Our story

Haventus was born out of the vital need for port space to support large-scale deployment of offshore wind


Haventus is founded in 2023, one year after ScotWind, the world’s largest offshore wind leasing round


Offshore wind energy development in Scottish waters


Capital commitment by Quantum Capital Group

The company was founded following the huge success of the 2022 ScotWind offshore wind leasing round, which approved approximately 28GW of offshore wind development off Scotland’s North Sea coasts. The ScotWind and INTOG programmes will deploy around 35GW of offshore generation capacity in the next decade, moving Britain decisively towards net zero. The deployment creates an urgent need for major energy infrastructure in Scotland and the UK.

The first Haventus energy transition facility is currently under development at Ardersier Port. When completed, it will transform Scotland’s largest brownfield port into a world-class facility for the deployment and servicing of offshore wind installations. Learn more about the facility here.

Ardersier Port boasts a prime location on the Moray Firth. It represents an operational model that Haventus will seek to replicate across the world, to help enable a greener, net zero future globally.

Haventus is owned and controlled by Quantum Capital Group, a leading global provider of private capital to the responsibly sourced energy and energy transition & decarbonisation sectors. Together with its affiliates, Quantum has managed more than US$24bn in capital commitments under stewardship since inception. For more information on Quantum, please visit
