Berg joined Mainstream in 2024 as CFO and has led the strategic transformation of the company, including the move of HQ from Dublin to Oslo in 2025.

Before joining the company, Berg served as the CFO at Aker Carbon Capture (today SLB Capturi) and, prior to that, was a partner in KPMG.

Berg has international experience across many sectors.

Her in-depth knowledge of Mainstream, the sector, and the opportunities and challenges faced by the industry means she will hit the ground running, completing the optimisation programme and driving future growth.

Mainstream Renewable Power was founded in 2008 to develop utility-scale renewable energy projects in developing markets worldwide.
