Main Text

The ISO and state energy agencies (CPUC and CEC) have prepared a draft Load & Resource Scenario Analysis Tool to aid in screening various load and resource scenarios for further reliability assessment in response to the Policy on the Use of Coastal and Estuarine Waters for Once through Cooling (OTC) power plants.  The tool, its description and a comment template are available on the ISO website at http://www.caiso.com/1c58/1c58e7a3257a0.html.  To help further refine this tool, stakeholders can use the template to submit comments by close of business July 30, 2010 to DLe@caiso.com.  The ISO is hosting a stakeholder conference call on August 13 to review the tool and respond to comments.

 

Background

On May 4, 2010 the State Water Resources Control Board adopted the Policy on the Use of Coastal and Estuarine Waters for Once through Cooling (OTC) power plants.  The Policy establishes technology-based standards to implement federal Clean Water Act section 316(b) and reduce the environmental effects associated with cooling water intake structures on marine and estuarine life. The Policy applies to the 19 existing power plants statewide, including 16 plants that are located in the California ISO’s Balancing Authority Area.  The policy does not go into effect until after it has been approved by the Office of Administrative Law (Gov. Code, § 11353, subd. (b)(5)).  The State Water Board will not file a California Environmental Quality Act Notice of Determination until after OAL makes its determination.  The plant owners have six months to submit implementation plans after the policy goes into effect.

 

The ISO has established a preliminary reliability assessment schedule in response to the Policy.  The 2010 near-term milestones are:

 

                  August 13               Stakeholder call to review the tool and discuss comments

                  September 3           ISO posting of finalized Load & Resource Scenario Analysis Tool

                  October 15              ISO posting of various tool-created scenario analyses
