Santa Catalina Water System
General Rate Case


On November 15, 2010 Southern California Edison (Edison) requested the CPUC for a rate increase of $3.2 million or 80%, resulting in a total revenue requirement of $7.2 million, for its Santa Catalina Island Water System customers for upgrades to its aging water infrastructure. On April 23, 2012, the CPUC issued a proposed decision that 1) decreased the revenue requirement increase from Edison’s requested 80% to 45% 2) shifted costs to Edison’s electric customers, and 3) maintains service rates at present levels.

In April 2012, the CPUC issued a Proposed Decision decreasing Edison's revenue increase request and proposing that the upgrade costs for Santa Catalina's water system be shifted to Edison's electric ratepayers.

In August 2012, the CPUC issued a Ruling suspending the proceeding to allow parties to settle issues of dispute.

The Public Advocates Office Position

On May 14, 2012, the Public Advocates Office submitted comments in response to the CPUC’s Proposed Decision stating that it:

  • Supports the PD’s decrease in revenue requirement increase.
  • Opposes the PD’s solution to shift costs to Edison’s electric customers who receive no benefit of improvements made to Catalina’s water service (additionally, Edison electric customers have received no appropriate notice of proposed rate increases as required by the CPUC).
  • Recommends the CPUC spread the rate increase over a 3-year period to mitigate rate shock to Catalina customers.
