X. Confidential Information

SCE tendered testimony as part of its reasonableness application to substantiate the prudence of its contract administration, least-cost dispatch, and ERRA for the Record Period. Portions of SCE's data and testimony deemed commercially sensitive were tendered under seal, pursuant to General Order 66-C. Due to the commercially sensitive, confidential, and proprietary information on SCE's electric energy resources and its management of power resources to meet customers needs on a least-cost basis, all such information deemed commercially sensitive was placed under seal pursuant to a May 5, 2004 Administrative Law Judge (ALJ) ruling.

This information and subsequent associated information placed under seal relates to certain purchased power contract terms and costs, individual power prices, net position cost assumptions and other information that might put SCE at a competitive disadvantage, if revealed. Maintaining this information under seal is reasonable and consistent with the provisions of Pub. Util. Code § 454.5(g), which states the Commission shall adopt appropriate procedures to ensure the confidentiality of any market sensitive information submitted in an electrical corporation's proposed procurement plan. All such information placed under seal in this proceeding should remain sealed until the Commission issues a decision in Rulemaking 05-06-040 that establishes a consistent treatment of confidential procurement information for the major energy utilities. Upon the issuance of such a decision in the rulemaking proceeding, the sealed information shall confirm to the requirements of that decision.
