H-1B sponsorship profile: Calpine Corporation. Across U.S. Department of Labor LCA disclosures, Calpine Corporation filed 58 Labor Condition Applications covering 58 H-1B worker positions between fiscal year 2023 and fiscal year 2026. The employer’s DOL certification rate sits at 96.6% (56 certified of 58 filed), a useful proxy for how cleanly their prevailing-wage attestations pass the Labor Department’s preliminary review before USCIS adjudication.

Compensation spread. Offered wages on Calpine Corporation’s H-1B petitions range from $115,000 at the low end to $200,000 at the high end, with a petition-weighted average of $141,844. That range reflects the mix of occupations the company sponsors, led by IS Analyst III (9 petitions at $125,157 avg), followed by Senior Integrator/Developer and Senior IS Analyst. H-1B salaries reported on LCAs must meet or exceed the DOL prevailing wage for the role and worksite, so the spread also tracks wage-level geography and seniority.

Geographic footprint. Calpine Corporation is headquartered in Houston, TX under NAICS code 2211, and places H-1B workers across 4 states, most heavily in TX, CA, NY. Combined, these signals give a granular view of how one employer uses the H-1B program, volume, approval cleanliness, wage posture, and where the jobs actually sit on the map.

Where Calpine Corporation ranks. By H-1B petition volume, Calpine Corporation is #4,070 of 119,880 employers nationally and #582 of 12,542 employers headquartered in TX. Both ranks are computed live from the same underlying petition counts, not a separate estimate.
