In 2015, Southern Power completed the issuance of $1 billion of green bonds (Series 2015C and 2015D), becoming the first investment-grade power producer in the U.S. to offer this type of security to support investment in sustainable generation.

Below you can see the specific Eligible Green Projects to which Southern Power has allocated the green bond proceeds ($994.1 million), the environmental benefits of those projects (representing 100% of each project) and Southern Power's management assertion letter together with the independent accountants' attestation report.

Both Series 2015C and 2015D have now matured, but we still continue to show generation data from the projects the bonds funded.
