Budget estimate

$1,000,000 – $5,000,000

No budget is disclosed, but comparable underground electrical installations for utility‑scale solar projects typically range from $1 M to $5 M depending on length of conduit, voltage level, terrain, and labor rates in the Southwest. Assuming a moderate‑size solar site, the estimate would likely fall within that band, with higher costs if extensive trenching or high‑capacity transformers are required.
