- Financing summary: No closed project-level debt or tax-equity amount or lender is identified in the available project materials. The public PPA requires financing commitments sufficient to construct the facility and permits tax-equity or portfolio financing, but its financing provisions do not disclose executed financing terms. A secondary project profile reports an estimated project cost of $107.8 million; this is a project-cost estimate, not sale consideration or a financing amount. — High Desert Solar Project, US · confidence: medium
