Select Projects
161kV GIS Substation Project
Design 161kV electrical service for a new chlorine gas production plant in Tennessee. The project added a 161kV power feed from TVA. Included in the scope were two 4160V services consisting of specially designed transformers that would provide DC power to the plant process. The 161kV power was distributed via a gas insulted switch (GIS) with switching capability that allowed half the plant processes to be running while the other half was maintained. ASSET’s design responsibilities included a protective relay panel design, power and control cable selection and routing designs, and control and monitoring communication system design.
Enterprise Products
ASSET Engineering was responsible for the Electrical and Relay Engineering scope of the project. This work included developing all electrical drawings, performing all electrical studies (short circuit, protective device coordination, and arc flash), determining relay settings, designing substation relay panels, and performing design reviews of OEM supplied electrical equipment.
Permian Basin 138kV Ring Bus Project #1 (Permian Basin, TX)
The Permian Basin of West Texas is one of the largest and most active oil basins in the United States. The area’s assets include over five million acres, as well as over 12,000 oil and gas wells, and infrastructure. The low cost of extraction in this area provides the basis for companies to be competitive, even during times of low oil prices.
The project owner continues to invest in their infrastructure in the Permian and in 2015 engaged our client, Dis-Tran Packaged Substations, to engineer, procure, and construct (EPC) a new substation. The new substation includes the design of an incoming 138kV ring bus, with two incoming lines and two service positions. The two service positions feed 45MVA transformers that step the voltage down to the 24.9kV distribution voltage. In addition to the new substation design, the project also provides for the distribution feeders to service several new gas compressor stations and service production pumps.
ASSET’s scope of work in support of this project included all of the detailed electrical engineering and design, protection and controls design, ground grid design, fault studies, relay settings as well as the programming of the relays and station monitoring devices.

Cameron LNG (Hackberry LA)
The Cameron LNG project is a $10 billion natural gas liquefaction facility expansion that will provide for the ability to import and regasify product for distribution domestically, export domestically sourced product, or re-export foreign sourced LNG to other countries.
The expansion at the existing terminal drove the need for an additional utility substation and a new site based switchyard to service the terminal. A joint venture between Chicago Bridge and Iron and Chiyoda International Corporation (CCJV) was successful in capturing the engineer, procure, construct (EPC) contract for the overall terminal expansion which included the new switchyard. CCJV chose to outsource the switchyard work in a separate EPC contract which was awarded to our client, Aubrey Silvey Enterprises of Carrolton GA.
The switchyard design includes the addition of six 230 kV circuit breakers from a new utility substation featuring three breaker and a half points of delivery to serve six new breakers. Each of the new breakers serves a new 84 MVA transformer feeding new 34.5 kV switchgear. Design priorities included interfacing connections and coordinating protection with the utility and the switchgear.
ASSET’s scope of work in support of this project included all of the detailed electrical engineering and design, protection and controls design, ground grid design, fault studies, relay settings as well as the programming of the relays and station monitoring devices.
WestRock Fernandina Beach Plant (Fernandina Beach Plant, FL)
WestRock is an American corrugated packaging company, is the 2nd largest packaging company in the United States and one of the largest paper and packaging companies globally with $15 billion in annual revenue and 42,000 employees in 30 countries. The Fernandina Beach plant is one of the largest WestRock linerboard mills, with the most productive liner machine in the WestRock system. The Fernandina Beach Plant occupies 216 acres and its 480 employees produce 900,000 tons of paper (8% of WestRock’s total production) each year.
• Arc Flash
• Short Circuit and Protective Device Coordination – including settings
The mitigation scope was focused on their DC Drive rooms. Which required providing a design for a protective relaying option for reducing the arc flash hazard room. The solution included the addition of arc sensor relays with overcurrent supervision to trip upstream breakers to shorten the fault duration. In early 2019, WestRock engaged ASSET to implement the engineered solution identified for the first group of 37 drives. The second phase of our work involved designing same solution for the protection for 31 transformers feeding the drives.
Hu Honua Biomass Plant (Hawaii)
30MW Biomass Facility
This facility was an old sugar mill located on the “Big Island” in Hawaii that is being repurposed as a biomass energy plant producing 30-megawatt (MW) electric power using locally grown eucalyptus biomass as the fuel source.
Green Power Solutions Power Plant (Dublin, Georgia)
34MW Biomass Facility
This project was a joint venture between ASK Partners and SP Fiber Technologies to install a new cogeneration facility on site at the SPFT paper mill in Dublin Georgia. The new plant provide 34MW of base load power to the Georgia Transmission grid while also providing steam for use in the processing of recycled fiber. In order to take advantage of the renewable resource aspect of the steam generation at the SP Fiber Technologies Facility, the generation connected to the SPFT 138kV Bus needed to be reconfigured to connect to Georgia Transmission 138kV Facilities. Additionally, the new entity owning and operating the Steam Turbine, Green Power Solutions (GPS), planned to upgrade the Turbine Control System while also replacing the 1950s vintage protective relays with modern relaying technology.
ASSET worked with the New Turbine Control Vendor to coordinate the implementation of the new primary and back-up generation protection relays. This work included development of the protective settings for the new SEL-300G relays, oversight of FAT, and management and oversight of commissioning.
Nippon Paper (Port Angeles, Washington)
20MW Cogeneration Facility
Updated the electrical system model for auxiliary and generator additions. Evaluated operating modes for the generator, load flows were calculated at different production and levels and initial voltage and power factor settings were recommended. System coordination and protective relay settings were reconfigured throughout the system for the new generation source. Arc flash hazard study was performed for all generation system additions. Developed a protection and controls design and relay settings for the 69 kV substation, and developed a test and energization plan for the entire system.
Resolute Forest Products (Augusta, Georgia)
New 13.8kV Power Distribution Line
ASSET provided the engineering and design for a new 13.8 kV distribution line routing including, development of plan, profile, pole top assembly details, guying and grounding details, material list, pole strength and buckling calculations and sizing. ASSET also provided sag-tension tables for the installation of 336 MCM ACSR phase and 1/0 ACSR shield conductors.
TR Miller (Brewton, Alabama)
Electrical Studies
ASSET performed an arc flash study and provided the labels for equipment throughout the extensive electrical system of this large mill. The sawmill, planer, kiln, pole mill, lattice, and office areas were all inspected and data was collected for the plant’s power distribution system. Single line diagrams were created in AutoCAD from the inspection and field data collected during the investigation phase in order to provide the mill needed documentation for maintenance and a basis for future mill upgrades and expansions. The short circuit levels were investigated on each bus and through each system branch; all equipment was found to be operating within its design limits. Time-current coordination work yielded a recommendation to change and add 480V breakers and transformer primary fuses to speed tripping after a fault and to minimize the equipment affected by an unplanned outage. TR Miller also requested, and ASSET performed, a study of the harmonic currents and voltages suspected for the misoperation and failure of variable frequency drives. The study found no significant harmonics issues and through further due diligence the root cause was determined to be a grounding issue.
Interfor (Formerly Price Lumber Company) (Monticello, Arizona)
Electrical Studies
ASSET performed a number of electric studies for this client. The initial phase of work required the collection of equipment data in all areas of the facility including, the sawmill, kiln, planer, office, and log yard. This data facilitated the development of an electrical system model and updates to the mill’s AutoCAD single line diagrams. With this electrical system model, a comprehensive arc flash hazard study was conducted which provided an assessment of arc flash energies and needed personal protective equipment (PPE). Another element of work at this mill involved the measurement of load and harmonic currents and voltages to aid in the failure of an existing capacitor bank which had been switched out of service. Additionally, a reactive power compensation study was performed. The end result of the harmonics engineering effort was a technical recommendation for a filtered capacitor bank and financial payback calculation.
Southern Chips (Perry, Arizona)
Arc Flash Study
ASSET Engineering provided an arc flash study for this client. ASSET personnel collected the necessary field data to perform the study and then modeled the 4160/480/240/208V systems, and determined the arc flash energies and PPE needed for each piece of operable electrical equipment. The project concluded with the ASSET engineer assisting in the application of arc flash labels and providing training to the mill electrical staff.
