Estimated Retail Impact of Carlsbad Desalination if Applied to CY 2013 Rates (below analysis done in October 2012, prior to closing):
Estimated rate impact as Water Authority supplies:o Based on high range of Carlsbad seawater desalination costso Based on conservative 2013 sales of 466,000 AF
• First year of operation sales (2016) projected at 520,000 AFo 5 Retail Agency Average Composite Cost (CY 2012)
• Fixed Charge $19.83 + Commodity Charge $51.40 = Composite Monthly Bill: $71.23
Other Water Authority Notes:
1. Analysis based on retail rates for the City of Carlsbad, Helix Water District, the City of San Diego, Sweetwater Authority, and Otay Water District.
2. Tier 1 and Tier 2 pricing blocks vary by member agency.
3. Historic total water demand used to calculate member agency specific weighting factors.
4. Individual member agency commodity charge calculated using its average single family residential water use (hcf).
5. Composite commodity charge is the sum of the individual member agency's commodity charge times its weighting factor.
Estimated All-in Unit Cost(48,000 – 56,000 AF/yr)*
Estimated Rate ImpactMonthly Retail Cost Percent Retail Impact
$2,290 - $2,041 $7 - $5 10% - 7%* Includes both direct costs billed by Poseidon and indirect costs incurred by the Water Authority outside of the agreement with Poseidon. Actual rate impact will vary by member agency.
