Document Description
Poseidon Water (Poseidon) is the owner/operator of the Carlsbad Desalination Plant under contract to the Water Authority to deliver between 48,000 and 56,000 acre-feet per year (AFY) of drinking water from the CDP. On May 5, 2014, Cabrillo Power I LLC (Cabrillo) provided notice that the Encina Power Station (EPS), and the associated seawater intake pump, would be decommissioned, resulting in a permanent shutdown of the seawater intake pump that is currently used to circulate cooling water through the EPS, effective June 1, 2017. This action will require the CDP to transition to "permanent stand-alone" intake and discharge operation by this date. The intake and discharge facility modifications to enable "permanent stand-alone" operation comprise the "Proposed Project" for the purposes of a Supplement to the Precise Development Plan and Desalination.
