<h3 class="wp-block-heading">The 373.8 MW Logan County repower project is located in Logan County, Colorado. Blattner’s scope consisted of the mechanical overhaul of 214 existing turbines which was completed in two phases. </h3>



Phase one consisted of the mechanical overhaul of the existing 133 GE 1.5MW WTGs, including turbine blades, hub assemblies (including nose cones), gear boxes, main shafts, main bearing assemblies, generators and generator frames. The turbines were converted to 133 GE 1.5MW WTGs. Phase two consisted of the mechanical overhaul of the existing 81 turbines including turbine blades, hub assemblies (including nose cones), gear boxes, main shafts, and main bearing assemblies. The turbines were converted to 66 Siemens 2.3 MW WTGs and 15 GE 1.5 MW WTGs.



This project was the first site to actively screen for COVID-19 and was diligent in protecting the site team, putting safety first. A key factor in the success and safety of the project was the immediate implementation of a night crew to work when winds were calmer. The night crew pulled and disassembled old rotors and built and flew new rotors. There were many shifts where the night crew flew three rotors in a shift on different crane pads. Day crews gutted the nacelles and replaced components during marginal wind, allowing the night crew to focus solely on rotor assembly and installation. The team outpaced GE commissioning by 15 or more towers as the dedicated team worked well together. This project was a testament to what can be accomplished with solid planning and teamwork.

Blattner Repower Project

Blattner completes significant repower project

Hurricane Laura decimated Entergy’s transmission system on the gulf coast of Louisiana.&nbsp; Entergy awarded 10 transmission lines of varying voltages (69kV-500kV) to Quanta for an emergency rebuild. Highlighted below are two of the more critical projects



<ul>
<li>Two 500kV transmission lines – The most significant of Entergy’s damaged transmission lines were two 500kV lines that serve as the electrical backbone for the state of Louisiana.&nbsp; In addition to Entergy&#8217;s customers these lines feed multiple co-ops and several of the gulf coast’s largest refineries. Sixty-eight (68) structures along 11-miles of 500kV transmission line were destroyed. Quanta assisted Entergy in damage assessment, resourcing essential construction labor and equipment for the safe removal of the compromised towers and wire. The team also oversaw the staging, delivery and handling of all new structures and accessories, as well as the construction to restore the system, including adjacent 230kV, 138kV, and 69kV lines.&nbsp; A project of this size typically requires at least 8 to 9 months of careful planning, design, ROW, and procurement. Then, another 3 to 4 months to clear the damage and complete construction. Even with the effects of a 2nd hurricane near the construction areas, the Quanta team had Entergy’s lines ready to energize in under 40 days.</li>



<li>Mud Lake to Sabine 230KV – a critical line that serves one of Entergy’s largest industrial customers. This line had numerous challenges when it was handed over to Quanta in early September. Most of the line could only be accessed by barge or airboat and the intercoastal crossing needed to be completely rebuilt.&nbsp; Landowner issues, significant material delays, as well as two hurricane evacuations and added scope following a direct hit from a second hurricane threatened the progress of this critical line.&nbsp; Despite these numerous issues the Quanta team had the line back in-service 39 days ahead of schedule.</li>

Hurricane Laura Storm Response

Due to the existing transmission grid across the West and it increasingly operating at full capacity during peak periods of customer electric use, this project was jointly proposed by Rocky Mountain Power and Idaho Power. The scope was to build and operate approxi- mately 1,000 miles of new high-voltage transmission lines between the Windstar substation near Glenrock, Wyoming and the Hemingway substation near Melba, Idaho. PacificCorp’s project included approximately 150 miles of 230 kilovolt (kV) lines in Wyoming and approximately 850 miles of 500kV lines in Wyoming and Idaho. PacifiCorp owns and operates one of the largest privately held transmission systems in the nation. This new transmission line delivers electricity to meet increasing customer needs in Idaho, Wyoming, Utah and other Western states, providing strength and reliability to the region’s transmission system.



The project is comprised of two major line segments.



<ul>
<li>Windstar to Populus, Segment D, stretches approximately 488 miles starting at the Windstar substation near Glenrock, Wyoming, proceeding south to Medicine Bow and then spanning across southern Wyoming to the Populus substation near Downey, Idaho.</li>



<li>Populus to Hemingway, Segment E, originates at the Populus substation near Downey, Idaho, and includes two 500kV single-circuit transmission lines that run approximately 502 miles across Idaho to the Hemingway substation near Melba, Idaho.</li>
</ul>



Quanta Services companies executed the following:



<ul>
<li>QEPC provided overall project management, procurement and material management, project controls and Safety and Quality Assurance. QEPC’s detail-oriented management approach, dedication to safety excellence and commitment to total quality management allows us to effectively and efficiently manage complex EPC projects. Ultimately over 21.8 million pounds of steel, roughly 7 million feet of conductor, 33 steel H-frames, and three pole dead-ends were successfully procured and deliv- ered ahead of construction.</li>



<li>Our Environmental team provided real-time infor- mation on changing ground conditions related to protected environmental areas and species restric- tions. On-site environmental specialists provided assessments and input information to our real-time, online project management system, working with our Project Management team to make daily deci- sions regarding schedules and crew locations.</li>



<li>Summit Line Construction provided construction management, construction and craft labor for the project. Additionally, Summit leveraged additional resources from sister company, PAR Electrical Contractors. Construction crews had to work in a non-linear fashion that were dictated by biological and seasonal restrictions.</li>



<li>Quanta Subsurface provided foundation design of the lattice tower and 345kV steel pole foundations, inspections, and geotechnical services.</li>
</ul>



The Gateway West Transmission Line Project utilized a variety of different tower structures. The towers for each segment and area of the project depend on the location, topography and needs.



Throughout the project, our team was sensitive and conscientious of the cultural, archaeological, and paleontological discoveries. The challenges brought to the team by environmental restrictions, non-linear construction, weather, and governmental agency coordination were tackled head on, and very professionally.

<h2 class="wp-block-heading">Largest EPC project ever awarded in North America</h2>



The West Fort McMurray (WFMAC) 500 kV Transmission Line Project includes over 310 miles of high voltage transmission line, expansion of the existing Livock substation, and construction of the new Thickwood Hills substation, all located in Northcentral Alberta.

<h2 class="wp-block-heading">IRBY &amp; FPL ARE LEADING THE CHARGE ON BATTERY STORAGE.</h2>



Irby Construction is currently at work on site at Manatee Battery Energy Storage Center (BESS) and substation, which upon completion will consist of 132 new battery line-ups connected to a new 230/34.5 kV substation. The Florida Power and&nbsp;Light&nbsp;project includes placement of 53,144 individual&nbsp;battery modules on a site&nbsp;that is the size of 3 football fields.



When complete it will be the world’s largest solar-powered battery.



The 409MW/900MWh Manatee energy storage center, will accelerate retirement of fossil fuel generation, saving FPL customers more than $100 million while eliminating more than 1 million tons of carbon dioxide emissions.
