Investing in the energy transition

Customised solutions delivering solid financial returns and strong climate action

Unique 35+ year track record

With over EUR 2.5 billion invested in the energy transition over the last three decades, we have established ourselves as a leading investor in the sector, closely linked to innovation and ongoing developments. We were the first commercial investor in onshore wind in the 1980s, we financed Europe’s first large-scale floating solar park and the Netherlands’ first stand-alone Battery Energy Storage System.

Integrated impact-risk-return framework

Our investment approach balances long-term financial performance with measurable positive impact. We apply an integrated impact-risk-return framework to all our investments.

Global network and steady deal flow

Through our extensive network of partners and portfolio companies, we maintain a robust pipeline of high-quality investment opportunities. For nine consecutive years, Clean Energy Pipeline has recognised Triodos as the lead arranger by number of clean energy transactions
