A rent model where the landowner is paid a guaranteed annual sum (usually per acre or per turbine), indexed to inflation. It offers certainty and stability, regardless of how the project performs. In the UK, fixed rents for solar are often £800-£1,200 per acre annually, while wind turbines can yield £5,000-£10,000+ per turbine per year (and often far more than this) Fixed rent works well for risk-averse landowners but doesn’t capture upside from high energy prices.
