Adaptable Framework, Dynamic Experience


Plant Engineering

Our team has worked on projects totaling over 10,000 MW of generating capacity, with over 100 years of combined power sector experience. We are capable of turn-key projects, greenfield and brownfield projects, Design-Build and Build-Own-Operate. Our expertise includes HFO, LNG, Coal, Nuclear, and Renewable generation sources. Technical staff has worked on Western (GE, Siemens) and global turbine technologies (Wartsila and Russian makers).

Supply Chain

Based in California, our global supply chain services add value by ensuring that supplies of heavy-gauge wiring, buses, cabinets and control panels, switch-gear, replacement parts, construction material, custom fittings, built-to-order systems, air-handling fans, filters, motors and pumps and more are available as needed, reducing inventory cost. Our sourcing draws on relationships developed over the past 96 years as a division of WES-CO Industries.

Power Portfolio

We provide advisory services to power generation and power distribution clients, from Independent Power Producers to national governments and international organizations. Owning the infrastructure is only half of the equation - optimizing for base-load and peak demand are just as important. We deliver insights and incisive consulting, empowering decision-makers to act decisively assured with correct and accurate data and analysis.
