EETN Completes upgrades to Carl Vinson VAMC Electrical Distribution system

New Switchgear and 2.5 MW Emergency Diesel Generator

New Switchgear and 2.5 MW Emergency Diesel Generator

EETN completed a 1 year project to upgrade electrical distribution system and emergency power generation for the Carl Vinson VAMC in Dublin, GA. The project included installation of a 2.5MW diesel generator and switchgear that incorporated parallel operation with the sites currently installed 2.5MW diesel generator. The install also included controls for the 21 additional emergency generators on the campus in a power and load shed scheme that maximized the ability of the hospital to withstand extended utility power outages.

“This was a challenging new endeavor for our team. Most of our business is in solar PV installation, but the similarities between solar PV and emergency power generation gave us the confidence to strike out on this new path.” said Terry Hamer, EETN Director of Operations “This project went relatively smooth. It is a testament to the quality of people we have solving problems every day.”

The project was completed in partnership with Nixon Power who supplied the switchgear, generator and technical support to prepare the EETN for success.

EETN starts construction near Gastonia, NC.


EETN breaks ground on 5.9MW solar PV project near Gastonia NC.  "We are very pleased to develop a new relationship with Enerparc.  Their professional and capable staff have helped us get a quick start on this project" says Robbie Thomas, EETN President.  

The project is a 5.9MW SolarFlexRack TDP 2.0 single axis tracker. EETN is the electrical and civil sub contractor for this project slated for completion by September 17th.  

EETN to Commission Northern Cardinal Solar Project

EETN started construction on the Northern Cardinal Solar Project on September 25th 2017.  The crew on site reached mechanical completion prior to the new year and is expecting to commission the array in April. 

EETN is an excellent option for small utility scale projects.  EETN is able to assume the entire scope of the project and prevent issues that can often arise from multiple trades operating in a small area. 

NABCEP certified Inspector


EETN's Matt Caldwell is the first professional in the state of Tennessee to obtain NABCEPs certification for Photovoltaic System Inspector.  "This is really great for Matt. I'm proud of our team and our dedication to constantly improving our knowledge of solar PV installation, testing and maintenance.  I really can't say enough about how impressive an accomplishment this is for Matt." - Robbie Thomas, President

EETN and partner Valcor Solutions completed work on 10.8MW solar PV installation for the Eastern Kentucky Power Cooperative in Lexington, KY.  EETN/Valcor were the electrical, pile and civil subcontractor for the general contractor Lendlease.  The fixed tilt portion of the project was SolarFlexRack G3X and the single axis tracker was ATI.   This project was an exercise in handling difficult subterranean characteristics that affected civil and pile structural design. 

"This project was very challenging on our pile team.  The geotechnical analysis showed shallow bedrock that ended up preventing 35% of driven piles from reaching minimum embedment.  We poured concrete for 554 spread footers for driven piles that did not meet required embedment.  The team handled the extensive remediation in stride enabling project completion on schedule." - Terry Hamer, Director of Operations.

As part of their ongoing relationship with Lendlease, EETN has started construction on a 2.5 MW DC solar PV system near Roanoke Rapids, NC.  The ATI single axis tracker project is expected to be complete in less than 2 months. 

EETN is the electrical and mechanical subcontractor for this project.  "When we perform virtually the entire install, it is very easy for us to be flexible and continue to make progress despite any minor hiccups.  I think Lendlease appreciates our ability to do that and limit any conflicts between different trades.  EETN is able to shift personnel from one trade to another to enable effective progress." - Terry Hamer - EETN Project Manager

EETN completes first pile driving contract with less than 1% of piles needing remediation

EETN was awarded a contract to install 7MW DC by LendLease.  The installation was in Halifax NC and was scheduled for 3 months of site work.  EETN installed Solar FlexRack's G3X contour following racking system.  The installation included 2400 driven piles for racking mount.  EETN's pile driving team completed the project with 5 piles needing remediation. 

"I am extremely impressed with what the team was able to accomplish.  We took on a task that was relatively new to us and our team was nearly perfect on the first attempt. I can't say enough about the quality of people we have at EETN"   - Robbie Thomas, President

The EETN team reached mechanical completion of this project on March 31, 2017. 

EETN completes 132 kW Parking Canopy - Verde at Greenbelt, MD

Commissioned October 22, 2016

Commissioned October 22, 2016

EETN install team commissioned this 132 kW DC - 98 kW AC system last week.  EETN was awarded a subcontract to perform racking, module and electrical install in June 2016.  The parking canopy is installed on top of a 5 story parking garage at the Verde at Greenbelt luxury apartment complex in Greenbelt, MD.  The location of the array presented significant difficulties in array install.  The innovative install team at EETN completed the array with 5 weeks of on-site work.  There was a short delay in work while the install team waited on the apartment's electrical equipment room to be completed. The parking canopy is a critical component in the apartment complex being a LEED Gold Certified building. 

EETN is very pleased to be a part of LendLease's construction team and very proud of our contribution to completing this LEED Gold Certified project. 

EETN completes Microgrid project in American Samoa

EETN recently completed a 94 kW parking canopy project at the Fiatele Teo Army Reserve Building in Pago Pago, AS.  EETN was the EPC contractor for this micro-grid project.  Pago Pago is located on the island of Tutuila.  The island of Tutuila is powered by several diesel generators and Solar PV power.  The Grid on the island is small – approximately 20 MW of peak load.  As additional Solar has been installed on the island, the local utility -American Samoa Power Authority (ASPA) has found it difficult to adjust equipment in the event of a cloud related power transient.  As a result, ASPA requires battery back-up and power smoothing function for installs greater than 30kW on the island. 

EETN designed a system utilizing the Princeton Power DRI-100 Inverter to provide the power smoothing function in the event of a cloud related power transient on the system.

In addition to the micro-grid aspect of this installation, The customer desired the ability to clean the panels with a temporary walk way.  With the space available, EETN was able to devise a less expensive option and instead provided a scissor lift and panel spacing to enable regular cleaning.

The corrosive salt spray environment required significant consideration for corrosion prevention.  EETN designed a system using PVC and stainless steel hardware on a hot dip galvanized structural steel frame to prevent corrosion.

EETN's superior design team and install crew including Young Energy Solutions, completed a very effective install.
