South Carolina Electric and Gas and Boeing have officially marked the completion of one of the largest single rooftop solar installations in the United States and the largest in the Southeast, by production capacity.

The dedication event signaled the start of renewable energy being generated by the 2.6-megawatt D.C. rooftop photovoltaic system, which is made up of more than 18,000 thin-film photovoltaic solar laminates that cover 10 acres on the roof of the 14-acre Boeing South Carolina 787 Final Assembly building.

"This project is a classic example of working with our customers to supply their energy needs, but with a new twist," said SCANA Chairman and CEO Kevin Marsh.

"SCE and G for the first time is supplying a facility with 100 percent green power. I commend Boeing for their commitment to sustainability and for the opportunity they presented us to supply this site with renewable power."

The 2.6 megawatts of electrical power generated for the site is enough to power approximately 250 homes. SCE and G began installation of the photovoltaic panels May 16, the same day Boeing teammates began moving into the building. Substantial completion was met Oct. 28.

Under the arrangement with Boeing, SCE and G will own and maintain the solar generation system and will supplement the solar-generated energy with power from its system resources, coupled with green attributes from its North Charleston biomass generator, to meet all of Boeing's energy requirements.

The solar installation on the roof will provide clean, renewable power for the Boeing site, and all of that power will stay within the Boeing site.

"SCE and G is proud of its partnership with Boeing to provide the technology and the energy for the company's only location in the world capable of assembling commercial aircraft with 100 percent renewable energy," said Jim Landreth, SCE and G vice president of fossil/hydro.
