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

kWh 17% 58% 25% Lighting Electrical Heating & Cooling (31%) (24%) (45%)
