Energy Price Adjustment
Energy Price Adjustment (monthly-billed tariffs only)
Each month an adjustment is made to the bill to reflect changes in the price of 'wholesale' electricity in the all-island Single Electricity Market. Wholesale prices are affected by the price of fuel used in the power stations, supply and demand, currency exchange rates, availability of transmission lines etc.
The EPA adjustment is based on the number of units of electricity used (kWh). It can either be a credit or a debit and thereby provides an element of protection for both parties from excessive, unexpected price swings. Each supply is placed into one of the following EPA categories:
- Small Medium Voltage (SMV) - annual consumption less than 150,000 units
- Large Medium Voltage (LMV) - annual consumption equal to or greater than 150,000 units
- High Voltage (HV) - all customers supplied at high voltage (in excess of 650 volts)

NOTES
- EPA applies to monthly-billed tariffs only.
- In the absence of accurate consumption history, medium voltage supplies with a Maximum Import Capacity of less than 100kVA will be deemed SMV.
- The EPA category for each supply will be reviewed annually on 1 October.
