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.

Series 2015D Update

In November 2017, Southern Power’s Series 2015D green bond matured ($498.5 million proceeds). At issuance, Southern Power allocated $994.1 million of proceeds from Series 2015C and 2015D to three projects. Now that the Series 2015D has matured, we have re-allocated proceeds from Series 2015C to the Decatur Parkway Solar Facility and Kay Wind Facility, and no longer have any proceeds allocated to the Solar Gen 2 Solar Facility.

Solar Gen 2 Solar Facility
