Details

This report presents levelised costs for electricity generation technologies. A ‘levelised cost’ is the average cost of the lifetime of the plant per MWh of electricity generated. They reflect the cost of building, operating and decommissioning a generic plant for each technology.

The report details the methodology, data and assumptions used to generate the levelised cost estimates.
