Troy Solar

The 50-megawatt (MWac)/64.7-MWdc photovoltaic Troy Solar power plant uses First Solar 440-W thin-film photovoltaic (PV) modules and consists of approximately 150,000 solar panels distributed across 300 acres.

Each panel is mounted on a single-axis tracking system, enabling the panels to automatically shift to maximize energy generation.

We integrated construction capabilities with overall solar delivery to leverage our track record of multidisciplinary, utility-scale construction execution. This approach streamlined project delivery with parallel engineering, procurement and construction activities. The Troy installation is among the largest single-sited solar farms in the area and will support surrounding communities for decades. It can produce clean, efficient solar power for over 12,000 homes.

By working simultaneously on design, procurement and construction, we were able to design, procure and mobilize quicker than a traditional design-bid-build delivery method. Our integrated construction approach supported constructability reviews to address potential conflicts during the design phase. It also allowed seamless execution from conception through commercial operation.

Embarking on a Utility-Scale Solar Project to Meet Emission Reduction Goals

To continue to provide reliable service, CenterPoint Energy needed a new 50-megawatt alternating current (MWac)/64.7-megawatt direct current (MWdc) u...

Drone imagery and mapping was used to obtain preliminary topography information, allowing the site design team to conduct the preliminary site assessment and acquire as-built data for piling data development. Pairing data developed during the structural design phase with GPS-equipped pile-driving equipment improved efficiencies significantly. Drone imagery was also used for progress documentation throughout the project. While on-site, mobile applications supported safety management, daily reporting, quality forms and more.

Safety, one of our core principles, was a top priority, and the project was executed with more than 164,000 safe work hours with zero days away and zero lost time incidents.
