Power Generation Electrical Construction

Electrical construction for power generation facilities. Simple-cycle and combined-cycle gas turbine plants, peaker plants, cogeneration facilities, and emergency standby generation. We install the electrical systems that connect generating units to the switchyard and the grid. Generator leads, isolated phase bus, step-up transformers, switchgear, excitation system wiring, control cable, and complete site electrical.

Generator Connections and Main Power

Generator lead installation at 13.8kV and 18kV, isolated phase bus (IPB) rated for generator output currents, main step-up transformers, auxiliary transformers, MV switchgear, and generator breakers. High-current, high-reliability connections that must be right the first time. These are the primary power paths from the generating unit to the grid.

We handle the receiving, rigging, setting, and termination of large power transformers and switchgear. Oil processing, vacuum filling, and electrical testing coordination. The main power path is not the place for shortcuts.

Balance of Plant Electrical

480V MCC and 4160V power distribution for BOP systems: cooling water pumps, fuel gas systems, lube oil systems, HVAC, compressed air, and fire protection. Lighting, grounding, cable tray, and conduit systems. Complete site electrical for everything outside the turbine package.

A generating facility has dozens of auxiliary systems that all need reliable power. We install the distribution infrastructure that feeds them. Panel boards, disconnects, motor starters, and the cable and conduit that connects everything.

Switchyard and Grid Interconnection

Generation switchyard construction. HV breakers, disconnect switches, bus work, protective relaying, SCADA, and utility tie-in. This is the same switchyard and substation construction scope we perform on utility projects, applied to power generation.

We coordinate with the transmission owner and the independent system operator on interconnection requirements. Revenue metering, relay coordination, communication systems, and the physical connection to the existing transmission grid.
