About Project
Texas-New Mexico Power (TNMP) decided to upgrade the Caddo and Heights 138kV substations to accommodate the increased power flow (approximately 100MW) into the TNMP’s transmission grid from a new cogeneration plant of a large industrial customer.
The project team, MADERO and Sargent & Lundy Engineers, were responsible for the design and modifications of transmission and distribution, and substation structures, systems and components, as well as the Construction Management of the project.
The project scope of work included the installation of new 138kV dead end towers, gas circuit breakers, potential transformers, line positions, re-bussing of substation rings / line conductors, replacement of existing ring switches, wave trap replacement, as well as foundation work for the dead end towers and gas circuit breakers.
The project team designed and modified 345kV, 138kV, and 69kV lattice transmission towers, substations, dead end structures, wave trap support structures and bus support structures.
