Industrial & Commercial Projects
Facility Distribution Maintenance and Upgrades
Climax Mine, Leadville, Colorado, 2004-present:
The project responsibilities include developing record drawings for electrical distribution systems, removing unused electrical supply stations, developing maintenance standard operation procedures and performing maintenance and designing new systems as related to keeping the electrical systems operating. Electrical one line diagrams for the 13.8kV electrical distribution system and 480 volt pump stations were updated to reflect the existing plant operating conditions. An overall 13.8kV electrical distribution system one line and map drawing were developed to assist in day-to-day electrical system operation. Providing project design and coordination activities to keep an electrical maintenance crew of three to nine electricians working throughout the six month construction season at high elevation.
Bravo Dome CO2 Compression Station
Alliance Engineering, New Mexico, 2007-present:
Design of 15kV systems to power two 11,000hp gas compressors added to an existing 50MW plant. Work included switchgear building, coordination with VFD and motor manufacturer, design of duct banks and cable runs, specification of station power transformers, and integration new protection into existing systems. Study work included full plant loadflow model, short circuit and coordination studies, and arc flash study for equipment labeling and personnel protection.
Chipeta Phase II Gas Compression
Alliance Engineering, Utah, 2008:
Design of 34.5kV and 15kV systems for the addition of one 25,000hp compressor with VFD. Work included main substation connections and upgrades, 34.5kV distribution line, 30MVA main transformer and 4500kVA station power transformer, protective relay panels, and station layout. Study work included plant and distribution system load flow, short circuit, coordination, and arc flash.
Trailblazer Natural Gas Pipeline Compressor Stations 602 and 603
Kinder Morgan, Inc., Nebraska, 2001-2002:
Design and coordination of 15kV class compressor motors and associated systems, including switchgear, MCC’s, substation integration, and motor/VFD studies. Station 602 involved the addition of one 10,000hp motor and a change to operating an existing motor from 5,000hp to 10,000hp. Station 603 involved the greenfield installation of two 12,000hp compressor motors. Performed plant equipment testing observation for motors and VFD’s. Provided checkout and startup assistance at each site. Specified 15kV harmonic filter modifications and additions, and metered voltage and current harmonics for three months before and after upgrades to verify acceptable performance, include providing a report to the local utility and municipal government.
Cheyenne and Guernsey Terminal Pumping Stations
Suncor, Cheyenne, Wyoming, 2005-present:
Design, specification, construction contract preparation, bidding, construction and material coordination, and checkout and testing assistance for distribution substation upgrades at two oil pipeline pumping stations. Coordinated with local utilities for power supply upgrades, protection requirements, and flicker/motor starting limitations.
Distribution Center Equipment Failures
Ashland Oil, Denver, Colorado, 2006-2007:
The facility experienced a number of equipment failures: 480V motors burning up, 277V lighting failures, and truck scale electronic equipment failures. EEC investigated possible sources and causes of these failures. Power monitoring and recording equipment was installed at the main service entrance and recorded at various times over a period of nine months. Transient voltage events were tracked back to capacitor bank switching on the utility’s distribution line. TVSS technology providing surge suppression based on single-MOV technology was applied specifically to protect sensitive electronic equipment against catastrophically intense transient surges. The plant was able to return to operation and has not experienced any further equipment failures.
Printing Facility Additions
Frederick Printing, Denver, Colorado, 2005:
Several pieces of new printing equipment were added in the printing facility. The addition of this new equipment required upgrading the 480 volt electrical service to handle this additional load growth. The project was for design, specification and construction observation assistance relating to the electrical service upgrade of the facility 480 volt electrical service.
Architerra Group
Provided electrical design services for several park projects requirement park area lighting, shelter lighting and receptacles, and packaged pump stations for park irrigation systems.
