Duke Energy Progress has issued green bonds totalling $600m to finance renewable energy projects including the development, construction and procurement of solar generation in the Carolinas.
The issuance is the second green bond by a Duke Energy subsidiary, with Duke Energy Carolinas having issued $1bn in November last year.
The latest green bonds were priced at a 3.45% fixed-rate coupon and have a 10-year maturity.
Underwriters included banks Academy Securities and CL King and Associates, Duke said.
Duke Energy chief financial officer Steve Young said: “We are providing our customers and communities with ever-cleaner energy – and these investments help us get there even faster as we expand renewable energy across the Carolinas.
“We saw strong interest in our first green bond last year and are excited to expand these offerings for investors.”
Academy Securities chief executive Chance Mimms said: “This was an exciting opportunity to support Duke Energy’s investments in green energy as well as its strategy to advance diversity and inclusion.
“As an investment bank owned by disabled veterans, we are proud of the business community’s efforts to bolster awareness of firms with diverse backgrounds and look forward to seeing this focus further develop.
“As we look ahead, we plan to invest in clean, green generation sources into the future and will continue to look for innovative options to finance these projects with diversity-owned firms.”
