The cited transaction announcements do not disclose project-level sale consideration or named financing parties. Potentia reported that tax equity and long-term debt were already in place with unnamed top-tier financing parties; the $768 million Repsol–ConnectGen transaction was a corporate-platform acquisition, not stated consideration for Sun Streams 1. The cited project-specific histories contain no separate milestone for expansion, repowering, retirement, or a storage addition to the original Sun Streams 1 asset; later Sun Streams projects are separate assets. --- Canonical page: https://askthegrid.com/assets/facilities/sun-streams-llc Source: Ask the Grid — https://askthegrid.com/
