3. District-by-District Rate Setting  Currently, revenue requirements and rates are set and approved on a district-by-district basis. Many large water utilities have multiple districts. Many large water utilities have multiple districts. Individual districts within multi-district utilities have unique revenue requirements and tariffs. Individual districts within multi-district utilities have unique revenue requirements and tariffs. Some even have distinctly different rated within an individual district Some even have distinctly different rated within an individual district Factors than impact cost include infrastructure, geography, topography, and hydrology. Factors than impact cost include infrastructure, geography, topography, and hydrology.  Differs from Energy utilities, which set rates on a system wide basis.

4. High Cost Areas  District-by-district rate setting can result in: Large rate disparities between customers of the same utility; Large rate disparities between customers of the same utility; Create high cost areas that are unaffordable to many customers; Create high cost areas that are unaffordable to many customers; Create rateshock where the price increases by a large amount. Create rateshock where the price increases by a large amount.  In the past, the Commission has implicitly subsidized customers in higher cost areas. Subsidized by keeping their rates low while raising the rates to customers in lower cost areas. Subsidized by keeping their rates low while raising the rates to customers in lower cost areas. 1999 - Golden State Water Company consolidation of eight districts in Region III.

5. Multi-District Water Utilities

6. OIR to Consider Subsidizing High Cost Areas To advance its sixth objective of “setting rates that balance investment, conservation, and affordability”, the 2010 Water Action Plan listed actions items to consider, including: Development of policies to subsidize high cost areas. To do so, the OIR will consider: A “High Cost” fund mechanism, CPUC used similar approach for telecommunications ratepayers via the so-called High Cost Fund telecommunications. Consolidation of districts and rates within the multi-district water utilities. D.05-09-004 set forth a set of district rate consolidation guidelines that had been developed by in 1992 by DRA and the large water utilities. OIR will consider modifying the 1992 guidelines or establish new ones. *Proceeding will not adopt utility-specific “High-Cost” funds or order any water district consolidations. Mechanisms, if any are adopted, will be requested in each Utilities’ GRC.*

7. OIR will consider effects on Low- Income Customers  Seeks input from parties on whether the current water low-income assistance and rate support funds offered: are adequate to address ratepayer needs in general; are adequate to address ratepayer needs in general; whether these current mechanisms achieve an appropriate balance between utility investments, conservation and affordability of rates. whether these current mechanisms achieve an appropriate balance between utility investments, conservation and affordability of rates.
