Holcim Cement Plant

St. Genevieve, MO

Mammoth Industrial Delivered in Award-Winning Style.

PayneCrest was saluted with an AGC Keystone Award for expertly managing the largest electrical contract ever in the region to power the mammoth Holcim Cement Plant. Sprawling over 2,900 acres, Holcim is the world’s largest single kiln cement plant with a more than one-mile-long production process producing four million metric tons of cement annually. The electrical package was its most complex element. Managing more than 400 electricians at its peak, PayneCrest provided 345,000 volts of power directly from the Ameren Rush Island Power Plant and built its entire electrical infrastructure.

“In size, scope and complexity, no project locally has ever required the intense electrical needs as the Holcim Cement Plant near Ste. Genevieve, Mo.” — Rudy Blum, project manager, Holcim (US) Inc.
