CitiPower's network tariffs are regulated by Victoria's Essential Services Commission and reviewed in detail every five years. The most recent review was completed in 2005 and applies for the years 2006-2010 inclusive.
During this period CitiPower is operating under an incentive-based framework where average distribution tariff movements are based on a CPI-X formula. CPI represents annual inflation and X represents an efficiency allowance.
Table 1 presents the X factor for the period 2006 to 2010.

The sizeable X factor applied in 2006 represents efficiency savings delivered by CitiPower in the five years preceding 2006.
Movements in individual distribution tariffs are limited to CPI+2, where the maximum they can increase is by inflation plus 2%. This figure is adjusted for licence fees (L-Factor) and service quality (S-Factor).
