Key takeaways

  • Cisco, United States Cold Storage, and Daimler Truck North America are among early adopters of GSA Express, showing strong cold chain and manufacturing participation.
  • GSA Express allows large fleets subscribe to renewable capacity from Duke Energy’s grid and match up to 100% of annual electricity use without building off-site generation.
  • More than 177.3 MW of energy have been subscribed, with capacity reserved annually, giving large logistics and cold chain operators scalable access to renewable energy.

Duke Energy recently launched its Green Source Advantage Express program for large business customers in North Carolina. The company, which provides electric utility services and energy programs, developed the program to give nonresidential customers a streamlined way to access renewable energy capacity on its grid.

The voluntary program allows participants to subscribe to capacity from new renewable energy facilities and match up to 100% of their annual electricity use without securing off-site generation independently. Early adopters include Cisco, United States Cold Storage, and Daimler Truck North America, highlighting strong participation from companies with significant cold chain and logistics operations.

GSA Express has exceeded initial enrollment targets, reaching 177.3 megawatts (MW) subscribed and allocated across Duke Energy Carolinas and Duke Energy Progress territories. The structure also reserves 10% of additional capacity each year for new business customers, supporting ongoing access for large operators, including those with cold storage and manufacturing footprints.

To support emissions tracking and reporting, Duke Energy has introduced an Environmental Attribute Tracking tool in partnership with Cleartrace, enabling verified tracking of clean energy attributes and associated carbon reductions for participating customers.

"US Cold has set clear climate goals, including a commitment to source 100% renewable electricity by 2030 and science-based carbon reduction targets that have been independently validated,” Michael Lynch, SVP of sustainable engineering and automation for United States Cold Storage, stated. “Programs like Duke Energy's GSA Express help us advance those commitments in a practical way, alongside investments we're already making on-site, such as the solar installation at our Lumberton facility. Together, these efforts reflect our long-term approach to building a more resilient, sustainable cold chain network."
