €0.072 = €89.28 Savings/ bill = €245
3. Standing Charges Fixed daily charge Covers the provision of electricity supply Charge applied to each bill not each premises � Consolidate separate bills
4. Wattless Charges Reactive Power Equipment such as motors, fluorescent lighting, No cost unless wattless units exceed one third of all day & night units per bill If charges persist, contact your electrical contractor or an energy consultant
Reducing Energy Use Consider how you use energy: Where is energy used By End use, Efficiency, Controls When is it used Load shift to cheaper night-time / weekend rate? Why is it used Infrequently used or redundant equipment
