Projects
PYTHIAS SUBSTATION
CENTERPOINT ENERGY | BRAZORIA COUNTY, TEXAS
The Pythias Substation is a 345-kilovolt (kV) facility connecting the 125-megawatt (MW) Second Division Solar farm to CenterPoint Energy’s grid, delivering approximately 100 MW of clean energy and offsetting more than 155,000 tons of CO₂ annually. Its breaker-and-ahalf design and SCADA controls ensure reliable solar integration and local grid stability. Our firm handled civil design, permitting, construction support, and commissioning to keep the project compliant and on schedule.
DAMON SUBSTATION
CENTERPOINT ENERGY | BRAZORIA COUNTY, TEXAS
Damon Substation features a 12,500-foot distribution feed designed by DCCM to support the Brazoria West Solar Farm and substation construction. The scope included electrical distribution engineering, pipeline permitting, and easement preparation, with coordination across CenterPoint Energy’s transmission, substation, surveying, and right-of-way groups. The project was completed within the $700,000 construction budget and delivered on time to meet client deadlines.
NEW GULF SUBSTATION TO PLEDGER SUBSTATION
CENTERPOINT ENERGY | HOUSTON, TEXAS
DCCM providing engineering including design, permitting, and field measurements for aerial single-mode fiber optic cable between New Gulf and Pledger Substations. The scope included pole loading analysis, communication and makeready design, governmental permitting, and pole attachment applications. The project resulted in a reliable telecommunications connection that remains in service today and continues to perform to expectations.
