- Description: West Deptford Energy Station is a roughly 751-MW natural-gas-fired combined-cycle facility in Gloucester County, New Jersey, with EIA generator records E101, E102, and STG1 and the PJM node ACE-W-DEPTFORD-1-CC. EIA records show first operation in October 2014, while project sources identify commercial operation in November 2014 and service to northeastern PJM. LS Power developed and operated the project; an LS Power affiliate sold equity interests in September 2016 to Marubeni, Sumitomo, and other partners. In early 2025, LS Power acquired a combined 67.7% Class A interest from five previous shareholders, simplifying ownership to LS Power at 85.5% and Ullico at 14.5%. — West Deptford Energy Holdings LLC Senior Secured | S&P Global Ratings · confidence: medium
- Quality notes: ["Reported capacity varies by measurement basis: LS Power reported 738 MW nominal at the 2011 financing stage, the 2016 ownership announcement reported 751 MW, and the EIA generator records list 225.3 MW for E101, 225.3 MW for E102, and 304 MW for STG1, totaling 754.6 MW of nameplate capacity.","The 2016 sources identify a 10% interest acquired by Sumitomo, while Perennial Power separately describes a 10% 2016 acquisition; these may represent the same investment and should not be counted as two separate 10% interests without additional documentation.","The early-2025 ownership consolidation is dated only to early 2025 in the available rating source; the exact closing month and the identities of the five selling shareholders were not disclosed there. Sale consideration for the 2016 equity transaction was also not reported in the cited announcement."] — LS Power Completes Financing for West Deptford Energy Station - LS Power · confidence: medium
- Financing summary: West Deptford Energy Holdings completed construction financing on 2011-11-30, but the LS Power announcement did not disclose the financing amount or lender names. S&P described a 2019 refinancing comprising a proposed $445 million senior secured Term Loan B due 2026 and a $55 million senior secured revolving facility due 2024; proceeds were intended to refinance an existing $347 million term loan, fund a $90 million sponsor distribution, and pay transaction expenses. In 2025, S&P described a proposed $255 million Term Loan B due 2032 and a $50 million revolving facility due 2030, supported by a $191 million sponsor cash contribution to repay approximately $441 million of existing debt, plus $6 million of transaction fees and a $10 million maintenance reserve. The September 2016 equity sale transferred interests from an LS Power affiliate to Marubeni and Sumitomo, but the cited announcement disclosed no sale consideration; that transaction value is therefore distinct from the project financings. — LS Power Completes Financing for West Deptford Energy Station - LS Power · confidence: medium
