Mainstream Renewable Power

What Mainstream Renewable Power does

Mainstream Renewable Power is a pure-play utility-scale renewable energy developer founded in 2008 in Dublin (now headquartered in Oslo) that develops, constructs and operates onshore wind, solar PV and battery energy storage projects across South Africa, Chile, the Philippines, Australia and South Korea. The company has delivered 6.6 GW of wind and solar generation assets to financial close-ready status and maintains a 13 GW net global pipeline, with the Global Development Standard functioning as the codified, gate-based process that ensures bankable project delivery across markets. Its technology stack combines renewable generation assets (including the 1.37 GW Andes Renovables hybrid platform in Chile and the 109.2 MW Ckhári wind farm) with operational AI applications for site selection, turbine layout optimization, computer-vision wildlife monitoring and AI-driven inspections. Mainstream has raised more than EUR 3.0 billion in project finance and is majority-owned by Aker Capital AS (Aker ASA subsidiary) with Mitsui & Co. holding a 27.5% strategic stake acquired in March 2022 at a EUR 2.1 billion valuation.

The company monetises through long-term (typically 20-year) Power Purchase Agreements with government agencies such as Chile's National Energy Commission, corporate PPAs with industrial off-takers (e.g., Sasol and Air Liquide in South Africa), and shorter 5-10 year Renewable Energy Supply Agreements for commercial and industrial customers via the Ilikwa product. A second, recurring capital-recycling revenue line comes from developing projects to financial close and divesting portfolios to other developers or infrastructure funds (e.g., the 675 MW Colombian portfolio sold to Celsia in April 2025, the announced A.P. Moller Capital acquisition of Mainstream South Africa in June 2026). Operational asset management is delivered through subsidiaries including Mainstream Asset Management South Africa (MAMSA), and large projects are pursued via consortium structures that share capital intensity and risk (Ocean Winds for KF Wind South Korea, Gippsland Skies consortium for the 2.5 GW Australian offshore wind project).

Revenue model

1. Power Purchase Agreements (Government): Long-term (typically 20-year) contracts with government bodies to supply renewable energy, such as the Andes Renovables platform supplying 3,366 GWh annually to Chile's National Energy Commission.
2. Corporate Power Purchase Agreements: Tailored PPAs for private sector customers including Sasol and Air Liquide, providing decarbonisation solutions through 20-year agreements for large energy users.
3. Renewable Energy Supply Agreements (RESAs): Flexible shorter-term energy contracts (5-10 years) providing renewable power to commercial and industrial customers through the Ilikwa product, opening access for mid-market businesses.
4. Project Development and Divestment: Developing renewable energy projects to financial close-ready status and divesting portfolios to other developers (e.g., sale of 675 MW Colombian portfolio to Celsia), enabling capital recycling.
5. Asset Ownership and Operations: Ownership and operation of renewable energy assets generating electricity for sale under long-term contracts and merchant exposure.
