- Financing summary: El Dorado Energy was initially funded equally by Sempra Energy Resources and Reliant Energy Power Generation. In October 1998, the project obtained a $158 million senior-secured credit facility covering construction and 15-year term financing; Sempra reported $55 million invested by December 31, 1999, and a 2000 annual report described total project cost as $280 million. In July 2005, Sempra Generation acquired Reliant's remaining 50% interest for $132 million including assumed debt; the expected payment to Reliant net of project debt and closing adjustments was approximately $75 million. On October 1, 2011, SDG&E acquired El Dorado Energy LLC at approximately $214 million, based on member equity and the net balance of affiliate loans; a regulatory filing had estimated the purchase price at $215.1 million. — Sempra Energy 1999 Annual Report · confidence: medium

## Data quality

- Capacity figures vary by source and rating convention: later SDG&E and CAISO records identify a 480 MW nominal or maximum-net facility, with one CAISO record also stating a 492 MW nameplate rating, while an older Sempra annual report describes the plant as 500 MW. The cited history establishes operation through the ownership-transfer and interconnection records but does not establish a retirement, expansion, or repowering milestone.
