Current Tariffs and Change Process

Fuel Price Index Adjustment

As per the price notification from FSM Petroleum Corporation (below) the price of fuel to CPUC is currently USD$3.2724 per gallon, an increase of USD$0.1571 per gallon from the previous price of USD$3.1153 per gallon.

CPUC is therefore changing its power tariff to reflect the change in the fuel price as follows:

Consumer Category From Current Rate

(kwh)

To Current Rate

(kwh)

Increase
Residential
 
$0.4478 $0.4604 $0.0126
Commercial
 
$0.4778 $0.4904 $0.0126
Government
 
$0.4978 $0.5104 $0.0126

(Prices effective 20th October 2021 and shown in USD)

The new rate will apply until such time as the price of fuel changes.

CPUC would like to thank all customers for their continued support as we strive to provide a better, more convenient and reliable service.

 

Electricity Tariffs

CPUC’s electricity tariff is a totally variable tariff by customer type. There are no fixed charges, minimum charge, demand or capacity charges. The tariff is specified based on a cost of diesel to CPUC of $3.80 per gallon. The tariff is adjusted (approximately monthly) to reflect the actual cost of diesel.  Table 1 sets out CPUC’s base electricity tariff (assuming a cost of diesel of $3.80 per gallon) and the current tariff.

Table 1 – Electricity Supply Tariff Base

  Base Tariff Current Tariff (2021/09/15)
Residential $0.5026/kWh $0.4478/kWh
Commercial $0.5326/kWh $0.4778/kWh
Government $0.5526/kWh $0.4978/kWh

 

Almost all CPUC’s 2100 customers use a prepay system with a simple accumulation meter.  The system can charge fixed charges and rate block tariffs, but doesn’t have any smart or multi-register functionality (so, for example, day/night, peak/shoulder/off-peak or demand tariffs could not be implemented). There are also 61 larger commercial and government customers with post-pay accounts.
