Budget estimate

$500,000 – $2,000,000

Based on typical costs for underground utility installation tied to solar projects of this scale, the contract is likely to fall within the low‑to‑mid‑hundred‑thousands to low‑single‑digit‑million dollar range. Factors influencing the estimate include trench length, conduit material, voltage level, site terrain, and required safety and certification compliance. A reasonable estimate would be between $500,000 and $2,000,000.
