Southern Power has signed a series of virtual power purchase agreements (VPPAs) with seven buyers for the project’s output. A further unnamed “large healthcare company” was also identified as offtaker for the remaining 20MW of capacity. This multi-buyer approach was coordinated by the Sustainability Roundtable, a US-based platform that aims to facilitate such deals through its ‘Net Zero Consortium for Buyers’ (NZCB) structure. Southern Power has already signed an offtake agreement for the third phase of the Millers Branch project, with a capacity of 132MW, which also uses the NZCB structure, with Synopsys and Keysight signing VPPAs for the project’s output. Sustainability Roundtable notes that its NZCB structure has facilitated deals for 1GW of renewable energy capacity and plans to add another gigawatt of capacity in the coming years.
