Harris worked with Standby Systems Inc to fabricate 13 skids for a General Electric propane vapor system to be installed in the country of Ghana, Africa. The skids, which were shipped internationally, contained piping, pumps, valves, heat exchangers, structural frames and supports for the metering and vaporization of the propane.
Framing and piping for the skids were constructed from 304 stainless steel, which quality specifications were required to meet the pressure equipment directive (PED) of ...

The Pepco Waterfront Substation project was a new substation installation for the Potomac Electric Power Company of Washington, D.C. It was a design-assist job with Coakley Williams Construction and their mechanical engineer, META Engineers. The building had to be designed to house and accommodate a new ABB turbine technology that Pepco was using to make power with a smaller footprint than their traditional power plants. The site in Southeast Washington, D.C. was selected because of its proximity ...

Harris worked as the prime contractor for Xcel Energy’s 5th Street Substation Transformer Cooling System Replacement project. The project involved demolishing the existing cooling system and installing an efficient, closed-loop system to service the new transformer.
Prior to the closed-loop system Harris installed, Xcel was drawing their cooling water from two deep wells. Xcel decided this system was not a sustainable use of groundwater and made plans to replace it.
Harris took special safety ...

Harris helped Novus Energy LLC design and build a mobile demonstration plant. The demonstration plant is a trailer-mounted, waste-to-energy conversion system which is fully integrated with its own automated control system. The system is a completely functional plant capable of converting high-solid organic materials to methane-rich bio-gas, organic fertilizer and clean water.
The demonstration plant has been used to showcase new technology and fine-tune the design configuration for full-scale plants. It has been operating since 2010 and has ...

Qteros is a biofuel startup that produces ethanol from various biomass feedstocks. The cellulosic ethanol fermentation pilot plant can produce about 1,000 gallons of ethanol from biomass sources such as wood chips and fibrous plant residues. Harris furnished equipment, design engineering and installation services, working closely with Qteros to integrate used owner furnished equipment and new equipment to build the pilot plant. Harris developed the process engineering and controls to match Qteros’ technology requirements. The project was closely documented to ...
