- Description: Great Valley Solar Portfolio Holdings, L is a 202.5 MW solar photovoltaic plant in Fresno County, California, with four operational generating units in the CAISO market and CISO balancing authority; RWE Clean Energy is the current operator. The California Public Utilities Commission describes the asset as a 200 MWAC portfolio of four facilities—Great Valley Solar 1 through 4—constructed on leased land. The first units entered service in December 2017, and full plant commercial operation commenced on April 14, 2018. Sempra originally developed and operated the project, sold it to Consolidated Edison in December 2018, and RWE became the successor corporate owner through its March 2023 acquisition of Con Edison Clean Energy Businesses. — Source · confidence: medium
- Quality notes: ["The EIA-derived record reports 202.5 MW across four units, while the CPUC audit describes the historical portfolio as 200 MWAC; this appears to reflect differing plant-label or capacity conventions rather than a documented expansion.","The $1.54 billion announced purchase price, approximately $1.6 billion completed-sale value, and $6.8 billion RWE enterprise value were portfolio or company-level transaction values, not plant-specific consideration for Great Valley Solar.","The disclosed 2018 financing covered four Sempra Great Valley solar farms collectively, so no plant-specific allocation of the more than $190 million financing or the $85 million tax-equity tranche is identified. Cited EIA data show four operational units, zero planned units, and no documented expansion, retirement, or repowering milestone."] — Source · confidence: medium

- Financing summary: In August 2018, Wells Fargo Renewable Energy and Environmental Finance completed the final $85 million of tax-equity funding for Sempra Renewables' 200 MW Great Valley facility; the release said this was the last phase of more than $190 million in financing for four Sempra Great Valley solar farms collectively. Separately, Consolidated Edison announced in September 2018 that its acquisition of Sempra's renewable portfolio had a $1.54 billion purchase price, included $576 million of existing project debt, and was expected to be financed with $715 million of equity and $825 million of long-term non-recourse debt. The completed December 2018 portfolio sale was approximately $1.6 billion in cash, while RWE's March 2023 acquisition of all Con Edison Clean Energy Businesses shares was based on a $6.8 billion enterprise value; neither amount is a plant-specific consideration. — Wells Fargo Completes Funding for 200-MW Sempra Great Valley Solar Project · confidence: medium
