Photovoltaic Permitting - 6/2018

8minutenergy, the largest independent solar power developer in the US, has retained TriAxis, a Division of David Evans and Associates for two photovoltaic (PV) projects.

Eagle Shadow Mountain Solar Farm: This PV project, the largest to-date built on tribal land, will be the second solar farm within the Moapa River Indian Reservation in Clark County, Nevada. When fully operational, the plant is estimated to generate more than 900 million kWh of electricity per year. The scope of services includes preliminary design of the 230 kV transmission line in support of obtaining Bureau of Land Management (BLM) rights-of-way for the interconnection to Nevada Energy.

Sienna Solar Project: This PV project will install a 300megawatt solar farm of approximately 95,000 solar panels. The scope of services includes developing preliminary site concepts to optimize the substation layout and location, and the 35 kV collection system routing. The scope of work also includes preliminary design of the 230 kV transmission line in support of obtaining BLM and Riverside County rights-of-way for the interconnection with Southern California Edison.

Ward Olson retires from TriAxis - 4/2018

Ward Olson (CRV) will retire Friday, April 27, 2018. Ward began his career in 1981 and was hired by TriAxis as a Senior Designer in December of 2000 to help with the designing of distribution and transmission lines. Ward will be greatly missed for his numerous design skills, including Rural Utility System (RUS) design, steel pole design, construction estimating and bid schedules, underground line design, field inventory, and joint use pole strength analysis. Among his accomplishments, Ward spent one summer traversing the Oregon State University underground tunnels to take inventories in the scorching heat of more than 110 degrees.

Techren Substation and Transmission Line Design, Nevada - 3/2018

Cyndee Pekar retires from TriAxis - 3/2018

“I will miss being a part of the logic and creativity that is engineering,” said Cyndee Pekar (CRV) as she reflected on her retirement. “I’m not an engineer. I provided engineering support, but I have always enjoyed listening to how engineers solve problems and what engineering means and does for people. There’s an excitement in engineering, of doing things to help people.” Cyndee officially joined TriAxis in 2007, providing administrative support and reconnecting with several colleagues she had worked with in the first 20 years of her career. Thinking over her years with TriAxis, Cyndee said, “I’ll miss the camaraderie, the people. That’s really the biggest thing.”

Faith Junghans of the Corvallis office said, “Along with her office skills, Cyndee’s cheerfulness, laugh, and compassion will be sorely missed!”

Mark Petrie (ABQ) said, “Cyndee has been a valuable member of TriAxis for over 10 years with contributions in the administrative department as well as project- and proposal-related support for our project managers.  Cyndee was well known to all of us even before her time at TriAxis since she worked with our original staff at her previous employer.  Personally, Cyndee and I joined TriAxis at nearly the same time in 2007, and she has been part of what I know as the TriAxis family since the day I started with the firm.  We will all miss seeing her in the office every day.”

When asked about what she is looking forward to in retirement, Cyndee said, “I’m looking forward to not having to get up at a specific time. To waking up, having a cup of coffee, doing the crossword and then figuring out what I want to do that day.” Having recently moved to Lebanon, Oregon, Cyndee anticipates helping out at the senior center. She also said, “I want to kick back and enjoy what’s around me. We really have an amazing state.”
