RSI's Brightfield One Solar Project


Brightfield One, 200 kW solar photovoltaic array, is the first phase of RSI’s Brownfields to Brightfields initiative. The initiative has been a natural expansion of our extensive experience characterizing, permitting, and restoring "Brownfield" sites (government or industrial sites with restricted future use). We have leveraged this experience along with our proven project management capabilities and our firm's success as an environmental services company to facilitate reuse of Brownfield sites for solar power generation. The design for Brightfield One was developed by the RSI team as an outgrowth of our technical guide created specifically for the installation of solar farms on restricted-use sites. The guide was produced through a grant awarded to RSI by the Tennessee Solar Institute and funded by the American Recovery and Reinvestment Act.

Brightfield One is located on a one-acre tract at the East Tennessee Technology Park (ETTP) that RSI purchased from the Community Reuse Organization of East Tennessee (CROET). ETTP is the site of a former U.S. Department of Energy (DOE) Gaseous Diffusion Plant that is undergoing revitalization efforts. RSI self-financed the project, used solar panels manufactured in Tennessee, and partnered with other local small businesses for the installation.

Power generated from Brightfield One is being sold to the Tennessee Valley Authority (TVA) through the City of Oak Ridge Electric Department using a Generation PartnersSM contract.

  • The 200 kW array can produce enough energy to power 22 homes per year - equivalent to 422,745 pounds of carbon dioxide or the annual greenhouse gas emissions from 34.6 passenger vehicles
  • 828 SHARP® 240 watt modules feed two Advanced Energy® PVP 100 kW inverters that turn direct current into the alternating current used in homes - total system capacity is 198.72 kW
  • TerraFix racking systems are used to ground mount the array structures with a series of 5-foot long "earth screws"
  • SPX® ArgusOn web-based, real-time monitoring provides detailed performance and evaluation capabilities

The next phase of RSI's Brownfields to Brightfields initiative is the development of utility-scale solar farms on restricted-use property. RSI’s solar team is developing several potential projects for this next step as we continue to scale up our renewable energy portfolio. We are promoting our vision of supporting the national clean energy goals through the natural and thoughtful use of these sites.
