The latest lease awards cover schemes proposed by Scottish Power Renewables and SSE Renewables off the Argyll coast, the Beatrice Offshore Wind Farm in the Moray Firth, and projects by Repsol Nuevas Energias UK and Mainstream Renewable Power on the east coast.
The agreements give developers an option to take up seabed leases in the future. Their proposals remain subject to final consent by regulator Marine Scotland.
"We will continue to work closely with the Scottish government and developers to progress projects and attract investment, with the aim of helping meet Scotland's ambitious targets on renewable energy production," said Crown Estate Scottish commissioner Gareth Baird.
Baird said the organisation has already invested £16 million in offshore renewables in Scotland and will spend another £20 million over the next five years to support environmental studies, stakeholder engagement and other activities that reduce financial risk for promoters.
