The Portfolio Manager III (PM) is accountable for the long-term performance, reliability, and value creation of a portfolio of renewable energy assets. This role serves as the primary owner representative across operations, OEMs, service providers, and internal stakeholders, with authority to escalate issues, drive corrective action, and implement portfolio-wide improvements. Unlike junior and mid-level portfolio management roles, the Portfolio Manager III is expected to define strategy, challenge legacy practices, and materially improve asset outcomes, not simply administer contracts or track performance.
